3 | CHANGES WITH 206: |
4 | ||
5 | * The documentation has been updated to cover the various new | |
6 | concepts introduced with 205. | |
7 | ||
8 | * Unit files now understand the new %v specifier which | |
9 | resolves to the kernel version string as returned by "uname | |
10 | -r". | |
11 | ||
12 | * systemctl now supports filtering the unit list output by | |
13 | load state, active state and sub state, using the new | |
14 | --type= parameter. | |
15 | ||
16 | * "systemctl status" will now show the results of the | |
17 | condition checks (like ConditionPathExists= and similar) of | |
18 | the last start attempts of the unit. They are also logged to | |
19 | the journal. | |
20 | ||
21 | * "journalctl -b" may now be used to look for boot output of a | |
22 | specific boot. Try "journalctl -b -1" for the previous boot, | |
23 | but the syntax is substantially more powerful. | |
24 | ||
25 | * "journalctl --show-cursor" has been added which prints the | |
26 | cursor string the last shown log line. This may then be used | |
27 | with the new "journalctl --after-cursor=" switch to continue | |
28 | browsing logs from that point on. | |
29 | ||
30 | * "journalctl --force" may now be used to force regeneration | |
31 | of an FSS key. | |
32 | ||
33 | * Device ACLs may now be applied to "dead" devices nodes too, | |
28f5c779 KS |
34 | i.e. device nodes that are created based on kernel module |
35 | information of not yet loaded kernel modules. | |
408f281b LP |
36 | |
37 | * A new RPM macro has been added that may be used to apply | |
38 | tmpfiles configuration during package installation. | |
39 | ||
40 | * systemd-detect-virt and ConditionVirtualization= now can | |
41 | detect User-Mode-Linux machines (UML). | |
42 | ||
43 | * journald will now log the effective capabilities set of | |
44 | processes in the message metadata. | |
45 | ||
46 | * systemd-cryptsetup has gained support for TrueCrypt volumes. | |
47 | ||
48 | * The initrd interface has been simplified (more specifically, | |
49 | support for passing performance data via environment | |
50 | variables and fsck results via files in /run has been | |
51 | removed). These features were non-essential, and are | |
52 | nowadays available in a much nicer way by having systemd in | |
53 | the initrd serialize its state and have the hosts systemd | |
54 | deserialize it again. | |
55 | ||
28f5c779 KS |
56 | * The udev "keymap" data files and tools to apply keyboard |
57 | specific mappings of scan to key codes, and force-release | |
58 | scan code lists have been entirely replaced by a udev | |
59 | "keyboard" builtin and a hwdb data file. | |
408f281b | 60 | |
00aa832b LP |
61 | CHANGES WITH 205: |
62 | ||
63 | * Two new unit types have been introduced: | |
64 | ||
65 | Scope units are very similar to service units, however, are | |
66 | created out of pre-existing processes -- instead of PID 1 | |
67 | forking off the processes. By using scope units it is | |
68 | possible for system services and applications to group their | |
69 | own child processes (worker processes) in a powerful way | |
70 | which then maybe used to organize them, or kill them | |
71 | together, or apply resource limits on them. | |
72 | ||
73 | Slice units may be used to partition system resources in an | |
74 | hierarchial fashion and then assign other units to them. By | |
75 | default there are now three slices: system.slice (for all | |
76 | system services), user.slice (for all user sessions), | |
77 | machine.slice (for VMs and containers). | |
78 | ||
79 | Slices and scopes have been introduced primarily in | |
80 | context of the work to move cgroup handling to a | |
81 | single-writer scheme, where only PID 1 | |
82 | creates/removes/manages cgroups. | |
83 | ||
84 | * There's a new concept of "transient" units. In contrast to | |
85 | normal units these units are created via an API at runtime, | |
86 | not from configuration from disk. More specifically this | |
87 | means it is now possible to run arbitrary programs as | |
88 | independent services, with all execution parameters passed | |
89 | in via bus APIs rather than read from disk. Transient units | |
90 | make systemd substantially more dynamic then it ever was, | |
91 | and useful as a general batch manager. | |
92 | ||
93 | * logind has been updated to make use of scope and slice units | |
94 | for managing user sessions. As a user logs in he will get | |
95 | his own private slice unit, to which all sessions are added | |
96 | as scope units. We also added support for automatically | |
97 | adding an instance of user@.service for the user into the | |
98 | slice. Effectively logind will no longer create cgroup | |
99 | hierarchies on its own now, it will defer entirely to PID 1 | |
100 | for this by means of scope, service and slice units. Since | |
101 | user sessions this way become entities managed by PID 1 | |
102 | the output of "systemctl" is now a lot more comprehensive. | |
103 | ||
104 | * A new mini-daemon "systemd-machined" has been added which | |
105 | may be used by virtualization managers to register local | |
106 | VMs/containers. nspawn has been updated accordingly, and | |
107 | libvirt will be updated shortly. machined will collect a bit | |
108 | of meta information about the VMs/containers, and assign | |
109 | them their own scope unit (see above). The collected | |
110 | meta-data is then made available via the "machinectl" tool, | |
111 | and exposed in "ps" and similar tools. machined/machinectl | |
112 | is compile-time optional. | |
113 | ||
114 | * As discussed earlier, the low-level cgroup configuration | |
115 | options ControlGroup=, ControlGroupModify=, | |
116 | ControlGroupPersistent=, ControlGroupAttribute= have been | |
117 | removed. Please use high-level attribute settings instead as | |
118 | well as slice units. | |
119 | ||
120 | * A new bus call SetUnitProperties() has been added to alter | |
121 | various runtime parameters of a unit. This is primarily | |
122 | useful to alter cgroup parameters dynamically in a nice way, | |
123 | but will be extended later on to make more properties | |
124 | modifiable at runtime. systemctl gained a new set-properties | |
125 | command that wraps this call. | |
126 | ||
127 | * A new tool "systemd-run" has been added which can be used to | |
128 | run arbitrary command lines as transient services or scopes, | |
129 | while configuring a number of settings via the command | |
130 | line. This tool is currently very basic, however already | |
131 | very useful. We plan to extend this tool to even allow | |
132 | queuing of execution jobs with time triggers from the | |
133 | command line, similar in fashion to "at". | |
134 | ||
135 | * nspawn will now inform the user explicitly that kernels with | |
136 | audit enabled break containers, and suggest the user to turn | |
137 | off audit. | |
138 | ||
139 | * Support for detecting the IMA and AppArmor security | |
140 | frameworks with ConditionSecurity= has been added. | |
141 | ||
142 | * journalctl gained a new "-k" switch for showing only kernel | |
1fda0ab5 ZJS |
143 | messages, mimicking dmesg output; in addition to "--user" |
144 | and "--system" switches for showing only user's own logs | |
145 | and system logs. | |
00aa832b LP |
146 | |
147 | * systemd-delta can now show information about drop-in | |
148 | snippets extending unit files. | |
149 | ||
150 | * libsystemd-bus has been substantially updated but is still | |
151 | not available as public API. | |
152 | ||
153 | * systemd will now look for the "debug" argument on the kernel | |
154 | command line and enable debug logging, similar to | |
155 | "systemd.log_level=debug" already did before. | |
156 | ||
157 | * "systemctl set-default", "systemctl get-default" has been | |
158 | added to configure the default.target symlink, which | |
159 | controls what to boot into by default. | |
160 | ||
1fda0ab5 ZJS |
161 | * "systemctl set-log-level" has been added as a convenient |
162 | way to raise and lower systemd logging threshold. | |
163 | ||
00aa832b LP |
164 | * "systemd-analyze plot" will now show the time the various |
165 | generators needed for execution, as well as information | |
166 | about the unit file loading. | |
167 | ||
00aa832b LP |
168 | * libsystemd-journal gained a new sd_journal_open_files() call |
169 | for opening specific journal files. journactl also gained a | |
170 | new switch to expose this new functionality. Previously we | |
171 | only supported opening all files from a directory, or all | |
172 | files from the system, as opening individual files only is | |
173 | racy due to journal file rotation. | |
174 | ||
175 | * systemd gained the new DefaultEnvironment= setting in | |
176 | /etc/systemd/system.conf to set environment variables for | |
177 | all services. | |
178 | ||
179 | * If a privileged process logs a journal message with the | |
180 | OBJECT_PID= field set, then journald will automatically | |
181 | augment this with additional OBJECT_UID=, OBJECT_GID=, | |
182 | OBJECT_COMM=, OBJECT_EXE=, ... fields. This is useful if | |
183 | system services want to log events about specific client | |
184 | processes. journactl/systemctl has been updated to make use | |
185 | of this information if all log messages regarding a specific | |
186 | unit is requested. | |

606c24e3 LP |
202 | CHANGES WITH 204: |
203 | ||
204 | * The Python bindings gained some minimal support for the APIs | |
205 | exposed by libsystemd-logind. | |
206 | ||
207 | * ConditionSecurity= gained support for detecting SMACK. Since | |
208 | this condition already supports SELinux and AppArmor we only | |
209 | miss IMA for this. Patches welcome! | |

2f3fcf85 LP |
214 | CHANGES WITH 203: |
215 | ||
216 | * systemd-nspawn will now create /etc/resolv.conf if | |
217 | necessary, before bind-mounting the host's file onto it. | |
218 | ||
219 | * systemd-nspawn will now store meta information about a | |
220 | container on the container's cgroup as extended attribute | |
221 | fields, including the root directory. | |
222 | ||
223 | * The cgroup hierarchy has been reworked in many ways. All | |
224 | objects any of the components systemd creates in the cgroup | |
b82eed9a | 225 | tree are now suffixed. More specifically, user sessions are |
2f3fcf85 LP |
226 | now placed in cgroups suffixed with ".session", users in |
227 | cgroups suffixed with ".user", and nspawn containers in | |
228 | cgroups suffixed with ".nspawn". Furthermore, all cgroup | |
229 | names are now escaped in a simple scheme to avoid collision | |
230 | of userspace object names with kernel filenames. This work | |
231 | is preparation for making these objects relocatable in the | |
232 | cgroup tree, in order to allow easy resource partitioning of | |
233 | these objects without causing naming conflicts. | |
234 | ||
235 | * systemctl list-dependencies gained the new switches | |
236 | --plain, --reverse, --after and --before. | |
237 | ||
238 | * systemd-inhibit now shows the process name of processes that | |
239 | have taken an inhibitor lock. | |
240 | ||
241 | * nss-myhostname will now also resolve "localhost" | |
242 | implicitly. This makes /etc/hosts an optional file and | |
243 | nicely handles that on IPv6 ::1 maps to both "localhost" and | |
244 | the local hostname. | |
245 | ||
246 | * libsystemd-logind.so gained a new call | |
247 | sd_get_machine_names() to enumerate running containers and | |
248 | VMs (currently only supported by very new libvirt and | |
249 | nspawn). sd_login_monitor can now be used to watch | |
250 | VMs/containers coming and going. | |
251 | ||
252 | * .include is not allowed recursively anymore, and only in | |
253 | unit files. Usually it is better to use drop-in snippets in | |
254 | .d/*.conf anyway, as introduced with systemd 198. | |
255 | ||
256 | * systemd-analyze gained a new "critical-chain" command that | |
257 | determines the slowest chain of units run during system | |
258 | boot-up. It is very useful for tracking down where | |
259 | optimizing boot time is the most beneficial. | |
260 | ||
261 | * systemd will no longer allow manipulating service paths in | |
262 | the name=systemd:/system cgroup tree using ControlGroup= in | |
263 | units. (But is still fine with it in all other dirs.) | |
264 | ||
265 | * There's a new systemd-nspawn@.service service file that may | |
266 | be used to easily run nspawn containers as system | |
267 | services. With the container's root directory in | |
268 | /var/lib/container/foobar it is now sufficient to run | |
269 | "systemctl start systemd-nspawn@foobar.service" to boot it. | |
270 | ||
271 | * systemd-cgls gained a new parameter "--machine" to list only | |
272 | the processes within a certain container. | |
273 | ||
274 | * ConditionSecurity= now can check for "apparmor". We still | |
275 | are lacking checks for SMACK and IMA for this condition | |
276 | check though. Patches welcome! | |
277 | ||
278 | * A new configuration file /etc/systemd/sleep.conf has been | |
279 | added that may be used to configure which kernel operation | |
280 | systemd is supposed to execute when "suspend", "hibernate" | |
281 | or "hybrid-sleep" is requested. This makes the new kernel | |
282 | "freeze" state accessible to the user. | |
283 | ||
284 | * ENV{SYSTEMD_WANTS} in udev rules will now implicitly escape | |
285 | the passed argument if applicable. | |

ef3b5246 LP |
296 | CHANGES WITH 202: |
297 | ||
298 | * The output of 'systemctl list-jobs' got some polishing. The | |
299 | '--type=' argument may now be passed more than once. A new | |
300 | command 'systemctl list-sockets' has been added which shows | |
301 | a list of kernel sockets systemd is listening on with the | |
302 | socket units they belong to, plus the units these socket | |
303 | units activate. | |
304 | ||
305 | * The experimental libsystemd-bus library got substantial | |
306 | updates to work in conjunction with the (also experimental) | |
307 | kdbus kernel project. It works well enough to exchange | |
308 | messages with some sophistication. Note that kdbus is not | |
309 | ready yet, and the library is mostly an elaborate test case | |
310 | for now, and not installable. | |
311 | ||
312 | * systemd gained a new unit 'systemd-static-nodes.service' | |
313 | that generates static device nodes earlier during boot, and | |
314 | can run in conjunction with udev. | |
315 | ||
316 | * libsystemd-login gained a new call sd_pid_get_user_unit() | |
317 | to retrieve the user systemd unit a process is running | |
318 | in. This is useful for systems where systemd is used as | |
319 | session manager. | |
320 | ||
321 | * systemd-nspawn now places all containers in the new /machine | |
322 | top-level cgroup directory in the name=systemd | |
323 | hierarchy. libvirt will soon do the same, so that we get a | |
324 | uniform separation of /system, /user and /machine for system | |
325 | services, user processes and containers/virtual | |
326 | machines. This new cgroup hierarchy is also useful to stick | |
327 | stable names to specific container instances, which can be | |
7c04ad2d | 328 | recognized later this way (this name may be controlled |
ef3b5246 LP |
329 | via systemd-nspawn's new -M switch). libsystemd-login also |
330 | gained a new call sd_pid_get_machine_name() to retrieve the | |
331 | name of the container/VM a specific process belongs to. | |
332 | ||
333 | * bootchart can now store its data in the journal. | |
334 | ||
335 | * libsystemd-journal gained a new call | |
336 | sd_journal_add_conjunction() for AND expressions to the | |
337 | matching logic. This can be used to express more complex | |
338 | logical expressions. | |
339 | ||
340 | * journactl can now take multiple --unit= and --user-unit= | |
341 | switches. | |
342 | ||
343 | * The cryptsetup logic now understands the "luks.key=" kernel | |
344 | command line switch for specifying a file to read the | |
7c04ad2d | 345 | decryption key from. Also, if a configured key file is not |
ef3b5246 LP |
346 | found the tool will now automatically fall back to prompting |
347 | the user. | |
348 | ||
cbeabcfb ZJS |
349 | * Python systemd.journal module was updated to wrap recently |
350 | added functions from libsystemd-journal. The interface was | |
351 | changed to bring the low level interface in s.j._Reader | |
352 | closer to the C API, and the high level interface in | |
353 | s.j.Reader was updated to wrap and convert all data about | |
354 | an entry. | |

d3a86981 LP |
363 | CHANGES WITH 201: |
364 | ||
365 | * journalctl --update-catalog now understands a new --root= | |
366 | option to operate on catalogs found in a different root | |
367 | directory. | |
368 | ||
369 | * During shutdown after systemd has terminated all running | |
370 | services a final killing loop kills all remaining left-over | |
371 | processes. We will now print the name of these processes | |
372 | when we send SIGKILL to them, since this usually indicates a | |
373 | problem. | |
374 | ||
375 | * If /etc/crypttab refers to password files stored on | |
376 | configured mount points automatic dependencies will now be | |
377 | generated to ensure the specific mount is established first | |
378 | before the key file is attempted to be read. | |
379 | ||
380 | * 'systemctl status' will now show information about the | |
381 | network sockets a socket unit is listening on. | |
382 | ||
383 | * 'systemctl status' will also shown information about any | |
384 | drop-in configuration file for units. (Drop-In configuration | |
385 | files in this context are files such as | |
386 | /etc/systemd/systemd/foobar.service.d/*.conf) | |
387 | ||
388 | * systemd-cgtop now optionally shows summed up CPU times of | |
389 | cgroups. Press '%' while running cgtop to switch between | |
390 | percentage and absolute mode. This is useful to determine | |
391 | which cgroups use up the most CPU time over the entire | |
392 | runtime of the system. systemd-cgtop has also been updated | |
393 | to be 'pipeable' for processing with further shell tools. | |
394 | ||
395 | * 'hostnamectl set-hostname' will now allow setting of FQDN | |
396 | hostnames. | |
397 | ||
398 | * The formatting and parsing of time span values has been | |
399 | changed. The parser now understands fractional expressions | |
400 | such as "5.5h". The formatter will now output fractional | |
401 | expressions for all time spans under 1min, i.e. "5.123456s" | |
402 | rather than "5s 123ms 456us". For time spans under 1s | |
403 | millisecond values are shown, for those under 1ms | |
404 | microsecond values are shown. This should greatly improve | |
405 | all time-related output of systemd. | |
406 | ||
407 | * libsystemd-login and libsystemd-journal gained new | |
408 | functions for querying the poll() events mask and poll() | |
409 | timeout value for integration into arbitrary event | |
410 | loops. | |
411 | ||
412 | * localectl gained the ability to list available X11 keymaps | |
413 | (models, layouts, variants, options). | |
414 | ||
415 | * 'systemd-analyze dot' gained the ability to filter for | |
416 | specific units via shell-style globs, to create smaller, | |
417 | more useful graphs. I.e. it's now possible to create simple | |
418 | graphs of all the dependencies between only target units, or | |
419 | of all units that Avahi has dependencies with. | |

429 | CHANGES WITH 200: |
430 | ||
431 | * The boot-time readahead implementation for rotating media | |
432 | will now read the read-ahead data in multiple passes which | |
433 | consist of all read requests made in equidistant time | |
434 | intervals. This means instead of strictly reading read-ahead | |
435 | data in its physical order on disk we now try to find a | |
436 | middle ground between physical and access time order. | |
437 | ||
438 | * /etc/os-release files gained a new BUILD_ID= field for usage | |
439 | on operating systems that provide continuous builds of OS | |
440 | images. | |

446 | CHANGES WITH 199: |
447 | ||
448 | * systemd-python gained an API exposing libsystemd-daemon. | |
449 | ||
450 | * The SMACK setup logic gained support for uploading CIPSO | |
451 | security policy. | |
452 | ||
453 | * Behaviour of PrivateTmp=, ReadWriteDirectories=, | |
454 | ReadOnlyDirectories= and InaccessibleDirectories= has | |
455 | changed. The private /tmp and /var/tmp directories are now | |
456 | shared by all processes of a service (which means | |
457 | ExecStartPre= may now leave data in /tmp that ExecStart= of | |
458 | the same service can still access). When a service is | |
459 | stopped its temporary directories are immediately deleted | |
a87197f5 | 460 | (normal clean-up with tmpfiles is still done in addition to |
35911459 LP |
461 | this though). |
462 | ||
463 | * By default, systemd will now set a couple of sysctl | |
464 | variables in the kernel: the safe sysrq options are turned | |
465 | on, IP route verification is turned on, and source routing | |
466 | disabled. The recently added hardlink and softlink | |
467 | protection of the kernel is turned on. These settings should | |
468 | be reasonably safe, and good defaults for all new systems. | |
469 | ||
470 | * The predictable network naming logic may now be turned off | |
a87197f5 | 471 | with a new kernel command line switch: net.ifnames=0. |
35911459 LP |
472 | |
473 | * A new libsystemd-bus module has been added that implements a | |
474 | pretty complete D-Bus client library. For details see: | |
475 | ||
476 | http://lists.freedesktop.org/archives/systemd-devel/2013-March/009797.html | |
477 | ||
c20d8298 | 478 | * journald will now explicitly flush the journal files to disk |
a87197f5 ZJS |
479 | at the latest 5min after each write. The file will then also |
480 | be marked offline until the next write. This should increase | |
481 | reliability in case of a crash. The synchronization delay | |
482 | can be configured via SyncIntervalSec= in journald.conf. | |
35911459 LP |
483 | |
484 | * There's a new remote-fs-setup.target unit that can be used | |
485 | to pull in specific services when at least one remote file | |
486 | system is to be mounted. | |
487 | ||
488 | * There are new targets timers.target and paths.target as | |
489 | canonical targets to pull user timer and path units in | |
490 | from. This complements sockets.target with a similar | |
491 | purpose for socket units. | |
492 | ||
6a7d3d68 LP |
493 | * libudev gained a new call udev_device_set_attribute_value() |
494 | to set sysfs attributes of a device. | |
495 | ||
a87197f5 ZJS |
496 | * The udev daemon now sets the default number of worker |
497 | processes executed in parallel based on the number of available | |
c20d8298 | 498 | CPUs instead of the amount of available RAM. This is supposed |
ab06eef8 | 499 | to provide a more reliable default and limit a too aggressive |
c20d8298 KS |
500 | paralellism for setups with 1000s of devices connected. |

85d68397 LP |
512 | CHANGES WITH 198: |
513 | ||
514 | * Configuration of unit files may now be extended via drop-in | |
515 | files without having to edit/override the unit files | |
516 | themselves. More specifically, if the administrator wants to | |
517 | change one value for a service file foobar.service he can | |
518 | now do so by dropping in a configuration snippet into | |
ad88e758 | 519 | /etc/systemd/system/foobar.service.d/*.conf. The unit logic |
85d68397 LP |
520 | will load all these snippets and apply them on top of the |
521 | main unit configuration file, possibly extending or | |
522 | overriding its settings. Using these drop-in snippets is | |
40e21da8 KS |
523 | generally nicer than the two earlier options for changing |
524 | unit files locally: copying the files from | |
85d68397 LP |
525 | /usr/lib/systemd/system/ to /etc/systemd/system/ and editing |
526 | them there; or creating a new file in /etc/systemd/system/ | |
527 | that incorporates the original one via ".include". Drop-in | |
528 | snippets into these .d/ directories can be placed in any | |
fd868975 | 529 | directory systemd looks for units in, and the usual |
85d68397 LP |
530 | overriding semantics between /usr/lib, /etc and /run apply |
531 | for them too. | |
532 | ||
533 | * Most unit file settings which take lists of items can now be | |
6aa8d43a | 534 | reset by assigning the empty string to them. For example, |
85d68397 LP |
535 | normally, settings such as Environment=FOO=BAR append a new |
536 | environment variable assignment to the environment block, | |
537 | each time they are used. By assigning Environment= the empty | |
538 | string the environment block can be reset to empty. This is | |
539 | particularly useful with the .d/*.conf drop-in snippets | |
156f7d09 KS |
540 | mentioned above, since this adds the ability to reset list |
541 | settings from vendor unit files via these drop-ins. | |
85d68397 LP |
542 | |
543 | * systemctl gained a new "list-dependencies" command for | |
544 | listing the dependencies of a unit recursively. | |
545 | ||
40e21da8 | 546 | * Inhibitors are now honored and listed by "systemctl |
85d68397 LP |
547 | suspend", "systemctl poweroff" (and similar) too, not only |
548 | GNOME. These commands will also list active sessions by | |
549 | other users. | |
550 | ||
551 | * Resource limits (as exposed by the various control group | |
552 | controllers) can now be controlled dynamically at runtime | |
553 | for all units. More specifically, you can now use a command | |
554 | like "systemctl set-cgroup-attr foobar.service cpu.shares | |
555 | 2000" to alter the CPU shares a specific service gets. These | |
6aa8d43a | 556 | settings are stored persistently on disk, and thus allow the |
85d68397 LP |
557 | administrator to easily adjust the resource usage of |
558 | services with a few simple commands. This dynamic resource | |
6aa8d43a | 559 | management logic is also available to other programs via the |
85d68397 LP |
560 | bus. Almost any kernel cgroup attribute and controller is |
561 | supported. | |
562 | ||
563 | * systemd-vconsole-setup will now copy all font settings to | |
6aa8d43a LP |
564 | all allocated VTs, where it previously applied them only to |
565 | the foreground VT. | |
85d68397 LP |
566 | |
567 | * libsystemd-login gained the new sd_session_get_tty() API | |
568 | call. | |
569 | ||
6aa8d43a LP |
570 | * This release drops support for a few legacy or |
571 | distribution-specific LSB facility names when parsing init | |
572 | scripts: $x-display-manager, $mail-transfer-agent, | |
85d68397 LP |
573 | $mail-transport-agent, $mail-transfer-agent, $smtp, |
574 | $null. Also, the mail-transfer-agent.target unit backing | |
575 | this has been removed. Distributions which want to retain | |
6aa8d43a LP |
576 | compatibility with this should carry the burden for |
577 | supporting this themselves and patch support for these back | |
578 | in, if they really need to. Also, the facilities $syslog and | |
579 | $local_fs are now ignored, since systemd does not support | |
580 | early-boot LSB init scripts anymore, and these facilities | |
581 | are implied anyway for normal services. syslog.target has | |
582 | also been removed. | |
85d68397 | 583 | |
40e21da8 | 584 | * There are new bus calls on PID1's Manager object for |
6aa8d43a | 585 | cancelling jobs, and removing snapshot units. Previously, |
85d68397 LP |
586 | both calls were only available on the Job and Snapshot |
587 | objects themselves. | |
588 | ||
589 | * systemd-journal-gatewayd gained SSL support. | |
590 | ||
591 | * The various "environment" files, such as /etc/locale.conf | |
592 | now support continuation lines with a backslash ("\") as | |
593 | last character in the line, similar in style (but different) | |
594 | to how this is supported in shells. | |
595 | ||
596 | * For normal user processes the _SYSTEMD_USER_UNIT= field is | |
597 | now implicitly appended to every log entry logged. systemctl | |
598 | has been updated to filter by this field when operating on a | |
599 | user systemd instance. | |
600 | ||
601 | * nspawn will now implicitly add the CAP_AUDIT_WRITE and | |
602 | CAP_AUDIT_CONTROL capabilities to the capabilities set for | |
603 | the container. This makes it easier to boot unmodified | |
604 | Fedora systems in a container, which however still requires | |
605 | audit=0 to be passed on the kernel command line. Auditing in | |
606 | kernel and userspace is unfortunately still too broken in | |
607 | context of containers, hence we recommend compiling it out | |
608 | of the kernel or using audit=0. Hopefully this will be fixed | |
609 | one day for good in the kernel. | |
610 | ||
611 | * nspawn gained the new --bind= and --bind-ro= parameters to | |
612 | bind mount specific directories from the host into the | |
613 | container. | |
614 | ||
40e21da8 | 615 | * nspawn will now mount its own devpts file system instance |
6aa8d43a | 616 | into the container, in order not to leak pty devices from |
85d68397 LP |
617 | the host into the container. |
618 | ||
619 | * systemd will now read the firmware boot time performance | |
6aa8d43a LP |
620 | information from the EFI variables, if the used boot loader |
621 | supports this, and takes it into account for boot performance | |
622 | analysis via "systemd-analyze". This is currently supported | |
623 | only in conjunction with Gummiboot, but could be supported | |
624 | by other boot loaders too. For details see: | |
85d68397 LP |
625 | |
626 | http://www.freedesktop.org/wiki/Software/systemd/BootLoaderInterface | |
627 | ||
628 | * A new generator has been added that automatically mounts the | |
629 | EFI System Partition (ESP) to /boot, if that directory | |
6aa8d43a LP |
630 | exists, is empty, and no other file system has been |
631 | configured to be mounted there. | |
85d68397 LP |
632 | |
633 | * logind will now send out PrepareForSleep(false) out | |
634 | unconditionally, after coming back from suspend. This may be | |
635 | used by applications as asynchronous notification for | |
636 | system resume events. | |
637 | ||
638 | * "systemctl unlock-sessions" has been added, that allows | |
639 | unlocking the screens of all user sessions at once, similar | |
640 | how "systemctl lock-sessions" already locked all users | |
40e21da8 | 641 | sessions. This is backed by a new D-Bus call UnlockSessions(). |
85d68397 LP |
642 | |
643 | * "loginctl seat-status" will now show the master device of a | |
644 | seat. (i.e. the device of a seat that needs to be around for | |
645 | the seat to be considered available, usually the graphics | |
646 | card). | |
647 | ||
648 | * tmpfiles gained a new "X" line type, that allows | |
649 | configuration of files and directories (with wildcards) that | |
650 | shall be excluded from automatic cleanup ("aging"). | |
651 | ||
bf933560 KS |
652 | * udev default rules set the device node permissions now only |
653 | at "add" events, and do not change them any longer with a | |
654 | later "change" event. | |
85d68397 LP |
655 | |
656 | * The log messages for lid events and power/sleep keypresses | |
657 | now carry a message ID. | |
658 | ||
659 | * We now have a substantially larger unit test suite, but this | |
660 | continues to be work in progress. | |
661 | ||
662 | * udevadm hwdb gained a new --root= parameter to change the | |
663 | root directory to operate relative to. | |
664 | ||
40e21da8 KS |
665 | * logind will now issue a background sync() request to the kernel |
666 | early at shutdown, so that dirty buffers are flushed to disk early | |
85d68397 LP |
667 | instead of at the last moment, in order to optimize shutdown |
668 | times a little. | |
669 | ||
670 | * A new bootctl tool has been added that is an interface for | |
671 | certain boot loader operations. This is currently a preview | |
672 | and is likely to be extended into a small mechanism daemon | |
673 | like timedated, localed, hostnamed, and can be used by | |
674 | graphical UIs to enumerate available boot options, and | |
675 | request boot into firmware operations. | |
676 | ||
677 | * systemd-bootchart has been relicensed to LGPLv2.1+ to match | |
678 | the rest of the package. It also has been updated to work | |
679 | correctly in initrds. | |
680 | ||
681 | * Policykit previously has been runtime optional, and is now | |
682 | also compile time optional via a configure switch. | |
683 | ||
684 | * systemd-analyze has been reimplemented in C. Also "systemctl | |
685 | dot" has moved into systemd-analyze. | |
686 | ||
687 | * "systemctl status" with no further parameters will now print | |
688 | the status of all active or failed units. | |
689 | ||
690 | * Operations such as "systemctl start" can now be executed | |
691 | with a new mode "--irreversible" which may be used to queue | |
692 | operations that cannot accidentally be reversed by a later | |
6aa8d43a | 693 | job queuing. This is by default used to make shutdown |
85d68397 LP |
694 | requests more robust. |
695 | ||
696 | * The Python API of systemd now gained a new module for | |
697 | reading journal files. | |
698 | ||
699 | * A new tool kernel-install has been added that can install | |
700 | kernel images according to the Boot Loader Specification: | |
701 | ||
702 | http://www.freedesktop.org/wiki/Specifications/BootLoaderSpec | |
703 | ||
704 | * Boot time console output has been improved to provide | |
6aa8d43a | 705 | animated boot time output for hanging jobs. |
85d68397 LP |
706 | |
707 | * A new tool systemd-activate has been added which can be used | |
708 | to test socket activation with, directly from the command | |
709 | line. This should make it much easier to test and debug | |
710 | socket activation in daemons. | |
711 | ||
712 | * journalctl gained a new "--reverse" (or -r) option to show | |
713 | journal output in reverse order (i.e. newest line first). | |
714 | ||
43447fb7 LP |
715 | * journalctl gained a new "--pager-end" (or -e) option to jump |
716 | to immediately jump to the end of the journal in the | |
717 | pager. This is only supported in conjunction with "less". | |
718 | ||
85d68397 LP |
719 | * journalctl gained a new "--user-unit=" option, that works |
720 | similar to "--unit=" but filters for user units rather than | |
721 | system units. | |
722 | ||
723 | * A number of unit files to ease adoption of systemd in | |
724 | initrds has been added. This moves some minimal logic from | |
725 | the various initrd implementations into systemd proper. | |
726 | ||
727 | * The journal files are now owned by a new group | |
728 | "systemd-journal", which exists specifically to allow access | |
729 | to the journal, and nothing else. Previously, we used the | |
6aa8d43a | 730 | "adm" group for that, which however possibly covers more |
85d68397 LP |
731 | than just journal/log file access. This new group is now |
732 | already used by systemd-journal-gatewayd to ensure this | |
733 | daemon gets access to the journal files and as little else | |
734 | as possible. Note that "make install" will also set FS ACLs | |
735 | up for /var/log/journal to give "adm" and "wheel" read | |
736 | access to it, in addition to "systemd-journal" which owns | |
737 | the journal files. We recommend that packaging scripts also | |
6aa8d43a | 738 | add read access to "adm" + "wheel" to /var/log/journal, and |
85d68397 LP |
739 | all existing/future journal files. To normal users and |
740 | administrators little changes, however packagers need to | |
741 | ensure to create the "systemd-journal" system group at | |
742 | package installation time. | |
743 | ||
744 | * The systemd-journal-gatewayd now runs as unprivileged user | |
745 | systemd-journal-gateway:systemd-journal-gateway. Packaging | |
746 | scripts need to create these system user/group at | |
747 | installation time. | |
748 | ||
749 | * timedated now exposes a new boolean property CanNTP that | |
750 | indicates whether a local NTP service is available or not. | |
751 | ||
752 | * systemd-detect-virt will now also detect xen PVs | |
753 | ||
40e21da8 KS |
754 | * The pstore file system is now mounted by default, if it is |
755 | available. | |
85d68397 | 756 | |
1aed4590 LP |
757 | * In addition to the SELinux and IMA policies we will now also |
758 | load SMACK policies at early boot. | |

775 | CHANGES WITH 197: |
776 | ||
777 | * Timer units now support calendar time events in addition to | |
778 | monotonic time events. That means you can now trigger a unit | |
779 | based on a calendar time specification such as "Thu,Fri | |
780 | 2013-*-1,5 11:12:13" which refers to 11:12:13 of the first | |
781 | or fifth day of any month of the year 2013, given that it is | |
782 | a thursday or friday. This brings timer event support | |
783 | considerably closer to cron's capabilities. For details on | |
784 | the supported calendar time specification language see | |
785 | systemd.time(7). | |
786 | ||
787 | * udev now supports a number of different naming policies for | |
788 | network interfaces for predictable names, and a combination | |
789 | of these policies is now the default. Please see this wiki | |
790 | document for details: | |
791 | ||
792 | http://www.freedesktop.org/wiki/Software/systemd/PredictableNetworkInterfaceNames | |
793 | ||
794 | * Auke Kok's bootchart implementation has been added to the | |
795 | systemd tree. It's an optional component that can graph the | |
796 | boot in quite some detail. It's one of the best bootchart | |
797 | implementations around and minimal in its code and | |
798 | dependencies. | |
799 | ||
800 | * nss-myhostname has been integrated into the systemd source | |
801 | tree. nss-myhostname guarantees that the local hostname | |
802 | always stays resolvable via NSS. It has been a weak | |
803 | requirement of systemd-hostnamed since a long time, and | |
804 | since its code is actually trivial we decided to just | |
805 | include it in systemd's source tree. It can be turned off | |
806 | with a configure switch. | |
807 | ||
808 | * The read-ahead logic is now capable of properly detecting | |
809 | whether a btrfs file system is on SSD or rotating media, in | |
810 | order to optimize the read-ahead scheme. Previously, it was | |
811 | only capable of detecting this on traditional file systems | |
812 | such as ext4. | |
813 | ||
814 | * In udev, additional device properties are now read from the | |
815 | IAB in addition to the OUI database. Also, Bluetooth company | |
816 | identities are attached to the devices as well. | |
817 | ||
818 | * In service files %U may be used as specifier that is | |
819 | replaced by the configured user name of the service. | |
820 | ||
821 | * nspawn may now be invoked without a controlling TTY. This | |
822 | makes it suitable for invocation as its own service. This | |
823 | may be used to set up a simple containerized server system | |
824 | using only core OS tools. | |
825 | ||
826 | * systemd and nspawn can now accept socket file descriptors | |
827 | when they are started for socket activation. This enables | |
828 | implementation of socket activated nspawn | |
829 | containers. i.e. think about autospawning an entire OS image | |
830 | when the first SSH or HTTP connection is received. We expect | |
831 | that similar functionality will also be added to libvirt-lxc | |
832 | eventually. | |
833 | ||
834 | * journalctl will now suppress ANSI color codes when | |
835 | presenting log data. | |
836 | ||
837 | * systemctl will no longer show control group information for | |
838 | a unit if a the control group is empty anyway. | |
839 | ||
840 | * logind can now automatically suspend/hibernate/shutdown the | |
841 | system on idle. | |
842 | ||
843 | * /etc/machine-info and hostnamed now also expose the chassis | |
844 | type of the system. This can be used to determine whether | |
845 | the local system is a laptop, desktop, handset or | |
846 | tablet. This information may either be configured by the | |
847 | user/vendor or is automatically determined from ACPI and DMI | |
848 | information if possible. | |
849 | ||
850 | * A number of PolicyKit actions are now bound together with | |
851 | "imply" rules. This should simplify creating UIs because | |
852 | many actions will now authenticate similar ones as well. | |
853 | ||
854 | * Unit files learnt a new condition ConditionACPower= which | |
855 | may be used to conditionalize a unit depending on whether an | |
856 | AC power source is connected or not, of whether the system | |
857 | is running on battery power. | |
858 | ||
859 | * systemctl gained a new "is-failed" verb that may be used in | |
860 | shell scripts and suchlike to check whether a specific unit | |
861 | is in the "failed" state. | |
862 | ||
863 | * The EnvironmentFile= setting in unit files now supports file | |
864 | globbing, and can hence be used to easily read a number of | |
865 | environment files at once. | |
866 | ||
867 | * systemd will no longer detect and recognize specific | |
868 | distributions. All distribution-specific #ifdeffery has been | |
869 | removed, systemd is now fully generic and | |
870 | distribution-agnostic. Effectively, not too much is lost as | |
871 | a lot of the code is still accessible via explicit configure | |
872 | switches. However, support for some distribution specific | |
873 | legacy configuration file formats has been dropped. We | |
874 | recommend distributions to simply adopt the configuration | |
875 | files everybody else uses now and convert the old | |
876 | configuration from packaging scripts. Most distributions | |
877 | already did that. If that's not possible or desirable, | |
878 | distributions are welcome to forward port the specific | |
879 | pieces of code locally from the git history. | |
880 | ||
881 | * When logging a message about a unit systemd will now always | |
882 | log the unit name in the message meta data. | |
883 | ||
884 | * localectl will now also discover system locale data that is | |
885 | not stored in locale archives, but directly unpacked. | |
886 | ||
887 | * logind will no longer unconditionally use framebuffer | |
888 | devices as seat masters, i.e. as devices that are required | |
889 | to be existing before a seat is considered preset. Instead, | |
890 | it will now look for all devices that are tagged as | |
891 | "seat-master" in udev. By default framebuffer devices will | |
892 | be marked as such, but depending on local systems other | |
893 | devices might be marked as well. This may be used to | |
894 | integrate graphics cards using closed source drivers (such | |
895 | as NVidia ones) more nicely into logind. Note however, that | |
896 | we recommend using the open source NVidia drivers instead, | |
897 | and no udev rules for the closed-source drivers will be | |
898 | shipped from us upstream. | |

0428ddb7 LP |
914 | CHANGES WITH 196: |
915 | ||
916 | * udev gained support for loading additional device properties | |
917 | from an indexed database that is keyed by vendor/product IDs | |
918 | and similar device identifiers. For the beginning this | |
919 | "hwdb" is populated with data from the well-known PCI and | |
920 | USB database, but also includes PNP, ACPI and OID data. In | |
921 | the longer run this indexed database shall grow into | |
922 | becoming the one central database for non-essential | |
923 | userspace device metadata. Previously, data from the PCI/USB | |
96ec33c0 | 924 | database was only attached to select devices, since the |
0428ddb7 | 925 | lookup was a relatively expensive operation due to O(n) time |
96ec33c0 LP |
926 | complexity (with n being the number of entries in the |
927 | database). Since this is now O(1), we decided to add in this | |
928 | data for all devices where this is available, by | |
0428ddb7 LP |
929 | default. Note that the indexed database needs to be rebuilt |
930 | when new data files are installed. To achieve this you need | |
931 | to update your packaging scripts to invoke "udevadm hwdb | |
932 | --update" after installation of hwdb data files. For | |
933 | RPM-based distributions we introduced the new | |
934 | %udev_hwdb_update macro for this purpose. | |
935 | ||
936 | * The Journal gained support for the "Message Catalog", an | |
937 | indexed database to link up additional information with | |
938 | journal entries. For further details please check: | |
939 | ||
940 | http://www.freedesktop.org/wiki/Software/systemd/catalog | |
941 | ||
942 | The indexed message catalog database also needs to be | |
943 | rebuilt after installation of message catalog files. Use | |
944 | "journalctl --update-catalog" for this. For RPM-based | |
945 | distributions we introduced the %journal_catalog_update | |
946 | macro for this purpose. | |
947 | ||
948 | * The Python Journal bindings gained support for the standard | |
949 | Python logging framework. | |
950 | ||
951 | * The Journal API gained new functions for checking whether | |
952 | the underlying file system of a journal file is capable of | |
953 | properly reporting file change notifications, or whether | |
954 | applications that want to reflect journal changes "live" | |
ab06eef8 | 955 | need to recheck journal files continuously in appropriate |
0428ddb7 LP |
956 | time intervals. |
957 | ||
958 | * It is now possible to set the "age" field for tmpfiles | |
959 | entries to 0, indicating that files matching this entry | |
960 | shall always be removed when the directories are cleaned up. | |
961 | ||
962 | * coredumpctl gained a new "gdb" verb which invokes gdb | |
963 | right-away on the selected coredump. | |
964 | ||
965 | * There's now support for "hybrid sleep" on kernels that | |
966 | support this, in addition to "suspend" and "hibernate". Use | |
967 | "systemctl hybrid-sleep" to make use of this. | |
968 | ||
969 | * logind's HandleSuspendKey= setting (and related settings) | |
970 | now gained support for a new "lock" setting to simply | |
971 | request the screen lock on all local sessions, instead of | |
972 | actually executing a suspend or hibernation. | |
973 | ||
974 | * systemd will now mount the EFI variables file system by | |
975 | default. | |
976 | ||
977 | * Socket units now gained support for configuration of the | |
978 | SMACK security label. | |
979 | ||
980 | * timedatectl will now output the time of the last and next | |
981 | daylight saving change. | |
982 | ||
983 | * We dropped support for various legacy and distro-specific | |
984 | concepts, such as insserv, early-boot SysV services | |
985 | (i.e. those for non-standard runlevels such as 'b' or 'S') | |
986 | or ArchLinux /etc/rc.conf support. We recommend the | |
987 | distributions who still need support this to either continue | |
988 | to maintain the necessary patches downstream, or find a | |
989 | different solution. (Talk to us if you have questions!) | |
990 | ||
991 | * Various systemd components will now bypass PolicyKit checks | |
992 | for root and otherwise handle properly if PolicyKit is not | |
993 | found to be around. This should fix most issues for | |
994 | PolicyKit-less systems. Quite frankly this should have been | |
995 | this way since day one. It is absolutely our intention to | |
996 | make systemd work fine on PolicyKit-less systems, and we | |
997 | consider it a bug if something doesn't work as it should if | |
998 | PolicyKit is not around. | |
999 | ||
1000 | * For embedded systems it is now possible to build udev and | |
1001 | systemd without blkid and/or kmod support. | |
1002 | ||
1003 | * "systemctl switch-root" is now capable of switching root | |
1004 | more than once. I.e. in addition to transitions from the | |
1005 | initrd to the host OS it is now possible to transition to | |
1006 | further OS images from the host. This is useful to implement | |
1007 | offline updating tools. | |
1008 | ||
1009 | * Various other additions have been made to the RPM macros | |
1010 | shipped with systemd. Use %udev_rules_update() after | |
1011 | installing new udev rules files. %_udevhwdbdir, | |
1012 | %_udevrulesdir, %_journalcatalogdir, %_tmpfilesdir, | |
1013 | %_sysctldir are now available which resolve to the right | |
1014 | directories for packages to place various data files in. | |
1015 | ||
1016 | * journalctl gained the new --full switch (in addition to | |
1017 | --all, to disable ellipsation for long messages. | |

139ee8cc LP |
1029 | CHANGES WITH 195: |
1030 | ||
6827101a | 1031 | * journalctl gained new --since= and --until= switches to |
139ee8cc LP |
1032 | filter by time. It also now supports nice filtering for |
1033 | units via --unit=/-u. | |
1034 | ||
6827101a | 1035 | * Type=oneshot services may use ExecReload= and do the |
139ee8cc LP |
1036 | right thing. |
1037 | ||
1038 | * The journal daemon now supports time-based rotation and | |
1039 | vacuuming, in addition to the usual disk-space based | |
1040 | rotation. | |
1041 | ||
1042 | * The journal will now index the available field values for | |
1043 | each field name. This enables clients to show pretty drop | |
1044 | downs of available match values when filtering. The bash | |
1045 | completion of journalctl has been updated | |
1046 | accordingly. journalctl gained a new switch -F to list all | |
1047 | values a certain field takes in the journal database. | |
1048 | ||
1049 | * More service events are now written as structured messages | |
1050 | to the journal, and made recognizable via message IDs. | |
1051 | ||
1052 | * The timedated, localed and hostnamed mini-services which | |
1053 | previously only provided support for changing time, locale | |
1054 | and hostname settings from graphical DEs such as GNOME now | |
1055 | also have a minimal (but very useful) text-based client | |
1056 | utility each. This is probably the nicest way to changing | |
1057 | these settings from the command line now, especially since | |
1058 | it lists available options and is fully integrated with bash | |
1059 | completion. | |
1060 | ||
1061 | * There's now a new tool "systemd-coredumpctl" to list and | |
1062 | extract coredumps from the journal. | |
1063 | ||
1064 | * We now install a README each in /var/log/ and | |
1065 | /etc/rc.d/init.d explaining where the system logs and init | |
1066 | scripts went. This hopefully should help folks who go to | |
1067 | that dirs and look into the otherwise now empty void and | |
1068 | scratch their heads. | |
1069 | ||
1070 | * When user-services are invoked (by systemd --user) the | |
1071 | $MANAGERPID env var is set to the PID of systemd. | |
1072 | ||
1073 | * SIGRTMIN+24 when sent to a --user instance will now result | |
1074 | in immediate termination of systemd. | |
1075 | ||
1076 | * gatewayd received numerous feature additions such as a | |
1077 | "follow" mode, for live syncing and filtering. | |
1078 | ||
1079 | * browse.html now allows filtering and showing detailed | |
1080 | information on specific entries. Keyboard navigation and | |
1081 | mouse screen support has been added. | |
1082 | ||
1083 | * gatewayd/journalctl now supports HTML5/JSON | |
1084 | Server-Sent-Events as output. | |
1085 | ||
1cb88f2c | 1086 | * The SysV init script compatibility logic will now |
139ee8cc LP |
1087 | heuristically determine whether a script supports the |
1088 | "reload" verb, and only then make this available as | |
1089 | "systemctl reload". | |
1090 | ||
15f47220 | 1091 | * "systemctl status --follow" has been removed, use "journalctl |
139ee8cc LP |
1092 | -u" instead. |
1093 | ||
1094 | * journald.conf's RuntimeMinSize=, PersistentMinSize= settings | |
1095 | have been removed since they are hardly useful to be | |
1096 | configured. | |
1097 | ||
1098 | * And I'd like to take the opportunity to specifically mention | |
1099 | Zbigniew for his great contributions. Zbigniew, you rock! | |

1109 | CHANGES WITH 194: |
1110 | ||
1111 | * If /etc/vconsole.conf is non-existent or empty we will no | |
1112 | longer load any console font or key map at boot by | |
1113 | default. Instead the kernel defaults will be left | |
1114 | intact. This is definitely the right thing to do, as no | |
1115 | configuration should mean no configuration, and hard-coding | |
1116 | font names that are different on all archs is probably a bad | |
1117 | idea. Also, the kernel default key map and font should be | |
1118 | good enough for most cases anyway, and mostly identical to | |
1119 | the userspace fonts/key maps we previously overloaded them | |
1120 | with. If distributions want to continue to default to a | |
1121 | non-kernel font or key map they should ship a default | |
1122 | /etc/vconsole.conf with the appropriate contents. | |

597c52cf LP |
1128 | CHANGES WITH 193: |
1129 | ||
1130 | * journalctl gained a new --cursor= switch to show entries | |
1131 | starting from the specified location in the journal. | |
1132 | ||
1133 | * We now enforce a size limit on journal entry fields exported | |
1134 | with "-o json" in journalctl. Fields larger than 4K will be | |
1135 | assigned null. This can be turned off with --all. | |
1136 | ||
1137 | * An (optional) journal gateway daemon is now available as | |
1138 | "systemd-journal-gatewayd.service". This service provides | |
1139 | access to the journal via HTTP and JSON. This functionality | |
1140 | will be used to implement live log synchronization in both | |
1141 | pull and push modes, but has various other users too, such | |
1142 | as easy log access for debugging of embedded devices. Right | |
1143 | now it is already useful to retrieve the journal via HTTP: | |
1144 | ||
1145 | # systemctl start systemd-journal-gatewayd.service | |
1146 | # wget http://localhost:19531/entries | |
1147 | ||
1148 | This will download the journal contents in a | |
1149 | /var/log/messages compatible format. The same as JSON: | |
1150 | ||
1151 | # curl -H"Accept: application/json" http://localhost:19531/entries | |
1152 | ||
1153 | This service is also accessible via a web browser where a | |
1154 | single static HTML5 app is served that uses the JSON logic | |
1155 | to enable the user to do some basic browsing of the | |
1156 | journal. This will be extended later on. Here's an example | |
1157 | screenshot of this app in its current state: | |

1164 | CHANGES WITH 192: |
1165 | ||
1166 | * The bash completion logic is now available for journalctl | |
1167 | too. | |
1168 | ||
1169 | * We don't mount the "cpuset" controller anymore together with | |
1170 | "cpu" and "cpuacct", as "cpuset" groups generally cannot be | |
1171 | started if no parameters are assigned to it. "cpuset" hence | |
1172 | broke code that assumed it it could create "cpu" groups and | |
1173 | just start them. | |
1174 | ||
1175 | * journalctl -f will now subscribe to terminal size changes, | |
1176 | and line break accordingly. | |

b6a86739 LP |
1181 | CHANGES WITH 191: |
1182 | ||
1183 | * nspawn will now create a symlink /etc/localtime in the | |
1184 | container environment, copying the host's timezone | |
1185 | setting. Previously this has been done via a bind mount, but | |
1186 | since symlinks cannot be bind mounted this has now been | |
1187 | changed to create/update the appropriate symlink. | |
1188 | ||
1189 | * journalctl -n's line number argument is now optional, and | |
1190 | will default to 10 if omitted. | |
1191 | ||
1192 | * journald will now log the maximum size the journal files may | |
1193 | take up on disk. This is particularly useful if the default | |
1194 | built-in logic of determining this parameter from the file | |
1195 | system size is used. Use "systemctl status | |
6563b535 | 1196 | systemd-journald.service" to see this information. |
b6a86739 LP |
1197 | |
1198 | * The multi-seat X wrapper tool has been stripped down. As X | |
1199 | is now capable of enumerating graphics devices via udev in a | |
1200 | seat-aware way the wrapper is not strictly necessary | |
1201 | anymore. A stripped down temporary stop-gap is still shipped | |
1202 | until the upstream display managers have been updated to | |
1203 | fully support the new X logic. Expect this wrapper to be | |
6563b535 | 1204 | removed entirely in one of the next releases. |
b6a86739 LP |
1205 | |
1206 | * HandleSleepKey= in logind.conf has been split up into | |
1207 | HandleSuspendKey= and HandleHibernateKey=. The old setting | |
6563b535 | 1208 | is not available anymore. X11 and the kernel are |
b6a86739 LP |
1209 | distuingishing between these keys and we should too. This |
1210 | also means the inhibition lock for these keys has been split | |
1211 | into two. | |

0c11f949 LP |
1216 | CHANGES WITH 190: |
1217 | ||
1218 | * Whenever a unit changes state we'll now log this to the | |
1219 | journal and show along the unit's own log output in | |
1220 | "systemctl status". | |
1221 | ||
1222 | * ConditionPathIsMountPoint= can now properly detect bind | |
1223 | mount points too. (Previously, a bind mount of one file | |
8d0256b7 | 1224 | system to another place in the same file system could not be |
0c11f949 LP |
1225 | detected as mount, since they shared struct stat's st_dev |
1226 | field.) | |
1227 | ||
1228 | * We will now mount the cgroup controllers cpu, cpuacct, | |
1229 | cpuset and the controllers net_cls, net_prio together by | |
1230 | default. | |
1231 | ||
1232 | * nspawn containers will now have a virtualized boot | |
1233 | ID. (i.e. /proc/sys/kernel/random/boot_id is now mounted | |
1234 | over with a randomized ID at container initialization). This | |
1235 | has the effect of making "journalctl -b" do the right thing | |
1236 | in a container. | |
1237 | ||
1238 | * The JSON output journal serialization has been updated not | |
1239 | to generate "endless" list objects anymore, but rather one | |
1240 | JSON object per line. This is more in line how most JSON | |
1241 | parsers expect JSON objects. The new output mode | |
1242 | "json-pretty" has been added to provide similar output, but | |
1243 | neatly aligned for readability by humans. | |
1244 | ||
1245 | * We dropped all explicit sync() invocations in the shutdown | |
1246 | code. The kernel does this implicitly anyway in the kernel | |
1247 | reboot() syscall. halt(8)'s -n option is now a compatibility | |
1248 | no-op. | |
1249 | ||
1250 | * We now support virtualized reboot() in containers, as | |
1251 | supported by newer kernels. We will fall back to exit() if | |
1252 | CAP_SYS_REBOOT is not available to the container. Also, | |
1253 | nspawn makes use of this now and will actually reboot the | |
1254 | container if the containerized OS asks for that. | |
1255 | ||
1256 | * journalctl will only show local log output by default | |
1257 | now. Use --merge (-m) to show remote log output, too. | |
1258 | ||
1259 | * libsystemd-journal gained the new sd_journal_get_usage() | |
1260 | call to determine the current disk usage of all journal | |
1261 | files. This is exposed in the new "journalctl --disk-usage" | |
1262 | command. | |
1263 | ||
1264 | * journald gained a new configuration setting SplitMode= in | |
1265 | journald.conf which may be used to control how user journals | |
1266 | are split off. See journald.conf(5) for details. | |
1267 | ||
1268 | * A new condition type ConditionFileNotEmpty= has been added. | |
1269 | ||
1270 | * tmpfiles' "w" lines now support file globbing, to write | |
1271 | multiple files at once. | |
1272 | ||
1273 | * We added Python bindings for the journal submission | |
1274 | APIs. More Python APIs for a number of selected APIs will | |
1275 | likely follow. Note that we intend to add native bindings | |
1276 | only for the Python language, as we consider it common | |
1277 | enough to deserve bindings shipped within systemd. There are | |
1278 | various projects outside of systemd that provide bindings | |
1279 | for languages such as PHP or Lua. | |
1280 | ||
a98d5d64 LP |
1281 | * Many conditions will now resolve specifiers such as %i. In |
1282 | addition, PathChanged= and related directives of .path units | |
1283 | now support specifiers as well. | |
0c11f949 LP |
1284 | |
1285 | * There's now a new RPM macro definition for the system preset | |
1286 | dir: %_presetdir. | |
1287 | ||
ab06eef8 | 1288 | * journald will now warn if it can't forward a message to the |
0c11f949 LP |
1289 | syslog daemon because it's socket is full. |
1290 | ||
1291 | * timedated will no longer write or process /etc/timezone, | |
1292 | except on Debian. As we do not support late mounted /usr | |
1293 | anymore /etc/localtime always being a symlink is now safe, | |
1294 | and hence the information in /etc/timezone is not necessary | |
1295 | anymore. | |
1296 | ||
aaccc32c | 1297 | * logind will now always reserve one VT for a text getty (VT6 |
0c11f949 LP |
1298 | by default). Previously if more than 6 X sessions where |
1299 | started they took up all the VTs with auto-spawned gettys, | |
1300 | so that no text gettys were available anymore. | |
1301 | ||
1302 | * udev will now automatically inform the btrfs kernel logic | |
1303 | about btrfs RAID components showing up. This should make | |
1304 | simple hotplug based btrfs RAID assembly work. | |
1305 | ||
1306 | * PID 1 will now increase its RLIMIT_NOFILE to 64K by default | |
1307 | (but not for its children which will stay at the kernel | |
1308 | default). This should allow setups with a lot more listening | |
1309 | sockets. | |
1310 | ||
1311 | * systemd will now always pass the configured timezone to the | |
1312 | kernel at boot. timedated will do the same when the timezone | |
1313 | is changed. | |
1314 | ||
1315 | * logind's inhibition logic has been updated. By default, | |
1316 | logind will now handle the lid switch, the power and sleep | |
1317 | keys all the time, even in graphical sessions. If DEs want | |
1318 | to handle these events on their own they should take the new | |
1319 | handle-power-key, handle-sleep-key and handle-lid-switch | |
1320 | inhibitors during their runtime. A simple way to achiveve | |
1321 | that is to invoke the DE wrapped in an invocation of: | |
1322 | ||
1323 | systemd-inhibit --what=handle-power-key:handle-sleep-key:handle-lid-switch ... | |
1324 | ||
1325 | * Access to unit operations is now checked via SELinux taking | |
1326 | the unit file label and client process label into account. | |
1327 | ||
aad803af LP |
1328 | * systemd will now notify the administrator in the journal |
1329 | when he over-mounts a non-empty directory. | |
1330 | ||
1331 | * There are new specifiers that are resolved in unit files, | |
1332 | for the host name (%H), the machine ID (%m) and the boot ID | |
1333 | (%b). | |

1343 | CHANGES WITH 189: |
1344 | ||
1345 | * Support for reading structured kernel messages from | |
1346 | /dev/kmsg has now been added and is enabled by default. | |
1347 | ||
1348 | * Support for reading kernel messages from /proc/kmsg has now | |
1349 | been removed. If you want kernel messages in the journal | |
1350 | make sure to run a recent kernel (>= 3.5) that supports | |
1351 | reading structured messages from /dev/kmsg (see | |
1352 | above). /proc/kmsg is now exclusive property of classic | |
1353 | syslog daemons again. | |
1354 | ||
1355 | * The libudev API gained the new | |
1356 | udev_device_new_from_device_id() call. | |
1357 | ||
1358 | * The logic for file system namespace (ReadOnlyDirectory=, | |
1359 | ReadWriteDirectoy=, PrivateTmp=) has been reworked not to | |
1360 | require pivot_root() anymore. This means fewer temporary | |
1361 | directories are created below /tmp for this feature. | |
1362 | ||
1363 | * nspawn containers will now see and receive all submounts | |
1364 | made on the host OS below the root file system of the | |
1365 | container. | |
1366 | ||
1367 | * Forward Secure Sealing is now supported for Journal files, | |
1368 | which provide cryptographical sealing of journal files so | |
1369 | that attackers cannot alter log history anymore without this | |
1370 | being detectable. Lennart will soon post a blog story about | |
1371 | this explaining it in more detail. | |
1372 | ||
1373 | * There are two new service settings RestartPreventExitStatus= | |
1374 | and SuccessExitStatus= which allow configuration of exit | |
1375 | status (exit code or signal) which will be excepted from the | |
1376 | restart logic, resp. consider successful. | |
1377 | ||
1378 | * journalctl gained the new --verify switch that can be used | |
1379 | to check the integrity of the structure of journal files and | |
1380 | (if Forward Secure Sealing is enabled) the contents of | |
1381 | journal files. | |
1382 | ||
1383 | * nspawn containers will now be run with /dev/stdin, /dev/fd/ | |
1384 | and similar symlinks pre-created. This makes running shells | |
1385 | as container init process a lot more fun. | |
1386 | ||
1387 | * The fstab support can now handle PARTUUID= and PARTLABEL= | |
1388 | entries. | |
1389 | ||
1390 | * A new ConditionHost= condition has been added to match | |
1391 | against the hostname (with globs) and machine ID. This is | |
1392 | useful for clusters where a single OS image is used to | |
1393 | provision a large number of hosts which shall run slightly | |
1394 | different sets of services. | |
1395 | ||
1396 | * Services which hit the restart limit will now be placed in a | |
1397 | failure state. | |

c269cec3 LP |
1403 | CHANGES WITH 188: |
1404 | ||
1405 | * When running in --user mode systemd will now become a | |
1406 | subreaper (PR_SET_CHILD_SUBREAPER). This should make the ps | |
1407 | tree a lot more organized. | |
1408 | ||
1409 | * A new PartOf= unit dependency type has been introduced that | |
1410 | may be used to group services in a natural way. | |
1411 | ||
1412 | * "systemctl enable" may now be used to enable instances of | |
1413 | services. | |
1414 | ||
1415 | * journalctl now prints error log levels in red, and | |
1416 | warning/notice log levels in bright white. It also supports | |
1417 | filtering by log level now. | |
1418 | ||
1419 | * cgtop gained a new -n switch (similar to top), to configure | |
1420 | the maximum number of iterations to run for. It also gained | |
1421 | -b, to run in batch mode (accepting no input). | |
1422 | ||
ab06eef8 | 1423 | * The suffix ".service" may now be omitted on most systemctl |
c269cec3 LP |
1424 | command lines involving service unit names. |
1425 | ||
1426 | * There's a new bus call in logind to lock all sessions, as | |
1427 | well as a loginctl verb for it "lock-sessions". | |
1428 | ||
1429 | * libsystemd-logind.so gained a new call sd_journal_perror() | |
1430 | that works similar to libc perror() but logs to the journal | |
1431 | and encodes structured information about the error number. | |
1432 | ||
1433 | * /etc/crypttab entries now understand the new keyfile-size= | |
1434 | option. | |
1435 | ||
1436 | * shutdown(8) now can send a (configurable) wall message when | |
1437 | a shutdown is cancelled. | |
1438 | ||
1439 | * The mount propagation mode for the root file system will now | |
1440 | default to "shared", which is useful to make containers work | |
1441 | nicely out-of-the-box so that they receive new mounts from | |
1442 | the host. This can be undone locally by running "mount | |
1443 | --make-rprivate /" if needed. | |
1444 | ||
1445 | * The prefdm.service file has been removed. Distributions | |
1446 | should maintain this unit downstream if they intend to keep | |
1447 | it around. However, we recommend writing normal unit files | |
1448 | for display managers instead. | |
1449 | ||
1450 | * Since systemd is a crucial part of the OS we will now | |
1451 | default to a number of compiler switches that improve | |
1452 | security (hardening) such as read-only relocations, stack | |
1453 | protection, and suchlike. | |
1454 | ||
1455 | * The TimeoutSec= setting for services is now split into | |
1456 | TimeoutStartSec= and TimeoutStopSec= to allow configuration | |
1457 | of individual time outs for the start and the stop phase of | |
1458 | the service. | |

c4f1b862 LP |
1467 | CHANGES WITH 187: |
1468 | ||
1469 | * The journal and id128 C APIs are now fully documented as man | |
1470 | pages. | |
1471 | ||
1472 | * Extra safety checks have been added when transitioning from | |
1473 | the initial RAM disk to the main system to avoid accidental | |
1474 | data loss. | |
1475 | ||
c269cec3 | 1476 | * /etc/crypttab entries now understand the new keyfile-offset= |
c4f1b862 LP |
1477 | option. |
1478 | ||
1479 | * systemctl -t can now be used to filter by unit load state. | |
1480 | ||
1481 | * The journal C API gained the new sd_journal_wait() call to | |
1482 | make writing synchronous journal clients easier. | |
1483 | ||
1484 | * journalctl gained the new -D switch to show journals from a | |
1485 | specific directory. | |
1486 | ||
1487 | * journalctl now displays a special marker between log | |
1488 | messages of two different boots. | |
1489 | ||
1490 | * The journal is now explicitly flushed to /var via a service | |
1491 | systemd-journal-flush.service, rather than implicitly simply | |
1492 | by seeing /var/log/journal to be writable. | |
1493 | ||
1494 | * journalctl (and the journal C APIs) can now match for much | |
1495 | more complex expressions, with alternatives and | |
1496 | disjunctions. | |
1497 | ||
1498 | * When transitioning from the initial RAM disk to the main | |
1499 | system we will now kill all processes in a killing spree to | |
1500 | ensure no processes stay around by accident. | |
1501 | ||
1502 | * Three new specifiers may be used in unit files: %u, %h, %s | |
1503 | resolve to the user name, user home directory resp. user | |
1504 | shell. This is useful for running systemd user instances. | |
1505 | ||
1506 | * We now automatically rotate journal files if their data | |
1507 | object hash table gets a fill level > 75%. We also size the | |
1508 | hash table based on the configured maximum file size. This | |
1509 | together should lower hash collisions drastically and thus | |
1510 | speed things up a bit. | |
1511 | ||
1512 | * journalctl gained the new "--header" switch to introspect | |
1513 | header data of journal files. | |
1514 | ||
1515 | * A new setting SystemCallFilters= has been added to services | |
1516 | which may be used to apply blacklists or whitelists to | |
1517 | system calls. This is based on SECCOMP Mode 2 of Linux 3.5. | |
1518 | ||
1519 | * nspawn gained a new --link-journal= switch (and quicker: -j) | |
1520 | to link the container journal with the host. This makes it | |
1521 | very easy to centralize log viewing on the host for all | |
1522 | guests while still keeping the journal files separated. | |
1523 | ||
1524 | * Many bugfixes and optimizations | |

b5b4c94a LP |
1531 | CHANGES WITH 186: |
1532 | ||
1533 | * Several tools now understand kernel command line arguments, | |
1534 | which are only read when run in an initial RAM disk. They | |
1535 | usually follow closely their normal counterparts, but are | |
1536 | prefixed with rd. | |
1537 | ||
1538 | * There's a new tool to analyze the readahead files that are | |
1539 | automatically generated at boot. Use: | |
1540 | ||
1541 | /usr/lib/systemd/systemd-readahead analyze /.readahead | |
1542 | ||
1543 | * We now provide an early debug shell on tty9 if this enabled. Use: | |
1544 | ||
d1f9edaf | 1545 | systemctl enable debug-shell.service |
b5b4c94a LP |
1546 | |
1547 | * All plymouth related units have been moved into the Plymouth | |
1548 | package. Please make sure to upgrade your Plymouth version | |
1549 | as well. | |
1550 | ||
1551 | * systemd-tmpfiles now supports getting passed the basename of | |
1552 | a configuration file only, in which case it will look for it | |
1553 | in all appropriate directories automatically. | |
1554 | ||
1555 | * udevadm info now takes a /dev or /sys path as argument, and | |
1556 | does the right thing. Example: | |
1557 | ||
1558 | udevadm info /dev/sda | |
1559 | udevadm info /sys/class/block/sda | |
1560 | ||
1561 | * systemctl now prints a warning if a unit is stopped but a | |
1562 | unit that might trigger it continues to run. Example: a | |
1563 | service is stopped but the socket that activates it is left | |
1564 | running. | |
1565 | ||
1566 | * "systemctl status" will now mention if the log output was | |
1567 | shortened due to rotation since a service has been started. | |
1568 | ||
1569 | * The journal API now exposes functions to determine the | |
1570 | "cutoff" times due to rotation. | |
1571 | ||
1572 | * journald now understands SIGUSR1 and SIGUSR2 for triggering | |
1573 | immediately flushing of runtime logs to /var if possible, | |
1574 | resp. for triggering immediate rotation of the journal | |
1575 | files. | |
1576 | ||
1577 | * It is now considered an error if a service is attempted to | |
1578 | be stopped that is not loaded. | |
1579 | ||
1580 | * XDG_RUNTIME_DIR now uses numeric UIDs instead of usernames. | |
1581 | ||
1582 | * systemd-analyze now supports Python 3 | |
1583 | ||
1584 | * tmpfiles now supports cleaning up directories via aging | |
1585 | where the first level dirs are always kept around but | |
1586 | directories beneath it automatically aged. This is enabled | |
1587 | by prefixing the age field with '~'. | |
1588 | ||
1589 | * Seat objects now expose CanGraphical, CanTTY properties | |
1590 | which is required to deal with very fast bootups where the | |
1591 | display manager might be running before the graphics drivers | |
1592 | completed initialization. | |
1593 | ||
1594 | * Seat objects now expose a State property. | |
1595 | ||
1596 | * We now include RPM macros for service enabling/disabling | |
1597 | based on the preset logic. We recommend RPM based | |
1598 | distributions to make use of these macros if possible. This | |
1599 | makes it simpler to reuse RPM spec files across | |
1600 | distributions. | |
1601 | ||
1602 | * We now make sure that the collected systemd unit name is | |
1603 | always valid when services log to the journal via | |
1604 | STDOUT/STDERR. | |
1605 | ||
1606 | * There's a new man page kernel-command-line(7) detailing all | |
1607 | command line options we understand. | |
1608 | ||
1609 | * The fstab generator may now be disabled at boot by passing | |
1610 | fstab=0 on the kernel command line. | |
1611 | ||
91ac7425 | 1612 | * A new kernel command line option modules-load= is now understood |
b5b4c94a LP |
1613 | to load a specific kernel module statically, early at boot. |
1614 | ||
1615 | * Unit names specified on the systemctl command line are now | |
1616 | automatically escaped as needed. Also, if file system or | |
1617 | device paths are specified they are automatically turned | |
1618 | into the appropriate mount or device unit names. Example: | |
1619 | ||
1620 | systemctl status /home | |
1621 | systemctl status /dev/sda | |
1622 | ||
1623 | * The SysVConsole= configuration option has been removed from | |
1624 | system.conf parsing. | |
1625 | ||
1626 | * The SysV search path is no longer exported on the D-Bus | |
1627 | Manager object. | |
1628 | ||
1629 | * The Names= option is been removed from unit file parsing. | |
1630 | ||
1631 | * There's a new man page bootup(7) detailing the boot process. | |
1632 | ||
1633 | * Every unit and every generator we ship with systemd now | |
1634 | comes with full documentation. The self-explanatory boot is | |
1635 | complete. | |
1636 | ||
1637 | * A couple of services gained "systemd-" prefixes in their | |
1638 | name if they wrap systemd code, rather than only external | |
1639 | code. Among them fsck@.service which is now | |
1640 | systemd-fsck@.service. | |
1641 | ||
1642 | * The HaveWatchdog property has been removed from the D-Bus | |
1643 | Manager object. | |
1644 | ||
1645 | * systemd.confirm_spawn= on the kernel command line should now | |
1646 | work sensibly. | |
1647 | ||
1648 | * There's a new man page crypttab(5) which details all options | |
1649 | we actually understand. | |
1650 | ||
1651 | * systemd-nspawn gained a new --capability= switch to pass | |
1652 | additional capabilities to the container. | |
1653 | ||
1654 | * timedated will now read known NTP implementation unit names | |
5b00c016 | 1655 | from /usr/lib/systemd/ntp-units.d/*.list, |
b5b4c94a LP |
1656 | systemd-timedated-ntp.target has been removed. |
1657 | ||
1658 | * journalctl gained a new switch "-b" that lists log data of | |
1659 | the current boot only. | |
1660 | ||
1661 | * The notify socket is in the abstract namespace again, in | |
1662 | order to support daemons which chroot() at start-up. | |
1663 | ||
1664 | * There is a new Storage= configuration option for journald | |
1665 | which allows configuration of where log data should go. This | |
1666 | also provides a way to disable journal logging entirely, so | |
1667 | that data collected is only forwarded to the console, the | |
1668 | kernel log buffer or another syslog implementation. | |
1669 | ||
c4f1b862 | 1670 | * Many bugfixes and optimizations |

1698 | * logind is now capable of (optionally) handling power and |
1699 | sleep keys as well as the lid switch. | |
1700 | ||
1701 | * journalctl now understands the syntax "journalctl | |
1702 | /usr/bin/avahi-daemon" to get all log output of a specific | |
1703 | daemon. | |
1704 | ||
1705 | * CapabilityBoundingSet= in system.conf now also influences | |

ea5943d3 | 1713 | CHANGES WITH 183: |
b6a86739 | 1714 | |
187076d4 LP |
1715 | * Note that we skipped 139 releases here in order to set the |
1716 | new version to something that is greater than both udev's | |
1717 | and systemd's most recent version number. | |
1718 | ||
194bbe33 KS |
1719 | * udev: all udev sources are merged into the systemd source tree now. |
1720 | All future udev development will happen in the systemd tree. It | |
1721 | is still fully supported to use the udev daemon and tools without | |
1722 | systemd running, like in initramfs or other init systems. Building | |
1723 | udev though, will require the *build* of the systemd tree, but | |
ea5943d3 | 1724 | udev can be properly *run* without systemd. |
07cd4fc1 | 1725 | |
91cf7e5c | 1726 | * udev: /lib/udev/devices/ are not read anymore; systemd-tmpfiles |
f13b388f KS |
1727 | should be used to create dead device nodes as workarounds for broken |
1728 | subsystems. | |
64661ee7 | 1729 | |
2d13da88 KS |
1730 | * udev: RUN+="socket:..." and udev_monitor_new_from_socket() is |
1731 | no longer supported. udev_monitor_new_from_netlink() needs to be | |
1732 | used to subscribe to events. | |
1733 | ||
194bbe33 KS |
1734 | * udev: when udevd is started by systemd, processes which are left |
1735 | behind by forking them off of udev rules, are unconditionally cleaned | |
1736 | up and killed now after the event handling has finished. Services or | |
1737 | daemons must be started as systemd services. Services can be | |
ea5943d3 | 1738 | pulled-in by udev to get started, but they can no longer be directly |
194bbe33 KS |
1739 | forked by udev rules. |
1740 | ||
f13b388f KS |
1741 | * udev: the daemon binary is called systemd-udevd now and installed |
1742 | in /usr/lib/systemd/. Standalone builds or non-systemd systems need | |
1743 | to adapt to that, create symlink, or rename the binary after building | |
1744 | it. | |
1745 | ||
ea5943d3 | 1746 | * libudev no longer provides these symbols: |
c1959569 KS |
1747 | udev_monitor_from_socket() |
1748 | udev_queue_get_failed_list_entry() | |
1749 | udev_get_{dev,sys,run}_path() | |
ea5943d3 | 1750 | The versions number was bumped and symbol versioning introduced. |
c1959569 | 1751 | |
ea5943d3 | 1752 | * systemd-loginctl and systemd-journalctl have been renamed |
9ae9afce | 1753 | to loginctl and journalctl to match systemctl. |
18b754d3 KS |
1754 | |
1755 | * The config files: /etc/systemd/systemd-logind.conf and | |
1756 | /etc/systemd/systemd-journald.conf have been renamed to | |
1757 | logind.conf and journald.conf. Package updates should rename | |
1758 | the files to the new names on upgrade. | |
1759 | ||
ea5943d3 LP |
1760 | * For almost all files the license is now LGPL2.1+, changed |
1761 | from the previous GPL2.0+. Exceptions are some minor stuff | |
1762 | of udev (which will be changed to LGPL2.1 eventually, too), | |
1763 | and the MIT licensed sd-daemon.[ch] library that is suitable | |
1764 | to be used as drop-in files. | |
1765 | ||
1766 | * systemd and logind now handle system sleep states, in | |
49f43d5f | 1767 | particular suspending and hibernating. |
ea5943d3 LP |
1768 | |
1769 | * logind now implements a sleep/shutdown/idle inhibiting logic | |
1770 | suitable for a variety of uses. Soonishly Lennart will blog | |
1771 | about this in more detail. | |
1772 | ||
1773 | * var-run.mount and var-lock.mount are no longer provided | |
1774 | (which prevously bind mounted these directories to their new | |
1775 | places). Distributions which have not converted these | |
1776 | directories to symlinks should consider stealing these files | |
1777 | from git history and add them downstream. | |
1778 | ||
1779 | * We introduced the Documentation= field for units and added | |
1780 | this to all our shipped units. This is useful to make it | |
3943231c | 1781 | easier to explore the boot and the purpose of the various |
ea5943d3 LP |
1782 | units. |
1783 | ||
1784 | * All smaller setup units (such as | |
1785 | systemd-vconsole-setup.service) now detect properly if they | |
1786 | are run in a container and are skipped when | |
1787 | appropriate. This guarantees an entirely noise-free boot in | |
1788 | Linux container environments such as systemd-nspawn. | |
1789 | ||
1790 | * A framework for implementing offline system updates is now | |
1791 | integrated, for details see: | |
1792 | http://freedesktop.org/wiki/Software/systemd/SystemUpdates | |
1793 | ||
1794 | * A new service type Type=idle is available now which helps us | |
1795 | avoiding ugly interleaving of getty output and boot status | |
1796 | messages. | |
1797 | ||
439d6dfd LP |
1798 | * There's now a system-wide CapabilityBoundingSet= option to |
1799 | globally reduce the set of capabilities for the | |
ea5943d3 LP |
1800 | system. This is useful to drop CAP_SYS_MKNOD, CAP_SYS_RAWIO, |
1801 | CAP_NET_RAW, CAP_SYS_MODULE, CAP_SYS_TIME, CAP_SYS_PTRACE or | |
1802 | even CAP_NET_ADMIN system-wide for secure systems. | |
1803 | ||
1804 | * There are now system-wide DefaultLimitXXX= options to | |
1805 | globally change the defaults of the various resource limits | |
1806 | for all units started by PID 1. | |
1807 | ||
1808 | * Harald Hoyer's systemd test suite has been integrated into | |
1809 | systemd which allows easy testing of systemd builds in qemu | |
1810 | and nspawn. (This is really awesome! Ask us for details!) | |
1811 | ||
3943231c LP |
1812 | * The fstab parser is now implemented as generator, not inside |
1813 | of PID 1 anymore. | |
ea5943d3 LP |
1814 | |
1815 | * systemctl will now warn you if .mount units generated from | |
1816 | /etc/fstab are out of date due to changes in fstab that | |
1817 | haven't been read by systemd yet. | |
1818 | ||
1819 | * systemd is now suitable for usage in initrds. Dracut has | |
1820 | already been updated to make use of this. With this in place | |
1821 | initrds get a slight bit faster but primarily are much | |
1822 | easier to introspect and debug since "systemctl status" in | |
1823 | the host system can be used to introspect initrd services, | |
1824 | and the journal from the initrd is kept around too. | |
1825 | ||
1826 | * systemd-delta has been added, a tool to explore differences | |
1827 | between user/admin configuration and vendor defaults. | |
1828 | ||
1829 | * PrivateTmp= now affects both /tmp and /var/tmp. | |
1830 | ||
1831 | * Boot time status messages are now much prettier and feature | |
1832 | proper english language. Booting up systemd has never been | |
1833 | so sexy. | |
1834 | ||
1835 | * Read-ahead pack files now include the inode number of all | |
1836 | files to pre-cache. When the inode changes the pre-caching | |
1837 | is not attempted. This should be nicer to deal with updated | |
1838 | packages which might result in changes of read-ahead | |
1839 | patterns. | |
1840 | ||
1841 | * We now temporaritly lower the kernel's read_ahead_kb variable | |
1842 | when collecting read-ahead data to ensure the kernel's | |
1843 | built-in read-ahead does not add noise to our measurements | |
1844 | of necessary blocks to pre-cache. | |
1845 | ||
1846 | * There's now RequiresMountsFor= to add automatic dependencies | |
1847 | for all mounts necessary for a specific file system path. | |
1848 | ||
1849 | * MountAuto= and SwapAuto= have been removed from | |
1850 | system.conf. Mounting file systems at boot has to take place | |
1851 | in systemd now. | |
1852 | ||
1853 | * nspawn now learned a new switch --uuid= to set the machine | |
1854 | ID on the command line. | |
1855 | ||
f8c0a2cb | 1856 | * nspawn now learned the -b switch to automatically search |
ea5943d3 LP |
1857 | for an init system. |
1858 | ||
1859 | * vt102 is now the default TERM for serial TTYs, upgraded from | |
1860 | vt100. | |
1861 | ||
1862 | * systemd-logind now works on VT-less systems. | |
1863 | ||
1864 | * The build tree has been reorganized. The individual | |
3943231c | 1865 | components now have directories of their own. |
ea5943d3 LP |
1866 | |
1867 | * A new condition type ConditionPathIsReadWrite= is now available. | |
1868 | ||
1869 | * nspawn learned the new -C switch to create cgroups for the | |
1870 | container in other hierarchies. | |
1871 | ||
1872 | * We now have support for hardware watchdogs, configurable in | |
1873 | system.conf. | |
1874 | ||
1875 | * The scheduled shutdown logic now has a public API. | |
1876 | ||
1877 | * We now mount /tmp as tmpfs by default, but this can be | |
1878 | masked and /etc/fstab can override it. | |
1879 | ||
1880 | * Since udisks doesn't make use of /media anymore we are not | |
1881 | mounting a tmpfs on it anymore. | |
1882 | ||
1883 | * journalctl gained a new --local switch to only interleave | |
1884 | locally generated journal files. | |
1885 | ||
1886 | * We can now load the IMA policy at boot automatically. | |
1887 | ||
1888 | * The GTK tools have been split off into a systemd-ui. | |

16f1239e | 1901 | CHANGES WITH 44: |
b6a86739 | 1902 | |
16f1239e LP |
1903 | * This is mostly a bugfix release |
1904 | ||
1905 | * Support optional initialization of the machine ID from the | |
1906 | KVM or container configured UUID. | |
1907 | ||
1908 | * Support immediate reboots with "systemctl reboot -ff" | |
1909 | ||
1910 | * Show /etc/os-release data in systemd-analyze output | |
1911 | ||
ab06eef8 | 1912 | * Many bugfixes for the journal, including endianness fixes and |
16f1239e LP |
1913 | ensuring that disk space enforcement works |
1914 | ||
1915 | * sd-login.h is C++ comptaible again | |
1916 | ||
1917 | * Extend the /etc/os-release format on request of the Debian | |
1918 | folks | |
1919 | ||
1920 | * We now refuse non-UTF8 strings used in various configuration | |
1921 | and unit files. This is done to ensure we don't pass invalid | |
1922 | data over D-Bus or expose it elsewhere. | |
1923 | ||
1924 | * Register Mimo USB Screens as suitable for automatic seat | |
1925 | configuration | |
1926 | ||
1927 | * Read SELinux client context from journal clients in a race | |
1928 | free fashion | |
1929 | ||
1930 | * Reorder configuration file lookup order. /etc now always | |
1931 | overrides /run in order to allow the administrator to always | |
1932 | and unconditionally override vendor supplied or | |
1933 | automatically generated data. | |
1934 | ||
1935 | * The various user visible bits of the journal now have man | |
1936 | pages. We still lack man pages for the journal API calls | |
1937 | however. | |
1938 | ||
1939 | * We now ship all man pages in HTML format again in the | |
1940 | tarball. | |

b6a86739 | 1948 | |
437b7dee LP |
1949 | * This is mostly a bugfix release |
1950 | ||
1951 | * systems lacking /etc/os-release are no longer supported. | |
1952 | ||
1953 | * Various functionality updates to libsystemd-login.so | |
1954 | ||
1955 | * Track class of PAM logins to distuingish greeters from | |
1956 | normal user logins. | |

b6a86739 | 1962 | |
204fa33c LP |
1963 | * This is an important bugfix release for v41. |
1964 | ||
1965 | * Building man pages is now optional which should be useful | |
1966 | for those building systemd from git but unwilling to install | |
1967 | xsltproc. | |
1968 | ||
1969 | * Watchdog support for supervising services is now usable. In | |
1970 | a future release support for hardware watchdogs | |
1971 | (i.e. /dev/watchdog) will be added building on this. | |
1972 | ||
1973 | * Service start rate limiting is now configurable and can be | |
1974 | turned off per service. When a start rate limit is hit a | |
1975 | reboot can automatically be triggered. | |
1976 | ||
1977 | * New CanReboot(), CanPowerOff() bus calls in systemd-logind. | |

e0d25329 | 1983 | CHANGES WITH 41: |
b6a86739 | 1984 | |
e0d25329 KS |
1985 | * The systemd binary is installed /usr/lib/systemd/systemd now; |
1986 | An existing /sbin/init symlink needs to be adapted with the | |
1987 | package update. | |
1988 | ||
b13df964 LP |
1989 | * The code that loads kernel modules has been ported to invoke |
1990 | libkmod directly, instead of modprobe. This means we do not | |
1991 | support systems with module-init-tools anymore. | |
1992 | ||
1993 | * Watchdog support is now already useful, but still not | |
1994 | complete. | |
1995 | ||
1996 | * A new kernel command line option systemd.setenv= is | |
1997 | understood to set system wide environment variables | |
1998 | dynamically at boot. | |
1999 | ||
e9c1ea9d | 2000 | * We now limit the set of capabilities of systemd-journald. |
ccd07a08 | 2001 | |
353e12c2 LP |
2002 | * We now set SIGPIPE to ignore by default, since it only is |
2003 | useful in shell pipelines, and has little use in general | |
2004 | code. This can be disabled with IgnoreSIPIPE=no in unit | |
2005 | files. | |

b6a86739 | 2012 | |
d26e4270 LP |
2013 | * This is mostly a bugfix release |
2014 | ||
2015 | * We now expose the reason why a service failed in the | |
2016 | "Result" D-Bus property. | |
2017 | ||
2018 | * Rudimentary service watchdog support (will be completed over | |
2019 | the next few releases.) | |
2020 | ||
2021 | * When systemd forks off in order execute some service we will | |
2022 | now immediately changes its argv[0] to reflect which process | |
2023 | it will execute. This is useful to minimize the time window | |
2024 | with a generic argv[0], which makes bootcharts more useful | |

220a21d3 | 2030 | CHANGES WITH 39: |
b6a86739 | 2031 | |
220a21d3 LP |
2032 | * This is mostly a test release, but incorporates many |
2033 | bugfixes. | |
2034 | ||
2035 | * New systemd-cgtop tool to show control groups by their | |
2036 | resource usage. | |
2037 | ||
2038 | * Linking against libacl for ACLs is optional again. If | |
2039 | disabled, support tracking device access for active logins | |
2040 | goes becomes unavailable, and so does access to the user | |
2041 | journals by the respective users. | |
2042 | ||
2043 | * If a group "adm" exists, journal files are automatically | |
2044 | owned by them, thus allow members of this group full access | |
2045 | to the system journal as well as all user journals. | |
2046 | ||
2047 | * The journal now stores the SELinux context of the logging | |
2048 | client for all entries. | |
2049 | ||
2050 | * Add C++ inclusion guards to all public headers | |
2051 | ||
2052 | * New output mode "cat" in the journal to print only text | |
2053 | messages, without any meta data like date or time. | |
2054 | ||
2055 | * Include tiny X server wrapper as a temporary stop-gap to | |
2056 | teach XOrg udev display enumeration. This is used by display | |
2057 | managers such as gdm, and will go away as soon as XOrg | |
2058 | learned native udev hotplugging for display devices. | |
2059 | ||
2060 | * Add new systemd-cat tool for executing arbitrary programs | |
2061 | with STDERR/STDOUT connected to the journal. Can also act as | |
2062 | BSD logger replacement, and does so by default. | |
2063 | ||
2064 | * Optionally store all locally generated coredumps in the | |
2065 | journal along with meta data. | |
2066 | ||
2067 | * systemd-tmpfiles learnt four new commands: n, L, c, b, for | |
2068 | writing short strings to files (for usage for /sys), and for | |
2069 | creating symlinks, character and block device nodes. | |
2070 | ||
2071 | * New unit file option ControlGroupPersistent= to make cgroups | |
2072 | persistent, following the mechanisms outlined in | |
2073 | http://www.freedesktop.org/wiki/Software/systemd/PaxControlGroups | |
2074 | ||
2075 | * Support multiple local RTCs in a sane way | |
2076 | ||
2077 | * No longer monopolize IO when replaying readahead data on | |
2078 | rotating disks, since we might starve non-file-system IO to | |
2079 | death, since fanotify() will not see accesses done by blkid, | |
2080 | or fsck. | |
2081 | ||
2082 | * Don't show kernel threads in systemd-cgls anymore, unless | |
2083 | requested with new -k switch. | |

2088 | CHANGES WITH 38: | |
b6a86739 | 2089 | |
220a21d3 LP |
2090 | * This is mostly a test release, but incorporates many |
2091 | bugfixes. | |
2092 | ||
2093 | * The git repository moved to: | |
2094 | git://anongit.freedesktop.org/systemd/systemd | |
2095 | ssh://git.freedesktop.org/git/systemd/systemd | |
2096 | ||
2097 | * First release with the journal | |
2098 | http://0pointer.de/blog/projects/the-journal.html | |
2099 | ||
2100 | * The journal replaces both systemd-kmsg-syslogd and | |
2101 | systemd-stdout-bridge. | |
2102 | ||
2103 | * New sd_pid_get_unit() API call in libsystemd-logind | |
2104 | ||
2105 | * Many systemadm clean-ups | |
2106 | ||
2107 | * Introduce remote-fs-pre.target which is ordered before all | |
2108 | remote mounts and may be used to start services before all | |
2109 | remote mounts. | |
2110 | ||
2111 | * Added Mageia support | |
2112 | ||
2113 | * Add bash completion for systemd-loginctl | |
2114 | ||
2115 | * Actively monitor PID file creation for daemons which exit in | |
2116 | the parent process before having finished writing the PID | |
2117 | file in the daemon process. Daemons which do this need to be | |
2118 | fixed (i.e. PID file creation must have finished before the | |
2119 | parent exits), but we now react a bit more gracefully to them. | |
2120 | ||
2121 | * Add colourful boot output, mimicking the well-known output | |
2122 | of existing distributions. | |
2123 | ||
2124 | * New option PassCredentials= for socket units, for | |
2125 | compatibility with a recent kernel ABI breakage. | |
2126 | ||
2127 | * /etc/rc.local is now hooked in via a generator binary, and | |
2128 | thus will no longer act as synchronization point during | |
2129 | boot. | |
2130 | ||
2131 | * systemctl list-unit-files now supports --root=. | |
2132 | ||
2133 | * systemd-tmpfiles now understands two new commands: z, Z for | |
2134 | relabelling files according to the SELinux database. This is | |
2135 | useful to apply SELinux labels to specific files in /sys, | |
2136 | among other things. | |
2137 | ||
2138 | * Output of SysV services is now forwarded to both the console | |
2139 | and the journal by default, not only just the console. | |
2140 | ||
2141 | * New man pages for all APIs from libsystemd-login. | |
2142 | ||
2143 | * The build tree got reorganized and a the build system is a | |
2144 | lot more modular allowing embedded setups to specifically | |
2145 | select the components of systemd they are interested in. | |
2146 | ||
2147 | * Support for Linux systems lacking the kernel VT subsystem is | |
2148 | restored. | |
2149 | ||
2150 | * configure's --with-rootdir= got renamed to | |
2151 | --with-rootprefix= to follow the naming used by udev and | |
2152 | kmod | |
2153 | ||
2154 | * Unless specified otherwise we'll now install to /usr instead | |
2155 | of /usr/local by default. | |
2156 | ||
2157 | * Processes with '@' in argv[0][0] are now excluded from the | |
2158 | final shut-down killing spree, following the logic explained | |
2159 | in: | |
2160 | http://www.freedesktop.org/wiki/Software/systemd/RootStorageDaemons | |
2161 | ||
2162 | * All processes remaining in a service cgroup when we enter | |
2163 | the START or START_PRE states are now killed with | |
2164 | SIGKILL. That means it is no longer possible to spawn | |
2165 | background processes from ExecStart= lines (which was never | |
2166 | supported anyway, and bad style). | |
2167 | ||
2168 | * New PropagateReloadTo=/PropagateReloadFrom= options to bind | |
2169 | reloading of units together. | |
