1 | systemd System and Service Manager | |
2 | ||
3 | CHANGES WITH 227: | |
4 | ||
5 | * systemd now depends on util-linux v2.27. More specifically, | |
6 | the newly added mount monitor feature in libmount now | |
7 | replaces systemd's former own implementation. | |
8 | ||
9 | * libmount mandates /etc/mtab not to be regular file, and | |
10 | systemd now enforces this condition at early boot. | |
11 | /etc/mtab has been deprecated and warned about for a very | |
12 | long time, so systems running systemd should already have | |
13 | stopped having this file around as anything else than a | |
14 | symlink to /proc/self/mounts. | |
15 | ||
16 | * Support for the "pids" cgroup controller has been added. It | |
17 | allows accounting the number of tasks in a cgroup and | |
18 | enforcing limits on it. This adds two new setting | |
19 | TasksAccounting= and TasksMax= to each unit, as well as a | |
20 | global option DefaultTasksAccounting=. | |
21 | ||
22 | * Support for the "net_cls" cgroup controller has been added. | |
23 | It allows assigning a net class ID to each task in the | |
24 | cgroup, which can then be used in firewall rules and traffic | |
25 | shaping configurations. Note that the kernel netfilter net | |
26 | class code does not currently work reliably for ingress | |
27 | packets on unestablished sockets. | |
28 | ||
29 | This adds a new config directive called NetClass= to CGroup | |
30 | enabled units. Allowed values are positive numbers for fixed | |
31 | assignments and "auto" for picking a free value | |
32 | automatically. | |
33 | ||
34 | * 'systemctl is-system-running' now returns 'offline' if the | |
35 | system is not booted with systemd. This command can now be | |
36 | used as a substitute for 'systemd-notify --booted'. | |
37 | ||
38 | * Watchdog timeouts have been increased to 3 minutes for all | |
39 | in-tree service files. Apparently, disk IO issues are more | |
40 | frequent than we hoped, and user reported >1 minute waiting | |
41 | for disk IO. | |
42 | ||
43 | * 'machine-id-commit' functionality has been merged into | |
44 | 'machine-id-setup --commit'. The separate binary has been | |
45 | removed. | |
46 | ||
47 | * The WorkingDirectory= directive in unit files may now be set | |
48 | to the special value '~'. In this case, the working | |
49 | directory is set to the home directory of the user | |
50 | configured in User=. | |
51 | ||
52 | * "machinectl shell" will now open the shell in the home | |
53 | directory of the selected user by default. | |
54 | ||
55 | * A new systemd.crash_reboot=1 kernel command line option has | |
56 | been added that triggers a reboot after crashing. This can | |
57 | also be set through CrashReboot= in systemd.conf. | |
58 | ||
59 | * The CrashChVT= configuration file setting is renamed to | |
60 | CrashChangeVT=, following our usual logic of not | |
61 | abbreviating unnecessarily. The old directive is still | |
62 | supported for compat reasons. Also, this directive now takes | |
63 | an integer value between 1 and 63, or a boolean value. The | |
64 | formerly supported '-1' value for disabling stays around for | |
65 | compat reasons. | |
66 | ||
67 | * The PrivateTmp=, PrivateDevices=, PrivateNetwork=, | |
68 | NoNewPrivileges=, TTYPath=, WorkingDirectory= and | |
69 | RootDirectory= properties can now be set for transient | |
70 | units. | |
71 | ||
72 | * The systemd-analyze tool gained a new "set-log-target" verb | |
73 | to change the logging target the system manager logs to | |
74 | dynamically during runtime. This is similar to how | |
75 | "systemd-analyze set-log-level" already changes the log | |
76 | level. | |
77 | ||
78 | * In nspawn /sys is now mounted as tmpfs, with only a selected | |
79 | set of subdirectories mounted in from the real sysfs. This | |
80 | enhances security slightly, and is useful for ensuring user | |
81 | namespaces work correctly. | |
82 | ||
83 | * Support for USB FunctionFS activation has been added. This | |
84 | allows implementation of USB gadget services that are | |
85 | activated as soon as they are requested, so that they don't | |
86 | have to run continously, similar to classic socket | |
87 | activation. | |
88 | ||
89 | * The "systemctl exit" command now optionally takes an | |
90 | additional parameter that sets the exit code to return from | |
91 | the systemd manager when exiting. This is only relevant when | |
92 | running the systemd user instance, or when running the | |
93 | system instance in a container. | |
94 | ||
95 | * sd-bus gained the new API calls sd_bus_path_encode_many() | |
96 | and sd_bus_path_decode_many() that allow easy encoding and | |
97 | decoding of multiple identifier strings inside a D-Bus | |
98 | object path. Another new call sd_bus_default_flush_close() | |
99 | has been added to flush and close per-thread default | |
100 | connections. | |
101 | ||
102 | * systemd-cgtop gained support for a -M/--machine= switch to | |
103 | show the control groups within a certain container only. | |
104 | ||
105 | * "systemctl kill" gained support for an optional --fail | |
106 | switch. If specified the requested operation will fail of no | |
107 | processes have been killed, because the unit had no | |
108 | processes attached, or similar. | |
109 | ||
110 | * A new (still internal) libary API sd-ipv4acd has been added, | |
111 | that implements address conflict detection for IPv4. It's | |
112 | based on code from sd-ipv4ll, and will be useful for | |
113 | detecting DHCP address conflicts. | |
114 | ||
115 | * The RuntimeDirectory= setting now understands unit | |
116 | specifiers like %i or %f. | |
117 | ||
118 | * systemd-networkd gained support for: | |
119 | ||
120 | - Setting the IPv6 Router Advertisment settings via | |
121 | IPv6AcceptRouterAdvertisements= in .network files. | |
122 | ||
123 | - Configuring the HelloTimeSec=, MaxAgeSec= and | |
124 | ForwardDelaySec= bridge parameters in .netdev files. | |
125 | ||
126 | - Configuring PreferredSource= for static routes in | |
127 | .network files. | |
128 | ||
129 | * udev will now create /dev/disk/by-path links for ATA devices | |
130 | on kernels where that is supported. | |
131 | ||
132 | * When downloading tar or raw images using "machinectl | |
133 | pull-tar" or "machinectl pull-raw", a matching ".nspawn" | |
134 | file is now also downloaded, if it is available and stored | |
135 | next to the image file. | |
136 | ||
137 | * Units of type ".socket" gained a new boolean setting | |
138 | Writable= which is only useful in conjunction with | |
139 | ListenSpecial=. If true, enables opening the specified | |
140 | special file in O_RDWR mode rather than O_RDONLY mode. | |
141 | ||
142 | * systemd-rfkill has been reworked to become a singleton | |
143 | service that is activated through /dev/rfkill on each rfkill | |
144 | state change and saves the settings to disk. This way, | |
145 | systemd-rfkill is now compatible with devices that exist | |
146 | only intermittendly, and even restores state if the previous | |
147 | system shutdown was abrupt rather than clean. | |
148 | ||
149 | * File descriptors passed during socket activation may now be | |
150 | named. A new API sd_listen_fds_with_names() is added to | |
151 | access the names. The default names may be overriden, | |
152 | either in the .socket file using the FileDescriptorName= | |
153 | parameter, or by passing FDNAME= when storing the file | |
154 | descriptors using sd_notify(). | |
155 | ||
156 | * The journal daemon gained support for vacuuming old journal | |
157 | files controlled by the number of files that shall remain, | |
158 | in addition to the already existing control by size and by | |
159 | date. This is useful as journal interleaving performance | |
160 | degrades with too many seperate journal files, and allows | |
161 | putting an effective limit on them. The new setting defaults | |
162 | to 100, but this may be changed by setting SystemMaxFiles= | |
163 | and RuntimeMaxFiles= in journald.conf. Also, the | |
164 | "journalctl" tool gained the new --vacuum-files= switch to | |
165 | manually vacuum journal files to leave only the specified | |
166 | number of files in place. | |
167 | ||
168 | * Galician, Serbian, Turkish and Korean translations were added. | |
169 | ||

173 | ||
174 | CHANGES WITH 226: | |
175 | ||
176 | * The DHCP implementation of systemd-networkd gained a set of | |
177 | new features: | |
178 | ||
179 | - The DHCP server now supports emitting DNS and NTP | |
180 | information. It may be enabled and configured via | |
181 | EmitDNS=, DNS=, EmitNTP=, and NTP=. If transmission of DNS | |
182 | and NTP information is enabled, but no servers are | |
183 | configured, the corresponding uplink information (if there | |
184 | is any) is propagated. | |
185 | ||
186 | - Server and client now support transmission and reception | |
187 | of timezone information. It can be configured via the | |
188 | newly introduced network options UseTimezone=, | |
189 | EmitTimezone=, and Timezone=. Transmission of timezone | |
190 | information is enabled between host and containers by | |
191 | default now: the container will change its local timezone | |
192 | to what the host has set. | |
193 | ||
194 | - Lease timeouts can now be configured via | |
195 | MaxLeaseTimeSec= and DefaultLeaseTimeSec=. | |
196 | ||
197 | - The DHCP server improved on the stability of | |
198 | leases. Clients are more likely to get the same lease | |
199 | information back, even if the server loses state. | |
200 | ||
201 | - The DHCP server supports two new configuration options to | |
202 | control the lease address pool metrics, PoolOffset= and | |
203 | PoolSize=. | |
204 | ||
205 | * The encapsulation limit of tunnels in systemd-networkd may | |
206 | now be configured via 'EncapsulationLimit='. It allows | |
207 | modifying the maximum additional levels of encapsulation | |
208 | that are permitted to be prepended to a packet. | |
209 | ||
210 | * systemd now supports the concept of user buses replacing | |
211 | session buses, if used with dbus-1.10 (and enabled via dbus | |
212 | --enable-user-session). It previously only supported this on | |
213 | kdbus-enabled systems, and this release expands this to | |
214 | 'dbus-daemon' systems. | |
215 | ||
216 | * systemd-networkd now supports predictable interface names | |
217 | for virtio devices. | |
218 | ||
219 | * systemd now optionally supports the new Linux kernel | |
220 | "unified" control group hierarchy. If enabled via the kernel | |
221 | command-line option 'systemd.unified_cgroup_hierarchy=1', | |
222 | systemd will try to mount the unified cgroup hierarchy | |
223 | directly on /sys/fs/cgroup. If not enabled, or not | |
224 | available, systemd will fall back to the legacy cgroup | |
225 | hierarchy setup, as before. Host system and containers can | |
226 | mix and match legacy and unified hierarchies as they | |
227 | wish. nspawn understands the $UNIFIED_CROUP_HIERARCHY | |
228 | environment variable to individually select the hierarchy to | |
229 | use for executed containers. By default, nspawn will use the | |
230 | unified hierarchy for the containers if the host uses the | |
231 | unified hierarchy, and the legacy hierarchy otherwise. | |
232 | Please note that at this point the unified hierarchy is an | |
233 | experimental kernel feature and is likely to change in one | |
234 | of the next kernel releases. Therefore, it should not be | |
235 | enabled by default in downstream distributions yet. The | |
236 | minimum required kernel version for the unified hierarchy to | |
237 | work is 4.2. Note that when the unified hierarchy is used | |
238 | for the first time delegated access to controllers is | |
239 | safe. Because of this systemd-nspawn containers will get | |
240 | access to controllers now, as will systemd user | |
241 | sessions. This means containers and user sessions may now | |
242 | manage their own resources, partitioning up what the system | |
243 | grants them. | |
244 | ||
245 | * A new special scope unit "init.scope" has been introduced | |
246 | that encapsulates PID 1 of the system. It may be used to | |
247 | determine resource usage and enforce resource limits on PID | |
248 | 1 itself. PID 1 hence moved out of the root of the control | |
249 | group tree. | |
250 | ||
251 | * The cgtop tool gained support for filtering out kernel | |
252 | threads when counting tasks in a control group. Also, the | |
253 | count of processes is now recursively summed up by | |
254 | default. Two options -k and --recursive= have been added to | |
255 | revert to old behaviour. The tool has also been updated to | |
256 | work correctly in containers now. | |
257 | ||
258 | * systemd-nspawn's --bind= and --bind-ro= options have been | |
259 | extended to allow creation of non-recursive bind mounts. | |
260 | ||
261 | * libsystemd gained two new calls sd_pid_get_cgroup() and | |
262 | sd_peer_get_cgroup() which return the control group path of | |
263 | a process or peer of a connected AF_UNIX socket. This | |
264 | function call is particularly useful when implementing | |
265 | delegated subtrees support in the control group hierarchy. | |
266 | ||
267 | * The "sd-event" event loop API of libsystemd now supports | |
268 | correct dequeuing of real-time signals, without losing | |
269 | signal events. | |
270 | ||
271 | * When systemd requests a PolicyKit decision when managing | |
272 | units it will now add additional fields to the request, | |
273 | including unit name and desired operation. This enables more | |
274 | powerful PolicyKit policies, that make decisions depending | |
275 | on these parameters. | |
276 | ||
277 | * nspawn learnt support for .nspawn settings files, that may | |
278 | accompany the image files or directories of containers, and | |
279 | may contain additional settings for the container. This is | |
280 | an alternative to configuring container parameters via the | |
281 | nspawn command line. | |

293 | ||
294 | CHANGES WITH 225: | |
295 | ||
296 | * machinectl gained a new verb 'shell' which opens a fresh | |
297 | shell on the target container or the host. It is similar to | |
298 | the existing 'login' command of machinectl, but spawns the | |
299 | shell directly without prompting for username or | |
300 | password. The pseudo machine '.host' now refers to the local | |
301 | host and is used by default. Hence, 'machinectl shell' can | |
302 | be used as replacement for 'su -' which spawns a session as | |
303 | a fresh systemd unit in a way that is fully isolated from | |
304 | the originating session. | |
305 | ||
306 | * systemd-networkd learned to cope with private-zone DHCP | |
307 | options and allows other programs to query the values. | |
308 | ||
309 | * SELinux access control when enabling/disabling units is no | |
310 | longer enforced with this release. The previous | |
311 | implementation was incorrect, and a new corrected | |
312 | implementation is not yet available. As unit file operations | |
313 | are still protected via PolicyKit and D-Bus policy this is | |
314 | not a security problem. Yet, distributions which care about | |
315 | optimal SELinux support should probably not stabilize on | |
316 | this release. | |
317 | ||
318 | * sd-bus gained support for matches of type "arg0has=", that | |
319 | test for membership of strings in string arrays sent in bus | |
320 | messages. | |
321 | ||
322 | * systemd-resolved now dumps the contents of its DNS and LLMNR | |
323 | caches to the logs on reception of the SIGUSR1 signal. This | |
324 | is useful to debug DNS behaviour. | |
325 | ||
326 | * The coredumpctl tool gained a new --directory= option to | |
327 | operate on journal files in a specific directory. | |
328 | ||
329 | * "systemctl reboot" and related commands gained a new | |
330 | "--message=" option which may be used to set a free-text | |
331 | wall message when shutting down or rebooting the | |
332 | system. This message is also logged, which is useful for | |
333 | figuring out the reason for a reboot or shutdown a | |
334 | posteriori. | |
335 | ||
336 | * The "systemd-resolve-host" tool's -i switch now takes | |
337 | network interface numbers as alternative to interface names. | |
338 | ||
339 | * A new unit file setting for services has been introduced: | |
340 | UtmpMode= allows configuration of how precisely systemd | |
341 | handles utmp and wtmp entries for the service if this is | |
342 | enabled. This allows writing services that appear similar to | |
343 | user sessions in the output of the "w", "who", "last" and | |
344 | "lastlog" tools. | |
345 | ||
346 | * systemd-resolved will now locally synthesize DNS resource | |
347 | records for the "localhost" and "gateway" domains as well as | |
348 | the local hostname. This should ensure that clients querying | |
349 | RRs via resolved will get similar results as those going via | |
350 | NSS, if nss-myhostname is enabled. | |

372 | * systemd-networkd now supports Group Policy for vxlan | |

382 | CHANGES WITH 223: | |
383 | ||
384 | * The python-systemd code has been removed from the systemd repository. | |
385 | A new repository has been created which accommodates the code from | |
386 | now on, and we kindly ask distributions to create a separate package | |
387 | for this: https://github.com/systemd/python-systemd | |
388 | ||
389 | * The systemd daemon will now reload its main configuration | |
390 | (/etc/systemd/system.conf) on daemon-reload. | |
391 | ||
392 | * sd-dhcp now exposes vendor specific extensions via | |
393 | sd_dhcp_lease_get_vendor_specific(). | |
394 | ||
395 | * systemd-networkd gained a number of new configuration options. | |
396 | ||
397 | - A new boolean configuration option for TAP devices called | |
398 | 'VNetHeader='. If set, the IFF_VNET_HDR flag is set for the | |
399 | device, thus allowing to send and receive GSO packets. | |
400 | ||
401 | - A new tunnel configuration option called 'CopyDSCP='. | |
402 | If enabled, the DSCP field of ip6 tunnels is copied into the | |
403 | decapsulated packet. | |
404 | ||
405 | - A set of boolean bridge configuration options were added. | |
406 | 'UseBPDU=', 'HairPin=', 'FastLeave=', 'AllowPortToBeRoot=', | |
407 | and 'UnicastFlood=' are now parsed by networkd and applied to the | |
408 | respective bridge link device via the respective IFLA_BRPORT_* | |
409 | netlink attribute. | |
410 | ||
411 | - A new string configuration option to override the hostname sent | |
412 | to a DHCP server, called 'Hostname='. If set and 'SendHostname=' | |
413 | is true, networkd will use the configured hostname instead of the | |
414 | system hostname when sending DHCP requests. | |
415 | ||
416 | - A new tunnel configuration option called 'IPv6FlowLabel='. If set, | |
417 | networkd will configure the IPv6 flow-label of the tunnel device | |
418 | according to RFC2460. | |
419 | ||
420 | - The 'macvtap' virtual network devices are now supported, similar to | |
421 | the already supported 'macvlan' devices. | |
422 | ||
423 | * systemd-resolved now implements RFC5452 to improve resilience against | |
424 | cache poisoning. Additionally, source port randomization is enabled | |
425 | by default to further protect against DNS spoofing attacks. | |
426 | ||
427 | * nss-mymachines now supports translating UIDs and GIDs of running | |
428 | containers with user-namespaces enabled. If a container 'foo' | |
429 | translates a host uid 'UID' to the container uid 'TUID', then | |
430 | nss-mymachines will also map uid 'UID' to/from username 'vu-foo-TUID' | |
431 | (with 'foo' and 'TUID' replaced accordingly). Similarly, groups are | |
432 | mapped as 'vg-foo-TGID'. | |

447 | CHANGES WITH 222: | |
448 | ||
449 | * udev does not longer support the WAIT_FOR_SYSFS= key in udev rules. | |
450 | There are no known issues with current sysfs, and udev does not need | |
451 | or should be used to work around such bugs. | |
452 | ||
453 | * udev does no longer enable USB HID power management. Several reports | |
454 | indicate, that some devices cannot handle that setting. | |
455 | ||
456 | * The udev accelerometer helper was removed. The functionality | |
457 | is now fully included in iio-sensor-proxy. But this means, | |
458 | older iio-sensor-proxy versions will no longer provide | |
459 | accelerometer/orientation data with this systemd version. | |
460 | Please upgrade iio-sensor-proxy to version 1.0. | |
461 | ||
462 | * networkd gained a new configuration option IPv6PrivacyExtensions= | |
463 | which enables IPv6 privacy extensions (RFC 4941, "Privacy Extensions | |
464 | for Stateless Address") on selected networks. | |
465 | ||
466 | * For the sake of fewer build-time dependencies and less code in the | |
467 | main repository, the python bindings are about to be removed in the | |
468 | next release. A new repository has been created which accommodates | |
469 | the code from now on, and we kindly ask distributions to create a | |
470 | separate package for this. The removal will take place in v223. | |

486 | ||
487 | CHANGES WITH 221: | |
488 | ||
489 | * The sd-bus.h and sd-event.h APIs have now been declared | |
490 | stable and have been added to the official interface of | |
491 | libsystemd.so. sd-bus implements an alternative D-Bus client | |
492 | library, that is relatively easy to use, very efficient and | |
493 | supports both classic D-Bus as well as kdbus as transport | |
494 | backend. sd-event is a generic event loop abstraction that | |
495 | is built around Linux epoll, but adds features such as event | |
496 | prioritization or efficient timer handling. Both APIs are good | |
497 | choices for C programs looking for a bus and/or event loop | |
498 | implementation that is minimal and does not have to be | |
499 | portable to other kernels. | |
500 | ||
501 | * kdbus support is no longer compile-time optional. It is now | |
502 | always built-in. However, it can still be disabled at | |
503 | runtime using the kdbus=0 kernel command line setting, and | |
504 | that setting may be changed to default to off, by specifying | |
505 | --disable-kdbus at build-time. Note though that the kernel | |
506 | command line setting has no effect if the kdbus.ko kernel | |
507 | module is not installed, in which case kdbus is (obviously) | |
508 | also disabled. We encourage all downstream distributions to | |
509 | begin testing kdbus by adding it to the kernel images in the | |
510 | development distributions, and leaving kdbus support in | |
511 | systemd enabled. | |
512 | ||
513 | * The minimal required util-linux version has been bumped to | |
514 | 2.26. | |
515 | ||
516 | * Support for chkconfig (--enable-chkconfig) was removed in | |
517 | favor of calling an abstraction tool | |
518 | /lib/systemd/systemd-sysv-install. This needs to be | |
519 | implemented for your distribution. See "SYSV INIT.D SCRIPTS" | |
520 | in README for details. | |
521 | ||
522 | * If there's a systemd unit and a SysV init script for the | |
523 | same service name, and the user executes "systemctl enable" | |
524 | for it (or a related call), then this will now enable both | |
525 | (or execute the related operation on both), not just the | |
526 | unit. | |
527 | ||
528 | * The libudev API documentation has been converted from gtkdoc | |
529 | into man pages. | |
530 | ||
531 | * gudev has been removed from the systemd tree, it is now an | |
532 | external project. | |
533 | ||
534 | * The systemd-cgtop tool learnt a new --raw switch to generate | |
535 | "raw" (machine parsable) output. | |
536 | ||
537 | * networkd's IPForwarding= .network file setting learnt the | |
538 | new setting "kernel", which ensures that networkd does not | |
539 | change the IP forwarding sysctl from the default kernel | |
540 | state. | |
541 | ||
542 | * The systemd-logind bus API now exposes a new boolean | |
543 | property "Docked" that reports whether logind considers the | |
544 | system "docked", i.e. connected to a docking station or not. | |

563 | -- Berlin, 2015-06-19 | |
564 | ||
565 | CHANGES WITH 220: | |
566 | ||
567 | * The gudev library has been extracted into a separate repository | |
568 | available at: https://git.gnome.org/browse/libgudev/ | |
569 | It is now managed as part of the Gnome project. Distributions | |
570 | are recommended to pass --disable-gudev to systemd and use | |
571 | gudev from the Gnome project instead. gudev is still included | |
572 | in systemd, for now. It will be removed soon, though. Please | |
573 | also see the announcement-thread on systemd-devel: | |
574 | http://lists.freedesktop.org/archives/systemd-devel/2015-May/032070.html | |
575 | ||
576 | * systemd now exposes a CPUUsageNSec= property for each | |
577 | service unit on the bus, that contains the overall consumed | |
578 | CPU time of a service (the sum of what each process of the | |
579 | service consumed). This value is only available if | |
580 | CPUAccounting= is turned on for a service, and is then shown | |
581 | in the "systemctl status" output. | |
582 | ||
583 | * Support for configuring alternative mappings of the old SysV | |
584 | runlevels to systemd targets has been removed. They are now | |
585 | hardcoded in a way that runlevels 2, 3, 4 all map to | |
586 | multi-user.target and 5 to graphical.target (which | |
587 | previously was already the default behaviour). | |
588 | ||
589 | * The auto-mounter logic gained support for mount point | |
590 | expiry, using a new TimeoutIdleSec= setting in .automount | |
591 | units. (Also available as x-systemd.idle-timeout= in /etc/fstab). | |
592 | ||
593 | * The EFI System Partition (ESP) as mounted to /boot by | |
594 | systemd-efi-boot-generator will now be unmounted | |
595 | automatically after 2 minutes of not being used. This should | |
596 | minimize the risk of ESP corruptions. | |
597 | ||
598 | * New /etc/fstab options x-systemd.requires= and | |
599 | x-systemd.requires-mounts-for= are now supported to express | |
600 | additional dependencies for mounts. This is useful for | |
601 | journalling file systems that support external journal | |
602 | devices or overlay file systems that require underlying file | |
603 | systems to be mounted. | |
604 | ||
605 | * systemd does not support direct live-upgrades (via systemctl | |
606 | daemon-reexec) from versions older than v44 anymore. As no | |
607 | distribution we are aware of shipped such old versions in a | |
608 | stable release this should not be problematic. | |
609 | ||
610 | * When systemd forks off a new per-connection service instance | |
611 | it will now set the $REMOTE_ADDR environment variable to the | |
612 | remote IP address, and $REMOTE_PORT environment variable to | |
613 | the remote IP port. This behaviour is similar to the | |
614 | corresponding environment variables defined by CGI. | |
615 | ||
616 | * systemd-networkd gained support for uplink failure | |
617 | detection. The BindCarrier= option allows binding interface | |
618 | configuration dynamically to the link sense of other | |
619 | interfaces. This is useful to achieve behaviour like in | |
620 | network switches. | |
621 | ||
622 | * systemd-networkd gained support for configuring the DHCP | |
623 | client identifier to use when requesting leases. | |
624 | ||
625 | * systemd-networkd now has a per-network UseNTP= option to | |
626 | configure whether NTP server information acquired via DHCP | |
627 | is passed on to services like systemd-timesyncd. | |
628 | ||
629 | * systemd-networkd gained support for vti6 tunnels. | |
630 | ||
631 | * Note that systemd-networkd manages the sysctl variable | |
632 | /proc/sys/net/ipv[46]/conf/*/forwarding for each interface | |
633 | it is configured for since v219. The variable controls IP | |
634 | forwarding, and is a per-interface alternative to the global | |
635 | /proc/sys/net/ipv[46]/ip_forward. This setting is | |
636 | configurable in the IPForward= option, which defaults to | |
637 | "no". This means if networkd is used for an interface it is | |
638 | no longer sufficient to set the global sysctl option to turn | |
639 | on IP forwarding! Instead, the .network file option | |
640 | IPForward= needs to be turned on! Note that the | |
641 | implementation of this behaviour was broken in v219 and has | |
642 | been fixed in v220. | |
643 | ||
644 | * Many bonding and vxlan options are now configurable in | |
645 | systemd-networkd. | |
646 | ||
647 | * systemd-nspawn gained a new --property= setting to set unit | |
648 | properties for the container scope. This is useful for | |
649 | setting resource parameters (e.g "CPUShares=500") on | |
650 | containers started from the command line. | |
651 | ||
652 | * systemd-nspawn gained a new --private-users= switch to make | |
653 | use of user namespacing available on recent Linux kernels. | |
654 | ||
655 | * systemd-nspawn may now be called as part of a shell pipeline | |
656 | in which case the pipes used for stdin and stdout are passed | |
657 | directly to the process invoked in the container, without | |
658 | indirection via a pseudo tty. | |
659 | ||
660 | * systemd-nspawn gained a new switch to control the UNIX | |
661 | signal to use when killing the init process of the container | |
662 | when shutting down. | |
663 | ||
664 | * systemd-nspawn gained a new --overlay= switch for mounting | |
665 | overlay file systems into the container using the new kernel | |
666 | overlayfs support. | |
667 | ||
668 | * When a container image is imported via systemd-importd and | |
669 | the host file system is not btrfs, a loopback block device | |
670 | file is created in /var/lib/machines.raw with a btrfs file | |
671 | system inside. It is then mounted to /var/lib/machines to | |
672 | enable btrfs features for container management. The loopback | |
673 | file and btrfs file system is grown as needed when container | |
674 | images are imported via systemd-importd. | |
675 | ||
676 | * systemd-machined/systemd-importd gained support for btrfs | |
677 | quota, to enforce container disk space limits on disk. This | |
678 | is exposed in "machinectl set-limit". | |
679 | ||
680 | * systemd-importd now can import containers from local .tar, | |
681 | .raw and .qcow2 images, and export them to .tar and .raw. It | |
682 | can also import dkr v2 images now from the network (on top | |
683 | of v1 as before). | |
684 | ||
685 | * systemd-importd gained support for verifying downloaded | |
686 | images with gpg2 (previously only gpg1 was supported). | |
687 | ||
688 | * systemd-machined, systemd-logind, systemd: most bus calls | |
689 | are now accessible to unprivileged processes via | |
690 | PolicyKit. Also, systemd-logind will now allow users to kill | |
691 | their own sessions without further privileges or | |
692 | authorization. | |
693 | ||
694 | * systemd-shutdownd has been removed. This service was | |
695 | previously responsible for implementing scheduled shutdowns | |
696 | as exposed in /usr/bin/shutdown's time parameter. This | |
697 | functionality has now been moved into systemd-logind and is | |
698 | accessible via a bus interface. | |
699 | ||
700 | * "systemctl reboot" gained a new switch --firmware-setup that | |
701 | can be used to reboot into the EFI firmware setup, if that | |
702 | is available. systemd-logind now exposes an API on the bus | |
703 | to trigger such reboots, in case graphical desktop UIs want | |
704 | to cover this functionality. | |
705 | ||
706 | * "systemctl enable", "systemctl disable" and "systemctl mask" | |
707 | now support a new "--now" switch. If specified the units | |
708 | that are enabled will also be started, and the ones | |
709 | disabled/masked also stopped. | |
710 | ||
711 | * The Gummiboot EFI boot loader tool has been merged into | |
712 | systemd, and renamed to "systemd-boot". The bootctl tool has been | |
713 | updated to support systemd-boot. | |
714 | ||
715 | * An EFI kernel stub has been added that may be used to create | |
716 | kernel EFI binaries that contain not only the actual kernel, | |
717 | but also an initrd, boot splash, command line and OS release | |
718 | information. This combined binary can then be signed as a | |
719 | single image, so that the firmware can verify it all in one | |
720 | step. systemd-boot has special support for EFI binaries created | |
721 | like this and can extract OS release information from them | |
722 | and show them in the boot menu. This functionality is useful | |
723 | to implement cryptographically verified boot schemes. | |
724 | ||
725 | * Optional support has been added to systemd-fsck to pass | |
726 | fsck's progress report to an AF_UNIX socket in the file | |
727 | system. | |
728 | ||
729 | * udev will no longer create device symlinks for all block | |
730 | devices by default. A blacklist for excluding special block | |
731 | devices from this logic has been turned into a whitelist | |
732 | that requires picking block devices explicitly that require | |
733 | device symlinks. | |
734 | ||
735 | * A new (currently still internal) API sd-device.h has been | |
736 | added to libsystemd. This modernized API is supposed to | |
737 | replace libudev eventually. In fact, already much of libudev | |
738 | is now just a wrapper around sd-device.h. | |
739 | ||
740 | * A new hwdb database for storing metadata about pointing | |
741 | stick devices has been added. | |
742 | ||
743 | * systemd-tmpfiles gained support for setting file attributes | |
744 | similar to the "chattr" tool with new 'h' and 'H' lines. | |
745 | ||
746 | * systemd-journald will no longer unconditionally set the | |
747 | btrfs NOCOW flag on new journal files. This is instead done | |
748 | with tmpfiles snippet using the new 'h' line type. This | |
749 | allows easy disabling of this logic, by masking the | |
750 | journal-nocow.conf tmpfiles file. | |
751 | ||
752 | * systemd-journald will now translate audit message types to | |
753 | human readable identifiers when writing them to the | |
754 | journal. This should improve readability of audit messages. | |
755 | ||
756 | * The LUKS logic gained support for the offset= and skip= | |
757 | options in /etc/crypttab, as previously implemented by | |
758 | Debian. | |
759 | ||
760 | * /usr/lib/os-release gained a new optional field VARIANT= for | |
761 | distributions that support multiple variants (such as a | |
762 | desktop edition, a server edition, ...) | |

792 | -- Berlin, 2015-05-22 | |
793 | ||
794 | CHANGES WITH 219: | |
795 | ||
796 | * Introduce a new API "sd-hwdb.h" for querying the hardware | |
797 | metadata database. With this minimal interface one can query | |
798 | and enumerate the udev hwdb, decoupled from the old libudev | |
799 | library. libudev's interface for this is now only a wrapper | |
800 | around sd-hwdb. A new tool systemd-hwdb has been added to | |
801 | interface with and update the database. | |
802 | ||
803 | * When any of systemd's tools copies files (for example due to | |
804 | tmpfiles' C lines) a btrfs reflink will attempted first, | |
805 | before bytewise copying is done. | |
806 | ||
807 | * systemd-nspawn gained a new --ephemeral switch. When | |
808 | specified a btrfs snapshot is taken of the container's root | |
809 | directory, and immediately removed when the container | |
810 | terminates again. Thus, a container can be started whose | |
811 | changes never alter the container's root directory, and are | |
812 | lost on container termination. This switch can also be used | |
813 | for starting a container off the root file system of the | |
814 | host without affecting the host OS. This switch is only | |
815 | available on btrfs file systems. | |
816 | ||
817 | * systemd-nspawn gained a new --template= switch. It takes the | |
818 | path to a container tree to use as template for the tree | |
819 | specified via --directory=, should that directory be | |
820 | missing. This allows instantiating containers dynamically, | |
821 | on first run. This switch is only available on btrfs file | |
822 | systems. | |
823 | ||
824 | * When a .mount unit refers to a mount point on which multiple | |
825 | mounts are stacked, and the .mount unit is stopped all of | |
826 | the stacked mount points will now be unmounted until no | |
827 | mount point remains. | |
828 | ||
829 | * systemd now has an explicit notion of supported and | |
830 | unsupported unit types. Jobs enqueued for unsupported unit | |
831 | types will now fail with an "unsupported" error code. More | |
832 | specifically .swap, .automount and .device units are not | |
833 | supported in containers, .busname units are not supported on | |
834 | non-kdbus systems. .swap and .automount are also not | |
835 | supported if their respective kernel compile time options | |
836 | are disabled. | |
837 | ||
838 | * machinectl gained support for two new "copy-from" and | |
839 | "copy-to" commands for copying files from a running | |
840 | container to the host or vice versa. | |
841 | ||
842 | * machinectl gained support for a new "bind" command to bind | |
843 | mount host directories into local containers. This is | |
844 | currently only supported for nspawn containers. | |
845 | ||
846 | * networkd gained support for configuring bridge forwarding | |
847 | database entries (fdb) from .network files. | |
848 | ||
849 | * A new tiny daemon "systemd-importd" has been added that can | |
850 | download container images in tar, raw, qcow2 or dkr formats, | |
851 | and make them available locally in /var/lib/machines, so | |
852 | that they can run as nspawn containers. The daemon can GPG | |
853 | verify the downloads (not supported for dkr, since it has no | |
854 | provisions for verifying downloads). It will transparently | |
855 | decompress bz2, xz, gzip compressed downloads if necessary, | |
856 | and restore sparse files on disk. The daemon uses privilege | |
857 | separation to ensure the actual download logic runs with | |
858 | fewer privileges than the daemon itself. machinectl has | |
859 | gained new commands "pull-tar", "pull-raw" and "pull-dkr" to | |
860 | make the functionality of importd available to the | |
861 | user. With this in place the Fedora and Ubuntu "Cloud" | |
862 | images can be downloaded and booted as containers unmodified | |
863 | (the Fedora images lack the appropriate GPG signature files | |
864 | currently, so they cannot be verified, but this will change | |
865 | soon, hopefully). Note that downloading images is currently | |
866 | only fully supported on btrfs. | |
867 | ||
868 | * machinectl is now able to list container images found in | |
869 | /var/lib/machines, along with some metadata about sizes of | |
870 | disk and similar. If the directory is located on btrfs and | |
871 | quota is enabled, this includes quota display. A new command | |
872 | "image-status" has been added that shows additional | |
873 | information about images. | |
874 | ||
875 | * machinectl is now able to clone container images | |
876 | efficiently, if the underlying file system (btrfs) supports | |
877 | it, with the new "machinectl list-images" command. It also | |
878 | gained commands for renaming and removing images, as well as | |
879 | marking them read-only or read-write (supported also on | |
880 | legacy file systems). | |
881 | ||
882 | * networkd gained support for collecting LLDP network | |
883 | announcements, from hardware that supports this. This is | |
884 | shown in networkctl output. | |
885 | ||
886 | * systemd-run gained support for a new -t (--pty) switch for | |
887 | invoking a binary on a pty whose input and output is | |
888 | connected to the invoking terminal. This allows executing | |
889 | processes as system services while interactively | |
890 | communicating with them via the terminal. Most interestingly | |
891 | this is supported across container boundaries. Invoking | |
892 | "systemd-run -t /bin/bash" is an alternative to running a | |
893 | full login session, the difference being that the former | |
894 | will not register a session, nor go through the PAM session | |
895 | setup. | |
896 | ||
897 | * tmpfiles gained support for a new "v" line type for creating | |
898 | btrfs subvolumes. If the underlying file system is a legacy | |
899 | file system, this automatically degrades to creating a | |
900 | normal directory. Among others /var/lib/machines is now | |
901 | created like this at boot, should it be missing. | |
902 | ||
903 | * The directory /var/lib/containers/ has been deprecated and | |
904 | been replaced by /var/lib/machines. The term "machines" has | |
905 | been used in the systemd context as generic term for both | |
906 | VMs and containers, and hence appears more appropriate for | |
907 | this, as the directory can also contain raw images bootable | |
908 | via qemu/kvm. | |
909 | ||
910 | * systemd-nspawn when invoked with -M but without --directory= | |
911 | or --image= is now capable of searching for the container | |
912 | root directory, subvolume or disk image automatically, in | |
913 | /var/lib/machines. systemd-nspawn@.service has been updated | |
914 | to make use of this, thus allowing it to be used for raw | |
915 | disk images, too. | |
916 | ||
917 | * A new machines.target unit has been introduced that is | |
918 | supposed to group all containers/VMs invoked as services on | |
919 | the system. systemd-nspawn@.service has been updated to | |
920 | integrate with that. | |
921 | ||
922 | * machinectl gained a new "start" command, for invoking a | |
923 | container as a service. "machinectl start foo" is mostly | |
924 | equivalent to "systemctl start systemd-nspawn@foo.service", | |
925 | but handles escaping in a nicer way. | |
926 | ||
927 | * systemd-nspawn will now mount most of the cgroupfs tree | |
928 | read-only into each container, with the exception of the | |
929 | container's own subtree in the name=systemd hierarchy. | |
930 | ||
931 | * journald now sets the special FS_NOCOW file flag for its | |
932 | journal files. This should improve performance on btrfs, by | |
933 | avoiding heavy fragmentation when journald's write-pattern | |
934 | is used on COW file systems. It degrades btrfs' data | |
935 | integrity guarantees for the files to the same levels as for | |
936 | ext3/ext4 however. This should be OK though as journald does | |
937 | its own data integrity checks and all its objects are | |
938 | checksummed on disk. Also, journald should handle btrfs disk | |
939 | full events a lot more gracefully now, by processing SIGBUS | |
940 | errors, and not relying on fallocate() anymore. | |
941 | ||
942 | * When journald detects that journal files it is writing to | |
943 | have been deleted it will immediately start new journal | |
944 | files. | |
945 | ||
946 | * systemd now provides a way to store file descriptors | |
947 | per-service in PID 1.This is useful for daemons to ensure | |
948 | that fds they require are not lost during a daemon | |
949 | restart. The fds are passed to the daemon on the next | |
950 | invocation in the same way socket activation fds are | |
951 | passed. This is now used by journald to ensure that the | |
952 | various sockets connected to all the system's stdout/stderr | |
953 | are not lost when journald is restarted. File descriptors | |
954 | may be stored in PID 1 via the sd_pid_notify_with_fds() API, | |
955 | an extension to sd_notify(). Note that a limit is enforced | |
956 | on the number of fds a service can store in PID 1, and it | |
957 | defaults to 0, so that no fds may be stored, unless this is | |
958 | explicitly turned on. | |
959 | ||
960 | * The default TERM variable to use for units connected to a | |
961 | terminal, when no other value is explicitly is set is now | |
962 | vt220 rather than vt102. This should be fairly safe still, | |
963 | but allows PgUp/PgDn work. | |
964 | ||
965 | * The /etc/crypttab option header= as known from Debian is now | |
966 | supported. | |
967 | ||
968 | * "loginctl user-status" and "loginctl session-status" will | |
969 | now show the last 10 lines of log messages of the | |
970 | user/session following the status output. Similar, | |
971 | "machinectl status" will show the last 10 log lines | |
972 | associated with a virtual machine or container | |
973 | service. (Note that this is usually not the log messages | |
974 | done in the VM/container itself, but simply what the | |
975 | container manager logs. For nspawn this includes all console | |
976 | output however.) | |
977 | ||
978 | * "loginctl session-status" without further argument will now | |
979 | show the status of the session of the caller. Similar, | |
980 | "lock-session", "unlock-session", "activate", | |
981 | "enable-linger", "disable-linger" may now be called without | |
982 | session/user parameter in which case they apply to the | |
983 | caller's session/user. | |
984 | ||
985 | * An X11 session scriptlet is now shipped that uploads | |
986 | $DISPLAY and $XAUTHORITY into the environment of the systemd | |
987 | --user daemon if a session begins. This should improve | |
988 | compatibility with X11 enabled applications run as systemd | |
989 | user services. | |
990 | ||
991 | * Generators are now subject to masking via /etc and /run, the | |
992 | same way as unit files. | |
993 | ||
994 | * networkd .network files gained support for configuring | |
995 | per-link IPv4/IPv6 packet forwarding as well as IPv4 | |
996 | masquerading. This is by default turned on for veth links to | |
997 | containers, as registered by systemd-nspawn. This means that | |
998 | nspawn containers run with --network-veth will now get | |
999 | automatic routed access to the host's networks without any | |
1000 | further configuration or setup, as long as networkd runs on | |
1001 | the host. | |
1002 | ||
1003 | * systemd-nspawn gained the --port= (-p) switch to expose TCP | |
1004 | or UDP posts of a container on the host. With this in place | |
1005 | it is possible to run containers with private veth links | |
1006 | (--network-veth), and have their functionality exposed on | |
1007 | the host as if their services were running directly on the | |
1008 | host. | |
1009 | ||
1010 | * systemd-nspawn's --network-veth switch now gained a short | |
1011 | version "-n", since with the changes above it is now truly | |
1012 | useful out-of-the-box. The systemd-nspawn@.service has been | |
1013 | updated to make use of it too by default. | |
1014 | ||
1015 | * systemd-nspawn will now maintain a per-image R/W lock, to | |
1016 | ensure that the same image is not started more than once | |
1017 | writable. (It's OK to run an image multiple times | |
1018 | simultaneously in read-only mode.) | |
1019 | ||
1020 | * systemd-nspawn's --image= option is now capable of | |
1021 | dissecting and booting MBR and GPT disk images that contain | |
1022 | only a single active Linux partition. Previously it | |
1023 | supported only GPT disk images with proper GPT type | |
1024 | IDs. This allows running cloud images from major | |
1025 | distributions directly with systemd-nspawn, without | |
1026 | modification. | |
1027 | ||
1028 | * In addition to collecting mouse dpi data in the udev | |
1029 | hardware database, there's now support for collecting angle | |
1030 | information for mouse scroll wheels. The database is | |
1031 | supposed to guarantee similar scrolling behavior on mice | |
1032 | that it knows about. There's also support for collecting | |
1033 | information about Touchpad types. | |
1034 | ||
1035 | * udev's input_id built-in will now also collect touch screen | |
1036 | dimension data and attach it to probed devices. | |
1037 | ||
1038 | * /etc/os-release gained support for a Distribution Privacy | |
1039 | Policy link field. | |
1040 | ||
1041 | * networkd gained support for creating "ipvlan", "gretap", | |
1042 | "ip6gre", "ip6gretap" and "ip6tnl" network devices. | |
1043 | ||
1044 | * systemd-tmpfiles gained support for "a" lines for setting | |
1045 | ACLs on files. | |
1046 | ||
1047 | * systemd-nspawn will now mount /tmp in the container to | |
1048 | tmpfs, automatically. | |
1049 | ||
1050 | * systemd now exposes the memory.usage_in_bytes cgroup | |
1051 | attribute and shows it for each service in the "systemctl | |
1052 | status" output, if available. | |
1053 | ||
1054 | * When the user presses Ctrl-Alt-Del more than 7x within 2s an | |
1055 | immediate reboot is triggered. This useful if shutdown is | |
1056 | hung and is unable to complete, to expedite the | |
1057 | operation. Note that this kind of reboot will still unmount | |
1058 | all file systems, and hence should not result in fsck being | |
1059 | run on next reboot. | |
1060 | ||
1061 | * A .device unit for an optical block device will now be | |
1062 | considered active only when a medium is in the drive. Also, | |
1063 | mount units are now bound to their backing devices thus | |
1064 | triggering automatic unmounting when devices become | |
1065 | unavailable. With this in place systemd will now | |
1066 | automatically unmount left-over mounts when a CD-ROM is | |
1067 | ejected or an USB stick is yanked from the system. | |
1068 | ||
1069 | * networkd-wait-online now has support for waiting for | |
1070 | specific interfaces only (with globbing), and for giving up | |
1071 | after a configurable timeout. | |
1072 | ||
1073 | * networkd now exits when idle. It will be automatically | |
1074 | restarted as soon as interfaces show up, are removed or | |
1075 | change state. networkd will stay around as long as there is | |
1076 | at least one DHCP state machine or similar around, that keep | |
1077 | it non-idle. | |
1078 | ||
1079 | * networkd may now configure IPv6 link-local addressing in | |
1080 | addition to IPv4 link-local addressing. | |
1081 | ||
1082 | * The IPv6 "token" for use in SLAAC may now be configured for | |
1083 | each .network interface in networkd. | |
1084 | ||
1085 | * Routes configured with networkd may now be assigned a scope | |
1086 | in .network files. | |
1087 | ||
1088 | * networkd's [Match] sections now support globbing and lists | |
1089 | of multiple space-separated matches per item. | |

1118 | CHANGES WITH 218: | |
1119 | ||
1120 | * When querying unit file enablement status (for example via | |
1121 | "systemctl is-enabled"), a new state "indirect" is now known | |
1122 | which indicates that a unit might not be enabled itself, but | |
1123 | another unit listed in its Also= setting might be. | |
1124 | ||
1125 | * Similar to the various existing ConditionXYZ= settings for | |
1126 | units there are now matching AssertXYZ= settings. While | |
1127 | failing conditions cause a unit to be skipped, but its job | |
1128 | to succeed, failing assertions declared like this will cause | |
1129 | a unit start operation and its job to fail. | |
1130 | ||
1131 | * hostnamed now knows a new chassis type "embedded". | |
1132 | ||
1133 | * systemctl gained a new "edit" command. When used on a unit | |
1134 | file this allows extending unit files with .d/ drop-in | |
1135 | configuration snippets or editing the full file (after | |
1136 | copying it from /usr/lib to /etc). This will invoke the | |
1137 | user's editor (as configured with $EDITOR), and reload the | |
1138 | modified configuration after editing. | |
1139 | ||
1140 | * "systemctl status" now shows the suggested enablement state | |
1141 | for a unit, as declared in the (usually vendor-supplied) | |
1142 | system preset files. | |
1143 | ||
1144 | * nss-myhostname will now resolve the single-label host name | |
1145 | "gateway" to the locally configured default IP routing | |
1146 | gateways, ordered by their metrics. This assigns a stable | |
1147 | name to the used gateways, regardless which ones are | |
1148 | currently configured. Note that the name will only be | |
1149 | resolved after all other name sources (if nss-myhostname is | |
1150 | configured properly) and should hence not negatively impact | |
1151 | systems that use the single-label host name "gateway" in | |
1152 | other contexts. | |
1153 | ||
1154 | * systemd-inhibit now allows filtering by mode when listing | |
1155 | inhibitors. | |
1156 | ||
1157 | * Scope and service units gained a new "Delegate" boolean | |
1158 | property, which when set allows processes running inside the | |
1159 | unit to further partition resources. This is primarily | |
1160 | useful for systemd user instances as well as container | |
1161 | managers. | |
1162 | ||
1163 | * journald will now pick up audit messages directly from | |
1164 | the kernel, and log them like any other log message. The | |
1165 | audit fields are split up and fully indexed. This means that | |
1166 | journalctl in many ways is now a (nicer!) alternative to | |
1167 | ausearch, the traditional audit client. Note that this | |
1168 | implements only a minimal audit client, if you want the | |
1169 | special audit modes like reboot-on-log-overflow, please use | |
1170 | the traditional auditd instead, which can be used in | |
1171 | parallel to journald. | |
1172 | ||
1173 | * The ConditionSecurity= unit file option now understands the | |
1174 | special string "audit" to check whether auditing is | |
1175 | available. | |
1176 | ||
1177 | * journalctl gained two new commands --vacuum-size= and | |
1178 | --vacuum-time= to delete old journal files until the | |
1179 | remaining ones take up no more the specified size on disk, | |
1180 | or are not older than the specified time. | |
1181 | ||
1182 | * A new, native PPPoE library has been added to sd-network, | |
1183 | systemd's library of light-weight networking protocols. This | |
1184 | library will be used in a future version of networkd to | |
1185 | enable PPPoE communication without an external pppd daemon. | |
1186 | ||
1187 | * The busctl tool now understands a new "capture" verb that | |
1188 | works similar to "monitor", but writes a packet capture | |
1189 | trace to STDOUT that can be redirected to a file which is | |
1190 | compatible with libcap's capture file format. This can then | |
1191 | be loaded in Wireshark and similar tools to inspect bus | |
1192 | communication. | |
1193 | ||
1194 | * The busctl tool now understands a new "tree" verb that shows | |
1195 | the object trees of a specific service on the bus, or of all | |
1196 | services. | |
1197 | ||
1198 | * The busctl tool now understands a new "introspect" verb that | |
1199 | shows all interfaces and members of objects on the bus, | |
1200 | including their signature and values. This is particularly | |
1201 | useful to get more information about bus objects shown by | |
1202 | the new "busctl tree" command. | |
1203 | ||
1204 | * The busctl tool now understands new verbs "call", | |
1205 | "set-property" and "get-property" for invoking bus method | |
1206 | calls, setting and getting bus object properties in a | |
1207 | friendly way. | |
1208 | ||
1209 | * busctl gained a new --augment-creds= argument that controls | |
1210 | whether the tool shall augment credential information it | |
1211 | gets from the bus with data from /proc, in a possibly | |
1212 | race-ful way. | |
1213 | ||
1214 | * nspawn's --link-journal= switch gained two new values | |
1215 | "try-guest" and "try-host" that work like "guest" and | |
1216 | "host", but do not fail if the host has no persistent | |
1217 | journalling enabled. -j is now equivalent to | |
1218 | --link-journal=try-guest. | |
1219 | ||
1220 | * macvlan network devices created by nspawn will now have | |
1221 | stable MAC addresses. | |
1222 | ||
1223 | * A new SmackProcessLabel= unit setting has been added, which | |
1224 | controls the SMACK security label processes forked off by | |
1225 | the respective unit shall use. | |
1226 | ||
1227 | * If compiled with --enable-xkbcommon, systemd-localed will | |
1228 | verify x11 keymap settings by compiling the given keymap. It | |
1229 | will spew out warnings if the compilation fails. This | |
1230 | requires libxkbcommon to be installed. | |
1231 | ||
1232 | * When a coredump is collected a larger number of metadata | |
1233 | fields is now collected and included in the journal records | |
1234 | created for it. More specifically control group membership, | |
1235 | environment variables, memory maps, working directory, | |
1236 | chroot directory, /proc/$PID/status, and a list of open file | |
1237 | descriptors is now stored in the log entry. | |
1238 | ||
1239 | * The udev hwdb now contains DPI information for mice. For | |
1240 | details see: | |
1241 | ||
1242 | http://who-t.blogspot.de/2014/12/building-a-dpi-database-for-mice.html | |
1243 | ||
1244 | * All systemd programs that read standalone configuration | |
1245 | files in /etc now also support a corresponding series of | |
1246 | .conf.d configuration directories in /etc/, /run/, | |
1247 | /usr/local/lib/, /usr/lib/, and (if configured with | |
1248 | --enable-split-usr) /lib/. In particular, the following | |
1249 | configuration files now have corresponding configuration | |
1250 | directories: system.conf user.conf, logind.conf, | |
1251 | journald.conf, sleep.conf, bootchart.conf, coredump.conf, | |
1252 | resolved.conf, timesyncd.conf, journal-remote.conf, and | |
1253 | journal-upload.conf. Note that distributions should use the | |
1254 | configuration directories in /usr/lib/; the directories in | |
1255 | /etc/ are reserved for the system administrator. | |
1256 | ||
1257 | * systemd-rfkill will no longer take the rfkill device name | |
1258 | into account when storing rfkill state on disk, as the name | |
1259 | might be dynamically assigned and not stable. Instead, the | |
1260 | ID_PATH udev variable combined with the rfkill type (wlan, | |
1261 | bluetooth, ...) is used. | |
1262 | ||
1263 | * A new service systemd-machine-id-commit.service has been | |
1264 | added. When used on systems where /etc is read-only during | |
1265 | boot, and /etc/machine-id is not initialized (but an empty | |
1266 | file), this service will copy the temporary machine ID | |
1267 | created as replacement into /etc after the system is fully | |
1268 | booted up. This is useful for systems that are freshly | |
1269 | installed with a non-initialized machine ID, but should get | |
1270 | a fixed machine ID for subsequent boots. | |
1271 | ||
1272 | * networkd's .netdev files now provide a large set of | |
1273 | configuration parameters for VXLAN devices. Similar, the | |
1274 | bridge port cost parameter is now configurable in .network | |
1275 | files. There's also new support for configuring IP source | |
1276 | routing. networkd .link files gained support for a new | |
1277 | OriginalName= match that is useful to match against the | |
1278 | original interface name the kernel assigned. .network files | |
1279 | may include MTU= and MACAddress= fields for altering the MTU | |
1280 | and MAC address while being connected to a specific network | |
1281 | interface. | |
1282 | ||
1283 | * The LUKS logic gained supported for configuring | |
1284 | UUID-specific key files. There's also new support for naming | |
1285 | LUKS device from the kernel command line, using the new | |
1286 | luks.name= argument. | |
1287 | ||
1288 | * Timer units may now be transiently created via the bus API | |
1289 | (this was previously already available for scope and service | |
1290 | units). In addition it is now possible to create multiple | |
1291 | transient units at the same time with a single bus call. The | |
1292 | "systemd-run" tool has been updated to make use of this for | |
1293 | running commands on a specified time, in at(1)-style. | |
1294 | ||
1295 | * tmpfiles gained support for "t" lines, for assigning | |
1296 | extended attributes to files. Among other uses this may be | |
1297 | used to assign SMACK labels to files. | |

1318 | -- Berlin, 2014-12-10 | |
1319 | ||
1320 | CHANGES WITH 217: | |
1321 | ||
1322 | * journalctl gained the new options -t/--identifier= to match | |
1323 | on the syslog identifier (aka "tag"), as well as --utc to | |
1324 | show log timestamps in the UTC timezone. journalctl now also | |
1325 | accepts -n/--lines=all to disable line capping in a pager. | |
1326 | ||
1327 | * journalctl gained a new switch, --flush, that synchronously | |
1328 | flushes logs from /run/log/journal to /var/log/journal if | |
1329 | persistent storage is enabled. systemd-journal-flush.service | |
1330 | now waits until the operation is complete. | |
1331 | ||
1332 | * Services can notify the manager before they start a reload | |
1333 | (by sending RELOADING=1) or shutdown (by sending | |
1334 | STOPPING=1). This allows the manager to track and show the | |
1335 | internal state of daemons and closes a race condition when | |
1336 | the process is still running but has closed its D-Bus | |
1337 | connection. | |
1338 | ||
1339 | * Services with Type=oneshot do not have to have any ExecStart | |
1340 | commands anymore. | |
1341 | ||
1342 | * User units are now loaded also from | |
1343 | $XDG_RUNTIME_DIR/systemd/user/. This is similar to the | |
1344 | /run/systemd/user directory that was already previously | |
1345 | supported, but is under the control of the user. | |
1346 | ||
1347 | * Job timeouts (i.e. time-outs on the time a job that is | |
1348 | queued stays in the run queue) can now optionally result in | |
1349 | immediate reboot or power-off actions (JobTimeoutAction= and | |
1350 | JobTimeoutRebootArgument=). This is useful on ".target" | |
1351 | units, to limit the maximum time a target remains | |
1352 | undispatched in the run queue, and to trigger an emergency | |
1353 | operation in such a case. This is now used by default to | |
1354 | turn off the system if boot-up (as defined by everything in | |
1355 | basic.target) hangs and does not complete for at least | |
1356 | 15min. Also, if power-off or reboot hang for at least 30min | |
1357 | an immediate power-off/reboot operation is triggered. This | |
1358 | functionality is particularly useful to increase reliability | |
1359 | on embedded devices, but also on laptops which might | |
1360 | accidentally get powered on when carried in a backpack and | |
1361 | whose boot stays stuck in a hard disk encryption passphrase | |
1362 | question. | |
1363 | ||
1364 | * systemd-logind can be configured to also handle lid switch | |
1365 | events even when the machine is docked or multiple displays | |
1366 | are attached (HandleLidSwitchDocked= option). | |
1367 | ||
1368 | * A helper binary and a service have been added which can be | |
1369 | used to resume from hibernation in the initramfs. A | |
1370 | generator will parse the resume= option on the kernel | |
1371 | command line to trigger resume. | |
1372 | ||
1373 | * A user console daemon systemd-consoled has been | |
1374 | added. Currently, it is a preview, and will so far open a | |
1375 | single terminal on each session of the user marked as | |
1376 | Desktop=systemd-console. | |
1377 | ||
1378 | * Route metrics can be specified for DHCP routes added by | |
1379 | systemd-networkd. | |
1380 | ||
1381 | * The SELinux context of socket-activated services can be set | |
1382 | from the information provided by the networking stack | |
1383 | (SELinuxContextFromNet= option). | |
1384 | ||
1385 | * Userspace firmware loading support has been removed and | |
1386 | the minimum supported kernel version is thus bumped to 3.7. | |
1387 | ||
1388 | * Timeout for udev workers has been increased from 1 to 3 | |
1389 | minutes, but a warning will be printed after 1 minute to | |
1390 | help diagnose kernel modules that take a long time to load. | |
1391 | ||
1392 | * Udev rules can now remove tags on devices with TAG-="foobar". | |
1393 | ||
1394 | * systemd's readahead implementation has been removed. In many | |
1395 | circumstances it didn't give expected benefits even for | |
1396 | rotational disk drives and was becoming less relevant in the | |
1397 | age of SSDs. As none of the developers has been using | |
1398 | rotating media anymore, and nobody stepped up to actively | |
1399 | maintain this component of systemd it has now been removed. | |
1400 | ||
1401 | * Swap units can use Options= to specify discard options. | |
1402 | Discard options specified for swaps in /etc/fstab are now | |
1403 | respected. | |
1404 | ||
1405 | * Docker containers are now detected as a separate type of | |
1406 | virtualization. | |
1407 | ||
1408 | * The Password Agent protocol gained support for queries where | |
1409 | the user input is shown, useful e.g. for user names. | |
1410 | systemd-ask-password gained a new --echo option to turn that | |
1411 | on. | |
1412 | ||
1413 | * The default sysctl.d/ snippets will now set: | |
1414 | ||
1415 | net.core.default_qdisc = fq_codel | |
1416 | ||
1417 | This selects Fair Queuing Controlled Delay as the default | |
1418 | queuing discipline for network interfaces. fq_codel helps | |
1419 | fight the network bufferbloat problem. It is believed to be | |
1420 | a good default with no tuning required for most workloads. | |
1421 | Downstream distributions may override this choice. On 10Gbit | |
1422 | servers that do not do forwarding, "fq" may perform better. | |
1423 | Systems without a good clocksource should use "pfifo_fast". | |
1424 | ||
1425 | * If kdbus is enabled during build a new option BusPolicy= is | |
1426 | available for service units, that allows locking all service | |
1427 | processes into a stricter bus policy, in order to limit | |
1428 | access to various bus services, or even hide most of them | |
1429 | from the service's view entirely. | |
1430 | ||
1431 | * networkctl will now show the .network and .link file | |
1432 | networkd has applied to a specific interface. | |
1433 | ||
1434 | * sd-login gained a new API call sd_session_get_desktop() to | |
1435 | query which desktop environment has been selected for a | |
1436 | session. | |
1437 | ||
1438 | * UNIX utmp support is now compile-time optional to support | |
1439 | legacy-free systems. | |
1440 | ||
1441 | * systemctl gained two new commands "add-wants" and | |
1442 | "add-requires" for pulling in units from specific targets | |
1443 | easily. | |
1444 | ||
1445 | * If the word "rescue" is specified on the kernel command line | |
1446 | the system will now boot into rescue mode (aka | |
1447 | rescue.target), which was previously available only by | |
1448 | specifying "1" or "systemd.unit=rescue.target" on the kernel | |
1449 | command line. This new kernel command line option nicely | |
1450 | mirrors the already existing "emergency" kernel command line | |
1451 | option. | |
1452 | ||
1453 | * New kernel command line options mount.usr=, mount.usrflags=, | |
1454 | mount.usrfstype= have been added that match root=, rootflags=, | |
1455 | rootfstype= but allow mounting a specific file system to | |
1456 | /usr. | |
1457 | ||
1458 | * The $NOTIFY_SOCKET is now also passed to control processes of | |
1459 | services, not only the main process. | |
1460 | ||
1461 | * This version reenables support for fsck's -l switch. This | |
1462 | means at least version v2.25 of util-linux is required for | |
1463 | operation, otherwise dead-locks on device nodes may | |
1464 | occur. Again: you need to update util-linux to at least | |
1465 | v2.25 when updating systemd to v217. | |
1466 | ||
1467 | * The "multi-seat-x" tool has been removed from systemd, as | |
1468 | its functionality has been integrated into X servers 1.16, | |
1469 | and the tool is hence redundant. It is recommended to update | |
1470 | display managers invoking this tool to simply invoke X | |
1471 | directly from now on, again. | |
1472 | ||
1473 | * Support for the new ALLOW_INTERACTIVE_AUTHORIZATION D-Bus | |
1474 | message flag has been added for all of systemd's PolicyKit | |
1475 | authenticated method calls has been added. In particular | |
1476 | this now allows optional interactive authorization via | |
1477 | PolicyKit for many of PID1's privileged operations such as | |
1478 | unit file enabling and disabling. | |
1479 | ||
1480 | * "udevadm hwdb --update" learnt a new switch "--usr" for | |
1481 | placing the rebuilt hardware database in /usr instead of | |
1482 | /etc. When used only hardware database entries stored in | |
1483 | /usr will be used, and any user database entries in /etc are | |
1484 | ignored. This functionality is useful for vendors to ship a | |
1485 | pre-built database on systems where local configuration is | |
1486 | unnecessary or unlikely. | |
1487 | ||
1488 | * Calendar time specifications in .timer units now also | |
1489 | understand the strings "semi-annually", "quarterly" and | |
1490 | "minutely" as shortcuts (in addition to the preexisting | |
1491 | "anually", "hourly", ...). | |
1492 | ||
1493 | * systemd-tmpfiles will now correctly create files in /dev | |
1494 | at boot which are marked for creation only at boot. It is | |
1495 | recommended to always create static device nodes with 'c!' | |
1496 | and 'b!', so that they are created only at boot and not | |
1497 | overwritten at runtime. | |
1498 | ||
1499 | * When the watchdog logic is used for a service (WatchdogSec=) | |
1500 | and the watchdog timeout is hit the service will now be | |
1501 | terminated with SIGABRT (instead of just SIGTERM), in order | |
1502 | to make sure a proper coredump and backtrace is | |
1503 | generated. This ensures that hanging services will result in | |
1504 | similar coredump/backtrace behaviour as services that hit a | |
1505 | segmentation fault. | |

1531 | ||
1532 | CHANGES WITH 216: | |
1533 | ||
1534 | * timedated no longer reads NTP implementation unit names from | |
1535 | /usr/lib/systemd/ntp-units.d/*.list. Alternative NTP | |
1536 | implementations should add a | |
1537 | ||
1538 | Conflicts=systemd-timesyncd.service | |
1539 | ||
1540 | to their unit files to take over and replace systemd's NTP | |
1541 | default functionality. | |
1542 | ||
1543 | * systemd-sysusers gained a new line type "r" for configuring | |
1544 | which UID/GID ranges to allocate system users/groups | |
1545 | from. Lines of type "u" may now add an additional column | |
1546 | that specifies the home directory for the system user to be | |
1547 | created. Also, systemd-sysusers may now optionally read user | |
1548 | information from STDIN instead of a file. This is useful for | |
1549 | invoking it from RPM preinst scriptlets that need to create | |
1550 | users before the first RPM file is installed since these | |
1551 | files might need to be owned by them. A new | |
1552 | %sysusers_create_inline RPM macro has been introduced to do | |
1553 | just that. systemd-sysusers now updates the shadow files as | |
1554 | well as the user/group databases, which should enhance | |
1555 | compatibility with certain tools like grpck. | |
1556 | ||
1557 | * A number of bus APIs of PID 1 now optionally consult | |
1558 | PolicyKit to permit access for otherwise unprivileged | |
1559 | clients under certain conditions. Note that this currently | |
1560 | doesn't support interactive authentication yet, but this is | |
1561 | expected to be added eventually, too. | |
1562 | ||
1563 | * /etc/machine-info now has new fields for configuring the | |
1564 | deployment environment of the machine, as well as the | |
1565 | location of the machine. hostnamectl has been updated with | |
1566 | new command to update these fields. | |
1567 | ||
1568 | * systemd-timesyncd has been updated to automatically acquire | |
1569 | NTP server information from systemd-networkd, which might | |
1570 | have been discovered via DHCP. | |
1571 | ||
1572 | * systemd-resolved now includes a caching DNS stub resolver | |
1573 | and a complete LLMNR name resolution implementation. A new | |
1574 | NSS module "nss-resolve" has been added which can be used | |
1575 | instead of glibc's own "nss-dns" to resolve hostnames via | |
1576 | systemd-resolved. Hostnames, addresses and arbitrary RRs may | |
1577 | be resolved via systemd-resolved D-Bus APIs. In contrast to | |
1578 | the glibc internal resolver systemd-resolved is aware of | |
1579 | multi-homed system, and keeps DNS server and caches separate | |
1580 | and per-interface. Queries are sent simultaneously on all | |
1581 | interfaces that have DNS servers configured, in order to | |
1582 | properly handle VPNs and local LANs which might resolve | |
1583 | separate sets of domain names. systemd-resolved may acquire | |
1584 | DNS server information from systemd-networkd automatically, | |
1585 | which in turn might have discovered them via DHCP. A tool | |
1586 | "systemd-resolve-host" has been added that may be used to | |
1587 | query the DNS logic in resolved. systemd-resolved implements | |
1588 | IDNA and automatically uses IDNA or UTF-8 encoding depending | |
1589 | on whether classic DNS or LLMNR is used as transport. In the | |
1590 | next releases we intend to add a DNSSEC and mDNS/DNS-SD | |
1591 | implementation to systemd-resolved. | |
1592 | ||
1593 | * A new NSS module nss-mymachines has been added, that | |
1594 | automatically resolves the names of all local registered | |
1595 | containers to their respective IP addresses. | |
1596 | ||
1597 | * A new client tool "networkctl" for systemd-networkd has been | |
1598 | added. It currently is entirely passive and will query | |
1599 | networking configuration from udev, rtnetlink and networkd, | |
1600 | and present it to the user in a very friendly | |
1601 | way. Eventually, we hope to extend it to become a full | |
1602 | control utility for networkd. | |
1603 | ||
1604 | * .socket units gained a new DeferAcceptSec= setting that | |
1605 | controls the kernels' TCP_DEFER_ACCEPT sockopt for | |
1606 | TCP. Similar, support for controlling TCP keep-alive | |
1607 | settings has been added (KeepAliveTimeSec=, | |
1608 | KeepAliveIntervalSec=, KeepAliveProbes=). Also, support for | |
1609 | turning off Nagle's algorithm on TCP has been added | |
1610 | (NoDelay=). | |
1611 | ||
1612 | * logind learned a new session type "web", for use in projects | |
1613 | like Cockpit which register web clients as PAM sessions. | |
1614 | ||
1615 | * timer units with at least one OnCalendar= setting will now | |
1616 | be started only after timer-sync.target has been | |
1617 | reached. This way they will not elapse before the system | |
1618 | clock has been corrected by a local NTP client or | |
1619 | similar. This is particular useful on RTC-less embedded | |
1620 | machines, that come up with an invalid system clock. | |
1621 | ||
1622 | * systemd-nspawn's --network-veth= switch should now result in | |
1623 | stable MAC addresses for both the outer and the inner side | |
1624 | of the link. | |
1625 | ||
1626 | * systemd-nspawn gained a new --volatile= switch for running | |
1627 | container instances with /etc or /var unpopulated. | |
1628 | ||
1629 | * The kdbus client code has been updated to use the new Linux | |
1630 | 3.17 memfd subsystem instead of the old kdbus-specific one. | |
1631 | ||
1632 | * systemd-networkd's DHCP client and server now support | |
1633 | FORCERENEW. There are also new configuration options to | |
1634 | configure the vendor client identifier and broadcast mode | |
1635 | for DHCP. | |
1636 | ||
1637 | * systemd will no longer inform the kernel about the current | |
1638 | timezone, as this is necessarily incorrect and racy as the | |
1639 | kernel has no understanding of DST and similar | |
1640 | concepts. This hence means FAT timestamps will be always | |
1641 | considered UTC, similar to what Android is already | |
1642 | doing. Also, when the RTC is configured to the local time | |
1643 | (rather than UTC) systemd will never synchronize back to it, | |
1644 | as this might confuse Windows at a later boot. | |
1645 | ||
1646 | * systemd-analyze gained a new command "verify" for offline | |
1647 | validation of unit files. | |
1648 | ||
1649 | * systemd-networkd gained support for a couple of additional | |
1650 | settings for bonding networking setups. Also, the metric for | |
1651 | statically configured routes may now be configured. For | |
1652 | network interfaces where this is appropriate the peer IP | |
1653 | address may now be configured. | |
1654 | ||
1655 | * systemd-networkd's DHCP client will no longer request | |
1656 | broadcasting by default, as this tripped up some networks. | |
1657 | For hardware where broadcast is required the feature should | |
1658 | be switched back on using RequestBroadcast=yes. | |
1659 | ||
1660 | * systemd-networkd will now set up IPv4LL addresses (when | |
1661 | enabled) even if DHCP is configured successfully. | |
1662 | ||
1663 | * udev will now default to respect network device names given | |
1664 | by the kernel when the kernel indicates that these are | |
1665 | predictable. This behavior can be tweaked by changing | |
1666 | NamePolicy= in the relevant .link file. | |
1667 | ||
1668 | * A new library systemd-terminal has been added that | |
1669 | implements full TTY stream parsing and rendering. This | |
1670 | library is supposed to be used later on for implementing a | |
1671 | full userspace VT subsystem, replacing the current kernel | |
1672 | implementation. | |
1673 | ||
1674 | * A new tool systemd-journal-upload has been added to push | |
1675 | journal data to a remote system running | |
1676 | systemd-journal-remote. | |
1677 | ||
1678 | * journald will no longer forward all local data to another | |
1679 | running syslog daemon. This change has been made because | |
1680 | rsyslog (which appears to be the most commonly used syslog | |
1681 | implementation these days) no longer makes use of this, and | |
1682 | instead pulls the data out of the journal on its own. Since | |
1683 | forwarding the messages to a non-existent syslog server is | |
1684 | more expensive than we assumed we have now turned this | |
1685 | off. If you run a syslog server that is not a recent rsyslog | |
1686 | version, you have to turn this option on again | |
1687 | (ForwardToSyslog= in journald.conf). | |
1688 | ||
1689 | * journald now optionally supports the LZ4 compressor for | |
1690 | larger journal fields. This compressor should perform much | |
1691 | better than XZ which was the previous default. | |
1692 | ||
1693 | * machinectl now shows the IP addresses of local containers, | |
1694 | if it knows them, plus the interface name of the container. | |
1695 | ||
1696 | * A new tool "systemd-escape" has been added that makes it | |
1697 | easy to escape strings to build unit names and similar. | |
1698 | ||
1699 | * sd_notify() messages may now include a new ERRNO= field | |
1700 | which is parsed and collected by systemd and shown among the | |
1701 | "systemctl status" output for a service. | |
1702 | ||
1703 | * A new component "systemd-firstboot" has been added that | |
1704 | queries the most basic systemd information (timezone, | |
1705 | hostname, root password) interactively on first | |
1706 | boot. Alternatively it may also be used to provision these | |
1707 | things offline on OS images installed into directories. | |
1708 | ||
1709 | * The default sysctl.d/ snippets will now set | |
1710 | ||
1711 | net.ipv4.conf.default.promote_secondaries=1 | |
1712 | ||
1713 | This has the benefit of no flushing secondary IP addresses | |
1714 | when primary addresses are removed. | |

1734 | CHANGES WITH 215: | |
1735 | ||
1736 | * A new tool systemd-sysusers has been added. This tool | |
1737 | creates system users and groups in /etc/passwd and | |
1738 | /etc/group, based on static declarative system user/group | |
1739 | definitions in /usr/lib/sysusers.d/. This is useful to | |
1740 | enable factory resets and volatile systems that boot up with | |
1741 | an empty /etc directory, and thus need system users and | |
1742 | groups created during early boot. systemd now also ships | |
1743 | with two default sysusers.d/ files for the most basic | |
1744 | users and groups systemd and the core operating system | |
1745 | require. | |
1746 | ||
1747 | * A new tmpfiles snippet has been added that rebuilds the | |
1748 | essential files in /etc on boot, should they be missing. | |
1749 | ||
1750 | * A directive for ensuring automatic clean-up of | |
1751 | /var/cache/man/ has been removed from the default | |
1752 | configuration. This line should now be shipped by the man | |
1753 | implementation. The necessary change has been made to the | |
1754 | man-db implementation. Note that you need to update your man | |
1755 | implementation to one that ships this line, otherwise no | |
1756 | automatic clean-up of /var/cache/man will take place. | |
1757 | ||
1758 | * A new condition ConditionNeedsUpdate= has been added that | |
1759 | may conditionalize services to only run when /etc or /var | |
1760 | are "older" than the vendor operating system resources in | |
1761 | /usr. This is useful for reconstructing or updating /etc | |
1762 | after an offline update of /usr or a factory reset, on the | |
1763 | next reboot. Services that want to run once after such an | |
1764 | update or reset should use this condition and order | |
1765 | themselves before the new systemd-update-done.service, which | |
1766 | will mark the two directories as fully updated. A number of | |
1767 | service files have been added making use of this, to rebuild | |
1768 | the udev hardware database, the journald message catalog and | |
1769 | dynamic loader cache (ldconfig). The systemd-sysusers tool | |
1770 | described above also makes use of this now. With this in | |
1771 | place it is now possible to start up a minimal operating | |
1772 | system with /etc empty cleanly. For more information on the | |
1773 | concepts involved see this recent blog story: | |
1774 | ||
1775 | http://0pointer.de/blog/projects/stateless.html | |
1776 | ||
1777 | * A new system group "input" has been introduced, and all | |
1778 | input device nodes get this group assigned. This is useful | |
1779 | for system-level software to get access to input devices. It | |
1780 | complements what is already done for "audio" and "video". | |
1781 | ||
1782 | * systemd-networkd learnt minimal DHCPv4 server support in | |
1783 | addition to the existing DHCPv4 client support. It also | |
1784 | learnt DHCPv6 client and IPv6 Router Solicitation client | |
1785 | support. The DHCPv4 client gained support for static routes | |
1786 | passed in from the server. Note that the [DHCPv4] section | |
1787 | known in older systemd-networkd versions has been renamed to | |
1788 | [DHCP] and is now also used by the DHCPv6 client. Existing | |
1789 | .network files using settings of this section should be | |
1790 | updated, though compatibility is maintained. Optionally, the | |
1791 | client hostname may now be sent to the DHCP server. | |
1792 | ||
1793 | * networkd gained support for vxlan virtual networks as well | |
1794 | as tun/tap and dummy devices. | |
1795 | ||
1796 | * networkd gained support for automatic allocation of address | |
1797 | ranges for interfaces from a system-wide pool of | |
1798 | addresses. This is useful for dynamically managing a large | |
1799 | number of interfaces with a single network configuration | |
1800 | file. In particular this is useful to easily assign | |
1801 | appropriate IP addresses to the veth links of a large number | |
1802 | of nspawn instances. | |
1803 | ||
1804 | * RPM macros for processing sysusers, sysctl and binfmt | |
1805 | drop-in snippets at package installation time have been | |
1806 | added. | |
1807 | ||
1808 | * The /etc/os-release file should now be placed in | |
1809 | /usr/lib/os-release. The old location is automatically | |
1810 | created as symlink. /usr/lib is the more appropriate | |
1811 | location of this file, since it shall actually describe the | |
1812 | vendor operating system shipped in /usr, and not the | |
1813 | configuration stored in /etc. | |
1814 | ||
1815 | * .mount units gained a new boolean SloppyOptions= setting | |
1816 | that maps to mount(8)'s -s option which enables permissive | |
1817 | parsing of unknown mount options. | |
1818 | ||
1819 | * tmpfiles learnt a new "L+" directive which creates a symlink | |
1820 | but (unlike "L") deletes a pre-existing file first, should | |
1821 | it already exist and not already be the correct | |
1822 | symlink. Similar, "b+", "c+" and "p+" directives have been | |
1823 | added as well, which create block and character devices, as | |
1824 | well as fifos in the filesystem, possibly removing any | |
1825 | pre-existing files of different types. | |
1826 | ||
1827 | * For tmpfiles' "L", "L+", "C" and "C+" directives the final | |
1828 | 'argument' field (which so far specified the source to | |
1829 | symlink/copy the files from) is now optional. If omitted the | |
1830 | same file os copied from /usr/share/factory/ suffixed by the | |
1831 | full destination path. This is useful for populating /etc | |
1832 | with essential files, by copying them from vendor defaults | |
1833 | shipped in /usr/share/factory/etc. | |
1834 | ||
1835 | * A new command "systemctl preset-all" has been added that | |
1836 | applies the service preset settings to all installed unit | |
1837 | files. A new switch --preset-mode= has been added that | |
1838 | controls whether only enable or only disable operations | |
1839 | shall be executed. | |
1840 | ||
1841 | * A new command "systemctl is-system-running" has been added | |
1842 | that allows checking the overall state of the system, for | |
1843 | example whether it is fully up and running. | |
1844 | ||
1845 | * When the system boots up with an empty /etc, the equivalent | |
1846 | to "systemctl preset-all" is executed during early boot, to | |
1847 | make sure all default services are enabled after a factory | |
1848 | reset. | |
1849 | ||
1850 | * systemd now contains a minimal preset file that enables the | |
1851 | most basic services systemd ships by default. | |
1852 | ||
1853 | * Unit files' [Install] section gained a new DefaultInstance= | |
1854 | field for defining the default instance to create if a | |
1855 | template unit is enabled with no instance specified. | |
1856 | ||
1857 | * A new passive target cryptsetup-pre.target has been added | |
1858 | that may be used by services that need to make they run and | |
1859 | finish before the first LUKS cryptographic device is set up. | |
1860 | ||
1861 | * The /dev/loop-control and /dev/btrfs-control device nodes | |
1862 | are now owned by the "disk" group by default, opening up | |
1863 | access to this group. | |
1864 | ||
1865 | * systemd-coredump will now automatically generate a | |
1866 | stack trace of all core dumps taking place on the system, | |
1867 | based on elfutils' libdw library. This stack trace is logged | |
1868 | to the journal. | |
1869 | ||
1870 | * systemd-coredump may now optionally store coredumps directly | |
1871 | on disk (in /var/lib/systemd/coredump, possibly compressed), | |
1872 | instead of storing them unconditionally in the journal. This | |
1873 | mode is the new default. A new configuration file | |
1874 | /etc/systemd/coredump.conf has been added to configure this | |
1875 | and other parameters of systemd-coredump. | |
1876 | ||
1877 | * coredumpctl gained a new "info" verb to show details about a | |
1878 | specific coredump. A new switch "-1" has also been added | |
1879 | that makes sure to only show information about the most | |
1880 | recent entry instead of all entries. Also, as the tool is | |
1881 | generally useful now the "systemd-" prefix of the binary | |
1882 | name has been removed. Distributions that want to maintain | |
1883 | compatibility with the old name should add a symlink from | |
1884 | the old name to the new name. | |
1885 | ||
1886 | * journald's SplitMode= now defaults to "uid". This makes sure | |
1887 | that unprivileged users can access their own coredumps with | |
1888 | coredumpctl without restrictions. | |
1889 | ||
1890 | * New kernel command line options "systemd.wants=" (for | |
1891 | pulling an additional unit during boot), "systemd.mask=" | |
1892 | (for masking a specific unit for the boot), and | |
1893 | "systemd.debug-shell" (for enabling the debug shell on tty9) | |
1894 | have been added. This is implemented in the new generator | |
1895 | "systemd-debug-generator". | |
1896 | ||
1897 | * systemd-nspawn will now by default filter a couple of | |
1898 | syscalls for containers, among them those required for | |
1899 | kernel module loading, direct x86 IO port access, swap | |
1900 | management, and kexec. Most importantly though | |
1901 | open_by_handle_at() is now prohibited for containers, | |
1902 | closing a hole similar to a recently discussed vulnerability | |
1903 | in docker regarding access to files on file hierarchies the | |
1904 | container should normally not have access to. Note that for | |
1905 | nspawn we generally make no security claims anyway (and | |
1906 | this is explicitly documented in the man page), so this is | |
1907 | just a fix for one of the most obvious problems. | |
1908 | ||
1909 | * A new man page file-hierarchy(7) has been added that | |
1910 | contains a minimized, modernized version of the file system | |
1911 | layout systemd expects, similar in style to the FHS | |
1912 | specification or hier(5). A new tool systemd-path(1) has | |
1913 | been added to query many of these paths for the local | |
1914 | machine and user. | |
1915 | ||
1916 | * Automatic time-based clean-up of $XDG_RUNTIME_DIR is no | |
1917 | longer done. Since the directory now has a per-user size | |
1918 | limit, and is cleaned on logout this appears unnecessary, | |
1919 | in particular since this now brings the lifecycle of this | |
1920 | directory closer in line with how IPC objects are handled. | |
1921 | ||
1922 | * systemd.pc now exports a number of additional directories, | |
1923 | including $libdir (which is useful to identify the library | |
1924 | path for the primary architecture of the system), and a | |
1925 | couple of drop-in directories. | |
1926 | ||
1927 | * udev's predictable network interface names now use the dev_port | |
1928 | sysfs attribute, introduced in linux 3.15 instead of dev_id to | |
1929 | distinguish between ports of the same PCI function. dev_id should | |
1930 | only be used for ports using the same HW address, hence the need | |
1931 | for dev_port. | |
1932 | ||
1933 | * machined has been updated to export the OS version of a | |
1934 | container (read from /etc/os-release and | |
1935 | /usr/lib/os-release) on the bus. This is now shown in | |
1936 | "machinectl status" for a machine. | |
1937 | ||
1938 | * A new service setting RestartForceExitStatus= has been | |
1939 | added. If configured to a set of exit signals or process | |
1940 | return values, the service will be restarted when the main | |
1941 | daemon process exits with any of them, regardless of the | |
1942 | Restart= setting. | |
1943 | ||
1944 | * systemctl's -H switch for connecting to remote systemd | |
1945 | machines has been extended so that it may be used to | |
1946 | directly connect to a specific container on the | |
1947 | host. "systemctl -H root@foobar:waldi" will now connect as | |
1948 | user "root" to host "foobar", and then proceed directly to | |
1949 | the container named "waldi". Note that currently you have to | |
1950 | authenticate as user "root" for this to work, as entering | |
1951 | containers is a privileged operation. | |

1966 | -- Berlin, 2014-07-03 | |
1967 | ||
1968 | CHANGES WITH 214: | |
1969 | ||
1970 | * As an experimental feature, udev now tries to lock the | |
1971 | disk device node (flock(LOCK_SH|LOCK_NB)) while it | |
1972 | executes events for the disk or any of its partitions. | |
1973 | Applications like partitioning programs can lock the | |
1974 | disk device node (flock(LOCK_EX)) and claim temporary | |
1975 | device ownership that way; udev will entirely skip all event | |
1976 | handling for this disk and its partitions. If the disk | |
1977 | was opened for writing, the close will trigger a partition | |
1978 | table rescan in udev's "watch" facility, and if needed | |
1979 | synthesize "change" events for the disk and all its partitions. | |
1980 | This is now unconditionally enabled, and if it turns out to | |
1981 | cause major problems, we might turn it on only for specific | |
1982 | devices, or might need to disable it entirely. Device Mapper | |
1983 | devices are excluded from this logic. | |
1984 | ||
1985 | * We temporarily dropped the "-l" switch for fsck invocations, | |
1986 | since they collide with the flock() logic above. util-linux | |
1987 | upstream has been changed already to avoid this conflict, | |
1988 | and we will readd "-l" as soon as util-linux with this | |
1989 | change has been released. | |
1990 | ||
1991 | * The dependency on libattr has been removed. Since a long | |
1992 | time, the extended attribute calls have moved to glibc, and | |
1993 | libattr is thus unnecessary. | |
1994 | ||
1995 | * Virtualization detection works without priviliges now. This | |
1996 | means the systemd-detect-virt binary no longer requires | |
1997 | CAP_SYS_PTRACE file capabilities, and our daemons can run | |
1998 | with fewer privileges. | |
1999 | ||
2000 | * systemd-networkd now runs under its own "systemd-network" | |
2001 | user. It retains the CAP_NET_ADMIN, CAP_NET_BIND_SERVICE, | |
2002 | CAP_NET_BROADCAST, CAP_NET_RAW capabilities though, but | |
2003 | loses the ability to write to files owned by root this way. | |
2004 | ||
2005 | * Similar, systemd-resolved now runs under its own | |
2006 | "systemd-resolve" user with no capabilities remaining. | |
2007 | ||
2008 | * Similar, systemd-bus-proxyd now runs under its own | |
2009 | "systemd-bus-proxy" user with only CAP_IPC_OWNER remaining. | |
2010 | ||
2011 | * systemd-networkd gained support for setting up "veth" | |
2012 | virtual ethernet devices for container connectivity, as well | |
2013 | as GRE and VTI tunnels. | |
2014 | ||
2015 | * systemd-networkd will no longer automatically attempt to | |
2016 | manually load kernel modules necessary for certain tunnel | |
2017 | transports. Instead, it is assumed the kernel loads them | |
2018 | automatically when required. This only works correctly on | |
2019 | very new kernels. On older kernels, please consider adding | |
2020 | the kernel modules to /etc/modules-load.d/ as a work-around. | |
2021 | ||
2022 | * The resolv.conf file systemd-resolved generates has been | |
2023 | moved to /run/systemd/resolve/. If you have a symlink from | |
2024 | /etc/resolv.conf, it might be necessary to correct it. | |
2025 | ||
2026 | * Two new service settings, ProtectHome= and ProtectSystem=, | |
2027 | have been added. When enabled, they will make the user data | |
2028 | (such as /home) inaccessible or read-only and the system | |
2029 | (such as /usr) read-only, for specific services. This allows | |
2030 | very light-weight per-service sandboxing to avoid | |
2031 | modifications of user data or system files from | |
2032 | services. These two new switches have been enabled for all | |
2033 | of systemd's long-running services, where appropriate. | |
2034 | ||
2035 | * Socket units gained new SocketUser= and SocketGroup= | |
2036 | settings to set the owner user and group of AF_UNIX sockets | |
2037 | and FIFOs in the file system. | |
2038 | ||
2039 | * Socket units gained a new RemoveOnStop= setting. If enabled, | |
2040 | all FIFOS and sockets in the file system will be removed | |
2041 | when the specific socket unit is stopped. | |
2042 | ||
2043 | * Socket units gained a new Symlinks= setting. It takes a list | |
2044 | of symlinks to create to file system sockets or FIFOs | |
2045 | created by the specific Unix sockets. This is useful to | |
2046 | manage symlinks to socket nodes with the same life-cycle as | |
2047 | the socket itself. | |
2048 | ||
2049 | * The /dev/log socket and /dev/initctl FIFO have been moved to | |
2050 | /run, and have been replaced by symlinks. This allows | |
2051 | connecting to these facilities even if PrivateDevices=yes is | |
2052 | used for a service (which makes /dev/log itself unavailable, | |
2053 | but /run is left). This also has the benefit of ensuring | |
2054 | that /dev only contains device nodes, directories and | |
2055 | symlinks, and nothing else. | |
2056 | ||
2057 | * sd-daemon gained two new calls sd_pid_notify() and | |
2058 | sd_pid_notifyf(). They are similar to sd_notify() and | |
2059 | sd_notifyf(), but allow overriding of the source PID of | |
2060 | notification messages if permissions permit this. This is | |
2061 | useful to send notify messages on behalf of a different | |
2062 | process (for example, the parent process). The | |
2063 | systemd-notify tool has been updated to make use of this | |
2064 | when sending messages (so that notification messages now | |
2065 | originate from the shell script invoking systemd-notify and | |
2066 | not the systemd-notify process itself. This should minimize | |
2067 | a race where systemd fails to associate notification | |
2068 | messages to services when the originating process already | |
2069 | vanished. | |
2070 | ||
2071 | * A new "on-abnormal" setting for Restart= has been added. If | |
2072 | set, it will result in automatic restarts on all "abnormal" | |
2073 | reasons for a process to exit, which includes unclean | |
2074 | signals, core dumps, timeouts and watchdog timeouts, but | |
2075 | does not include clean and unclean exit codes or clean | |
2076 | signals. Restart=on-abnormal is an alternative for | |
2077 | Restart=on-failure for services that shall be able to | |
2078 | terminate and avoid restarts on certain errors, by | |
2079 | indicating so with an unclean exit code. Restart=on-failure | |
2080 | or Restart=on-abnormal is now the recommended setting for | |
2081 | all long-running services. | |
2082 | ||
2083 | * If the InaccessibleDirectories= service setting points to a | |
2084 | mount point (or if there are any submounts contained within | |
2085 | it), it is now attempted to completely unmount it, to make | |
2086 | the file systems truly unavailable for the respective | |
2087 | service. | |
2088 | ||
2089 | * The ReadOnlyDirectories= service setting and | |
2090 | systemd-nspawn's --read-only parameter are now recursively | |
2091 | applied to all submounts, too. | |
2092 | ||
2093 | * Mount units may now be created transiently via the bus APIs. | |
2094 | ||
2095 | * The support for SysV and LSB init scripts has been removed | |
2096 | from the systemd daemon itself. Instead, it is now | |
2097 | implemented as a generator that creates native systemd units | |
2098 | from these scripts when needed. This enables us to remove a | |
2099 | substantial amount of legacy code from PID 1, following the | |
2100 | fact that many distributions only ship a very small number | |
2101 | of LSB/SysV init scripts nowadays. | |
2102 | ||
2103 | * Privileged Xen (dom0) domains are not considered | |
2104 | virtualization anymore by the virtualization detection | |
2105 | logic. After all, they generally have unrestricted access to | |
2106 | the hardware and usually are used to manage the unprivileged | |
2107 | (domU) domains. | |
2108 | ||
2109 | * systemd-tmpfiles gained a new "C" line type, for copying | |
2110 | files or entire directories. | |
2111 | ||
2112 | * systemd-tmpfiles "m" lines are now fully equivalent to "z" | |
2113 | lines. So far, they have been non-globbing versions of the | |
2114 | latter, and have thus been redundant. In future, it is | |
2115 | recommended to only use "z". "m" has hence been removed | |
2116 | from the documentation, even though it stays supported. | |
2117 | ||
2118 | * A tmpfiles snippet to recreate the most basic structure in | |
2119 | /var has been added. This is enough to create the /var/run → | |
2120 | /run symlink and create a couple of structural | |
2121 | directories. This allows systems to boot up with an empty or | |
2122 | volatile /var. Of course, while with this change, the core OS | |
2123 | now is capable with dealing with a volatile /var, not all | |
2124 | user services are ready for it. However, we hope that sooner | |
2125 | or later, many service daemons will be changed upstream so | |
2126 | that they are able to automatically create their necessary | |
2127 | directories in /var at boot, should they be missing. This is | |
2128 | the first step to allow state-less systems that only require | |
2129 | the vendor image for /usr to boot. | |
2130 | ||
2131 | * systemd-nspawn has gained a new --tmpfs= switch to mount an | |
2132 | empty tmpfs instance to a specific directory. This is | |
2133 | particularly useful for making use of the automatic | |
2134 | reconstruction of /var (see above), by passing --tmpfs=/var. | |
2135 | ||
2136 | * Access modes specified in tmpfiles snippets may now be | |
2137 | prefixed with "~", which indicates that they shall be masked | |
2138 | by whether the existing file or directory is currently | |
2139 | writable, readable or executable at all. Also, if specified, | |
2140 | the sgid/suid/sticky bits will be masked for all | |
2141 | non-directories. | |
2142 | ||
2143 | * A new passive target unit "network-pre.target" has been | |
2144 | added which is useful for services that shall run before any | |
2145 | network is configured, for example firewall scripts. | |
2146 | ||
2147 | * The "floppy" group that previously owned the /dev/fd* | |
2148 | devices is no longer used. The "disk" group is now used | |
2149 | instead. Distributions should probably deprecate usage of | |
2150 | this group. | |

2160 | -- Berlin, 2014-06-11 | |
2161 | ||
2162 | CHANGES WITH 213: | |
2163 | ||
2164 | * A new "systemd-timesyncd" daemon has been added for | |
2165 | synchronizing the system clock across the network. It | |
2166 | implements an SNTP client. In contrast to NTP | |
2167 | implementations such as chrony or the NTP reference server, | |
2168 | this only implements a client side, and does not bother with | |
2169 | the full NTP complexity, focusing only on querying time from | |
2170 | one remote server and synchronizing the local clock to | |
2171 | it. Unless you intend to serve NTP to networked clients or | |
2172 | want to connect to local hardware clocks, this simple NTP | |
2173 | client should be more than appropriate for most | |
2174 | installations. The daemon runs with minimal privileges, and | |
2175 | has been hooked up with networkd to only operate when | |
2176 | network connectivity is available. The daemon saves the | |
2177 | current clock to disk every time a new NTP sync has been | |
2178 | acquired, and uses this to possibly correct the system clock | |
2179 | early at bootup, in order to accommodate for systems that | |
2180 | lack an RTC such as the Raspberry Pi and embedded devices, | |
2181 | and to make sure that time monotonically progresses on these | |
2182 | systems, even if it is not always correct. To make use of | |
2183 | this daemon, a new system user and group "systemd-timesync" | |
2184 | needs to be created on installation of systemd. | |
2185 | ||
2186 | * The queue "seqnum" interface of libudev has been disabled, as | |
2187 | it was generally incompatible with device namespacing as | |
2188 | sequence numbers of devices go "missing" if the devices are | |
2189 | part of a different namespace. | |
2190 | ||
2191 | * "systemctl list-timers" and "systemctl list-sockets" gained | |
2192 | a --recursive switch for showing units of these types also | |
2193 | for all local containers, similar in style to the already | |
2194 | supported --recursive switch for "systemctl list-units". | |
2195 | ||
2196 | * A new RebootArgument= setting has been added for service | |
2197 | units, which may be used to specify a kernel reboot argument | |
2198 | to use when triggering reboots with StartLimitAction=. | |
2199 | ||
2200 | * A new FailureAction= setting has been added for service | |
2201 | units which may be used to specify an operation to trigger | |
2202 | when a service fails. This works similarly to | |
2203 | StartLimitAction=, but unlike it, controls what is done | |
2204 | immediately rather than only after several attempts to | |
2205 | restart the service in question. | |
2206 | ||
2207 | * hostnamed got updated to also expose the kernel name, | |
2208 | release, and version on the bus. This is useful for | |
2209 | executing commands like hostnamectl with the -H switch. | |
2210 | systemd-analyze makes use of this to properly display | |
2211 | details when running non-locally. | |
2212 | ||
2213 | * The bootchart tool can now show cgroup information in the | |
2214 | graphs it generates. | |
2215 | ||
2216 | * The CFS CPU quota cgroup attribute is now exposed for | |
2217 | services. The new CPUQuota= switch has been added for this | |
2218 | which takes a percentage value. Setting this will have the | |
2219 | result that a service may never get more CPU time than the | |
2220 | specified percentage, even if the machine is otherwise idle. | |
2221 | ||
2222 | * systemd-networkd learned IPIP and SIT tunnel support. | |
2223 | ||
2224 | * LSB init scripts exposing a dependency on $network will now | |
2225 | get a dependency on network-online.target rather than simply | |
2226 | network.target. This should bring LSB handling closer to | |
2227 | what it was on SysV systems. | |
2228 | ||
2229 | * A new fsck.repair= kernel option has been added to control | |
2230 | how fsck shall deal with unclean file systems at boot. | |
2231 | ||
2232 | * The (.ini) configuration file parser will now silently | |
2233 | ignore sections whose name begins with "X-". This may be | |
2234 | used to maintain application-specific extension sections in unit | |
2235 | files. | |
2236 | ||
2237 | * machined gained a new API to query the IP addresses of | |
2238 | registered containers. "machinectl status" has been updated | |
2239 | to show these addresses in its output. | |
2240 | ||
2241 | * A new call sd_uid_get_display() has been added to the | |
2242 | sd-login APIs for querying the "primary" session of a | |
2243 | user. The "primary" session of the user is elected from the | |
2244 | user's sessions and generally a graphical session is | |
2245 | preferred over a text one. | |
2246 | ||
2247 | * A minimal systemd-resolved daemon has been added. It | |
2248 | currently simply acts as a companion to systemd-networkd and | |
2249 | manages resolv.conf based on per-interface DNS | |
2250 | configuration, possibly supplied via DHCP. In the long run | |
2251 | we hope to extend this into a local DNSSEC enabled DNS and | |
2252 | mDNS cache. | |
2253 | ||
2254 | * The systemd-networkd-wait-online tool is now enabled by | |
2255 | default. It will delay network-online.target until a network | |
2256 | connection has been configured. The tool primarily integrates | |
2257 | with networkd, but will also make a best effort to make sense | |
2258 | of network configuration performed in some other way. | |
2259 | ||
2260 | * Two new service options StartupCPUShares= and | |
2261 | StartupBlockIOWeight= have been added that work similarly to | |
2262 | CPUShares= and BlockIOWeight= however only apply during | |
2263 | system startup. This is useful to prioritize certain services | |
2264 | differently during bootup than during normal runtime. | |
2265 | ||
2266 | * hostnamed has been changed to prefer the statically | |
2267 | configured hostname in /etc/hostname (unless set to | |
2268 | 'localhost' or empty) over any dynamic one supplied by | |
2269 | dhcp. With this change, the rules for picking the hostname | |
2270 | match more closely the rules of other configuration settings | |
2271 | where the local administrator's configuration in /etc always | |
2272 | overrides any other settings. | |

2292 | -- Beijing, 2014-05-28 | |
2293 | ||
2294 | CHANGES WITH 212: | |
2295 | ||
2296 | * When restoring the screen brightness at boot, stay away from | |
2297 | the darkest setting or from the lowest 5% of the available | |
2298 | range, depending on which is the larger value of both. This | |
2299 | should effectively protect the user from rebooting into a | |
2300 | black screen, should the brightness have been set to minimum | |
2301 | by accident. | |
2302 | ||
2303 | * sd-login gained a new sd_machine_get_class() call to | |
2304 | determine the class ("vm" or "container") of a machine | |
2305 | registered with machined. | |
2306 | ||
2307 | * sd-login gained new calls | |
2308 | sd_peer_get_{session,owner_uid,unit,user_unit,slice,machine_name}(), | |
2309 | to query the identity of the peer of a local AF_UNIX | |
2310 | connection. They operate similarly to their sd_pid_get_xyz() | |
2311 | counterparts. | |
2312 | ||
2313 | * PID 1 will now maintain a system-wide system state engine | |
2314 | with the states "starting", "running", "degraded", | |
2315 | "maintenance", "stopping". These states are bound to system | |
2316 | startup, normal runtime, runtime with at least one failed | |
2317 | service, rescue/emergency mode and system shutdown. This | |
2318 | state is shown in the "systemctl status" output when no unit | |
2319 | name is passed. It is useful to determine system state, in | |
2320 | particularly when doing so for many systems or containers at | |
2321 | once. | |
2322 | ||
2323 | * A new command "list-machines" has been added to "systemctl" | |
2324 | that lists all local OS containers and shows their system | |
2325 | state (see above), if systemd runs inside of them. | |
2326 | ||
2327 | * systemctl gained a new "-r" switch to recursively enumerate | |
2328 | units on all local containers, when used with the | |
2329 | "list-unit" command (which is the default one that is | |
2330 | executed when no parameters are specified). | |
2331 | ||
2332 | * The GPT automatic partition discovery logic will now honour | |
2333 | two GPT partition flags: one may be set on a partition to | |
2334 | cause it to be mounted read-only, and the other may be set | |
2335 | on a partition to ignore it during automatic discovery. | |
2336 | ||
2337 | * Two new GPT type UUIDs have been added for automatic root | |
2338 | partition discovery, for 32-bit and 64-bit ARM. This is not | |
2339 | particularly useful for discovering the root directory on | |
2340 | these architectures during bare-metal boots (since UEFI is | |
2341 | not common there), but still very useful to allow booting of | |
2342 | ARM disk images in nspawn with the -i option. | |
2343 | ||
2344 | * MAC addresses of interfaces created with nspawn's | |
2345 | --network-interface= switch will now be generated from the | |
2346 | machine name, and thus be stable between multiple invocations | |
2347 | of the container. | |
2348 | ||
2349 | * logind will now automatically remove all IPC objects owned | |
2350 | by a user if she or he fully logs out. This makes sure that | |
2351 | users who are logged out cannot continue to consume IPC | |
2352 | resources. This covers SysV memory, semaphores and message | |
2353 | queues as well as POSIX shared memory and message | |
2354 | queues. Traditionally, SysV and POSIX IPC had no life-cycle | |
2355 | limits. With this functionality, that is corrected. This may | |
2356 | be turned off by using the RemoveIPC= switch of logind.conf. | |
2357 | ||
2358 | * The systemd-machine-id-setup and tmpfiles tools gained a | |
2359 | --root= switch to operate on a specific root directory, | |
2360 | instead of /. | |
2361 | ||
2362 | * journald can now forward logged messages to the TTYs of all | |
2363 | logged in users ("wall"). This is the default for all | |
2364 | emergency messages now. | |
2365 | ||
2366 | * A new tool systemd-journal-remote has been added to stream | |
2367 | journal log messages across the network. | |
2368 | ||
2369 | * /sys/fs/cgroup/ is now mounted read-only after all cgroup | |
2370 | controller trees are mounted into it. Note that the | |
2371 | directories mounted beneath it are not read-only. This is a | |
2372 | security measure and is particularly useful because glibc | |
2373 | actually includes a search logic to pick any tmpfs it can | |
2374 | find to implement shm_open() if /dev/shm is not available | |
2375 | (which it might very well be in namespaced setups). | |
2376 | ||
2377 | * machinectl gained a new "poweroff" command to cleanly power | |
2378 | down a local OS container. | |
2379 | ||
2380 | * The PrivateDevices= unit file setting will now also drop the | |
2381 | CAP_MKNOD capability from the capability bound set, and | |
2382 | imply DevicePolicy=closed. | |
2383 | ||
2384 | * PrivateDevices=, PrivateNetwork= and PrivateTmp= is now used | |
2385 | comprehensively on all long-running systemd services where | |
2386 | this is appropriate. | |
2387 | ||
2388 | * systemd-udevd will now run in a disassociated mount | |
2389 | namespace. To mount directories from udev rules, make sure to | |
2390 | pull in mount units via SYSTEMD_WANTS properties. | |
2391 | ||
2392 | * The kdbus support gained support for uploading policy into | |
2393 | the kernel. sd-bus gained support for creating "monitoring" | |
2394 | connections that can eavesdrop into all bus communication | |
2395 | for debugging purposes. | |
2396 | ||
2397 | * Timestamps may now be specified in seconds since the UNIX | |
2398 | epoch Jan 1st, 1970 by specifying "@" followed by the value | |
2399 | in seconds. | |
2400 | ||
2401 | * Native tcpwrap support in systemd has been removed. tcpwrap | |
2402 | is old code, not really maintained anymore and has serious | |
2403 | shortcomings, and better options such as firewalls | |
2404 | exist. For setups that require tcpwrap usage, please | |
2405 | consider invoking your socket-activated service via tcpd, | |
2406 | like on traditional inetd. | |
2407 | ||
2408 | * A new system.conf configuration option | |
2409 | DefaultTimerAccuracySec= has been added that controls the | |
2410 | default AccuracySec= setting of .timer units. | |
2411 | ||
2412 | * Timer units gained a new WakeSystem= switch. If enabled, | |
2413 | timers configured this way will cause the system to resume | |
2414 | from system suspend (if the system supports that, which most | |
2415 | do these days). | |
2416 | ||
2417 | * Timer units gained a new Persistent= switch. If enabled, | |
2418 | timers configured this way will save to disk when they have | |
2419 | been last triggered. This information is then used on next | |
2420 | reboot to possible execute overdue timer events, that | |
2421 | could not take place because the system was powered off. | |
2422 | This enables simple anacron-like behaviour for timer units. | |
2423 | ||
2424 | * systemctl's "list-timers" will now also list the time a | |
2425 | timer unit was last triggered in addition to the next time | |
2426 | it will be triggered. | |
2427 | ||
2428 | * systemd-networkd will now assign predictable IPv4LL | |
2429 | addresses to its local interfaces. | |

2441 | -- Berlin, 2014-03-25 | |
2442 | ||
2443 | CHANGES WITH 211: | |
2444 | ||
2445 | * A new unit file setting RestrictAddressFamilies= has been | |
2446 | added to restrict which socket address families unit | |
2447 | processes gain access to. This takes address family names | |
2448 | like "AF_INET" or "AF_UNIX", and is useful to minimize the | |
2449 | attack surface of services via exotic protocol stacks. This | |
2450 | is built on seccomp system call filters. | |
2451 | ||
2452 | * Two new unit file settings RuntimeDirectory= and | |
2453 | RuntimeDirectoryMode= have been added that may be used to | |
2454 | manage a per-daemon runtime directories below /run. This is | |
2455 | an alternative for setting up directory permissions with | |
2456 | tmpfiles snippets, and has the advantage that the runtime | |
2457 | directory's lifetime is bound to the daemon runtime and that | |
2458 | the daemon starts up with an empty directory each time. This | |
2459 | is particularly useful when writing services that drop | |
2460 | privileges using the User= or Group= setting. | |
2461 | ||
2462 | * The DeviceAllow= unit setting now supports globbing for | |
2463 | matching against device group names. | |
2464 | ||
2465 | * The systemd configuration file system.conf gained new | |
2466 | settings DefaultCPUAccounting=, DefaultBlockIOAccounting=, | |
2467 | DefaultMemoryAccounting= to globally turn on/off accounting | |
2468 | for specific resources (cgroups) for all units. These | |
2469 | settings may still be overridden individually in each unit | |
2470 | though. | |
2471 | ||
2472 | * systemd-gpt-auto-generator is now able to discover /srv and | |
2473 | root partitions in addition to /home and swap partitions. It | |
2474 | also supports LUKS-encrypted partitions now. With this in | |
2475 | place, automatic discovery of partitions to mount following | |
2476 | the Discoverable Partitions Specification | |
2477 | (http://www.freedesktop.org/wiki/Specifications/DiscoverablePartitionsSpec) | |
2478 | is now a lot more complete. This allows booting without | |
2479 | /etc/fstab and without root= on the kernel command line on | |
2480 | systems prepared appropriately. | |
2481 | ||
2482 | * systemd-nspawn gained a new --image= switch which allows | |
2483 | booting up disk images and Linux installations on any block | |
2484 | device that follow the Discoverable Partitions Specification | |
2485 | (see above). This means that installations made with | |
2486 | appropriately updated installers may now be started and | |
2487 | deployed using container managers, completely | |
2488 | unmodified. (We hope that libvirt-lxc will add support for | |
2489 | this feature soon, too.) | |
2490 | ||
2491 | * systemd-nspawn gained a new --network-macvlan= setting to | |
2492 | set up a private macvlan interface for the | |
2493 | container. Similarly, systemd-networkd gained a new | |
2494 | Kind=macvlan setting in .netdev files. | |
2495 | ||
2496 | * systemd-networkd now supports configuring local addresses | |
2497 | using IPv4LL. | |
2498 | ||
2499 | * A new tool systemd-network-wait-online has been added to | |
2500 | synchronously wait for network connectivity using | |
2501 | systemd-networkd. | |
2502 | ||
2503 | * The sd-bus.h bus API gained a new sd_bus_track object for | |
2504 | tracking the life-cycle of bus peers. Note that sd-bus.h is | |
2505 | still not a public API though (unless you specify | |
2506 | --enable-kdbus on the configure command line, which however | |
2507 | voids your warranty and you get no API stability guarantee). | |
2508 | ||
2509 | * The $XDG_RUNTIME_DIR runtime directories for each user are | |
2510 | now individual tmpfs instances, which has the benefit of | |
2511 | introducing separate pools for each user, with individual | |
2512 | size limits, and thus making sure that unprivileged clients | |
2513 | can no longer negatively impact the system or other users by | |
2514 | filling up their $XDG_RUNTIME_DIR. A new logind.conf setting | |
2515 | RuntimeDirectorySize= has been introduced that allows | |
2516 | controlling the default size limit for all users. It | |
2517 | defaults to 10% of the available physical memory. This is no | |
2518 | replacement for quotas on tmpfs though (which the kernel | |
2519 | still does not support), as /dev/shm and /tmp are still | |
2520 | shared resources used by both the system and unprivileged | |
2521 | users. | |
2522 | ||
2523 | * logind will now automatically turn off automatic suspending | |
2524 | on laptop lid close when more than one display is | |
2525 | connected. This was previously expected to be implemented | |
2526 | individually in desktop environments (such as GNOME), | |
2527 | however has been added to logind now, in order to fix a | |
2528 | boot-time race where a desktop environment might not have | |
2529 | been started yet and thus not been able to take an inhibitor | |
2530 | lock at the time where logind already suspends the system | |
2531 | due to a closed lid. | |
2532 | ||
2533 | * logind will now wait at least 30s after each system | |
2534 | suspend/resume cycle, and 3min after system boot before | |
2535 | suspending the system due to a closed laptop lid. This | |
2536 | should give USB docking stations and similar enough time to | |
2537 | be probed and configured after system resume and boot in | |
2538 | order to then act as suspend blocker. | |
2539 | ||
2540 | * systemd-run gained a new --property= setting which allows | |
2541 | initialization of resource control properties (and others) | |
2542 | for the created scope or service unit. Example: "systemd-run | |
2543 | --property=BlockIOWeight=10 updatedb" may be used to run | |
2544 | updatedb at a low block IO scheduling weight. | |
2545 | ||
2546 | * systemd-run's --uid=, --gid=, --setenv=, --setenv= switches | |
2547 | now also work in --scope mode. | |
2548 | ||
2549 | * When systemd is compiled with kdbus support, basic support | |
2550 | for enforced policies is now in place. (Note that enabling | |
2551 | kdbus still voids your warranty and no API compatibility | |
2552 | promises are made.) | |

2567 | CHANGES WITH 210: | |
2568 | ||
2569 | * systemd will now relabel /dev after loading the SMACK policy | |
2570 | according to SMACK rules. | |
2571 | ||
2572 | * A new unit file option AppArmorProfile= has been added to | |
2573 | set the AppArmor profile for the processes of a unit. | |
2574 | ||
2575 | * A new condition check ConditionArchitecture= has been added | |
2576 | to conditionalize units based on the system architecture, as | |
2577 | reported by uname()'s "machine" field. | |
2578 | ||
2579 | * systemd-networkd now supports matching on the system | |
2580 | virtualization, architecture, kernel command line, host name | |
2581 | and machine ID. | |
2582 | ||
2583 | * logind is now a lot more aggressive when suspending the | |
2584 | machine due to a closed laptop lid. Instead of acting only | |
2585 | on the lid close action, it will continuously watch the lid | |
2586 | status and act on it. This is useful for laptops where the | |
2587 | power button is on the outside of the chassis so that it can | |
2588 | be reached without opening the lid (such as the Lenovo | |
2589 | Yoga). On those machines, logind will now immediately | |
2590 | re-suspend the machine if the power button has been | |
2591 | accidentally pressed while the laptop was suspended and in a | |
2592 | backpack or similar. | |
2593 | ||
2594 | * logind will now watch SW_DOCK switches and inhibit reaction | |
2595 | to the lid switch if it is pressed. This means that logind | |
2596 | will not suspend the machine anymore if the lid is closed | |
2597 | and the system is docked, if the laptop supports SW_DOCK | |
2598 | notifications via the input layer. Note that ACPI docking | |
2599 | stations do not generate this currently. Also note that this | |
2600 | logic is usually not fully sufficient and Desktop | |
2601 | Environments should take a lid switch inhibitor lock when an | |
2602 | external display is connected, as systemd will not watch | |
2603 | this on its own. | |
2604 | ||
2605 | * nspawn will now make use of the devices cgroup controller by | |
2606 | default, and only permit creation of and access to the usual | |
2607 | API device nodes like /dev/null or /dev/random, as well as | |
2608 | access to (but not creation of) the pty devices. | |
2609 | ||
2610 | * We will now ship a default .network file for | |
2611 | systemd-networkd that automatically configures DHCP for | |
2612 | network interfaces created by nspawn's --network-veth or | |
2613 | --network-bridge= switches. | |
2614 | ||
2615 | * systemd will now understand the usual M, K, G, T suffixes | |
2616 | according to SI conventions (i.e. to the base 1000) when | |
2617 | referring to throughput and hardware metrics. It will stay | |
2618 | with IEC conventions (i.e. to the base 1024) for software | |
2619 | metrics, according to what is customary according to | |
2620 | Wikipedia. We explicitly document which base applies for | |
2621 | each configuration option. | |
2622 | ||
2623 | * The DeviceAllow= setting in unit files now supports a syntax | |
2624 | to whitelist an entire group of devices node majors at once, | |
2625 | based on the /proc/devices listing. For example, with the | |
2626 | string "char-pts", it is now possible to whitelist all | |
2627 | current and future pseudo-TTYs at once. | |
2628 | ||
2629 | * sd-event learned a new "post" event source. Event sources of | |
2630 | this type are triggered by the dispatching of any event | |
2631 | source of a type that is not "post". This is useful for | |
2632 | implementing clean-up and check event sources that are | |
2633 | triggered by other work being done in the program. | |
2634 | ||
2635 | * systemd-networkd is no longer statically enabled, but uses | |
2636 | the usual [Install] sections so that it can be | |
2637 | enabled/disabled using systemctl. It still is enabled by | |
2638 | default however. | |
2639 | ||
2640 | * When creating a veth interface pair with systemd-nspawn, the | |
2641 | host side will now be prefixed with "vb-" if | |
2642 | --network-bridge= is used, and with "ve-" if --network-veth | |
2643 | is used. This way, it is easy to distinguish these cases on | |
2644 | the host, for example to apply different configuration to | |
2645 | them with systemd-networkd. | |
2646 | ||
2647 | * The compatibility libraries for libsystemd-journal.so, | |
2648 | libsystem-id128.so, libsystemd-login.so and | |
2649 | libsystemd-daemon.so do not make use of IFUNC | |
2650 | anymore. Instead, we now build libsystemd.so multiple times | |
2651 | under these alternative names. This means that the footprint | |
2652 | is drastically increased, but given that these are | |
2653 | transitional compatibility libraries, this should not matter | |
2654 | much. This change has been made necessary to support the ARM | |
2655 | platform for these compatibility libraries, as the ARM | |
2656 | toolchain is not really at the same level as the toolchain | |
2657 | for other architectures like x86 and does not support | |
2658 | IFUNC. Please make sure to use --enable-compat-libs only | |
2659 | during a transitional period! | |

2670 | -- Berlin, 2014-02-24 | |
2671 | ||
2672 | CHANGES WITH 209: | |
2673 | ||
2674 | * A new component "systemd-networkd" has been added that can | |
2675 | be used to configure local network interfaces statically or | |
2676 | via DHCP. It is capable of bringing up bridges, VLANs, and | |
2677 | bonding. Currently, no hook-ups for interactive network | |
2678 | configuration are provided. Use this for your initrd, | |
2679 | container, embedded, or server setup if you need a simple, | |
2680 | yet powerful, network configuration solution. This | |
2681 | configuration subsystem is quite nifty, as it allows wildcard | |
2682 | hotplug matching in interfaces. For example, with a single | |
2683 | configuration snippet, you can configure that all Ethernet | |
2684 | interfaces showing up are automatically added to a bridge, | |
2685 | or similar. It supports link-sensing and more. | |
2686 | ||
2687 | * A new tool "systemd-socket-proxyd" has been added which can | |
2688 | act as a bidirectional proxy for TCP sockets. This is | |
2689 | useful for adding socket activation support to services that | |
2690 | do not actually support socket activation, including virtual | |
2691 | machines and the like. | |
2692 | ||
2693 | * Add a new tool to save/restore rfkill state on | |
2694 | shutdown/boot. | |
2695 | ||
2696 | * Save/restore state of keyboard backlights in addition to | |
2697 | display backlights on shutdown/boot. | |
2698 | ||
2699 | * udev learned a new SECLABEL{} construct to label device | |
2700 | nodes with a specific security label when they appear. For | |
2701 | now, only SECLABEL{selinux} is supported, but the syntax is | |
2702 | prepared for additional security frameworks. | |
2703 | ||
2704 | * udev gained a new scheme to configure link-level attributes | |
2705 | from files in /etc/systemd/network/*.link. These files can | |
2706 | match against MAC address, device path, driver name and type, | |
2707 | and will apply attributes like the naming policy, link speed, | |
2708 | MTU, duplex settings, Wake-on-LAN settings, MAC address, MAC | |
2709 | address assignment policy (randomized, ...). | |
2710 | ||
2711 | * The configuration of network interface naming rules for | |
2712 | "permanent interface names" has changed: a new NamePolicy= | |
2713 | setting in the [Link] section of .link files determines the | |
2714 | priority of possible naming schemes (onboard, slot, mac, | |
2715 | path). The default value of this setting is determined by | |
2716 | /usr/lib/net/links/99-default.link. Old | |
2717 | 80-net-name-slot.rules udev configuration file has been | |
2718 | removed, so local configuration overriding this file should | |
2719 | be adapated to override 99-default.link instead. | |
2720 | ||
2721 | * When the User= switch is used in a unit file, also | |
2722 | initialize $SHELL= based on the user database entry. | |
2723 | ||
2724 | * systemd no longer depends on libdbus. All communication is | |
2725 | now done with sd-bus, systemd's low-level bus library | |
2726 | implementation. | |
2727 | ||
2728 | * kdbus support has been added to PID 1 itself. When kdbus is | |
2729 | enabled, this causes PID 1 to set up the system bus and | |
2730 | enable support for a new ".busname" unit type that | |
2731 | encapsulates bus name activation on kdbus. It works a little | |
2732 | bit like ".socket" units, except for bus names. A new | |
2733 | generator has been added that converts classic dbus1 service | |
2734 | activation files automatically into native systemd .busname | |
2735 | and .service units. | |
2736 | ||
2737 | * sd-bus: add a light-weight vtable implementation that allows | |
2738 | defining objects on the bus with a simple static const | |
2739 | vtable array of its methods, signals and properties. | |
2740 | ||
2741 | * systemd will not generate or install static dbus | |
2742 | introspection data anymore to /usr/share/dbus-1/interfaces, | |
2743 | as the precise format of these files is unclear, and | |
2744 | nothing makes use of it. | |
2745 | ||
2746 | * A proxy daemon is now provided to proxy clients connecting | |
2747 | via classic D-Bus AF_UNIX sockets to kdbus, to provide full | |
2748 | compatibility with classic D-Bus. | |
2749 | ||
2750 | * A bus driver implementation has been added that supports the | |
2751 | classic D-Bus bus driver calls on kdbus, also for | |
2752 | compatibility purposes. | |
2753 | ||
2754 | * A new API "sd-event.h" has been added that implements a | |
2755 | minimal event loop API built around epoll. It provides a | |
2756 | couple of features that direct epoll usage is lacking: | |
2757 | prioritization of events, scales to large numbers of timer | |
2758 | events, per-event timer slack (accuracy), system-wide | |
2759 | coalescing of timer events, exit handlers, watchdog | |
2760 | supervision support using systemd's sd_notify() API, child | |
2761 | process handling. | |
2762 | ||
2763 | * A new API "sd-rntl.h" has been added that provides an API | |
2764 | around the route netlink interface of the kernel, similar in | |
2765 | style to "sd-bus.h". | |
2766 | ||
2767 | * A new API "sd-dhcp-client.h" has been added that provides a | |
2768 | small DHCPv4 client-side implementation. This is used by | |
2769 | "systemd-networkd". | |
2770 | ||
2771 | * There is a new kernel command line option | |
2772 | "systemd.restore_state=0|1". When set to "0", none of the | |
2773 | systemd tools will restore saved runtime state to hardware | |
2774 | devices. More specifically, the rfkill and backlight states | |
2775 | are not restored. | |
2776 | ||
2777 | * The FsckPassNo= compatibility option in mount/service units | |
2778 | has been removed. The fstab generator will now add the | |
2779 | necessary dependencies automatically, and does not require | |
2780 | PID1's support for that anymore. | |
2781 | ||
2782 | * journalctl gained a new switch, --list-boots, that lists | |
2783 | recent boots with their times and boot IDs. | |
2784 | ||
2785 | * The various tools like systemctl, loginctl, timedatectl, | |
2786 | busctl, systemd-run, ... have gained a new switch "-M" to | |
2787 | connect to a specific, local OS container (as direct | |
2788 | connection, without requiring SSH). This works on any | |
2789 | container that is registered with machined, such as those | |
2790 | created by libvirt-lxc or nspawn. | |
2791 | ||
2792 | * systemd-run and systemd-analyze also gained support for "-H" | |
2793 | to connect to remote hosts via SSH. This is particularly | |
2794 | useful for systemd-run because it enables queuing of jobs | |
2795 | onto remote systems. | |
2796 | ||
2797 | * machinectl gained a new command "login" to open a getty | |
2798 | login in any local container. This works with any container | |
2799 | that is registered with machined (such as those created by | |
2800 | libvirt-lxc or nspawn), and which runs systemd inside. | |
2801 | ||
2802 | * machinectl gained a new "reboot" command that may be used to | |
2803 | trigger a reboot on a specific container that is registered | |
2804 | with machined. This works on any container that runs an init | |
2805 | system of some kind. | |
2806 | ||
2807 | * systemctl gained a new "list-timers" command to print a nice | |
2808 | listing of installed timer units with the times they elapse | |
2809 | next. | |
2810 | ||
2811 | * Alternative reboot() parameters may now be specified on the | |
2812 | "systemctl reboot" command line and are passed to the | |
2813 | reboot() system call. | |
2814 | ||
2815 | * systemctl gained a new --job-mode= switch to configure the | |
2816 | mode to queue a job with. This is a more generic version of | |
2817 | --fail, --irreversible, and --ignore-dependencies, which are | |
2818 | still available but not advertised anymore. | |
2819 | ||
2820 | * /etc/systemd/system.conf gained new settings to configure | |
2821 | various default timeouts of units, as well as the default | |
2822 | start limit interval and burst. These may still be overridden | |
2823 | within each Unit. | |
2824 | ||
2825 | * PID1 will now export on the bus profile data of the security | |
2826 | policy upload process (such as the SELinux policy upload to | |
2827 | the kernel). | |
2828 | ||
2829 | * journald: when forwarding logs to the console, include | |
2830 | timestamps (following the setting in | |
2831 | /sys/module/printk/parameters/time). | |
2832 | ||
2833 | * OnCalendar= in timer units now understands the special | |
2834 | strings "yearly" and "annually". (Both are equivalent) | |
2835 | ||
2836 | * The accuracy of timer units is now configurable with the new | |
2837 | AccuracySec= setting. It defaults to 1min. | |
2838 | ||
2839 | * A new dependency type JoinsNamespaceOf= has been added that | |
2840 | allows running two services within the same /tmp and network | |
2841 | namespace, if PrivateNetwork= or PrivateTmp= are used. | |
2842 | ||
2843 | * A new command "cat" has been added to systemctl. It outputs | |
2844 | the original unit file of a unit, and concatenates the | |
2845 | contents of additional "drop-in" unit file snippets, so that | |
2846 | the full configuration is shown. | |
2847 | ||
2848 | * systemctl now supports globbing on the various "list-xyz" | |
2849 | commands, like "list-units" or "list-sockets", as well as on | |
2850 | those commands which take multiple unit names. | |
2851 | ||
2852 | * journalctl's --unit= switch gained support for globbing. | |
2853 | ||
2854 | * All systemd daemons now make use of the watchdog logic so | |
2855 | that systemd automatically notices when they hang. | |
2856 | ||
2857 | * If the $container_ttys environment variable is set, | |
2858 | getty-generator will automatically spawn a getty for each | |
2859 | listed tty. This is useful for container managers to request | |
2860 | login gettys to be spawned on as many ttys as needed. | |
2861 | ||
2862 | * %h, %s, %U specifier support is not available anymore when | |
2863 | used in unit files for PID 1. This is because NSS calls are | |
2864 | not safe from PID 1. They stay available for --user | |
2865 | instances of systemd, and as special case for the root user. | |
2866 | ||
2867 | * loginctl gained a new "--no-legend" switch to turn off output | |
2868 | of the legend text. | |
2869 | ||
2870 | * The "sd-login.h" API gained three new calls: | |
2871 | sd_session_is_remote(), sd_session_get_remote_user(), | |
2872 | sd_session_get_remote_host() to query information about | |
2873 | remote sessions. | |
2874 | ||
2875 | * The udev hardware database now also carries vendor/product | |
2876 | information of SDIO devices. | |
2877 | ||
2878 | * The "sd-daemon.h" API gained a new sd_watchdog_enabled() to | |
2879 | determine whether watchdog notifications are requested by | |
2880 | the system manager. | |
2881 | ||
2882 | * Socket-activated per-connection services now include a | |
2883 | short description of the connection parameters in the | |
2884 | description. | |
2885 | ||
2886 | * tmpfiles gained a new "--boot" option. When this is not used, | |
2887 | only lines where the command character is not suffixed with | |
2888 | "!" are executed. When this option is specified, those | |
2889 | options are executed too. This partitions tmpfiles | |
2890 | directives into those that can be safely executed at any | |
2891 | time, and those which should be run only at boot (for | |
2892 | example, a line that creates /run/nologin). | |
2893 | ||
2894 | * A new API "sd-resolve.h" has been added which provides a simple | |
2895 | asynchronous wrapper around glibc NSS host name resolution | |
2896 | calls, such as getaddrinfo(). In contrast to glibc's | |
2897 | getaddrinfo_a(), it does not use signals. In contrast to most | |
2898 | other asynchronous name resolution libraries, this one does | |
2899 | not reimplement DNS, but reuses NSS, so that alternate | |
2900 | host name resolution systems continue to work, such as mDNS, | |
2901 | LDAP, etc. This API is based on libasyncns, but it has been | |
2902 | cleaned up for inclusion in systemd. | |
2903 | ||
2904 | * The APIs "sd-journal.h", "sd-login.h", "sd-id128.h", | |
2905 | "sd-daemon.h" are no longer found in individual libraries | |
2906 | libsystemd-journal.so, libsystemd-login.so, | |
2907 | libsystemd-id128.so, libsystemd-daemon.so. Instead, we have | |
2908 | merged them into a single library, libsystemd.so, which | |
2909 | provides all symbols. The reason for this is cyclic | |
2910 | dependencies, as these libraries tend to use each other's | |
2911 | symbols. So far, we have managed to workaround that by linking | |
2912 | a copy of a good part of our code into each of these | |
2913 | libraries again and again, which, however, makes certain | |
2914 | things hard to do, like sharing static variables. Also, it | |
2915 | substantially increases footprint. With this change, there | |
2916 | is only one library for the basic APIs systemd | |
2917 | provides. Also, "sd-bus.h", "sd-memfd.h", "sd-event.h", | |
2918 | "sd-rtnl.h", "sd-resolve.h", "sd-utf8.h" are found in this | |
2919 | library as well, however are subject to the --enable-kdbus | |
2920 | switch (see below). Note that "sd-dhcp-client.h" is not part | |
2921 | of this library (this is because it only consumes, never | |
2922 | provides, services of/to other APIs). To make the transition | |
2923 | easy from the separate libraries to the unified one, we | |
2924 | provide the --enable-compat-libs compile-time switch which | |
2925 | will generate stub libraries that are compatible with the | |
2926 | old ones but redirect all calls to the new one. | |
2927 | ||
2928 | * All of the kdbus logic and the new APIs "sd-bus.h", | |
2929 | "sd-memfd.h", "sd-event.h", "sd-rtnl.h", "sd-resolve.h", | |
2930 | and "sd-utf8.h" are compile-time optional via the | |
2931 | "--enable-kdbus" switch, and they are not compiled in by | |
2932 | default. To make use of kdbus, you have to explicitly enable | |
2933 | the switch. Note however, that neither the kernel nor the | |
2934 | userspace API for all of this is considered stable yet. We | |
2935 | want to maintain the freedom to still change the APIs for | |
2936 | now. By specifying this build-time switch, you acknowledge | |
2937 | that you are aware of the instability of the current | |
2938 | APIs. | |
2939 | ||
2940 | * Also, note that while kdbus is pretty much complete, | |
2941 | it lacks one thing: proper policy support. This means you | |
2942 | can build a fully working system with all features; however, | |
2943 | it will be highly insecure. Policy support will be added in | |
2944 | one of the next releases, at the same time that we will | |
2945 | declare the APIs stable. | |
2946 | ||
2947 | * When the kernel command line argument "kdbus" is specified, | |
2948 | systemd will automatically load the kdbus.ko kernel module. At | |
2949 | this stage of development, it is only useful for testing kdbus | |
2950 | and should not be used in production. Note: if "--enable-kdbus" | |
2951 | is specified, and the kdbus.ko kernel module is available, and | |
2952 | "kdbus" is added to the kernel command line, the entire system | |
2953 | runs with kdbus instead of dbus-daemon, with the above mentioned | |
2954 | problem of missing the system policy enforcement. Also a future | |
2955 | version of kdbus.ko or a newer systemd will not be compatible with | |
2956 | each other, and will unlikely be able to boot the machine if only | |
2957 | one of them is updated. | |
2958 | ||
2959 | * systemctl gained a new "import-environment" command which | |
2960 | uploads the caller's environment (or parts thereof) into the | |
2961 | service manager so that it is inherited by services started | |
2962 | by the manager. This is useful to upload variables like | |
2963 | $DISPLAY into the user service manager. | |
2964 | ||
2965 | * A new PrivateDevices= switch has been added to service units | |
2966 | which allows running a service with a namespaced /dev | |
2967 | directory that does not contain any device nodes for | |
2968 | physical devices. More specifically, it only includes devices | |
2969 | such as /dev/null, /dev/urandom, and /dev/zero which are API | |
2970 | entry points. | |
2971 | ||
2972 | * logind has been extended to support behaviour like VT | |
2973 | switching on seats that do not support a VT. This makes | |
2974 | multi-session available on seats that are not the first seat | |
2975 | (seat0), and on systems where kernel support for VTs has | |
2976 | been disabled at compile-time. | |
2977 | ||
2978 | * If a process holds a delay lock for system sleep or shutdown | |
2979 | and fails to release it in time, we will now log its | |
2980 | identity. This makes it easier to identify processes that | |
2981 | cause slow suspends or power-offs. | |
2982 | ||
2983 | * When parsing /etc/crypttab, support for a new key-slot= | |
2984 | option as supported by Debian is added. It allows indicating | |
2985 | which LUKS slot to use on disk, speeding up key loading. | |
2986 | ||
2987 | * The sd_journald_sendv() API call has been checked and | |
2988 | officially declared to be async-signal-safe so that it may | |
2989 | be invoked from signal handlers for logging purposes. | |
2990 | ||
2991 | * Boot-time status output is now enabled automatically after a | |
2992 | short timeout if boot does not progress, in order to give | |
2993 | the user an indication what she or he is waiting for. | |
2994 | ||
2995 | * The boot-time output has been improved to show how much time | |
2996 | remains until jobs expire. | |
2997 | ||
2998 | * The KillMode= switch in service units gained a new possible | |
2999 | value "mixed". If set, and the unit is shut down, then the | |
3000 | initial SIGTERM signal is sent only to the main daemon | |
3001 | process, while the following SIGKILL signal is sent to | |
3002 | all remaining processes of the service. | |
3003 | ||
3004 | * When a scope unit is registered, a new property "Controller" | |
3005 | may be set. If set to a valid bus name, systemd will send a | |
3006 | RequestStop() signal to this name when it would like to shut | |
3007 | down the scope. This may be used to hook manager logic into | |
3008 | the shutdown logic of scope units. Also, scope units may now | |
3009 | be put in a special "abandoned" state, in which case the | |
3010 | manager process which created them takes no further | |
3011 | responsibilities for it. | |
3012 | ||
3013 | * When reading unit files, systemd will now verify | |
3014 | the access mode of these files, and warn about certain | |
3015 | suspicious combinations. This has been added to make it | |
3016 | easier to track down packaging bugs where unit files are | |
3017 | marked executable or world-writable. | |
3018 | ||
3019 | * systemd-nspawn gained a new "--setenv=" switch to set | |
3020 | container-wide environment variables. The similar option in | |
3021 | systemd-activate was renamed from "--environment=" to | |
3022 | "--setenv=" for consistency. | |
3023 | ||
3024 | * systemd-nspawn has been updated to create a new kdbus domain | |
3025 | for each container that is invoked, thus allowing each | |
3026 | container to have its own set of system and user buses, | |
3027 | independent of the host. | |
3028 | ||
3029 | * systemd-nspawn gained a new --drop-capability= switch to run | |
3030 | the container with less capabilities than the default. Both | |
3031 | --drop-capability= and --capability= now take the special | |
3032 | string "all" for dropping or keeping all capabilities. | |
3033 | ||
3034 | * systemd-nspawn gained new switches for executing containers | |
3035 | with specific SELinux labels set. | |
3036 | ||
3037 | * systemd-nspawn gained a new --quiet switch to not generate | |
3038 | any additional output but the container's own console | |
3039 | output. | |
3040 | ||
3041 | * systemd-nspawn gained a new --share-system switch to run a | |
3042 | container without PID namespacing enabled. | |
3043 | ||
3044 | * systemd-nspawn gained a new --register= switch to control | |
3045 | whether the container is registered with systemd-machined or | |
3046 | not. This is useful for containers that do not run full | |
3047 | OS images, but only specific apps. | |
3048 | ||
3049 | * systemd-nspawn gained a new --keep-unit which may be used | |
3050 | when invoked as the only program from a service unit, and | |
3051 | results in registration of the unit service itself in | |
3052 | systemd-machined, instead of a newly opened scope unit. | |
3053 | ||
3054 | * systemd-nspawn gained a new --network-interface= switch for | |
3055 | moving arbitrary interfaces to the container. The new | |
3056 | --network-veth switch creates a virtual Ethernet connection | |
3057 | between host and container. The new --network-bridge= | |
3058 | switch then allows assigning the host side of this virtual | |
3059 | Ethernet connection to a bridge device. | |
3060 | ||
3061 | * systemd-nspawn gained a new --personality= switch for | |
3062 | setting the kernel personality for the container. This is | |
3063 | useful when running a 32-bit container on a 64-bit host. A | |
3064 | similar option Personality= is now also available for service | |
3065 | units to use. | |
3066 | ||
3067 | * logind will now also track a "Desktop" identifier for each | |
3068 | session which encodes the desktop environment of it. This is | |
3069 | useful for desktop environments that want to identify | |
3070 | multiple running sessions of itself easily. | |
3071 | ||
3072 | * A new SELinuxContext= setting for service units has been | |
3073 | added that allows setting a specific SELinux execution | |
3074 | context for a service. | |
3075 | ||
3076 | * Most systemd client tools will now honour $SYSTEMD_LESS for | |
3077 | settings of the "less" pager. By default, these tools will | |
3078 | override $LESS to allow certain operations to work, such as | |
3079 | jump-to-the-end. With $SYSTEMD_LESS, it is possible to | |
3080 | influence this logic. | |
3081 | ||
3082 | * systemd's "seccomp" hook-up has been changed to make use of | |
3083 | the libseccomp library instead of using its own | |
3084 | implementation. This has benefits for portability among | |
3085 | other things. | |
3086 | ||
3087 | * For usage together with SystemCallFilter=, a new | |
3088 | SystemCallErrorNumber= setting has been introduced that | |
3089 | allows configuration of a system error number to be returned | |
3090 | on filtered system calls, instead of immediately killing the | |
3091 | process. Also, SystemCallArchitectures= has been added to | |
3092 | limit access to system calls of a particular architecture | |
3093 | (in order to turn off support for unused secondary | |
3094 | architectures). There is also a global | |
3095 | SystemCallArchitectures= setting in system.conf now to turn | |
3096 | off support for non-native system calls system-wide. | |
3097 | ||
3098 | * systemd requires a kernel with a working name_to_handle_at(), | |
3099 | please see the kernel config requirements in the README file. | |

3128 | CHANGES WITH 208: | |
3129 | ||
3130 | * logind has gained support for facilitating privileged input | |
3131 | and drm device access for unprivileged clients. This work is | |
3132 | useful to allow Wayland display servers (and similar | |
3133 | programs, such as kmscon) to run under the user's ID and | |
3134 | access input and drm devices which are normally | |
3135 | protected. When this is used (and the kernel is new enough) | |
3136 | logind will "mute" IO on the file descriptors passed to | |
3137 | Wayland as long as it is in the background and "unmute" it | |
3138 | if it returns into the foreground. This allows secure | |
3139 | session switching without allowing background sessions to | |
3140 | eavesdrop on input and display data. This also introduces | |
3141 | session switching support if VT support is turned off in the | |
3142 | kernel, and on seats that are not seat0. | |
3143 | ||
3144 | * A new kernel command line option luks.options= is understood | |
3145 | now which allows specifying LUKS options for usage for LUKS | |
3146 | encrypted partitions specified with luks.uuid=. | |
3147 | ||
3148 | * tmpfiles.d(5) snippets may now use specifier expansion in | |
3149 | path names. More specifically %m, %b, %H, %v, are now | |
3150 | replaced by the local machine id, boot id, hostname, and | |
3151 | kernel version number. | |
3152 | ||
3153 | * A new tmpfiles.d(5) command "m" has been introduced which | |
3154 | may be used to change the owner/group/access mode of a file | |
3155 | or directory if it exists, but do nothing if it does not. | |
3156 | ||
3157 | * This release removes high-level support for the | |
3158 | MemorySoftLimit= cgroup setting. The underlying kernel | |
3159 | cgroup attribute memory.soft_limit= is currently badly | |
3160 | designed and likely to be removed from the kernel API in its | |
3161 | current form, hence we should not expose it for now. | |
3162 | ||
3163 | * The memory.use_hierarchy cgroup attribute is now enabled for | |
3164 | all cgroups systemd creates in the memory cgroup | |
3165 | hierarchy. This option is likely to be come the built-in | |
3166 | default in the kernel anyway, and the non-hierarchical mode | |
3167 | never made much sense in the intrinsically hierarchical | |
3168 | cgroup system. | |
3169 | ||
3170 | * A new field _SYSTEMD_SLICE= is logged along with all journal | |
3171 | messages containing the slice a message was generated | |
3172 | from. This is useful to allow easy per-customer filtering of | |
3173 | logs among other things. | |
3174 | ||
3175 | * systemd-journald will no longer adjust the group of journal | |
3176 | files it creates to the "systemd-journal" group. Instead we | |
3177 | rely on the journal directory to be owned by the | |
3178 | "systemd-journal" group, and its setgid bit set, so that the | |
3179 | kernel file system layer will automatically enforce that | |
3180 | journal files inherit this group assignment. The reason for | |
3181 | this change is that we cannot allow NSS look-ups from | |
3182 | journald which would be necessary to resolve | |
3183 | "systemd-journal" to a numeric GID, because this might | |
3184 | create deadlocks if NSS involves synchronous queries to | |
3185 | other daemons (such as nscd, or sssd) which in turn are | |
3186 | logging clients of journald and might block on it, which | |
3187 | would then dead lock. A tmpfiles.d(5) snippet included in | |
3188 | systemd will make sure the setgid bit and group are | |
3189 | properly set on the journal directory if it exists on every | |
3190 | boot. However, we recommend adjusting it manually after | |
3191 | upgrades too (or from RPM scriptlets), so that the change is | |
3192 | not delayed until next reboot. | |
3193 | ||
3194 | * Backlight and random seed files in /var/lib/ have moved into | |
3195 | the /var/lib/systemd/ directory, in order to centralize all | |
3196 | systemd generated files in one directory. | |
3197 | ||
3198 | * Boot time performance measurements (as displayed by | |
3199 | "systemd-analyze" for example) will now read ACPI 5.0 FPDT | |
3200 | performance information if that's available to determine how | |
3201 | much time BIOS and boot loader initialization required. With | |
3202 | a sufficiently new BIOS you hence no longer need to boot | |
3203 | with Gummiboot to get access to such information. | |

3214 | ||
3215 | CHANGES WITH 207: | |
3216 | ||
3217 | * The Restart= option for services now understands a new | |
3218 | on-watchdog setting, which will restart the service | |
3219 | automatically if the service stops sending out watchdog keep | |
3220 | alive messages (as configured with WatchdogSec=). | |
3221 | ||
3222 | * The getty generator (which is responsible for bringing up a | |
3223 | getty on configured serial consoles) will no longer only | |
3224 | start a getty on the primary kernel console but on all | |
3225 | others, too. This makes the order in which console= is | |
3226 | specified on the kernel command line less important. | |
3227 | ||
3228 | * libsystemd-logind gained a new sd_session_get_vt() call to | |
3229 | retrieve the VT number of a session. | |
3230 | ||
3231 | * If the option "tries=0" is set for an entry of /etc/crypttab | |
3232 | its passphrase is queried indefinitely instead of any | |
3233 | maximum number of tries. | |
3234 | ||
3235 | * If a service with a configure PID file terminates its PID | |
3236 | file will now be removed automatically if it still exists | |
3237 | afterwards. This should put an end to stale PID files. | |
3238 | ||
3239 | * systemd-run will now also take relative binary path names | |
3240 | for execution and no longer insists on absolute paths. | |
3241 | ||
3242 | * InaccessibleDirectories= and ReadOnlyDirectories= now take | |
3243 | paths that are optionally prefixed with "-" to indicate that | |
3244 | it should not be considered a failure if they do not exist. | |
3245 | ||
3246 | * journalctl -o (and similar commands) now understands a new | |
3247 | output mode "short-precise", it is similar to "short" but | |
3248 | shows timestamps with usec accuracy. | |
3249 | ||
3250 | * The option "discard" (as known from Debian) is now | |
3251 | synonymous to "allow-discards" in /etc/crypttab. In fact, | |
3252 | "discard" is preferred now (since it is easier to remember | |
3253 | and type). | |
3254 | ||
3255 | * Some licensing clean-ups were made, so that more code is now | |
3256 | LGPL-2.1 licensed than before. | |
3257 | ||
3258 | * A minimal tool to save/restore the display backlight | |
3259 | brightness across reboots has been added. It will store the | |
3260 | backlight setting as late as possible at shutdown, and | |
3261 | restore it as early as possible during reboot. | |
3262 | ||
3263 | * A logic to automatically discover and enable home and swap | |
3264 | partitions on GPT disks has been added. With this in place | |
3265 | /etc/fstab becomes optional for many setups as systemd can | |
3266 | discover certain partitions located on the root disk | |
3267 | automatically. Home partitions are recognized under their | |
3268 | GPT type ID 933ac7e12eb44f13b8440e14e2aef915. Swap | |
3269 | partitions are recognized under their GPT type ID | |
3270 | 0657fd6da4ab43c484e50933c84b4f4f. | |
3271 | ||
3272 | * systemd will no longer pass any environment from the kernel | |
3273 | or initrd to system services. If you want to set an | |
3274 | environment for all services, do so via the kernel command | |
3275 | line systemd.setenv= assignment. | |
3276 | ||
3277 | * The systemd-sysctl tool no longer natively reads the file | |
3278 | /etc/sysctl.conf. If desired, the file should be symlinked | |
3279 | from /etc/sysctl.d/99-sysctl.conf. Apart from providing | |
3280 | legacy support by a symlink rather than built-in code, it | |
3281 | also makes the otherwise hidden order of application of the | |
3282 | different files visible. (Note that this partly reverts to a | |
3283 | pre-198 application order of sysctl knobs!) | |
3284 | ||
3285 | * The "systemctl set-log-level" and "systemctl dump" commands | |
3286 | have been moved to systemd-analyze. | |
3287 | ||
3288 | * systemd-run learned the new --remain-after-exit switch, | |
3289 | which causes the scope unit not to be cleaned up | |
3290 | automatically after the process terminated. | |
3291 | ||
3292 | * tmpfiles learned a new --exclude-prefix= switch to exclude | |
3293 | certain paths from operation. | |
3294 | ||
3295 | * journald will now automatically flush all messages to disk | |
3296 | as soon as a message at the log level CRIT, ALERT or EMERG | |
3297 | is received. | |

3314 | ||
3315 | CHANGES WITH 206: | |
3316 | ||
3317 | * The documentation has been updated to cover the various new | |
3318 | concepts introduced with 205. | |
3319 | ||
3320 | * Unit files now understand the new %v specifier which | |
3321 | resolves to the kernel version string as returned by "uname | |
3322 | -r". | |
3323 | ||
3324 | * systemctl now supports filtering the unit list output by | |
3325 | load state, active state and sub state, using the new | |
3326 | --state= parameter. | |
3327 | ||
3328 | * "systemctl status" will now show the results of the | |
3329 | condition checks (like ConditionPathExists= and similar) of | |
3330 | the last start attempts of the unit. They are also logged to | |
3331 | the journal. | |
3332 | ||
3333 | * "journalctl -b" may now be used to look for boot output of a | |
3334 | specific boot. Try "journalctl -b -1" for the previous boot, | |
3335 | but the syntax is substantially more powerful. | |
3336 | ||
3337 | * "journalctl --show-cursor" has been added which prints the | |
3338 | cursor string the last shown log line. This may then be used | |
3339 | with the new "journalctl --after-cursor=" switch to continue | |
3340 | browsing logs from that point on. | |
3341 | ||
3342 | * "journalctl --force" may now be used to force regeneration | |
3343 | of an FSS key. | |
3344 | ||
3345 | * Creation of "dead" device nodes has been moved from udev | |
3346 | into kmod and tmpfiles. Previously, udev would read the kmod | |
3347 | databases to pre-generate dead device nodes based on meta | |
3348 | information contained in kernel modules, so that these would | |
3349 | be auto-loaded on access rather then at boot. As this | |
3350 | does not really have much to do with the exposing actual | |
3351 | kernel devices to userspace this has always been slightly | |
3352 | alien in the udev codebase. Following the new scheme kmod | |
3353 | will now generate a runtime snippet for tmpfiles from the | |
3354 | module meta information and it now is tmpfiles' job to the | |
3355 | create the nodes. This also allows overriding access and | |
3356 | other parameters for the nodes using the usual tmpfiles | |
3357 | facilities. As side effect this allows us to remove the | |
3358 | CAP_SYS_MKNOD capability bit from udevd entirely. | |
3359 | ||
3360 | * logind's device ACLs may now be applied to these "dead" | |
3361 | devices nodes too, thus finally allowing managed access to | |
3362 | devices such as /dev/snd/sequencer whithout loading the | |
3363 | backing module right-away. | |
3364 | ||
3365 | * A new RPM macro has been added that may be used to apply | |
3366 | tmpfiles configuration during package installation. | |
3367 | ||
3368 | * systemd-detect-virt and ConditionVirtualization= now can | |
3369 | detect User-Mode-Linux machines (UML). | |
3370 | ||
3371 | * journald will now implicitly log the effective capabilities | |
3372 | set of processes in the message metadata. | |
3373 | ||
3374 | * systemd-cryptsetup has gained support for TrueCrypt volumes. | |
3375 | ||
3376 | * The initrd interface has been simplified (more specifically, | |
3377 | support for passing performance data via environment | |
3378 | variables and fsck results via files in /run has been | |
3379 | removed). These features were non-essential, and are | |
3380 | nowadays available in a much nicer way by having systemd in | |
3381 | the initrd serialize its state and have the hosts systemd | |
3382 | deserialize it again. | |
3383 | ||
3384 | * The udev "keymap" data files and tools to apply keyboard | |
3385 | specific mappings of scan to key codes, and force-release | |
3386 | scan code lists have been entirely replaced by a udev | |
3387 | "keyboard" builtin and a hwdb data file. | |
3388 | ||
3389 | * systemd will now honour the kernel's "quiet" command line | |
3390 | argument also during late shutdown, resulting in a | |
3391 | completely silent shutdown when used. | |
3392 | ||
3393 | * There's now an option to control the SO_REUSEPORT socket | |
3394 | option in .socket units. | |
3395 | ||
3396 | * Instance units will now automatically get a per-template | |
3397 | subslice of system.slice unless something else is explicitly | |
3398 | configured. For example, instances of sshd@.service will now | |
3399 | implicitly be placed in system-sshd.slice rather than | |
3400 | system.slice as before. | |
3401 | ||
3402 | * Test coverage support may now be enabled at build time. | |

3412 | -- Berlin, 2013-07-23 | |
3413 | ||
3414 | CHANGES WITH 205: | |
3415 | ||
3416 | * Two new unit types have been introduced: | |
3417 | ||
3418 | Scope units are very similar to service units, however, are | |
3419 | created out of pre-existing processes -- instead of PID 1 | |
3420 | forking off the processes. By using scope units it is | |
3421 | possible for system services and applications to group their | |
3422 | own child processes (worker processes) in a powerful way | |
3423 | which then maybe used to organize them, or kill them | |
3424 | together, or apply resource limits on them. | |
3425 | ||
3426 | Slice units may be used to partition system resources in an | |
3427 | hierarchical fashion and then assign other units to them. By | |
3428 | default there are now three slices: system.slice (for all | |
3429 | system services), user.slice (for all user sessions), | |
3430 | machine.slice (for VMs and containers). | |
3431 | ||
3432 | Slices and scopes have been introduced primarily in | |
3433 | context of the work to move cgroup handling to a | |
3434 | single-writer scheme, where only PID 1 | |
3435 | creates/removes/manages cgroups. | |
3436 | ||
3437 | * There's a new concept of "transient" units. In contrast to | |
3438 | normal units these units are created via an API at runtime, | |
3439 | not from configuration from disk. More specifically this | |
3440 | means it is now possible to run arbitrary programs as | |
3441 | independent services, with all execution parameters passed | |
3442 | in via bus APIs rather than read from disk. Transient units | |
3443 | make systemd substantially more dynamic then it ever was, | |
3444 | and useful as a general batch manager. | |
3445 | ||
3446 | * logind has been updated to make use of scope and slice units | |
3447 | for managing user sessions. As a user logs in he will get | |
3448 | his own private slice unit, to which all sessions are added | |
3449 | as scope units. We also added support for automatically | |
3450 | adding an instance of user@.service for the user into the | |
3451 | slice. Effectively logind will no longer create cgroup | |
3452 | hierarchies on its own now, it will defer entirely to PID 1 | |
3453 | for this by means of scope, service and slice units. Since | |
3454 | user sessions this way become entities managed by PID 1 | |
3455 | the output of "systemctl" is now a lot more comprehensive. | |
3456 | ||
3457 | * A new mini-daemon "systemd-machined" has been added which | |
3458 | may be used by virtualization managers to register local | |
3459 | VMs/containers. nspawn has been updated accordingly, and | |
3460 | libvirt will be updated shortly. machined will collect a bit | |
3461 | of meta information about the VMs/containers, and assign | |
3462 | them their own scope unit (see above). The collected | |
3463 | meta-data is then made available via the "machinectl" tool, | |
3464 | and exposed in "ps" and similar tools. machined/machinectl | |
3465 | is compile-time optional. | |
3466 | ||
3467 | * As discussed earlier, the low-level cgroup configuration | |
3468 | options ControlGroup=, ControlGroupModify=, | |
3469 | ControlGroupPersistent=, ControlGroupAttribute= have been | |
3470 | removed. Please use high-level attribute settings instead as | |
3471 | well as slice units. | |
3472 | ||
3473 | * A new bus call SetUnitProperties() has been added to alter | |
3474 | various runtime parameters of a unit. This is primarily | |
3475 | useful to alter cgroup parameters dynamically in a nice way, | |
3476 | but will be extended later on to make more properties | |
3477 | modifiable at runtime. systemctl gained a new set-properties | |
3478 | command that wraps this call. | |
3479 | ||
3480 | * A new tool "systemd-run" has been added which can be used to | |
3481 | run arbitrary command lines as transient services or scopes, | |
3482 | while configuring a number of settings via the command | |
3483 | line. This tool is currently very basic, however already | |
3484 | very useful. We plan to extend this tool to even allow | |
3485 | queuing of execution jobs with time triggers from the | |
3486 | command line, similar in fashion to "at". | |
3487 | ||
3488 | * nspawn will now inform the user explicitly that kernels with | |
3489 | audit enabled break containers, and suggest the user to turn | |
3490 | off audit. | |
3491 | ||
3492 | * Support for detecting the IMA and AppArmor security | |
3493 | frameworks with ConditionSecurity= has been added. | |
3494 | ||
3495 | * journalctl gained a new "-k" switch for showing only kernel | |
3496 | messages, mimicking dmesg output; in addition to "--user" | |
3497 | and "--system" switches for showing only user's own logs | |
3498 | and system logs. | |
3499 | ||
3500 | * systemd-delta can now show information about drop-in | |
3501 | snippets extending unit files. | |
3502 | ||
3503 | * libsystemd-bus has been substantially updated but is still | |
3504 | not available as public API. | |
3505 | ||
3506 | * systemd will now look for the "debug" argument on the kernel | |
3507 | command line and enable debug logging, similar to what | |
3508 | "systemd.log_level=debug" already did before. | |
3509 | ||
3510 | * "systemctl set-default", "systemctl get-default" has been | |
3511 | added to configure the default.target symlink, which | |
3512 | controls what to boot into by default. | |
3513 | ||
3514 | * "systemctl set-log-level" has been added as a convenient | |
3515 | way to raise and lower systemd logging threshold. | |
3516 | ||
3517 | * "systemd-analyze plot" will now show the time the various | |
3518 | generators needed for execution, as well as information | |
3519 | about the unit file loading. | |
3520 | ||
3521 | * libsystemd-journal gained a new sd_journal_open_files() call | |
3522 | for opening specific journal files. journactl also gained a | |
3523 | new switch to expose this new functionality. Previously we | |
3524 | only supported opening all files from a directory, or all | |
3525 | files from the system, as opening individual files only is | |
3526 | racy due to journal file rotation. | |
3527 | ||
3528 | * systemd gained the new DefaultEnvironment= setting in | |
3529 | /etc/systemd/system.conf to set environment variables for | |
3530 | all services. | |
3531 | ||
3532 | * If a privileged process logs a journal message with the | |
3533 | OBJECT_PID= field set, then journald will automatically | |
3534 | augment this with additional OBJECT_UID=, OBJECT_GID=, | |
3535 | OBJECT_COMM=, OBJECT_EXE=, ... fields. This is useful if | |
3536 | system services want to log events about specific client | |
3537 | processes. journactl/systemctl has been updated to make use | |
3538 | of this information if all log messages regarding a specific | |
3539 | unit is requested. | |

3555 | CHANGES WITH 204: | |
3556 | ||
3557 | * The Python bindings gained some minimal support for the APIs | |
3558 | exposed by libsystemd-logind. | |
3559 | ||
3560 | * ConditionSecurity= gained support for detecting SMACK. Since | |
3561 | this condition already supports SELinux and AppArmor we only | |
3562 | miss IMA for this. Patches welcome! | |
3563 | ||

3566 | ||
3567 | CHANGES WITH 203: | |
3568 | ||
3569 | * systemd-nspawn will now create /etc/resolv.conf if | |
3570 | necessary, before bind-mounting the host's file onto it. | |
3571 | ||
3572 | * systemd-nspawn will now store meta information about a | |
3573 | container on the container's cgroup as extended attribute | |
3574 | fields, including the root directory. | |
3575 | ||
3576 | * The cgroup hierarchy has been reworked in many ways. All | |
3577 | objects any of the components systemd creates in the cgroup | |
3578 | tree are now suffixed. More specifically, user sessions are | |
3579 | now placed in cgroups suffixed with ".session", users in | |
3580 | cgroups suffixed with ".user", and nspawn containers in | |
3581 | cgroups suffixed with ".nspawn". Furthermore, all cgroup | |
3582 | names are now escaped in a simple scheme to avoid collision | |
3583 | of userspace object names with kernel filenames. This work | |
3584 | is preparation for making these objects relocatable in the | |
3585 | cgroup tree, in order to allow easy resource partitioning of | |
3586 | these objects without causing naming conflicts. | |
3587 | ||
3588 | * systemctl list-dependencies gained the new switches | |
3589 | --plain, --reverse, --after and --before. | |
3590 | ||
3591 | * systemd-inhibit now shows the process name of processes that | |
3592 | have taken an inhibitor lock. | |
3593 | ||
3594 | * nss-myhostname will now also resolve "localhost" | |
3595 | implicitly. This makes /etc/hosts an optional file and | |
3596 | nicely handles that on IPv6 ::1 maps to both "localhost" and | |
3597 | the local hostname. | |
3598 | ||
3599 | * libsystemd-logind.so gained a new call | |
3600 | sd_get_machine_names() to enumerate running containers and | |
3601 | VMs (currently only supported by very new libvirt and | |
3602 | nspawn). sd_login_monitor can now be used to watch | |
3603 | VMs/containers coming and going. | |
3604 | ||
3605 | * .include is not allowed recursively anymore, and only in | |
3606 | unit files. Usually it is better to use drop-in snippets in | |
3607 | .d/*.conf anyway, as introduced with systemd 198. | |
3608 | ||
3609 | * systemd-analyze gained a new "critical-chain" command that | |
3610 | determines the slowest chain of units run during system | |
3611 | boot-up. It is very useful for tracking down where | |
3612 | optimizing boot time is the most beneficial. | |
3613 | ||
3614 | * systemd will no longer allow manipulating service paths in | |
3615 | the name=systemd:/system cgroup tree using ControlGroup= in | |
3616 | units. (But is still fine with it in all other dirs.) | |
3617 | ||
3618 | * There's a new systemd-nspawn@.service service file that may | |
3619 | be used to easily run nspawn containers as system | |
3620 | services. With the container's root directory in | |
3621 | /var/lib/container/foobar it is now sufficient to run | |
3622 | "systemctl start systemd-nspawn@foobar.service" to boot it. | |
3623 | ||
3624 | * systemd-cgls gained a new parameter "--machine" to list only | |
3625 | the processes within a certain container. | |
3626 | ||
3627 | * ConditionSecurity= now can check for "apparmor". We still | |
3628 | are lacking checks for SMACK and IMA for this condition | |
3629 | check though. Patches welcome! | |
3630 | ||
3631 | * A new configuration file /etc/systemd/sleep.conf has been | |
3632 | added that may be used to configure which kernel operation | |
3633 | systemd is supposed to execute when "suspend", "hibernate" | |
3634 | or "hybrid-sleep" is requested. This makes the new kernel | |
3635 | "freeze" state accessible to the user. | |
3636 | ||
3637 | * ENV{SYSTEMD_WANTS} in udev rules will now implicitly escape | |
3638 | the passed argument if applicable. | |

3649 | CHANGES WITH 202: | |
3650 | ||
3651 | * The output of 'systemctl list-jobs' got some polishing. The | |
3652 | '--type=' argument may now be passed more than once. A new | |
3653 | command 'systemctl list-sockets' has been added which shows | |
3654 | a list of kernel sockets systemd is listening on with the | |
3655 | socket units they belong to, plus the units these socket | |
3656 | units activate. | |
3657 | ||
3658 | * The experimental libsystemd-bus library got substantial | |
3659 | updates to work in conjunction with the (also experimental) | |
3660 | kdbus kernel project. It works well enough to exchange | |
3661 | messages with some sophistication. Note that kdbus is not | |
3662 | ready yet, and the library is mostly an elaborate test case | |
3663 | for now, and not installable. | |
3664 | ||
3665 | * systemd gained a new unit 'systemd-static-nodes.service' | |
3666 | that generates static device nodes earlier during boot, and | |
3667 | can run in conjunction with udev. | |
3668 | ||
3669 | * libsystemd-login gained a new call sd_pid_get_user_unit() | |
3670 | to retrieve the user systemd unit a process is running | |
3671 | in. This is useful for systems where systemd is used as | |
3672 | session manager. | |
3673 | ||
3674 | * systemd-nspawn now places all containers in the new /machine | |
3675 | top-level cgroup directory in the name=systemd | |
3676 | hierarchy. libvirt will soon do the same, so that we get a | |
3677 | uniform separation of /system, /user and /machine for system | |
3678 | services, user processes and containers/virtual | |
3679 | machines. This new cgroup hierarchy is also useful to stick | |
3680 | stable names to specific container instances, which can be | |
3681 | recognized later this way (this name may be controlled | |
3682 | via systemd-nspawn's new -M switch). libsystemd-login also | |
3683 | gained a new call sd_pid_get_machine_name() to retrieve the | |
3684 | name of the container/VM a specific process belongs to. | |
3685 | ||
3686 | * bootchart can now store its data in the journal. | |
3687 | ||
3688 | * libsystemd-journal gained a new call | |
3689 | sd_journal_add_conjunction() for AND expressions to the | |
3690 | matching logic. This can be used to express more complex | |
3691 | logical expressions. | |
3692 | ||
3693 | * journactl can now take multiple --unit= and --user-unit= | |
3694 | switches. | |
3695 | ||
3696 | * The cryptsetup logic now understands the "luks.key=" kernel | |
3697 | command line switch for specifying a file to read the | |
3698 | decryption key from. Also, if a configured key file is not | |
3699 | found the tool will now automatically fall back to prompting | |
3700 | the user. | |
3701 | ||
3702 | * Python systemd.journal module was updated to wrap recently | |
3703 | added functions from libsystemd-journal. The interface was | |
3704 | changed to bring the low level interface in s.j._Reader | |
3705 | closer to the C API, and the high level interface in | |
3706 | s.j.Reader was updated to wrap and convert all data about | |
3707 | an entry. | |

3715 | ||
3716 | CHANGES WITH 201: | |
3717 | ||
3718 | * journalctl --update-catalog now understands a new --root= | |
3719 | option to operate on catalogs found in a different root | |
3720 | directory. | |
3721 | ||
3722 | * During shutdown after systemd has terminated all running | |
3723 | services a final killing loop kills all remaining left-over | |
3724 | processes. We will now print the name of these processes | |
3725 | when we send SIGKILL to them, since this usually indicates a | |
3726 | problem. | |
3727 | ||
3728 | * If /etc/crypttab refers to password files stored on | |
3729 | configured mount points automatic dependencies will now be | |
3730 | generated to ensure the specific mount is established first | |
3731 | before the key file is attempted to be read. | |
3732 | ||
3733 | * 'systemctl status' will now show information about the | |
3734 | network sockets a socket unit is listening on. | |
3735 | ||
3736 | * 'systemctl status' will also shown information about any | |
3737 | drop-in configuration file for units. (Drop-In configuration | |
3738 | files in this context are files such as | |
3739 | /etc/systemd/systemd/foobar.service.d/*.conf) | |
3740 | ||
3741 | * systemd-cgtop now optionally shows summed up CPU times of | |
3742 | cgroups. Press '%' while running cgtop to switch between | |
3743 | percentage and absolute mode. This is useful to determine | |
3744 | which cgroups use up the most CPU time over the entire | |
3745 | runtime of the system. systemd-cgtop has also been updated | |
3746 | to be 'pipeable' for processing with further shell tools. | |
3747 | ||
3748 | * 'hostnamectl set-hostname' will now allow setting of FQDN | |
3749 | hostnames. | |
3750 | ||
3751 | * The formatting and parsing of time span values has been | |
3752 | changed. The parser now understands fractional expressions | |
3753 | such as "5.5h". The formatter will now output fractional | |
3754 | expressions for all time spans under 1min, i.e. "5.123456s" | |
3755 | rather than "5s 123ms 456us". For time spans under 1s | |
3756 | millisecond values are shown, for those under 1ms | |
3757 | microsecond values are shown. This should greatly improve | |
3758 | all time-related output of systemd. | |
3759 | ||
3760 | * libsystemd-login and libsystemd-journal gained new | |
3761 | functions for querying the poll() events mask and poll() | |
3762 | timeout value for integration into arbitrary event | |
3763 | loops. | |
3764 | ||
3765 | * localectl gained the ability to list available X11 keymaps | |
3766 | (models, layouts, variants, options). | |
3767 | ||
3768 | * 'systemd-analyze dot' gained the ability to filter for | |
3769 | specific units via shell-style globs, to create smaller, | |
3770 | more useful graphs. I.e. it is now possible to create simple | |
3771 | graphs of all the dependencies between only target units, or | |
3772 | of all units that Avahi has dependencies with. | |

3782 | CHANGES WITH 200: | |
3783 | ||
3784 | * The boot-time readahead implementation for rotating media | |
3785 | will now read the read-ahead data in multiple passes which | |
3786 | consist of all read requests made in equidistant time | |
3787 | intervals. This means instead of strictly reading read-ahead | |
3788 | data in its physical order on disk we now try to find a | |
3789 | middle ground between physical and access time order. | |
3790 | ||
3791 | * /etc/os-release files gained a new BUILD_ID= field for usage | |
3792 | on operating systems that provide continuous builds of OS | |
3793 | images. | |

3799 | CHANGES WITH 199: | |
3800 | ||
3801 | * systemd-python gained an API exposing libsystemd-daemon. | |
3802 | ||
3803 | * The SMACK setup logic gained support for uploading CIPSO | |
3804 | security policy. | |
3805 | ||
3806 | * Behaviour of PrivateTmp=, ReadWriteDirectories=, | |
3807 | ReadOnlyDirectories= and InaccessibleDirectories= has | |
3808 | changed. The private /tmp and /var/tmp directories are now | |
3809 | shared by all processes of a service (which means | |
3810 | ExecStartPre= may now leave data in /tmp that ExecStart= of | |
3811 | the same service can still access). When a service is | |
3812 | stopped its temporary directories are immediately deleted | |
3813 | (normal clean-up with tmpfiles is still done in addition to | |
3814 | this though). | |
3815 | ||
3816 | * By default, systemd will now set a couple of sysctl | |
3817 | variables in the kernel: the safe sysrq options are turned | |
3818 | on, IP route verification is turned on, and source routing | |
3819 | disabled. The recently added hardlink and softlink | |
3820 | protection of the kernel is turned on. These settings should | |
3821 | be reasonably safe, and good defaults for all new systems. | |
3822 | ||
3823 | * The predictable network naming logic may now be turned off | |
3824 | with a new kernel command line switch: net.ifnames=0. | |
3825 | ||
3826 | * A new libsystemd-bus module has been added that implements a | |
3827 | pretty complete D-Bus client library. For details see: | |
3828 | ||
3829 | http://lists.freedesktop.org/archives/systemd-devel/2013-March/009797.html | |
3830 | ||
3831 | * journald will now explicitly flush the journal files to disk | |
3832 | at the latest 5min after each write. The file will then also | |
3833 | be marked offline until the next write. This should increase | |
3834 | reliability in case of a crash. The synchronization delay | |
3835 | can be configured via SyncIntervalSec= in journald.conf. | |
3836 | ||
3837 | * There's a new remote-fs-setup.target unit that can be used | |
3838 | to pull in specific services when at least one remote file | |
3839 | system is to be mounted. | |
3840 | ||
3841 | * There are new targets timers.target and paths.target as | |
3842 | canonical targets to pull user timer and path units in | |
3843 | from. This complements sockets.target with a similar | |
3844 | purpose for socket units. | |
3845 | ||
3846 | * libudev gained a new call udev_device_set_attribute_value() | |
3847 | to set sysfs attributes of a device. | |
3848 | ||
3849 | * The udev daemon now sets the default number of worker | |
3850 | processes executed in parallel based on the number of available | |
3851 | CPUs instead of the amount of available RAM. This is supposed | |
3852 | to provide a more reliable default and limit a too aggressive | |
3853 | paralellism for setups with 1000s of devices connected. | |

3865 | CHANGES WITH 198: | |
3866 | ||
3867 | * Configuration of unit files may now be extended via drop-in | |
3868 | files without having to edit/override the unit files | |
3869 | themselves. More specifically, if the administrator wants to | |
3870 | change one value for a service file foobar.service he can | |
3871 | now do so by dropping in a configuration snippet into | |
3872 | /etc/systemd/system/foobar.service.d/*.conf. The unit logic | |
3873 | will load all these snippets and apply them on top of the | |
3874 | main unit configuration file, possibly extending or | |
3875 | overriding its settings. Using these drop-in snippets is | |
3876 | generally nicer than the two earlier options for changing | |
3877 | unit files locally: copying the files from | |
3878 | /usr/lib/systemd/system/ to /etc/systemd/system/ and editing | |
3879 | them there; or creating a new file in /etc/systemd/system/ | |
3880 | that incorporates the original one via ".include". Drop-in | |
3881 | snippets into these .d/ directories can be placed in any | |
3882 | directory systemd looks for units in, and the usual | |
3883 | overriding semantics between /usr/lib, /etc and /run apply | |
3884 | for them too. | |
3885 | ||
3886 | * Most unit file settings which take lists of items can now be | |
3887 | reset by assigning the empty string to them. For example, | |
3888 | normally, settings such as Environment=FOO=BAR append a new | |
3889 | environment variable assignment to the environment block, | |
3890 | each time they are used. By assigning Environment= the empty | |
3891 | string the environment block can be reset to empty. This is | |
3892 | particularly useful with the .d/*.conf drop-in snippets | |
3893 | mentioned above, since this adds the ability to reset list | |
3894 | settings from vendor unit files via these drop-ins. | |
3895 | ||
3896 | * systemctl gained a new "list-dependencies" command for | |
3897 | listing the dependencies of a unit recursively. | |
3898 | ||
3899 | * Inhibitors are now honored and listed by "systemctl | |
3900 | suspend", "systemctl poweroff" (and similar) too, not only | |
3901 | GNOME. These commands will also list active sessions by | |
3902 | other users. | |
3903 | ||
3904 | * Resource limits (as exposed by the various control group | |
3905 | controllers) can now be controlled dynamically at runtime | |
3906 | for all units. More specifically, you can now use a command | |
3907 | like "systemctl set-cgroup-attr foobar.service cpu.shares | |
3908 | 2000" to alter the CPU shares a specific service gets. These | |
3909 | settings are stored persistently on disk, and thus allow the | |
3910 | administrator to easily adjust the resource usage of | |
3911 | services with a few simple commands. This dynamic resource | |
3912 | management logic is also available to other programs via the | |
3913 | bus. Almost any kernel cgroup attribute and controller is | |
3914 | supported. | |
3915 | ||
3916 | * systemd-vconsole-setup will now copy all font settings to | |
3917 | all allocated VTs, where it previously applied them only to | |
3918 | the foreground VT. | |
3919 | ||
3920 | * libsystemd-login gained the new sd_session_get_tty() API | |
3921 | call. | |
3922 | ||
3923 | * This release drops support for a few legacy or | |
3924 | distribution-specific LSB facility names when parsing init | |
3925 | scripts: $x-display-manager, $mail-transfer-agent, | |
3926 | $mail-transport-agent, $mail-transfer-agent, $smtp, | |
3927 | $null. Also, the mail-transfer-agent.target unit backing | |
3928 | this has been removed. Distributions which want to retain | |
3929 | compatibility with this should carry the burden for | |
3930 | supporting this themselves and patch support for these back | |
3931 | in, if they really need to. Also, the facilities $syslog and | |
3932 | $local_fs are now ignored, since systemd does not support | |
3933 | early-boot LSB init scripts anymore, and these facilities | |
3934 | are implied anyway for normal services. syslog.target has | |
3935 | also been removed. | |
3936 | ||
3937 | * There are new bus calls on PID1's Manager object for | |
3938 | cancelling jobs, and removing snapshot units. Previously, | |
3939 | both calls were only available on the Job and Snapshot | |
3940 | objects themselves. | |
3941 | ||
3942 | * systemd-journal-gatewayd gained SSL support. | |
3943 | ||
3944 | * The various "environment" files, such as /etc/locale.conf | |
3945 | now support continuation lines with a backslash ("\") as | |
3946 | last character in the line, similarly in style (but different) | |
3947 | to how this is supported in shells. | |
3948 | ||
3949 | * For normal user processes the _SYSTEMD_USER_UNIT= field is | |
3950 | now implicitly appended to every log entry logged. systemctl | |
3951 | has been updated to filter by this field when operating on a | |
3952 | user systemd instance. | |
3953 | ||
3954 | * nspawn will now implicitly add the CAP_AUDIT_WRITE and | |
3955 | CAP_AUDIT_CONTROL capabilities to the capabilities set for | |
3956 | the container. This makes it easier to boot unmodified | |
3957 | Fedora systems in a container, which however still requires | |
3958 | audit=0 to be passed on the kernel command line. Auditing in | |
3959 | kernel and userspace is unfortunately still too broken in | |
3960 | context of containers, hence we recommend compiling it out | |
3961 | of the kernel or using audit=0. Hopefully this will be fixed | |
3962 | one day for good in the kernel. | |
3963 | ||
3964 | * nspawn gained the new --bind= and --bind-ro= parameters to | |
3965 | bind mount specific directories from the host into the | |
3966 | container. | |
3967 | ||
3968 | * nspawn will now mount its own devpts file system instance | |
3969 | into the container, in order not to leak pty devices from | |
3970 | the host into the container. | |
3971 | ||
3972 | * systemd will now read the firmware boot time performance | |
3973 | information from the EFI variables, if the used boot loader | |
3974 | supports this, and takes it into account for boot performance | |
3975 | analysis via "systemd-analyze". This is currently supported | |
3976 | only in conjunction with Gummiboot, but could be supported | |
3977 | by other boot loaders too. For details see: | |
3978 | ||
3979 | http://www.freedesktop.org/wiki/Software/systemd/BootLoaderInterface | |
3980 | ||
3981 | * A new generator has been added that automatically mounts the | |
3982 | EFI System Partition (ESP) to /boot, if that directory | |
3983 | exists, is empty, and no other file system has been | |
3984 | configured to be mounted there. | |
3985 | ||
3986 | * logind will now send out PrepareForSleep(false) out | |
3987 | unconditionally, after coming back from suspend. This may be | |
3988 | used by applications as asynchronous notification for | |
3989 | system resume events. | |
3990 | ||
3991 | * "systemctl unlock-sessions" has been added, that allows | |
3992 | unlocking the screens of all user sessions at once, similar | |
3993 | to how "systemctl lock-sessions" already locked all users | |
3994 | sessions. This is backed by a new D-Bus call UnlockSessions(). | |
3995 | ||
3996 | * "loginctl seat-status" will now show the master device of a | |
3997 | seat. (i.e. the device of a seat that needs to be around for | |
3998 | the seat to be considered available, usually the graphics | |
3999 | card). | |
4000 | ||
4001 | * tmpfiles gained a new "X" line type, that allows | |
4002 | configuration of files and directories (with wildcards) that | |
4003 | shall be excluded from automatic cleanup ("aging"). | |
4004 | ||
4005 | * udev default rules set the device node permissions now only | |
4006 | at "add" events, and do not change them any longer with a | |
4007 | later "change" event. | |
4008 | ||
4009 | * The log messages for lid events and power/sleep keypresses | |
4010 | now carry a message ID. | |
4011 | ||
4012 | * We now have a substantially larger unit test suite, but this | |
4013 | continues to be work in progress. | |
4014 | ||
4015 | * udevadm hwdb gained a new --root= parameter to change the | |
4016 | root directory to operate relative to. | |
4017 | ||
4018 | * logind will now issue a background sync() request to the kernel | |
4019 | early at shutdown, so that dirty buffers are flushed to disk early | |
4020 | instead of at the last moment, in order to optimize shutdown | |
4021 | times a little. | |
4022 | ||
4023 | * A new bootctl tool has been added that is an interface for | |
4024 | certain boot loader operations. This is currently a preview | |
4025 | and is likely to be extended into a small mechanism daemon | |
4026 | like timedated, localed, hostnamed, and can be used by | |
4027 | graphical UIs to enumerate available boot options, and | |
4028 | request boot into firmware operations. | |
4029 | ||
4030 | * systemd-bootchart has been relicensed to LGPLv2.1+ to match | |
4031 | the rest of the package. It also has been updated to work | |
4032 | correctly in initrds. | |
4033 | ||
4034 | * Policykit previously has been runtime optional, and is now | |
4035 | also compile time optional via a configure switch. | |
4036 | ||
4037 | * systemd-analyze has been reimplemented in C. Also "systemctl | |
4038 | dot" has moved into systemd-analyze. | |
4039 | ||
4040 | * "systemctl status" with no further parameters will now print | |
4041 | the status of all active or failed units. | |
4042 | ||
4043 | * Operations such as "systemctl start" can now be executed | |
4044 | with a new mode "--irreversible" which may be used to queue | |
4045 | operations that cannot accidentally be reversed by a later | |
4046 | job queuing. This is by default used to make shutdown | |
4047 | requests more robust. | |
4048 | ||
4049 | * The Python API of systemd now gained a new module for | |
4050 | reading journal files. | |
4051 | ||
4052 | * A new tool kernel-install has been added that can install | |
4053 | kernel images according to the Boot Loader Specification: | |
4054 | ||
4055 | http://www.freedesktop.org/wiki/Specifications/BootLoaderSpec | |
4056 | ||
4057 | * Boot time console output has been improved to provide | |
4058 | animated boot time output for hanging jobs. | |
4059 | ||
4060 | * A new tool systemd-activate has been added which can be used | |
4061 | to test socket activation with, directly from the command | |
4062 | line. This should make it much easier to test and debug | |
4063 | socket activation in daemons. | |
4064 | ||
4065 | * journalctl gained a new "--reverse" (or -r) option to show | |
4066 | journal output in reverse order (i.e. newest line first). | |
4067 | ||
4068 | * journalctl gained a new "--pager-end" (or -e) option to jump | |
4069 | to immediately jump to the end of the journal in the | |
4070 | pager. This is only supported in conjunction with "less". | |
4071 | ||
4072 | * journalctl gained a new "--user-unit=" option, that works | |
4073 | similarly to "--unit=" but filters for user units rather than | |
4074 | system units. | |
4075 | ||
4076 | * A number of unit files to ease adoption of systemd in | |
4077 | initrds has been added. This moves some minimal logic from | |
4078 | the various initrd implementations into systemd proper. | |
4079 | ||
4080 | * The journal files are now owned by a new group | |
4081 | "systemd-journal", which exists specifically to allow access | |
4082 | to the journal, and nothing else. Previously, we used the | |
4083 | "adm" group for that, which however possibly covers more | |
4084 | than just journal/log file access. This new group is now | |
4085 | already used by systemd-journal-gatewayd to ensure this | |
4086 | daemon gets access to the journal files and as little else | |
4087 | as possible. Note that "make install" will also set FS ACLs | |
4088 | up for /var/log/journal to give "adm" and "wheel" read | |
4089 | access to it, in addition to "systemd-journal" which owns | |
4090 | the journal files. We recommend that packaging scripts also | |
4091 | add read access to "adm" + "wheel" to /var/log/journal, and | |
4092 | all existing/future journal files. To normal users and | |
4093 | administrators little changes, however packagers need to | |
4094 | ensure to create the "systemd-journal" system group at | |
4095 | package installation time. | |
4096 | ||
4097 | * The systemd-journal-gatewayd now runs as unprivileged user | |
4098 | systemd-journal-gateway:systemd-journal-gateway. Packaging | |
4099 | scripts need to create these system user/group at | |
4100 | installation time. | |
4101 | ||
4102 | * timedated now exposes a new boolean property CanNTP that | |
4103 | indicates whether a local NTP service is available or not. | |
4104 | ||
4105 | * systemd-detect-virt will now also detect xen PVs | |
4106 | ||
4107 | * The pstore file system is now mounted by default, if it is | |
4108 | available. | |
4109 | ||
4110 | * In addition to the SELinux and IMA policies we will now also | |
4111 | load SMACK policies at early boot. | |

4128 | CHANGES WITH 197: | |
4129 | ||
4130 | * Timer units now support calendar time events in addition to | |
4131 | monotonic time events. That means you can now trigger a unit | |
4132 | based on a calendar time specification such as "Thu,Fri | |
4133 | 2013-*-1,5 11:12:13" which refers to 11:12:13 of the first | |
4134 | or fifth day of any month of the year 2013, given that it is | |
4135 | a thursday or friday. This brings timer event support | |
4136 | considerably closer to cron's capabilities. For details on | |
4137 | the supported calendar time specification language see | |
4138 | systemd.time(7). | |
4139 | ||
4140 | * udev now supports a number of different naming policies for | |
4141 | network interfaces for predictable names, and a combination | |
4142 | of these policies is now the default. Please see this wiki | |
4143 | document for details: | |
4144 | ||
4145 | http://www.freedesktop.org/wiki/Software/systemd/PredictableNetworkInterfaceNames | |
4146 | ||
4147 | * Auke Kok's bootchart implementation has been added to the | |
4148 | systemd tree. It is an optional component that can graph the | |
4149 | boot in quite some detail. It is one of the best bootchart | |
4150 | implementations around and minimal in its code and | |
4151 | dependencies. | |
4152 | ||
4153 | * nss-myhostname has been integrated into the systemd source | |
4154 | tree. nss-myhostname guarantees that the local hostname | |
4155 | always stays resolvable via NSS. It has been a weak | |
4156 | requirement of systemd-hostnamed since a long time, and | |
4157 | since its code is actually trivial we decided to just | |
4158 | include it in systemd's source tree. It can be turned off | |
4159 | with a configure switch. | |
4160 | ||
4161 | * The read-ahead logic is now capable of properly detecting | |
4162 | whether a btrfs file system is on SSD or rotating media, in | |
4163 | order to optimize the read-ahead scheme. Previously, it was | |
4164 | only capable of detecting this on traditional file systems | |
4165 | such as ext4. | |
4166 | ||
4167 | * In udev, additional device properties are now read from the | |
4168 | IAB in addition to the OUI database. Also, Bluetooth company | |
4169 | identities are attached to the devices as well. | |
4170 | ||
4171 | * In service files %U may be used as specifier that is | |
4172 | replaced by the configured user name of the service. | |
4173 | ||
4174 | * nspawn may now be invoked without a controlling TTY. This | |
4175 | makes it suitable for invocation as its own service. This | |
4176 | may be used to set up a simple containerized server system | |
4177 | using only core OS tools. | |
4178 | ||
4179 | * systemd and nspawn can now accept socket file descriptors | |
4180 | when they are started for socket activation. This enables | |
4181 | implementation of socket activated nspawn | |
4182 | containers. i.e. think about autospawning an entire OS image | |
4183 | when the first SSH or HTTP connection is received. We expect | |
4184 | that similar functionality will also be added to libvirt-lxc | |
4185 | eventually. | |
4186 | ||
4187 | * journalctl will now suppress ANSI color codes when | |
4188 | presenting log data. | |
4189 | ||
4190 | * systemctl will no longer show control group information for | |
4191 | a unit if a the control group is empty anyway. | |
4192 | ||
4193 | * logind can now automatically suspend/hibernate/shutdown the | |
4194 | system on idle. | |
4195 | ||
4196 | * /etc/machine-info and hostnamed now also expose the chassis | |
4197 | type of the system. This can be used to determine whether | |
4198 | the local system is a laptop, desktop, handset or | |
4199 | tablet. This information may either be configured by the | |
4200 | user/vendor or is automatically determined from ACPI and DMI | |
4201 | information if possible. | |
4202 | ||
4203 | * A number of PolicyKit actions are now bound together with | |
4204 | "imply" rules. This should simplify creating UIs because | |
4205 | many actions will now authenticate similar ones as well. | |
4206 | ||
4207 | * Unit files learnt a new condition ConditionACPower= which | |
4208 | may be used to conditionalize a unit depending on whether an | |
4209 | AC power source is connected or not, of whether the system | |
4210 | is running on battery power. | |
4211 | ||
4212 | * systemctl gained a new "is-failed" verb that may be used in | |
4213 | shell scripts and suchlike to check whether a specific unit | |
4214 | is in the "failed" state. | |
4215 | ||
4216 | * The EnvironmentFile= setting in unit files now supports file | |
4217 | globbing, and can hence be used to easily read a number of | |
4218 | environment files at once. | |
4219 | ||
4220 | * systemd will no longer detect and recognize specific | |
4221 | distributions. All distribution-specific #ifdeffery has been | |
4222 | removed, systemd is now fully generic and | |
4223 | distribution-agnostic. Effectively, not too much is lost as | |
4224 | a lot of the code is still accessible via explicit configure | |
4225 | switches. However, support for some distribution specific | |
4226 | legacy configuration file formats has been dropped. We | |
4227 | recommend distributions to simply adopt the configuration | |
4228 | files everybody else uses now and convert the old | |
4229 | configuration from packaging scripts. Most distributions | |
4230 | already did that. If that's not possible or desirable, | |
4231 | distributions are welcome to forward port the specific | |
4232 | pieces of code locally from the git history. | |
4233 | ||
4234 | * When logging a message about a unit systemd will now always | |
4235 | log the unit name in the message meta data. | |
4236 | ||
4237 | * localectl will now also discover system locale data that is | |
4238 | not stored in locale archives, but directly unpacked. | |
4239 | ||
4240 | * logind will no longer unconditionally use framebuffer | |
4241 | devices as seat masters, i.e. as devices that are required | |
4242 | to be existing before a seat is considered preset. Instead, | |
4243 | it will now look for all devices that are tagged as | |
4244 | "seat-master" in udev. By default framebuffer devices will | |
4245 | be marked as such, but depending on local systems other | |
4246 | devices might be marked as well. This may be used to | |
4247 | integrate graphics cards using closed source drivers (such | |
4248 | as NVidia ones) more nicely into logind. Note however, that | |
4249 | we recommend using the open source NVidia drivers instead, | |
4250 | and no udev rules for the closed-source drivers will be | |
4251 | shipped from us upstream. | |

4267 | CHANGES WITH 196: | |
4268 | ||
4269 | * udev gained support for loading additional device properties | |
4270 | from an indexed database that is keyed by vendor/product IDs | |
4271 | and similar device identifiers. For the beginning this | |
4272 | "hwdb" is populated with data from the well-known PCI and | |
4273 | USB database, but also includes PNP, ACPI and OID data. In | |
4274 | the longer run this indexed database shall grow into | |
4275 | becoming the one central database for non-essential | |
4276 | userspace device metadata. Previously, data from the PCI/USB | |
4277 | database was only attached to select devices, since the | |
4278 | lookup was a relatively expensive operation due to O(n) time | |
4279 | complexity (with n being the number of entries in the | |
4280 | database). Since this is now O(1), we decided to add in this | |
4281 | data for all devices where this is available, by | |
4282 | default. Note that the indexed database needs to be rebuilt | |
4283 | when new data files are installed. To achieve this you need | |
4284 | to update your packaging scripts to invoke "udevadm hwdb | |
4285 | --update" after installation of hwdb data files. For | |
4286 | RPM-based distributions we introduced the new | |
4287 | %udev_hwdb_update macro for this purpose. | |
4288 | ||
4289 | * The Journal gained support for the "Message Catalog", an | |
4290 | indexed database to link up additional information with | |
4291 | journal entries. For further details please check: | |
4292 | ||
4293 | http://www.freedesktop.org/wiki/Software/systemd/catalog | |
4294 | ||
4295 | The indexed message catalog database also needs to be | |
4296 | rebuilt after installation of message catalog files. Use | |
4297 | "journalctl --update-catalog" for this. For RPM-based | |
4298 | distributions we introduced the %journal_catalog_update | |
4299 | macro for this purpose. | |
4300 | ||
4301 | * The Python Journal bindings gained support for the standard | |
4302 | Python logging framework. | |
4303 | ||
4304 | * The Journal API gained new functions for checking whether | |
4305 | the underlying file system of a journal file is capable of | |
4306 | properly reporting file change notifications, or whether | |
4307 | applications that want to reflect journal changes "live" | |
4308 | need to recheck journal files continuously in appropriate | |
4309 | time intervals. | |
4310 | ||
4311 | * It is now possible to set the "age" field for tmpfiles | |
4312 | entries to 0, indicating that files matching this entry | |
4313 | shall always be removed when the directories are cleaned up. | |
4314 | ||
4315 | * coredumpctl gained a new "gdb" verb which invokes gdb | |
4316 | right-away on the selected coredump. | |
4317 | ||
4318 | * There's now support for "hybrid sleep" on kernels that | |
4319 | support this, in addition to "suspend" and "hibernate". Use | |
4320 | "systemctl hybrid-sleep" to make use of this. | |
4321 | ||
4322 | * logind's HandleSuspendKey= setting (and related settings) | |
4323 | now gained support for a new "lock" setting to simply | |
4324 | request the screen lock on all local sessions, instead of | |
4325 | actually executing a suspend or hibernation. | |
4326 | ||
4327 | * systemd will now mount the EFI variables file system by | |
4328 | default. | |
4329 | ||
4330 | * Socket units now gained support for configuration of the | |
4331 | SMACK security label. | |
4332 | ||
4333 | * timedatectl will now output the time of the last and next | |
4334 | daylight saving change. | |
4335 | ||
4336 | * We dropped support for various legacy and distro-specific | |
4337 | concepts, such as insserv, early-boot SysV services | |
4338 | (i.e. those for non-standard runlevels such as 'b' or 'S') | |
4339 | or ArchLinux /etc/rc.conf support. We recommend the | |
4340 | distributions who still need support this to either continue | |
4341 | to maintain the necessary patches downstream, or find a | |
4342 | different solution. (Talk to us if you have questions!) | |
4343 | ||
4344 | * Various systemd components will now bypass PolicyKit checks | |
4345 | for root and otherwise handle properly if PolicyKit is not | |
4346 | found to be around. This should fix most issues for | |
4347 | PolicyKit-less systems. Quite frankly this should have been | |
4348 | this way since day one. It is absolutely our intention to | |
4349 | make systemd work fine on PolicyKit-less systems, and we | |
4350 | consider it a bug if something does not work as it should if | |
4351 | PolicyKit is not around. | |
4352 | ||
4353 | * For embedded systems it is now possible to build udev and | |
4354 | systemd without blkid and/or kmod support. | |
4355 | ||
4356 | * "systemctl switch-root" is now capable of switching root | |
4357 | more than once. I.e. in addition to transitions from the | |
4358 | initrd to the host OS it is now possible to transition to | |
4359 | further OS images from the host. This is useful to implement | |
4360 | offline updating tools. | |
4361 | ||
4362 | * Various other additions have been made to the RPM macros | |
4363 | shipped with systemd. Use %udev_rules_update() after | |
4364 | installing new udev rules files. %_udevhwdbdir, | |
4365 | %_udevrulesdir, %_journalcatalogdir, %_tmpfilesdir, | |
4366 | %_sysctldir are now available which resolve to the right | |
4367 | directories for packages to place various data files in. | |
4368 | ||
4369 | * journalctl gained the new --full switch (in addition to | |
4370 | --all, to disable ellipsation for long messages. | |

4382 | CHANGES WITH 195: | |
4383 | ||
4384 | * journalctl gained new --since= and --until= switches to | |
4385 | filter by time. It also now supports nice filtering for | |
4386 | units via --unit=/-u. | |
4387 | ||
4388 | * Type=oneshot services may use ExecReload= and do the | |
4389 | right thing. | |
4390 | ||
4391 | * The journal daemon now supports time-based rotation and | |
4392 | vacuuming, in addition to the usual disk-space based | |
4393 | rotation. | |
4394 | ||
4395 | * The journal will now index the available field values for | |
4396 | each field name. This enables clients to show pretty drop | |
4397 | downs of available match values when filtering. The bash | |
4398 | completion of journalctl has been updated | |
4399 | accordingly. journalctl gained a new switch -F to list all | |
4400 | values a certain field takes in the journal database. | |
4401 | ||
4402 | * More service events are now written as structured messages | |
4403 | to the journal, and made recognizable via message IDs. | |
4404 | ||
4405 | * The timedated, localed and hostnamed mini-services which | |
4406 | previously only provided support for changing time, locale | |
4407 | and hostname settings from graphical DEs such as GNOME now | |
4408 | also have a minimal (but very useful) text-based client | |
4409 | utility each. This is probably the nicest way to changing | |
4410 | these settings from the command line now, especially since | |
4411 | it lists available options and is fully integrated with bash | |
4412 | completion. | |
4413 | ||
4414 | * There's now a new tool "systemd-coredumpctl" to list and | |
4415 | extract coredumps from the journal. | |
4416 | ||
4417 | * We now install a README each in /var/log/ and | |
4418 | /etc/rc.d/init.d explaining where the system logs and init | |
4419 | scripts went. This hopefully should help folks who go to | |
4420 | that dirs and look into the otherwise now empty void and | |
4421 | scratch their heads. | |
4422 | ||
4423 | * When user-services are invoked (by systemd --user) the | |
4424 | $MANAGERPID env var is set to the PID of systemd. | |
4425 | ||
4426 | * SIGRTMIN+24 when sent to a --user instance will now result | |
4427 | in immediate termination of systemd. | |
4428 | ||
4429 | * gatewayd received numerous feature additions such as a | |
4430 | "follow" mode, for live syncing and filtering. | |
4431 | ||
4432 | * browse.html now allows filtering and showing detailed | |
4433 | information on specific entries. Keyboard navigation and | |
4434 | mouse screen support has been added. | |
4435 | ||
4436 | * gatewayd/journalctl now supports HTML5/JSON | |
4437 | Server-Sent-Events as output. | |
4438 | ||
4439 | * The SysV init script compatibility logic will now | |
4440 | heuristically determine whether a script supports the | |
4441 | "reload" verb, and only then make this available as | |
4442 | "systemctl reload". | |
4443 | ||
4444 | * "systemctl status --follow" has been removed, use "journalctl | |
4445 | -u" instead. | |
4446 | ||
4447 | * journald.conf's RuntimeMinSize=, PersistentMinSize= settings | |
4448 | have been removed since they are hardly useful to be | |
4449 | configured. | |
4450 | ||
4451 | * And I'd like to take the opportunity to specifically mention | |
4452 | Zbigniew for his great contributions. Zbigniew, you rock! | |

4462 | CHANGES WITH 194: | |
4463 | ||
4464 | * If /etc/vconsole.conf is non-existent or empty we will no | |
4465 | longer load any console font or key map at boot by | |
4466 | default. Instead the kernel defaults will be left | |
4467 | intact. This is definitely the right thing to do, as no | |
4468 | configuration should mean no configuration, and hard-coding | |
4469 | font names that are different on all archs is probably a bad | |
4470 | idea. Also, the kernel default key map and font should be | |
4471 | good enough for most cases anyway, and mostly identical to | |
4472 | the userspace fonts/key maps we previously overloaded them | |
4473 | with. If distributions want to continue to default to a | |
4474 | non-kernel font or key map they should ship a default | |
4475 | /etc/vconsole.conf with the appropriate contents. | |

4481 | CHANGES WITH 193: | |
4482 | ||
4483 | * journalctl gained a new --cursor= switch to show entries | |
4484 | starting from the specified location in the journal. | |
4485 | ||
4486 | * We now enforce a size limit on journal entry fields exported | |
4487 | with "-o json" in journalctl. Fields larger than 4K will be | |
4488 | assigned null. This can be turned off with --all. | |
4489 | ||
4490 | * An (optional) journal gateway daemon is now available as | |
4491 | "systemd-journal-gatewayd.service". This service provides | |
4492 | access to the journal via HTTP and JSON. This functionality | |
4493 | will be used to implement live log synchronization in both | |
4494 | pull and push modes, but has various other users too, such | |
4495 | as easy log access for debugging of embedded devices. Right | |
4496 | now it is already useful to retrieve the journal via HTTP: | |
4497 | ||
4498 | # systemctl start systemd-journal-gatewayd.service | |
4499 | # wget http://localhost:19531/entries | |
4500 | ||
4501 | This will download the journal contents in a | |
4502 | /var/log/messages compatible format. The same as JSON: | |
4503 | ||
4504 | # curl -H"Accept: application/json" http://localhost:19531/entries | |
4505 | ||
4506 | This service is also accessible via a web browser where a | |
4507 | single static HTML5 app is served that uses the JSON logic | |
4508 | to enable the user to do some basic browsing of the | |
4509 | journal. This will be extended later on. Here's an example | |
4510 | screenshot of this app in its current state: | |

4517 | CHANGES WITH 192: | |
4518 | ||
4519 | * The bash completion logic is now available for journalctl | |
4520 | too. | |
4521 | ||
4522 | * We do not mount the "cpuset" controller anymore together with | |
4523 | "cpu" and "cpuacct", as "cpuset" groups generally cannot be | |
4524 | started if no parameters are assigned to it. "cpuset" hence | |
4525 | broke code that assumed it it could create "cpu" groups and | |
4526 | just start them. | |
4527 | ||
4528 | * journalctl -f will now subscribe to terminal size changes, | |
4529 | and line break accordingly. | |

4533 | ||
4534 | CHANGES WITH 191: | |
4535 | ||
4536 | * nspawn will now create a symlink /etc/localtime in the | |
4537 | container environment, copying the host's timezone | |
4538 | setting. Previously this has been done via a bind mount, but | |
4539 | since symlinks cannot be bind mounted this has now been | |
4540 | changed to create/update the appropriate symlink. | |
4541 | ||
4542 | * journalctl -n's line number argument is now optional, and | |
4543 | will default to 10 if omitted. | |
4544 | ||
4545 | * journald will now log the maximum size the journal files may | |
4546 | take up on disk. This is particularly useful if the default | |
4547 | built-in logic of determining this parameter from the file | |
4548 | system size is used. Use "systemctl status | |
4549 | systemd-journald.service" to see this information. | |
4550 | ||
4551 | * The multi-seat X wrapper tool has been stripped down. As X | |
4552 | is now capable of enumerating graphics devices via udev in a | |
4553 | seat-aware way the wrapper is not strictly necessary | |
4554 | anymore. A stripped down temporary stop-gap is still shipped | |
4555 | until the upstream display managers have been updated to | |
4556 | fully support the new X logic. Expect this wrapper to be | |
4557 | removed entirely in one of the next releases. | |
4558 | ||
4559 | * HandleSleepKey= in logind.conf has been split up into | |
4560 | HandleSuspendKey= and HandleHibernateKey=. The old setting | |
4561 | is not available anymore. X11 and the kernel are | |
4562 | distinguishing between these keys and we should too. This | |
4563 | also means the inhibition lock for these keys has been split | |
4564 | into two. | |

4569 | CHANGES WITH 190: | |
4570 | ||
4571 | * Whenever a unit changes state we will now log this to the | |
4572 | journal and show along the unit's own log output in | |
4573 | "systemctl status". | |
4574 | ||
4575 | * ConditionPathIsMountPoint= can now properly detect bind | |
4576 | mount points too. (Previously, a bind mount of one file | |
4577 | system to another place in the same file system could not be | |
4578 | detected as mount, since they shared struct stat's st_dev | |
4579 | field.) | |
4580 | ||
4581 | * We will now mount the cgroup controllers cpu, cpuacct, | |
4582 | cpuset and the controllers net_cls, net_prio together by | |
4583 | default. | |
4584 | ||
4585 | * nspawn containers will now have a virtualized boot | |
4586 | ID. (i.e. /proc/sys/kernel/random/boot_id is now mounted | |
4587 | over with a randomized ID at container initialization). This | |
4588 | has the effect of making "journalctl -b" do the right thing | |
4589 | in a container. | |
4590 | ||
4591 | * The JSON output journal serialization has been updated not | |
4592 | to generate "endless" list objects anymore, but rather one | |
4593 | JSON object per line. This is more in line how most JSON | |
4594 | parsers expect JSON objects. The new output mode | |
4595 | "json-pretty" has been added to provide similar output, but | |
4596 | neatly aligned for readability by humans. | |
4597 | ||
4598 | * We dropped all explicit sync() invocations in the shutdown | |
4599 | code. The kernel does this implicitly anyway in the kernel | |
4600 | reboot() syscall. halt(8)'s -n option is now a compatibility | |
4601 | no-op. | |
4602 | ||
4603 | * We now support virtualized reboot() in containers, as | |
4604 | supported by newer kernels. We will fall back to exit() if | |
4605 | CAP_SYS_REBOOT is not available to the container. Also, | |
4606 | nspawn makes use of this now and will actually reboot the | |
4607 | container if the containerized OS asks for that. | |
4608 | ||
4609 | * journalctl will only show local log output by default | |
4610 | now. Use --merge (-m) to show remote log output, too. | |
4611 | ||
4612 | * libsystemd-journal gained the new sd_journal_get_usage() | |
4613 | call to determine the current disk usage of all journal | |
4614 | files. This is exposed in the new "journalctl --disk-usage" | |
4615 | command. | |
4616 | ||
4617 | * journald gained a new configuration setting SplitMode= in | |
4618 | journald.conf which may be used to control how user journals | |
4619 | are split off. See journald.conf(5) for details. | |
4620 | ||
4621 | * A new condition type ConditionFileNotEmpty= has been added. | |
4622 | ||
4623 | * tmpfiles' "w" lines now support file globbing, to write | |
4624 | multiple files at once. | |
4625 | ||
4626 | * We added Python bindings for the journal submission | |
4627 | APIs. More Python APIs for a number of selected APIs will | |
4628 | likely follow. Note that we intend to add native bindings | |
4629 | only for the Python language, as we consider it common | |
4630 | enough to deserve bindings shipped within systemd. There are | |
4631 | various projects outside of systemd that provide bindings | |
4632 | for languages such as PHP or Lua. | |
4633 | ||
4634 | * Many conditions will now resolve specifiers such as %i. In | |
4635 | addition, PathChanged= and related directives of .path units | |
4636 | now support specifiers as well. | |
4637 | ||
4638 | * There's now a new RPM macro definition for the system preset | |
4639 | dir: %_presetdir. | |
4640 | ||
4641 | * journald will now warn if it ca not forward a message to the | |
4642 | syslog daemon because its socket is full. | |
4643 | ||
4644 | * timedated will no longer write or process /etc/timezone, | |
4645 | except on Debian. As we do not support late mounted /usr | |
4646 | anymore /etc/localtime always being a symlink is now safe, | |
4647 | and hence the information in /etc/timezone is not necessary | |
4648 | anymore. | |
4649 | ||
4650 | * logind will now always reserve one VT for a text getty (VT6 | |
4651 | by default). Previously if more than 6 X sessions where | |
4652 | started they took up all the VTs with auto-spawned gettys, | |
4653 | so that no text gettys were available anymore. | |
4654 | ||
4655 | * udev will now automatically inform the btrfs kernel logic | |
4656 | about btrfs RAID components showing up. This should make | |
4657 | simple hotplug based btrfs RAID assembly work. | |
4658 | ||
4659 | * PID 1 will now increase its RLIMIT_NOFILE to 64K by default | |
4660 | (but not for its children which will stay at the kernel | |
4661 | default). This should allow setups with a lot more listening | |
4662 | sockets. | |
4663 | ||
4664 | * systemd will now always pass the configured timezone to the | |
4665 | kernel at boot. timedated will do the same when the timezone | |
4666 | is changed. | |
4667 | ||
4668 | * logind's inhibition logic has been updated. By default, | |
4669 | logind will now handle the lid switch, the power and sleep | |
4670 | keys all the time, even in graphical sessions. If DEs want | |
4671 | to handle these events on their own they should take the new | |
4672 | handle-power-key, handle-sleep-key and handle-lid-switch | |
4673 | inhibitors during their runtime. A simple way to achieve | |
4674 | that is to invoke the DE wrapped in an invocation of: | |
4675 | ||
4676 | systemd-inhibit --what=handle-power-key:handle-sleep-key:handle-lid-switch ... | |
4677 | ||
4678 | * Access to unit operations is now checked via SELinux taking | |
4679 | the unit file label and client process label into account. | |
4680 | ||
4681 | * systemd will now notify the administrator in the journal | |
4682 | when he over-mounts a non-empty directory. | |
4683 | ||
4684 | * There are new specifiers that are resolved in unit files, | |
4685 | for the host name (%H), the machine ID (%m) and the boot ID | |
4686 | (%b). | |

4696 | CHANGES WITH 189: | |
4697 | ||
4698 | * Support for reading structured kernel messages from | |
4699 | /dev/kmsg has now been added and is enabled by default. | |
4700 | ||
4701 | * Support for reading kernel messages from /proc/kmsg has now | |
4702 | been removed. If you want kernel messages in the journal | |
4703 | make sure to run a recent kernel (>= 3.5) that supports | |
4704 | reading structured messages from /dev/kmsg (see | |
4705 | above). /proc/kmsg is now exclusive property of classic | |
4706 | syslog daemons again. | |
4707 | ||
4708 | * The libudev API gained the new | |
4709 | udev_device_new_from_device_id() call. | |
4710 | ||
4711 | * The logic for file system namespace (ReadOnlyDirectory=, | |
4712 | ReadWriteDirectoy=, PrivateTmp=) has been reworked not to | |
4713 | require pivot_root() anymore. This means fewer temporary | |
4714 | directories are created below /tmp for this feature. | |
4715 | ||
4716 | * nspawn containers will now see and receive all submounts | |
4717 | made on the host OS below the root file system of the | |
4718 | container. | |
4719 | ||
4720 | * Forward Secure Sealing is now supported for Journal files, | |
4721 | which provide cryptographical sealing of journal files so | |
4722 | that attackers cannot alter log history anymore without this | |
4723 | being detectable. Lennart will soon post a blog story about | |
4724 | this explaining it in more detail. | |
4725 | ||
4726 | * There are two new service settings RestartPreventExitStatus= | |
4727 | and SuccessExitStatus= which allow configuration of exit | |
4728 | status (exit code or signal) which will be excepted from the | |
4729 | restart logic, resp. consider successful. | |
4730 | ||
4731 | * journalctl gained the new --verify switch that can be used | |
4732 | to check the integrity of the structure of journal files and | |
4733 | (if Forward Secure Sealing is enabled) the contents of | |
4734 | journal files. | |
4735 | ||
4736 | * nspawn containers will now be run with /dev/stdin, /dev/fd/ | |
4737 | and similar symlinks pre-created. This makes running shells | |
4738 | as container init process a lot more fun. | |
4739 | ||
4740 | * The fstab support can now handle PARTUUID= and PARTLABEL= | |
4741 | entries. | |
4742 | ||
4743 | * A new ConditionHost= condition has been added to match | |
4744 | against the hostname (with globs) and machine ID. This is | |
4745 | useful for clusters where a single OS image is used to | |
4746 | provision a large number of hosts which shall run slightly | |
4747 | different sets of services. | |
4748 | ||
4749 | * Services which hit the restart limit will now be placed in a | |
4750 | failure state. | |

4755 | ||
4756 | CHANGES WITH 188: | |
4757 | ||
4758 | * When running in --user mode systemd will now become a | |
4759 | subreaper (PR_SET_CHILD_SUBREAPER). This should make the ps | |
4760 | tree a lot more organized. | |
4761 | ||
4762 | * A new PartOf= unit dependency type has been introduced that | |
4763 | may be used to group services in a natural way. | |
4764 | ||
4765 | * "systemctl enable" may now be used to enable instances of | |
4766 | services. | |
4767 | ||
4768 | * journalctl now prints error log levels in red, and | |
4769 | warning/notice log levels in bright white. It also supports | |
4770 | filtering by log level now. | |
4771 | ||
4772 | * cgtop gained a new -n switch (similar to top), to configure | |
4773 | the maximum number of iterations to run for. It also gained | |
4774 | -b, to run in batch mode (accepting no input). | |
4775 | ||
4776 | * The suffix ".service" may now be omitted on most systemctl | |
4777 | command lines involving service unit names. | |
4778 | ||
4779 | * There's a new bus call in logind to lock all sessions, as | |
4780 | well as a loginctl verb for it "lock-sessions". | |
4781 | ||
4782 | * libsystemd-logind.so gained a new call sd_journal_perror() | |
4783 | that works similar to libc perror() but logs to the journal | |
4784 | and encodes structured information about the error number. | |
4785 | ||
4786 | * /etc/crypttab entries now understand the new keyfile-size= | |
4787 | option. | |
4788 | ||
4789 | * shutdown(8) now can send a (configurable) wall message when | |
4790 | a shutdown is cancelled. | |
4791 | ||
4792 | * The mount propagation mode for the root file system will now | |
4793 | default to "shared", which is useful to make containers work | |
4794 | nicely out-of-the-box so that they receive new mounts from | |
4795 | the host. This can be undone locally by running "mount | |
4796 | --make-rprivate /" if needed. | |
4797 | ||
4798 | * The prefdm.service file has been removed. Distributions | |
4799 | should maintain this unit downstream if they intend to keep | |
4800 | it around. However, we recommend writing normal unit files | |
4801 | for display managers instead. | |
4802 | ||
4803 | * Since systemd is a crucial part of the OS we will now | |
4804 | default to a number of compiler switches that improve | |
4805 | security (hardening) such as read-only relocations, stack | |
4806 | protection, and suchlike. | |
4807 | ||
4808 | * The TimeoutSec= setting for services is now split into | |
4809 | TimeoutStartSec= and TimeoutStopSec= to allow configuration | |
4810 | of individual time outs for the start and the stop phase of | |
4811 | the service. | |

4819 | ||
4820 | CHANGES WITH 187: | |
4821 | ||
4822 | * The journal and id128 C APIs are now fully documented as man | |
4823 | pages. | |
4824 | ||
4825 | * Extra safety checks have been added when transitioning from | |
4826 | the initial RAM disk to the main system to avoid accidental | |
4827 | data loss. | |
4828 | ||
4829 | * /etc/crypttab entries now understand the new keyfile-offset= | |
4830 | option. | |
4831 | ||
4832 | * systemctl -t can now be used to filter by unit load state. | |
4833 | ||
4834 | * The journal C API gained the new sd_journal_wait() call to | |
4835 | make writing synchronous journal clients easier. | |
4836 | ||
4837 | * journalctl gained the new -D switch to show journals from a | |
4838 | specific directory. | |
4839 | ||
4840 | * journalctl now displays a special marker between log | |
4841 | messages of two different boots. | |
4842 | ||
4843 | * The journal is now explicitly flushed to /var via a service | |
4844 | systemd-journal-flush.service, rather than implicitly simply | |
4845 | by seeing /var/log/journal to be writable. | |
4846 | ||
4847 | * journalctl (and the journal C APIs) can now match for much | |
4848 | more complex expressions, with alternatives and | |
4849 | disjunctions. | |
4850 | ||
4851 | * When transitioning from the initial RAM disk to the main | |
4852 | system we will now kill all processes in a killing spree to | |
4853 | ensure no processes stay around by accident. | |
4854 | ||
4855 | * Three new specifiers may be used in unit files: %u, %h, %s | |
4856 | resolve to the user name, user home directory resp. user | |
4857 | shell. This is useful for running systemd user instances. | |
4858 | ||
4859 | * We now automatically rotate journal files if their data | |
4860 | object hash table gets a fill level > 75%. We also size the | |
4861 | hash table based on the configured maximum file size. This | |
4862 | together should lower hash collisions drastically and thus | |
4863 | speed things up a bit. | |
4864 | ||
4865 | * journalctl gained the new "--header" switch to introspect | |
4866 | header data of journal files. | |
4867 | ||
4868 | * A new setting SystemCallFilters= has been added to services | |
4869 | which may be used to apply blacklists or whitelists to | |
4870 | system calls. This is based on SECCOMP Mode 2 of Linux 3.5. | |
4871 | ||
4872 | * nspawn gained a new --link-journal= switch (and quicker: -j) | |
4873 | to link the container journal with the host. This makes it | |
4874 | very easy to centralize log viewing on the host for all | |
4875 | guests while still keeping the journal files separated. | |
4876 | ||
4877 | * Many bugfixes and optimizations | |

4883 | ||
4884 | CHANGES WITH 186: | |
4885 | ||
4886 | * Several tools now understand kernel command line arguments, | |
4887 | which are only read when run in an initial RAM disk. They | |
4888 | usually follow closely their normal counterparts, but are | |
4889 | prefixed with rd. | |
4890 | ||
4891 | * There's a new tool to analyze the readahead files that are | |
4892 | automatically generated at boot. Use: | |
4893 | ||
4894 | /usr/lib/systemd/systemd-readahead analyze /.readahead | |
4895 | ||
4896 | * We now provide an early debug shell on tty9 if this enabled. Use: | |
4897 | ||
4898 | systemctl enable debug-shell.service | |
4899 | ||
4900 | * All plymouth related units have been moved into the Plymouth | |
4901 | package. Please make sure to upgrade your Plymouth version | |
4902 | as well. | |
4903 | ||
4904 | * systemd-tmpfiles now supports getting passed the basename of | |
4905 | a configuration file only, in which case it will look for it | |
4906 | in all appropriate directories automatically. | |
4907 | ||
4908 | * udevadm info now takes a /dev or /sys path as argument, and | |
4909 | does the right thing. Example: | |
4910 | ||
4911 | udevadm info /dev/sda | |
4912 | udevadm info /sys/class/block/sda | |
4913 | ||
4914 | * systemctl now prints a warning if a unit is stopped but a | |
4915 | unit that might trigger it continues to run. Example: a | |
4916 | service is stopped but the socket that activates it is left | |
4917 | running. | |
4918 | ||
4919 | * "systemctl status" will now mention if the log output was | |
4920 | shortened due to rotation since a service has been started. | |
4921 | ||
4922 | * The journal API now exposes functions to determine the | |
4923 | "cutoff" times due to rotation. | |
4924 | ||
4925 | * journald now understands SIGUSR1 and SIGUSR2 for triggering | |
4926 | immediately flushing of runtime logs to /var if possible, | |
4927 | resp. for triggering immediate rotation of the journal | |
4928 | files. | |
4929 | ||
4930 | * It is now considered an error if a service is attempted to | |
4931 | be stopped that is not loaded. | |
4932 | ||
4933 | * XDG_RUNTIME_DIR now uses numeric UIDs instead of usernames. | |
4934 | ||
4935 | * systemd-analyze now supports Python 3 | |
4936 | ||
4937 | * tmpfiles now supports cleaning up directories via aging | |
4938 | where the first level dirs are always kept around but | |
4939 | directories beneath it automatically aged. This is enabled | |
4940 | by prefixing the age field with '~'. | |
4941 | ||
4942 | * Seat objects now expose CanGraphical, CanTTY properties | |
4943 | which is required to deal with very fast bootups where the | |
4944 | display manager might be running before the graphics drivers | |
4945 | completed initialization. | |
4946 | ||
4947 | * Seat objects now expose a State property. | |
4948 | ||
4949 | * We now include RPM macros for service enabling/disabling | |
4950 | based on the preset logic. We recommend RPM based | |
4951 | distributions to make use of these macros if possible. This | |
4952 | makes it simpler to reuse RPM spec files across | |
4953 | distributions. | |
4954 | ||
4955 | * We now make sure that the collected systemd unit name is | |
4956 | always valid when services log to the journal via | |
4957 | STDOUT/STDERR. | |
4958 | ||
4959 | * There's a new man page kernel-command-line(7) detailing all | |
4960 | command line options we understand. | |
4961 | ||
4962 | * The fstab generator may now be disabled at boot by passing | |
4963 | fstab=0 on the kernel command line. | |
4964 | ||
4965 | * A new kernel command line option modules-load= is now understood | |
4966 | to load a specific kernel module statically, early at boot. | |
4967 | ||
4968 | * Unit names specified on the systemctl command line are now | |
4969 | automatically escaped as needed. Also, if file system or | |
4970 | device paths are specified they are automatically turned | |
4971 | into the appropriate mount or device unit names. Example: | |
4972 | ||
4973 | systemctl status /home | |
4974 | systemctl status /dev/sda | |
4975 | ||
4976 | * The SysVConsole= configuration option has been removed from | |
4977 | system.conf parsing. | |
4978 | ||
4979 | * The SysV search path is no longer exported on the D-Bus | |
4980 | Manager object. | |
4981 | ||
4982 | * The Names= option is been removed from unit file parsing. | |
4983 | ||
4984 | * There's a new man page bootup(7) detailing the boot process. | |
4985 | ||
4986 | * Every unit and every generator we ship with systemd now | |
4987 | comes with full documentation. The self-explanatory boot is | |
4988 | complete. | |
4989 | ||
4990 | * A couple of services gained "systemd-" prefixes in their | |
4991 | name if they wrap systemd code, rather than only external | |
4992 | code. Among them fsck@.service which is now | |
4993 | systemd-fsck@.service. | |
4994 | ||
4995 | * The HaveWatchdog property has been removed from the D-Bus | |
4996 | Manager object. | |
4997 | ||
4998 | * systemd.confirm_spawn= on the kernel command line should now | |
4999 | work sensibly. | |
5000 | ||
5001 | * There's a new man page crypttab(5) which details all options | |
5002 | we actually understand. | |
5003 | ||
5004 | * systemd-nspawn gained a new --capability= switch to pass | |
5005 | additional capabilities to the container. | |
5006 | ||
5007 | * timedated will now read known NTP implementation unit names | |
5008 | from /usr/lib/systemd/ntp-units.d/*.list, | |
5009 | systemd-timedated-ntp.target has been removed. | |
5010 | ||
5011 | * journalctl gained a new switch "-b" that lists log data of | |
5012 | the current boot only. | |
5013 | ||
5014 | * The notify socket is in the abstract namespace again, in | |
5015 | order to support daemons which chroot() at start-up. | |
5016 | ||
5017 | * There is a new Storage= configuration option for journald | |
5018 | which allows configuration of where log data should go. This | |
5019 | also provides a way to disable journal logging entirely, so | |
5020 | that data collected is only forwarded to the console, the | |
5021 | kernel log buffer or another syslog implementation. | |
5022 | ||
5023 | * Many bugfixes and optimizations | |

5030 | CHANGES WITH 185: | |
5031 | ||
5032 | * "systemctl help <unit>" now shows the man page if one is | |
5033 | available. | |
5034 | ||
5035 | * Several new man pages have been added. | |
5036 | ||
5037 | * MaxLevelStore=, MaxLevelSyslog=, MaxLevelKMsg=, | |
5038 | MaxLevelConsole= can now be specified in | |
5039 | journald.conf. These options allow reducing the amount of | |
5040 | data stored on disk or forwarded by the log level. | |
5041 | ||
5042 | * TimerSlackNSec= can now be specified in system.conf for | |
5043 | PID1. This allows system-wide power savings. | |

5049 | CHANGES WITH 184: | |
5050 | ||
5051 | * logind is now capable of (optionally) handling power and | |
5052 | sleep keys as well as the lid switch. | |
5053 | ||
5054 | * journalctl now understands the syntax "journalctl | |
5055 | /usr/bin/avahi-daemon" to get all log output of a specific | |
5056 | daemon. | |
5057 | ||
5058 | * CapabilityBoundingSet= in system.conf now also influences | |
5059 | the capability bound set of usermode helpers of the kernel. | |

5065 | ||
5066 | CHANGES WITH 183: | |
5067 | ||
5068 | * Note that we skipped 139 releases here in order to set the | |
5069 | new version to something that is greater than both udev's | |
5070 | and systemd's most recent version number. | |
5071 | ||
5072 | * udev: all udev sources are merged into the systemd source tree now. | |
5073 | All future udev development will happen in the systemd tree. It | |
5074 | is still fully supported to use the udev daemon and tools without | |
5075 | systemd running, like in initramfs or other init systems. Building | |
5076 | udev though, will require the *build* of the systemd tree, but | |
5077 | udev can be properly *run* without systemd. | |
5078 | ||
5079 | * udev: /lib/udev/devices/ are not read anymore; systemd-tmpfiles | |
5080 | should be used to create dead device nodes as workarounds for broken | |
5081 | subsystems. | |
5082 | ||
5083 | * udev: RUN+="socket:..." and udev_monitor_new_from_socket() is | |
5084 | no longer supported. udev_monitor_new_from_netlink() needs to be | |
5085 | used to subscribe to events. | |
5086 | ||
5087 | * udev: when udevd is started by systemd, processes which are left | |
5088 | behind by forking them off of udev rules, are unconditionally cleaned | |
5089 | up and killed now after the event handling has finished. Services or | |
5090 | daemons must be started as systemd services. Services can be | |
5091 | pulled-in by udev to get started, but they can no longer be directly | |
5092 | forked by udev rules. | |
5093 | ||
5094 | * udev: the daemon binary is called systemd-udevd now and installed | |
5095 | in /usr/lib/systemd/. Standalone builds or non-systemd systems need | |
5096 | to adapt to that, create symlink, or rename the binary after building | |
5097 | it. | |
5098 | ||
5099 | * libudev no longer provides these symbols: | |
5100 | udev_monitor_from_socket() | |
5101 | udev_queue_get_failed_list_entry() | |
5102 | udev_get_{dev,sys,run}_path() | |
5103 | The versions number was bumped and symbol versioning introduced. | |
5104 | ||
5105 | * systemd-loginctl and systemd-journalctl have been renamed | |
5106 | to loginctl and journalctl to match systemctl. | |
5107 | ||
5108 | * The config files: /etc/systemd/systemd-logind.conf and | |
5109 | /etc/systemd/systemd-journald.conf have been renamed to | |
5110 | logind.conf and journald.conf. Package updates should rename | |
5111 | the files to the new names on upgrade. | |
5112 | ||
5113 | * For almost all files the license is now LGPL2.1+, changed | |
5114 | from the previous GPL2.0+. Exceptions are some minor stuff | |
5115 | of udev (which will be changed to LGPL2.1 eventually, too), | |
5116 | and the MIT licensed sd-daemon.[ch] library that is suitable | |
5117 | to be used as drop-in files. | |
5118 | ||
5119 | * systemd and logind now handle system sleep states, in | |
5120 | particular suspending and hibernating. | |
5121 | ||
5122 | * logind now implements a sleep/shutdown/idle inhibiting logic | |
5123 | suitable for a variety of uses. Soonishly Lennart will blog | |
5124 | about this in more detail. | |
5125 | ||
5126 | * var-run.mount and var-lock.mount are no longer provided | |
5127 | (which prevously bind mounted these directories to their new | |
5128 | places). Distributions which have not converted these | |
5129 | directories to symlinks should consider stealing these files | |
5130 | from git history and add them downstream. | |
5131 | ||
5132 | * We introduced the Documentation= field for units and added | |
5133 | this to all our shipped units. This is useful to make it | |
5134 | easier to explore the boot and the purpose of the various | |
5135 | units. | |
5136 | ||
5137 | * All smaller setup units (such as | |
5138 | systemd-vconsole-setup.service) now detect properly if they | |
5139 | are run in a container and are skipped when | |
5140 | appropriate. This guarantees an entirely noise-free boot in | |
5141 | Linux container environments such as systemd-nspawn. | |
5142 | ||
5143 | * A framework for implementing offline system updates is now | |
5144 | integrated, for details see: | |
5145 | http://freedesktop.org/wiki/Software/systemd/SystemUpdates | |
5146 | ||
5147 | * A new service type Type=idle is available now which helps us | |
5148 | avoiding ugly interleaving of getty output and boot status | |
5149 | messages. | |
5150 | ||
5151 | * There's now a system-wide CapabilityBoundingSet= option to | |
5152 | globally reduce the set of capabilities for the | |
5153 | system. This is useful to drop CAP_SYS_MKNOD, CAP_SYS_RAWIO, | |
5154 | CAP_NET_RAW, CAP_SYS_MODULE, CAP_SYS_TIME, CAP_SYS_PTRACE or | |
5155 | even CAP_NET_ADMIN system-wide for secure systems. | |
5156 | ||
5157 | * There are now system-wide DefaultLimitXXX= options to | |
5158 | globally change the defaults of the various resource limits | |
5159 | for all units started by PID 1. | |
5160 | ||
5161 | * Harald Hoyer's systemd test suite has been integrated into | |
5162 | systemd which allows easy testing of systemd builds in qemu | |
5163 | and nspawn. (This is really awesome! Ask us for details!) | |
5164 | ||
5165 | * The fstab parser is now implemented as generator, not inside | |
5166 | of PID 1 anymore. | |
5167 | ||
5168 | * systemctl will now warn you if .mount units generated from | |
5169 | /etc/fstab are out of date due to changes in fstab that | |
5170 | have not been read by systemd yet. | |
5171 | ||
5172 | * systemd is now suitable for usage in initrds. Dracut has | |
5173 | already been updated to make use of this. With this in place | |
5174 | initrds get a slight bit faster but primarily are much | |
5175 | easier to introspect and debug since "systemctl status" in | |
5176 | the host system can be used to introspect initrd services, | |
5177 | and the journal from the initrd is kept around too. | |
5178 | ||
5179 | * systemd-delta has been added, a tool to explore differences | |
5180 | between user/admin configuration and vendor defaults. | |
5181 | ||
5182 | * PrivateTmp= now affects both /tmp and /var/tmp. | |
5183 | ||
5184 | * Boot time status messages are now much prettier and feature | |
5185 | proper english language. Booting up systemd has never been | |
5186 | so sexy. | |
5187 | ||
5188 | * Read-ahead pack files now include the inode number of all | |
5189 | files to pre-cache. When the inode changes the pre-caching | |
5190 | is not attempted. This should be nicer to deal with updated | |
5191 | packages which might result in changes of read-ahead | |
5192 | patterns. | |
5193 | ||
5194 | * We now temporaritly lower the kernel's read_ahead_kb variable | |
5195 | when collecting read-ahead data to ensure the kernel's | |
5196 | built-in read-ahead does not add noise to our measurements | |
5197 | of necessary blocks to pre-cache. | |
5198 | ||
5199 | * There's now RequiresMountsFor= to add automatic dependencies | |
5200 | for all mounts necessary for a specific file system path. | |
5201 | ||
5202 | * MountAuto= and SwapAuto= have been removed from | |
5203 | system.conf. Mounting file systems at boot has to take place | |
5204 | in systemd now. | |
5205 | ||
5206 | * nspawn now learned a new switch --uuid= to set the machine | |
5207 | ID on the command line. | |
5208 | ||
5209 | * nspawn now learned the -b switch to automatically search | |
5210 | for an init system. | |
5211 | ||
5212 | * vt102 is now the default TERM for serial TTYs, upgraded from | |
5213 | vt100. | |
5214 | ||
5215 | * systemd-logind now works on VT-less systems. | |
5216 | ||
5217 | * The build tree has been reorganized. The individual | |
5218 | components now have directories of their own. | |
5219 | ||
5220 | * A new condition type ConditionPathIsReadWrite= is now available. | |
5221 | ||
5222 | * nspawn learned the new -C switch to create cgroups for the | |
5223 | container in other hierarchies. | |
5224 | ||
5225 | * We now have support for hardware watchdogs, configurable in | |
5226 | system.conf. | |
5227 | ||
5228 | * The scheduled shutdown logic now has a public API. | |
5229 | ||
5230 | * We now mount /tmp as tmpfs by default, but this can be | |
5231 | masked and /etc/fstab can override it. | |
5232 | ||
5233 | * Since udisks does not make use of /media anymore we are not | |
5234 | mounting a tmpfs on it anymore. | |
5235 | ||
5236 | * journalctl gained a new --local switch to only interleave | |
5237 | locally generated journal files. | |
5238 | ||
5239 | * We can now load the IMA policy at boot automatically. | |
5240 | ||
5241 | * The GTK tools have been split off into a systemd-ui. | |

5254 | CHANGES WITH 44: | |
5255 | ||
5256 | * This is mostly a bugfix release | |
5257 | ||
5258 | * Support optional initialization of the machine ID from the | |
5259 | KVM or container configured UUID. | |
5260 | ||
5261 | * Support immediate reboots with "systemctl reboot -ff" | |
5262 | ||
5263 | * Show /etc/os-release data in systemd-analyze output | |
5264 | ||
5265 | * Many bugfixes for the journal, including endianness fixes and | |
5266 | ensuring that disk space enforcement works | |
5267 | ||
5268 | * sd-login.h is C++ comptaible again | |
5269 | ||
5270 | * Extend the /etc/os-release format on request of the Debian | |
5271 | folks | |
5272 | ||
5273 | * We now refuse non-UTF8 strings used in various configuration | |
5274 | and unit files. This is done to ensure we do not pass invalid | |
5275 | data over D-Bus or expose it elsewhere. | |
5276 | ||
5277 | * Register Mimo USB Screens as suitable for automatic seat | |
5278 | configuration | |
5279 | ||
5280 | * Read SELinux client context from journal clients in a race | |
5281 | free fashion | |
5282 | ||
5283 | * Reorder configuration file lookup order. /etc now always | |
5284 | overrides /run in order to allow the administrator to always | |
5285 | and unconditionally override vendor supplied or | |
5286 | automatically generated data. | |
5287 | ||
5288 | * The various user visible bits of the journal now have man | |
5289 | pages. We still lack man pages for the journal API calls | |
5290 | however. | |
5291 | ||
5292 | * We now ship all man pages in HTML format again in the | |
5293 | tarball. | |

5300 | CHANGES WITH 43: | |
5301 | ||
5302 | * This is mostly a bugfix release | |
5303 | ||
5304 | * systems lacking /etc/os-release are no longer supported. | |
5305 | ||
5306 | * Various functionality updates to libsystemd-login.so | |
5307 | ||
5308 | * Track class of PAM logins to distinguish greeters from | |
5309 | normal user logins. | |
5310 | ||

5313 | ||
5314 | CHANGES WITH 42: | |
5315 | ||
5316 | * This is an important bugfix release for v41. | |
5317 | ||
5318 | * Building man pages is now optional which should be useful | |
5319 | for those building systemd from git but unwilling to install | |
5320 | xsltproc. | |
5321 | ||
5322 | * Watchdog support for supervising services is now usable. In | |
5323 | a future release support for hardware watchdogs | |
5324 | (i.e. /dev/watchdog) will be added building on this. | |
5325 | ||
5326 | * Service start rate limiting is now configurable and can be | |
5327 | turned off per service. When a start rate limit is hit a | |
5328 | reboot can automatically be triggered. | |
5329 | ||
5330 | * New CanReboot(), CanPowerOff() bus calls in systemd-logind. | |

5335 | ||
5336 | CHANGES WITH 41: | |
5337 | ||
5338 | * The systemd binary is installed /usr/lib/systemd/systemd now; | |
5339 | An existing /sbin/init symlink needs to be adapted with the | |
5340 | package update. | |
5341 | ||
5342 | * The code that loads kernel modules has been ported to invoke | |
5343 | libkmod directly, instead of modprobe. This means we do not | |
5344 | support systems with module-init-tools anymore. | |
5345 | ||
5346 | * Watchdog support is now already useful, but still not | |
5347 | complete. | |
5348 | ||
5349 | * A new kernel command line option systemd.setenv= is | |
5350 | understood to set system wide environment variables | |
5351 | dynamically at boot. | |
5352 | ||
5353 | * We now limit the set of capabilities of systemd-journald. | |
5354 | ||
5355 | * We now set SIGPIPE to ignore by default, since it only is | |
5356 | useful in shell pipelines, and has little use in general | |
5357 | code. This can be disabled with IgnoreSIPIPE=no in unit | |
5358 | files. | |

5364 | CHANGES WITH 40: | |
5365 | ||
5366 | * This is mostly a bugfix release | |
5367 | ||
5368 | * We now expose the reason why a service failed in the | |
5369 | "Result" D-Bus property. | |
5370 | ||
5371 | * Rudimentary service watchdog support (will be completed over | |
5372 | the next few releases.) | |
5373 | ||
5374 | * When systemd forks off in order execute some service we will | |
5375 | now immediately changes its argv[0] to reflect which process | |
5376 | it will execute. This is useful to minimize the time window | |
5377 | with a generic argv[0], which makes bootcharts more useful | |

5383 | CHANGES WITH 39: | |
5384 | ||
5385 | * This is mostly a test release, but incorporates many | |
5386 | bugfixes. | |
5387 | ||
5388 | * New systemd-cgtop tool to show control groups by their | |
5389 | resource usage. | |
5390 | ||
5391 | * Linking against libacl for ACLs is optional again. If | |
5392 | disabled, support tracking device access for active logins | |
5393 | goes becomes unavailable, and so does access to the user | |
5394 | journals by the respective users. | |
5395 | ||
5396 | * If a group "adm" exists, journal files are automatically | |
5397 | owned by them, thus allow members of this group full access | |
5398 | to the system journal as well as all user journals. | |
5399 | ||
5400 | * The journal now stores the SELinux context of the logging | |
5401 | client for all entries. | |
5402 | ||
5403 | * Add C++ inclusion guards to all public headers | |
5404 | ||
5405 | * New output mode "cat" in the journal to print only text | |
5406 | messages, without any meta data like date or time. | |
5407 | ||
5408 | * Include tiny X server wrapper as a temporary stop-gap to | |
5409 | teach XOrg udev display enumeration. This is used by display | |
5410 | managers such as gdm, and will go away as soon as XOrg | |
5411 | learned native udev hotplugging for display devices. | |
5412 | ||
5413 | * Add new systemd-cat tool for executing arbitrary programs | |
5414 | with STDERR/STDOUT connected to the journal. Can also act as | |
5415 | BSD logger replacement, and does so by default. | |
5416 | ||
5417 | * Optionally store all locally generated coredumps in the | |
5418 | journal along with meta data. | |
5419 | ||
5420 | * systemd-tmpfiles learnt four new commands: n, L, c, b, for | |
5421 | writing short strings to files (for usage for /sys), and for | |
5422 | creating symlinks, character and block device nodes. | |
5423 | ||
5424 | * New unit file option ControlGroupPersistent= to make cgroups | |
5425 | persistent, following the mechanisms outlined in | |
5426 | http://www.freedesktop.org/wiki/Software/systemd/PaxControlGroups | |
5427 | ||
5428 | * Support multiple local RTCs in a sane way | |
5429 | ||
5430 | * No longer monopolize IO when replaying readahead data on | |
5431 | rotating disks, since we might starve non-file-system IO to | |
5432 | death, since fanotify() will not see accesses done by blkid, | |
5433 | or fsck. | |
5434 | ||
5435 | * Do not show kernel threads in systemd-cgls anymore, unless | |
5436 | requested with new -k switch. | |

5441 | CHANGES WITH 38: | |
5442 | ||
5443 | * This is mostly a test release, but incorporates many | |
5444 | bugfixes. | |
5445 | ||
5446 | * The git repository moved to: | |
5447 | git://anongit.freedesktop.org/systemd/systemd | |
5448 | ssh://git.freedesktop.org/git/systemd/systemd | |
5449 | ||
5450 | * First release with the journal | |
5451 | http://0pointer.de/blog/projects/the-journal.html | |
5452 | ||
5453 | * The journal replaces both systemd-kmsg-syslogd and | |
5454 | systemd-stdout-bridge. | |
5455 | ||
5456 | * New sd_pid_get_unit() API call in libsystemd-logind | |
5457 | ||
5458 | * Many systemadm clean-ups | |
5459 | ||
5460 | * Introduce remote-fs-pre.target which is ordered before all | |
5461 | remote mounts and may be used to start services before all | |
5462 | remote mounts. | |
5463 | ||
5464 | * Added Mageia support | |
5465 | ||
5466 | * Add bash completion for systemd-loginctl | |
5467 | ||
5468 | * Actively monitor PID file creation for daemons which exit in | |
5469 | the parent process before having finished writing the PID | |
5470 | file in the daemon process. Daemons which do this need to be | |
5471 | fixed (i.e. PID file creation must have finished before the | |
5472 | parent exits), but we now react a bit more gracefully to them. | |
5473 | ||
5474 | * Add colourful boot output, mimicking the well-known output | |
5475 | of existing distributions. | |
5476 | ||
5477 | * New option PassCredentials= for socket units, for | |
5478 | compatibility with a recent kernel ABI breakage. | |
5479 | ||
5480 | * /etc/rc.local is now hooked in via a generator binary, and | |
5481 | thus will no longer act as synchronization point during | |
5482 | boot. | |
5483 | ||
5484 | * systemctl list-unit-files now supports --root=. | |
5485 | ||
5486 | * systemd-tmpfiles now understands two new commands: z, Z for | |
5487 | relabelling files according to the SELinux database. This is | |
5488 | useful to apply SELinux labels to specific files in /sys, | |
5489 | among other things. | |
5490 | ||
5491 | * Output of SysV services is now forwarded to both the console | |
5492 | and the journal by default, not only just the console. | |
5493 | ||
5494 | * New man pages for all APIs from libsystemd-login. | |
5495 | ||
5496 | * The build tree got reorganized and a the build system is a | |
5497 | lot more modular allowing embedded setups to specifically | |
5498 | select the components of systemd they are interested in. | |
5499 | ||
5500 | * Support for Linux systems lacking the kernel VT subsystem is | |
5501 | restored. | |
5502 | ||
5503 | * configure's --with-rootdir= got renamed to | |
5504 | --with-rootprefix= to follow the naming used by udev and | |
5505 | kmod | |
5506 | ||
5507 | * Unless specified otherwise we will now install to /usr instead | |
5508 | of /usr/local by default. | |
5509 | ||
5510 | * Processes with '@' in argv[0][0] are now excluded from the | |
5511 | final shut-down killing spree, following the logic explained | |
5512 | in: | |
5513 | http://www.freedesktop.org/wiki/Software/systemd/RootStorageDaemons | |
5514 | ||
5515 | * All processes remaining in a service cgroup when we enter | |
5516 | the START or START_PRE states are now killed with | |
5517 | SIGKILL. That means it is no longer possible to spawn | |
5518 | background processes from ExecStart= lines (which was never | |
5519 | supported anyway, and bad style). | |
5520 | ||
5521 | * New PropagateReloadTo=/PropagateReloadFrom= options to bind | |
5522 | reloading of units together. | |
