3 | CHANGES WITH 210: |
4 | ||
5 | * systemd will now relabel /dev after loading the SMACK policy | |
6 | according to SMACK rules. | |
7 | ||
8 | * A new unit file option AppArmoreProfile= has been added to | |
9 | set the AppArmor profile for the processes of a unit. | |
10 | ||
11 | * A new condition check ConditionArchitecture= has been added | |
12 | to conditionalize units based on the system architecture, as | |
13 | reported by uname()'s "machine" field. | |
14 | ||
15 | * systemd-networkd now supports matching on the system | |
16 | virtualization, architecture, kernel command line, host name | |
17 | and machine ID. | |
18 | ||
19 | * logind is now a lot more agressive when suspending the | |
20 | machine due to a closed laptop lid. Instead of acting only | |
21 | on the lid close action it will continously watch the lid | |
22 | status and act on it. This is useful for laptops where the | |
23 | power button is on the outside of the chassis so that it can | |
24 | be reached whithout opening the lid (such as the Lenovo | |
25 | Yoga). On those machines logind will now immediately | |
26 | resuspend the machine if the power button has been | |
27 | accidentally pressed while the laptop was suspended and in a | |
28 | backpack or similar. | |
29 | ||
30 | * logind will now watch SW_DOCK switches and inhibit reaction | |
31 | to the lid switch if it is pressed. This means that logind | |
32 | will not suspend the machine if the lid is closed and the | |
33 | systemd is docked anymore, if the laptop supports SW_DOCK | |
34 | notifications via the input layer. Note that ACPI docking | |
35 | stations do not generate this currently. Also note that this | |
36 | logic is usually not fully sufficient and Desktop | |
37 | Environments should take a lid switch inhibitor lock when an | |
38 | external display is connected, as systemd will not watch | |
39 | this on its own. | |
40 | ||
41 | * nspawn will now make use of the devices cgroup controller by | |
42 | default, and only permit creation of and access to the usual | |
43 | API device nodes like /dev/null or /dev/random, as well as | |
44 | access to (but not creation of) the pty devices. | |
45 | ||
46 | * We will now ship a default .network file for | |
47 | systemd-networkd that automatically configures DHCP for | |
48 | network interfaces created by nspawn's --network-veth or | |
49 | --network-bridge= switches. | |
50 | ||
51 | * systemd will now understand the usual M, K, G, T suffixes | |
52 | according to SI conventions (i.e. to the base 1000) when | |
53 | referring to throughput and hardware metrics. It will stay | |
54 | with IEC conventions (i.e. to the base 1024) for software | |
55 | metrics, according to what is customary according to | |
56 | Wikipedia. We explicitly document which base applies for | |
57 | each configuration option. | |
58 | ||
59 | * The DeviceAllow= setting in unit files now supports a syntax | |
60 | to whitelist an entire group of devince node majors at once, | |
61 | based on the /proc/devices listing. For example, with the | |
62 | string "char-pts" it is now possible to whitelist all | |
63 | current and future pseudo-TTYs at once. | |
64 | ||
65 | * sd-event learned a new "post" event source. Event sources of | |
66 | this type are triggered by the dispatching of any event | |
67 | source of a type that is not "post". This is useful for | |
68 | implementing clean-up and check event sources that are | |
69 | triggered by other work being done in the program. | |
70 | ||
71 | * systemd-networkd is no longer statically enabled, but uses | |
72 | the usual [Install] sections so that it can be | |
73 | enabled/disabled using systemctl. It still is enabled by | |
74 | default however. | |
75 | ||
76 | * When creating a veth interface pair with systemd-nspawn the | |
77 | host side will now be prefixed with "vb-" if | |
78 | --network-bridge= is used, and with "ve-" if --network-veth | |
79 | is used. This way it is easy to distuingish these cases on | |
80 | the host, for example to apply different configuration to | |
81 | them with systemd-networkd. | |

94 | CHANGES WITH 209: |
95 | ||
96 | * A new component "systemd-networkd" has been added that can | |
97 | be used to configure local network interfaces statically or | |
8b7d0494 JSJ |
98 | via DHCP. It is capable of bringing up bridges, VLANs, and |
99 | bonding. Currently, no hook-ups for interactive network | |
4670e9d5 | 100 | configuration are provided. Use this for your initrd, |
8b7d0494 JSJ |
101 | container, embedded, or server setup if you need a simple, |
102 | yet powerful, network configuration solution. This | |
4670e9d5 | 103 | configuration subsystem is quite nifty, as it allows wildcard |
1e190502 | 104 | hotplug matching in interfaces. For example, with a single |
4670e9d5 | 105 | configuration snippet, you can configure that all Ethernet |
1e190502 ZJS |
106 | interfaces showing up are automatically added to a bridge, |
107 | or similar. It supports link-sensing and more. | |
e49b5aad LP |
108 | |
109 | * A new tool "systemd-socket-proxyd" has been added which can | |
4c2413bf | 110 | act as a bidirectional proxy for TCP sockets. This is |
e49b5aad LP |
111 | useful for adding socket activation support to services that |
112 | do not actually support socket activation, including virtual | |
4c2413bf | 113 | machines and the like. |
e49b5aad LP |
114 | |
115 | * Add a new tool to save/restore rfkill state on | |
116 | shutdown/boot. | |
117 | ||
8b7d0494 JSJ |
118 | * Save/restore state of keyboard backlights in addition to |
119 | display backlights on shutdown/boot. | |
e49b5aad LP |
120 | |
121 | * udev learned a new SECLABEL{} construct to label device | |
122 | nodes with a specific security label when they appear. For | |
4c2413bf | 123 | now, only SECLABEL{selinux} is supported, but the syntax is |
e49b5aad LP |
124 | prepared for additional security frameworks. |
125 | ||
126 | * udev gained a new scheme to configure link-level attributes | |
127 | from files in /etc/systemd/network/*.link. These files can | |
8b7d0494 | 128 | match against MAC address, device path, driver name and type, |
4c2413bf | 129 | and will apply attributes like the naming policy, link speed, |
8b7d0494 | 130 | MTU, duplex settings, Wake-on-LAN settings, MAC address, MAC |
e49b5aad LP |
131 | address assignment policy (randomized, ...). |
132 | ||
dfb08b05 ZJS |
133 | * The configuration of network interface naming rules for |
134 | "permanent interface names" has changed: a new NamePolicy= | |
135 | setting in the [Link] section of .link files determines the | |
136 | priority of possible naming schemes (onboard, slot, mac, | |
137 | path). The default value of this setting is determined by | |
138 | /usr/lib/net/links/99-default.link. Old | |
139 | 80-net-name-slot.rules udev configuration file has been | |
140 | removed, so local configuration overriding this file should | |
141 | be adapated to override 99-default.link instead. | |
142 | ||
e49b5aad | 143 | * When the User= switch is used in a unit file, also |
4c2413bf | 144 | initialize $SHELL= based on the user database entry. |
e49b5aad LP |
145 | |
146 | * systemd no longer depends on libdbus. All communication is | |
147 | now done with sd-bus, systemd's low-level bus library | |
148 | implementation. | |
149 | ||
150 | * kdbus support has been added to PID 1 itself. When kdbus is | |
4c2413bf | 151 | enabled, this causes PID 1 to set up the system bus and |
e49b5aad LP |
152 | enable support for a new ".busname" unit type that |
153 | encapsulates bus name activation on kdbus. It works a little | |
154 | bit like ".socket" units, except for bus names. A new | |
155 | generator has been added that converts classic dbus1 service | |
156 | activation files automatically into native systemd .busname | |
157 | and .service units. | |
158 | ||
159 | * sd-bus: add a light-weight vtable implementation that allows | |
160 | defining objects on the bus with a simple static const | |
161 | vtable array of its methods, signals and properties. | |
162 | ||
8b7d0494 | 163 | * systemd will not generate or install static dbus |
e49b5aad | 164 | introspection data anymore to /usr/share/dbus-1/interfaces, |
1e190502 | 165 | as the precise format of these files is unclear, and |
e49b5aad LP |
166 | nothing makes use of it. |
167 | ||
168 | * A proxy daemon is now provided to proxy clients connecting | |
169 | via classic D-Bus AF_UNIX sockets to kdbus, to provide full | |
170 | compatibility with classic D-Bus. | |
171 | ||
172 | * A bus driver implementation has been added that supports the | |
173 | classic D-Bus bus driver calls on kdbus, also for | |
174 | compatibility purposes. | |
175 | ||
176 | * A new API "sd-event.h" has been added that implements a | |
177 | minimal event loop API built around epoll. It provides a | |
178 | couple of features that direct epoll usage is lacking: | |
b9761003 | 179 | prioritization of events, scales to large numbers of timer |
e49b5aad LP |
180 | events, per-event timer slack (accuracy), system-wide |
181 | coalescing of timer events, exit handlers, watchdog | |
182 | supervision support using systemd's sd_notify() API, child | |
183 | process handling. | |
184 | ||
185 | * A new API "sd-rntl.h" has been added that provides an API | |
186 | around the route netlink interface of the kernel, similar in | |
187 | style to "sd-bus.h". | |
188 | ||
7e95eda5 PF |
189 | * A new API "sd-dhcp-client.h" has been added that provides a |
190 | small DHCPv4 client-side implementation. This is used by | |
e49b5aad LP |
191 | "systemd-networkd". |
192 | ||
4c2413bf | 193 | * There is a new kernel command line option |
8b7d0494 JSJ |
194 | "systemd.restore_state=0|1". When set to "0", none of the |
195 | systemd tools will restore saved runtime state to hardware | |
196 | devices. More specifically, the rfkill and backlight states | |
197 | are not restored. | |
e49b5aad LP |
198 | |
199 | * The FsckPassNo= compatibility option in mount/service units | |
200 | has been removed. The fstab generator will now add the | |
201 | necessary dependencies automatically, and does not require | |
202 | PID1's support for that anymore. | |
203 | ||
8b7d0494 | 204 | * journalctl gained a new switch, --list-boots, that lists |
e49b5aad LP |
205 | recent boots with their times and boot IDs. |
206 | ||
207 | * The various tools like systemctl, loginctl, timedatectl, | |
208 | busctl, systemd-run, ... have gained a new switch "-M" to | |
209 | connect to a specific, local OS container (as direct | |
210 | connection, without requiring SSH). This works on any | |
211 | container that is registered with machined, such as those | |
212 | created by libvirt-lxc or nspawn. | |
213 | ||
214 | * systemd-run and systemd-analyze also gained support for "-H" | |
4c2413bf | 215 | to connect to remote hosts via SSH. This is particularly |
8b7d0494 JSJ |
216 | useful for systemd-run because it enables queuing of jobs |
217 | onto remote systems. | |
e49b5aad LP |
218 | |
219 | * machinectl gained a new command "login" to open a getty | |
220 | login in any local container. This works with any container | |
221 | that is registered with machined (such as those created by | |
8e420494 | 222 | libvirt-lxc or nspawn), and which runs systemd inside. |
e49b5aad LP |
223 | |
224 | * machinectl gained a new "reboot" command that may be used to | |
225 | trigger a reboot on a specific container that is registered | |
226 | with machined. This works on any container that runs an init | |
227 | system of some kind. | |
228 | ||
229 | * systemctl gained a new "list-timers" command to print a nice | |
230 | listing of installed timer units with the times they elapse | |
231 | next. | |
232 | ||
233 | * Alternative reboot() parameters may now be specified on the | |
234 | "systemctl reboot" command line and are passed to the | |
235 | reboot() system call. | |
236 | ||
237 | * systemctl gained a new --job-mode= switch to configure the | |
238 | mode to queue a job with. This is a more generic version of | |
8b7d0494 | 239 | --fail, --irreversible, and --ignore-dependencies, which are |
e49b5aad LP |
240 | still available but not advertised anymore. |
241 | ||
e49b5aad LP |
242 | * /etc/systemd/system.conf gained new settings to configure |
243 | various default timeouts of units, as well as the default | |
b9761003 | 244 | start limit interval and burst. These may still be overridden |
e49b5aad LP |
245 | within each Unit. |
246 | ||
270f1624 LP |
247 | * PID1 will now export on the bus profile data of the security |
248 | policy upload process (such as the SELinux policy upload to | |
8e420494 | 249 | the kernel). |
e49b5aad | 250 | |
4670e9d5 | 251 | * journald: when forwarding logs to the console, include |
1e190502 ZJS |
252 | timestamps (following the setting in |
253 | /sys/module/printk/parameters/time). | |
e49b5aad LP |
254 | |
255 | * OnCalendar= in timer units now understands the special | |
256 | strings "yearly" and "annually". (Both are equivalent) | |
257 | ||
258 | * The accuracy of timer units is now configurable with the new | |
259 | AccuracySec= setting. It defaults to 1min. | |
260 | ||
261 | * A new dependency type JoinsNamespaceOf= has been added that | |
262 | allows running two services within the same /tmp and network | |
263 | namespace, if PrivateNetwork= or PrivateTmp= are used. | |
264 | ||
265 | * A new command "cat" has been added to systemctl. It outputs | |
266 | the original unit file of a unit, and concatenates the | |
1e190502 ZJS |
267 | contents of additional "drop-in" unit file snippets, so that |
268 | the full configuration is shown. | |
e49b5aad LP |
269 | |
270 | * systemctl now supports globbing on the various "list-xyz" | |
271 | commands, like "list-units" or "list-sockets", as well as on | |
1e190502 ZJS |
272 | those commands which take multiple unit names. |
273 | ||
274 | * journalctl's --unit= switch gained support for globbing. | |
e49b5aad LP |
275 | |
276 | * All systemd daemons now make use of the watchdog logic so | |
277 | that systemd automatically notices when they hang. | |
278 | ||
4c2413bf | 279 | * If the $container_ttys environment variable is set, |
e49b5aad LP |
280 | getty-generator will automatically spawn a getty for each |
281 | listed tty. This is useful for container managers to request | |
282 | login gettys to be spawned on as many ttys as needed. | |
283 | ||
284 | * %h, %s, %U specifier support is not available anymore when | |
285 | used in unit files for PID 1. This is because NSS calls are | |
286 | not safe from PID 1. They stay available for --user | |
287 | instances of systemd, and as special case for the root user. | |
288 | ||
e49b5aad LP |
289 | * loginctl gained a new "--no-legend" switch to turn off output |
290 | of the legend text. | |
291 | ||
292 | * The "sd-login.h" API gained three new calls: | |
293 | sd_session_is_remote(), sd_session_get_remote_user(), | |
294 | sd_session_get_remote_host() to query information about | |
295 | remote sessions. | |
296 | ||
8e420494 LP |
297 | * The udev hardware database now also carries vendor/product |
298 | information of SDIO devices. | |
e49b5aad LP |
299 | |
300 | * The "sd-daemon.h" API gained a new sd_watchdog_enabled() to | |
301 | determine whether watchdog notifications are requested by | |
302 | the system manager. | |
303 | ||
1e190502 | 304 | * Socket-activated per-connection services now include a |
e49b5aad LP |
305 | short description of the connection parameters in the |
306 | description. | |
307 | ||
4c2413bf | 308 | * tmpfiles gained a new "--boot" option. When this is not used, |
e49b5aad | 309 | only lines where the command character is not suffixed with |
4670e9d5 | 310 | "!" are executed. When this option is specified, those |
1e190502 ZJS |
311 | options are executed too. This partitions tmpfiles |
312 | directives into those that can be safely executed at any | |
313 | time, and those which should be run only at boot (for | |
314 | example, a line that creates /run/nologin). | |
e49b5aad | 315 | |
c0c5af00 | 316 | * A new API "sd-resolve.h" has been added which provides a simple |
4c2413bf | 317 | asynchronous wrapper around glibc NSS host name resolution |
e49b5aad | 318 | calls, such as getaddrinfo(). In contrast to glibc's |
4c2413bf JE |
319 | getaddrinfo_a(), it does not use signals. In contrast to most |
320 | other asynchronous name resolution libraries, this one does | |
321 | not reimplement DNS, but reuses NSS, so that alternate | |
e49b5aad | 322 | host name resolution systems continue to work, such as mDNS, |
8b7d0494 | 323 | LDAP, etc. This API is based on libasyncns, but it has been |
e49b5aad LP |
324 | cleaned up for inclusion in systemd. |
325 | ||
6300b3ec LP |
326 | * The APIs "sd-journal.h", "sd-login.h", "sd-id128.h", |
327 | "sd-daemon.h" are no longer found in individual libraries | |
328 | libsystemd-journal.so, libsystemd-login.so, | |
329 | libsystemd-id128.so, libsystemd-daemon.so. Instead, we have | |
8b7d0494 JSJ |
330 | merged them into a single library, libsystemd.so, which |
331 | provides all symbols. The reason for this is cyclic | |
e49b5aad | 332 | dependencies, as these libraries tend to use each other's |
6300b3ec LP |
333 | symbols. So far, we've managed to workaround that by linking |
334 | a copy of a good part of our code into each of these | |
335 | libraries again and again, which, however, makes certain | |
336 | things hard to do, like sharing static variables. Also, it | |
337 | substantially increases footprint. With this change, there | |
338 | is only one library for the basic APIs systemd | |
339 | provides. Also, "sd-bus.h", "sd-memfd.h", "sd-event.h", | |
340 | "sd-rtnl.h", "sd-resolve.h", "sd-utf8.h" are found in this | |
341 | library as well, however are subject to the --enable-kdbus | |
342 | switch (see below). Note that "sd-dhcp-client.h" is not part | |
343 | of this library (this is because it only consumes, never | |
344 | provides, services of/to other APIs). To make the transition | |
8b7d0494 | 345 | easy from the separate libraries to the unified one, we |
4c2413bf | 346 | provide the --enable-compat-libs compile-time switch which |
e49b5aad LP |
347 | will generate stub libraries that are compatible with the |
348 | old ones but redirect all calls to the new one. | |
349 | ||
8b7d0494 | 350 | * All of the kdbus logic and the new APIs "sd-bus.h", |
e49b5aad | 351 | "sd-memfd.h", "sd-event.h", "sd-rtnl.h", "sd-resolve.h", |
8b7d0494 JSJ |
352 | and "sd-utf8.h" are compile-time optional via the |
353 | "--enable-kdbus" switch, and they are not compiled in by | |
354 | default. To make use of kdbus, you have to explicitly enable | |
4c2413bf | 355 | the switch. Note however, that neither the kernel nor the |
e49b5aad LP |
356 | userspace API for all of this is considered stable yet. We |
357 | want to maintain the freedom to still change the APIs for | |
4c2413bf | 358 | now. By specifying this build-time switch, you acknowledge |
e49b5aad | 359 | that you are aware of the instability of the current |
ad42cf73 KS |
360 | APIs. |
361 | ||
362 | * Also, note that while kdbus is pretty much complete, | |
e49b5aad | 363 | it lacks one thing: proper policy support. This means you |
8b7d0494 | 364 | can build a fully working system with all features; however, |
4c2413bf JE |
365 | it will be highly insecure. Policy support will be added in |
366 | one of the next releases, at the same time that we will | |
367 | declare the APIs stable. | |
e49b5aad | 368 | |
8b7d0494 | 369 | * When the kernel command-line argument "kdbus" is specified, |
ad42cf73 | 370 | systemd will automatically load the kdbus.ko kernel module. At |
8b7d0494 | 371 | this stage of development, it is only useful for testing kdbus |
ad42cf73 | 372 | and should not be used in production. Note: if "--enable-kdbus" |
8b7d0494 | 373 | is specified, and the kdbus.ko kernel module is available, and |
ad42cf73 KS |
374 | "kdbus" is added to the kernel command line, the entire system |
375 | runs with kdbus instead of dbus-daemon, with the above mentioned | |
376 | problem of missing the system policy enforcement. Also a future | |
377 | version of kdbus.ko or a newer systemd will not be compatible with | |
378 | each other, and will unlikely be able to boot the machine if only | |
379 | one of them is updated. | |
380 | ||
e49b5aad | 381 | * systemctl gained a new "import-environment" command which |
4c2413bf | 382 | uploads the caller's environment (or parts thereof) into the |
e49b5aad LP |
383 | service manager so that it is inherited by services started |
384 | by the manager. This is useful to upload variables like | |
385 | $DISPLAY into the user service manager. | |
386 | ||
387 | * A new PrivateDevices= switch has been added to service units | |
388 | which allows running a service with a namespaced /dev | |
389 | directory that does not contain any device nodes for | |
4c2413bf | 390 | physical devices. More specifically, it only includes devices |
8b7d0494 | 391 | such as /dev/null, /dev/urandom, and /dev/zero which are API |
e49b5aad LP |
392 | entry points. |
393 | ||
394 | * logind has been extended to support behaviour like VT | |
395 | switching on seats that do not support a VT. This makes | |
396 | multi-session available on seats that are not the first seat | |
397 | (seat0), and on systems where kernel support for VTs has | |
8b7d0494 | 398 | been disabled at compile-time. |
e49b5aad LP |
399 | |
400 | * If a process holds a delay lock for system sleep or shutdown | |
1e190502 | 401 | and fails to release it in time, we will now log its |
e49b5aad LP |
402 | identity. This makes it easier to identify processes that |
403 | cause slow suspends or power-offs. | |
404 | ||
1e190502 ZJS |
405 | * When parsing /etc/crypttab, support for a new key-slot= |
406 | option as supported by Debian is added. It allows indicating | |
407 | which LUKS slot to use on disk, speeding up key loading. | |
e49b5aad | 408 | |
1e190502 ZJS |
409 | * The sd_journald_sendv() API call has been checked and |
410 | officially declared to be async-signal-safe so that it may | |
411 | be invoked from signal handlers for logging purposes. | |
e49b5aad LP |
412 | |
413 | * Boot-time status output is now enabled automatically after a | |
414 | short timeout if boot does not progress, in order to give | |
8e420494 | 415 | the user an indication what she or he is waiting for. |
1e190502 ZJS |
416 | |
417 | * The boot-time output has been improved to show how much time | |
418 | remains until jobs expire. | |
e49b5aad LP |
419 | |
420 | * The KillMode= switch in service units gained a new possible | |
8b7d0494 | 421 | value "mixed". If set, and the unit is shut down, then the |
e49b5aad | 422 | initial SIGTERM signal is sent only to the main daemon |
8e420494 | 423 | process, while the following SIGKILL signal is sent to |
e49b5aad LP |
424 | all remaining processes of the service. |
425 | ||
4c2413bf JE |
426 | * When a scope unit is registered, a new property "Controller" |
427 | may be set. If set to a valid bus name, systemd will send a | |
e49b5aad LP |
428 | RequestStop() signal to this name when it would like to shut |
429 | down the scope. This may be used to hook manager logic into | |
430 | the shutdown logic of scope units. Also, scope units may now | |
8b7d0494 | 431 | be put in a special "abandoned" state, in which case the |
e49b5aad LP |
432 | manager process which created them takes no further |
433 | responsibilities for it. | |
434 | ||
1e190502 | 435 | * When reading unit files, systemd will now verify |
e49b5aad LP |
436 | the access mode of these files, and warn about certain |
437 | suspicious combinations. This has been added to make it | |
438 | easier to track down packaging bugs where unit files are | |
439 | marked executable or world-writable. | |
440 | ||
441 | * systemd-nspawn gained a new "--setenv=" switch to set | |
8b7d0494 | 442 | container-wide environment variables. The similar option in |
1e190502 ZJS |
443 | systemd-activate was renamed from "--environment=" to |
444 | "--setenv=" for consistency. | |
e49b5aad LP |
445 | |
446 | * systemd-nspawn has been updated to create a new kdbus domain | |
447 | for each container that is invoked, thus allowing each | |
b9761003 | 448 | container to have its own set of system and user buses, |
8b7d0494 | 449 | independent of the host. |
e49b5aad LP |
450 | |
451 | * systemd-nspawn gained a new --drop-capability= switch to run | |
452 | the container with less capabilities than the default. Both | |
b9761003 | 453 | --drop-capability= and --capability= now take the special |
e49b5aad LP |
454 | string "all" for dropping or keeping all capabilities. |
455 | ||
456 | * systemd-nspawn gained new switches for executing containers | |
457 | with specific SELinux labels set. | |
458 | ||
459 | * systemd-nspawn gained a new --quiet switch to not generate | |
460 | any additional output but the container's own console | |
461 | output. | |
462 | ||
463 | * systemd-nspawn gained a new --share-system switch to run a | |
464 | container without PID namespacing enabled. | |
465 | ||
466 | * systemd-nspawn gained a new --register= switch to control | |
1e190502 | 467 | whether the container is registered with systemd-machined or |
8e420494 | 468 | not. This is useful for containers that do not run full |
e49b5aad LP |
469 | OS images, but only specific apps. |
470 | ||
471 | * systemd-nspawn gained a new --keep-unit which may be used | |
8b7d0494 | 472 | when invoked as the only program from a service unit, and |
e49b5aad | 473 | results in registration of the unit service itself in |
1e190502 | 474 | systemd-machined, instead of a newly opened scope unit. |
e49b5aad LP |
475 | |
476 | * systemd-nspawn gained a new --network-interface= switch for | |
477 | moving arbitrary interfaces to the container. The new | |
4c2413bf | 478 | --network-veth switch creates a virtual Ethernet connection |
8b7d0494 JSJ |
479 | between host and container. The new --network-bridge= |
480 | switch then allows assigning the host side of this virtual | |
481 | Ethernet connection to a bridge device. | |
e49b5aad | 482 | |
6afc95b7 LP |
483 | * systemd-nspawn gained a new --personality= switch for |
484 | setting the kernel personality for the container. This is | |
ca721e36 LP |
485 | useful when running a 32bit container on a 64bit host. A |
486 | similar option Personality= is now also available in service | |
487 | units. | |
6afc95b7 | 488 | |
e49b5aad LP |
489 | * logind will now also track a "Desktop" identifier for each |
490 | session which encodes the desktop environment of it. This is | |
491 | useful for desktop environments that want to identify | |
492 | multiple running sessions of itself easily. | |
493 | ||
494 | * A new SELinuxContext= setting for service units has been | |
495 | added that allows setting a specific SELinux execution | |
496 | context for a service. | |
497 | ||
498 | * Most systemd client tools will now honour $SYSTEMD_LESS for | |
499 | settings of the "less" pager. By default, these tools will | |
8b7d0494 JSJ |
500 | override $LESS to allow certain operations to work, such as |
501 | jump-to-the-end. With $SYSTEMD_LESS, it is possible to | |
e49b5aad LP |
502 | influence this logic. |
503 | ||
504 | * systemd's "seccomp" hook-up has been changed to make use of | |
505 | the libseccomp library instead of using its own | |
506 | implementation. This has benefits for portability among | |
507 | other things. | |
508 | ||
4c2413bf | 509 | * For usage together with SystemCallFilter=, a new |
8b7d0494 | 510 | SystemCallErrorNumber= setting has been introduced that |
8e420494 | 511 | allows configuration of a system error number to return on |
8b7d0494 | 512 | filtered system calls, instead of immediately killing the |
e49b5aad LP |
513 | process. Also, SystemCallArchitectures= has been added to |
514 | limit access to system calls of a particular architecture | |
515 | (in order to turn off support for unused secondary | |
4c2413bf | 516 | architectures). There is also a global |
8b7d0494 | 517 | SystemCallArchitectures= setting in system.conf now to turn |
e49b5aad LP |
518 | off support for non-native system calls system-wide. |
519 | ||
210054d7 KS |
520 | * systemd requires a kernel with a working name_to_handle_at(), |
521 | please see the kernel config requirements in the README file. | |

cd4010b3 LP |
550 | CHANGES WITH 208: |
551 | ||
552 | * logind has gained support for facilitating privileged input | |
553 | and drm device access for unprivileged clients. This work is | |
554 | useful to allow Wayland display servers (and similar | |
555 | programs, such as kmscon) to run under the user's ID and | |
556 | access input and drm devices which are normally | |
557 | protected. When this is used (and the kernel is new enough) | |
558 | logind will "mute" IO on the file descriptors passed to | |
559 | Wayland as long as it is in the background and "unmute" it | |
560 | if it returns into the foreground. This allows secure | |
561 | session switching without allowing background sessions to | |
562 | eavesdrop on input and display data. This also introduces | |
563 | session switching support if VT support is turned off in the | |
564 | kernel, and on seats that are not seat0. | |
565 | ||
566 | * A new kernel command line option luks.options= is understood | |
567 | now which allows specifiying LUKS options for usage for LUKS | |
568 | encrypted partitions specified with luks.uuid=. | |
569 | ||
570 | * tmpfiles.d(5) snippets may now use specifier expansion in | |
571 | path names. More specifically %m, %b, %H, %v, are now | |
572 | replaced by the local machine id, boot id, hostname, and | |
573 | kernel version number. | |
574 | ||
575 | * A new tmpfiles.d(5) command "m" has been introduced which | |
576 | may be used to change the owner/group/access mode of a file | |
577 | or directory if it exists, but do nothing if it doesn't. | |
578 | ||
579 | * This release removes high-level support for the | |
580 | MemorySoftLimit= cgroup setting. The underlying kernel | |
581 | cgroup attribute memory.soft_limit= is currently badly | |
582 | designed and likely to be removed from the kernel API in its | |
583 | current form, hence we shouldn't expose it for now. | |
584 | ||
585 | * The memory.use_hierarchy cgroup attribute is now enabled for | |
586 | all cgroups systemd creates in the memory cgroup | |
587 | hierarchy. This option is likely to be come the built-in | |
588 | default in the kernel anyway, and the non-hierarchial mode | |
589 | never made much sense in the intrinsically hierarchial | |
590 | cgroup system. | |
591 | ||
592 | * A new field _SYSTEMD_SLICE= is logged along with all journal | |
593 | messages containing the slice a message was generated | |
594 | from. This is useful to allow easy per-customer filtering of | |
595 | logs among other things. | |
596 | ||
597 | * systemd-journald will no longer adjust the group of journal | |
598 | files it creates to the "systemd-journal" group. Instead we | |
599 | rely on the journal directory to be owned by the | |
600 | "systemd-journal" group, and its setgid bit set, so that the | |
601 | kernel file system layer will automatically enforce that | |
602 | journal files inherit this group assignment. The reason for | |
603 | this change is that we cannot allow NSS look-ups from | |
604 | journald which would be necessary to resolve | |
605 | "systemd-journal" to a numeric GID, because this might | |
606 | create deadlocks if NSS involves synchronous queries to | |
607 | other daemons (such as nscd, or sssd) which in turn are | |
608 | logging clients of journald and might block on it, which | |
609 | would then dead lock. A tmpfiles.d(5) snippet included in | |
610 | systemd will make sure the setgid bit and group are | |
611 | properly set on the journal directory if it exists on every | |
612 | boot. However, we recommend adjusting it manually after | |
613 | upgrades too (or from RPM scriptlets), so that the change is | |
614 | not delayed until next reboot. | |
615 | ||
616 | * Backlight and random seed files in /var/lib/ have moved into | |
617 | the /var/lib/systemd/ directory, in order to centralize all | |
618 | systemd generated files in one directory. | |
619 | ||
620 | * Boot time performance measurements (as displayed by | |
621 | "systemd-analyze" for example) will now read ACPI 5.0 FPDT | |
622 | performance information if that's available to determine how | |
623 | much time BIOS and boot loader initialization required. With | |
624 | a sufficiently new BIOS you hence no longer need to boot | |
625 | with Gummiboot to get access to such information. | |

4f0be680 LP |
637 | CHANGES WITH 207: |
638 | ||
639 | * The Restart= option for services now understands a new | |
f3a165b0 | 640 | on-watchdog setting, which will restart the service |
4f0be680 LP |
641 | automatically if the service stops sending out watchdog keep |
642 | alive messages (as configured with WatchdogSec=). | |
643 | ||
644 | * The getty generator (which is responsible for bringing up a | |
645 | getty on configured serial consoles) will no longer only | |
646 | start a getty on the primary kernel console but on all | |
647 | others, too. This makes the order in which console= is | |
648 | specified on the kernel command line less important. | |
649 | ||
650 | * libsystemd-logind gained a new sd_session_get_vt() call to | |
651 | retrieve the VT number of a session. | |
652 | ||
653 | * If the option "tries=0" is set for an entry of /etc/crypttab | |
654 | its passphrase is queried indefinitely instead of any | |
655 | maximum number of tries. | |
656 | ||
657 | * If a service with a configure PID file terminates its PID | |
658 | file will now be removed automatically if it still exists | |
659 | afterwards. This should put an end to stale PID files. | |
660 | ||
661 | * systemd-run will now also take relative binary path names | |
662 | for execution and no longer insists on absolute paths. | |
663 | ||
664 | * InaccessibleDirectories= and ReadOnlyDirectories= now take | |
665 | paths that are optionally prefixed with "-" to indicate that | |
666 | it should not be considered a failure if they don't exist. | |
667 | ||
f3a165b0 KS |
668 | * journalctl -o (and similar commands) now understands a new |
669 | output mode "short-precise", it is similar to "short" but | |
4f0be680 LP |
670 | shows timestamps with usec accuracy. |
671 | ||
672 | * The option "discard" (as known from Debian) is now | |
673 | synonymous to "allow-discards" in /etc/crypttab. In fact, | |
387abf80 | 674 | "discard" is preferred now (since it is easier to remember |
4f0be680 LP |
675 | and type). |
676 | ||
f3a165b0 | 677 | * Some licensing clean-ups were made, so that more code is now |
4f0be680 LP |
678 | LGPL-2.1 licensed than before. |
679 | ||
680 | * A minimal tool to save/restore the display backlight | |
681 | brightness across reboots has been added. It will store the | |
f3a165b0 | 682 | backlight setting as late as possible at shutdown, and |
4f0be680 LP |
683 | restore it as early as possible during reboot. |
684 | ||
685 | * A logic to automatically discover and enable home and swap | |
686 | partitions on GPT disks has been added. With this in place | |
687 | /etc/fstab becomes optional for many setups as systemd can | |
688 | discover certain partitions located on the root disk | |
689 | automatically. Home partitions are recognized under their | |
690 | GPT type ID 933ac7e12eb44f13b8440e14e2aef915. Swap | |
691 | partitions are recognized under their GPT type ID | |
692 | 0657fd6da4ab43c484e50933c84b4f4f. | |
693 | ||
694 | * systemd will no longer pass any environment from the kernel | |
695 | or initrd to system services. If you want to set an | |
696 | environment for all services, do so via the kernel command | |
697 | line systemd.setenv= assignment. | |
698 | ||
387abf80 LP |
699 | * The systemd-sysctl tool no longer natively reads the file |
700 | /etc/sysctl.conf. If desired, the file should be symlinked | |
701 | from /etc/sysctl.d/99-sysctl.conf. Apart from providing | |
702 | legacy support by a symlink rather than built-in code, it | |
703 | also makes the otherwise hidden order of application of the | |
704 | different files visible. (Note that this partly reverts to a | |
705 | pre-198 application order of sysctl knobs!) | |
04bf3c1a | 706 | |
4f0be680 LP |
707 | * The "systemctl set-log-level" and "systemctl dump" commands |
708 | have been moved to systemd-analyze. | |
709 | ||
710 | * systemd-run learned the new --remain-after-exit switch, | |
711 | which causes the scope unit not to be cleaned up | |
712 | automatically after the process terminated. | |
713 | ||
714 | * tmpfiles learned a new --exclude-prefix= switch to exclude | |
715 | certain paths from operation. | |
716 | ||
717 | * journald will now automatically flush all messages to disk | |
718 | as soon as a message of the log priorities CRIT, ALERT or | |
719 | EMERG is received. | |

408f281b LP |
737 | CHANGES WITH 206: |
738 | ||
739 | * The documentation has been updated to cover the various new | |
740 | concepts introduced with 205. | |
741 | ||
742 | * Unit files now understand the new %v specifier which | |
743 | resolves to the kernel version string as returned by "uname | |
744 | -r". | |
745 | ||
746 | * systemctl now supports filtering the unit list output by | |
747 | load state, active state and sub state, using the new | |
33b521be | 748 | --state= parameter. |
408f281b LP |
749 | |
750 | * "systemctl status" will now show the results of the | |
751 | condition checks (like ConditionPathExists= and similar) of | |
752 | the last start attempts of the unit. They are also logged to | |
753 | the journal. | |
754 | ||
755 | * "journalctl -b" may now be used to look for boot output of a | |
756 | specific boot. Try "journalctl -b -1" for the previous boot, | |
757 | but the syntax is substantially more powerful. | |
758 | ||
759 | * "journalctl --show-cursor" has been added which prints the | |
760 | cursor string the last shown log line. This may then be used | |
761 | with the new "journalctl --after-cursor=" switch to continue | |
762 | browsing logs from that point on. | |
763 | ||
764 | * "journalctl --force" may now be used to force regeneration | |
765 | of an FSS key. | |
766 | ||
251cc819 LP |
767 | * Creation of "dead" device nodes has been moved from udev |
768 | into kmod and tmpfiles. Previously, udev would read the kmod | |
769 | databases to pre-generate dead device nodes based on meta | |
770 | information contained in kernel modules, so that these would | |
771 | be auto-loaded on access rather then at boot. As this | |
772 | doesn't really have much to do with the exposing actual | |
773 | kernel devices to userspace this has always been slightly | |
774 | alien in the udev codebase. Following the new scheme kmod | |
775 | will now generate a runtime snippet for tmpfiles from the | |
776 | module meta information and it now is tmpfiles' job to the | |
777 | create the nodes. This also allows overriding access and | |
778 | other parameters for the nodes using the usual tmpfiles | |
779 | facilities. As side effect this allows us to remove the | |
780 | CAP_SYS_MKNOD capability bit from udevd entirely. | |
781 | ||
782 | * logind's device ACLs may now be applied to these "dead" | |
783 | devices nodes too, thus finally allowing managed access to | |
784 | devices such as /dev/snd/sequencer whithout loading the | |
785 | backing module right-away. | |
408f281b LP |
786 | |
787 | * A new RPM macro has been added that may be used to apply | |
788 | tmpfiles configuration during package installation. | |
789 | ||
790 | * systemd-detect-virt and ConditionVirtualization= now can | |
791 | detect User-Mode-Linux machines (UML). | |
792 | ||
251cc819 LP |
793 | * journald will now implicitly log the effective capabilities |
794 | set of processes in the message metadata. | |
408f281b LP |
795 | |
796 | * systemd-cryptsetup has gained support for TrueCrypt volumes. | |
797 | ||
798 | * The initrd interface has been simplified (more specifically, | |
799 | support for passing performance data via environment | |
800 | variables and fsck results via files in /run has been | |
801 | removed). These features were non-essential, and are | |
802 | nowadays available in a much nicer way by having systemd in | |
803 | the initrd serialize its state and have the hosts systemd | |
804 | deserialize it again. | |
805 | ||
28f5c779 KS |
806 | * The udev "keymap" data files and tools to apply keyboard |
807 | specific mappings of scan to key codes, and force-release | |
808 | scan code lists have been entirely replaced by a udev | |
809 | "keyboard" builtin and a hwdb data file. | |
408f281b | 810 | |
251cc819 LP |
811 | * systemd will now honour the kernel's "quiet" command line |
812 | argument also during late shutdown, resulting in a | |
813 | completely silent shutdown when used. | |
814 | ||
815 | * There's now an option to control the SO_REUSEPORT socket | |
816 | option in .socket units. | |
817 | ||
818 | * Instance units will now automatically get a per-template | |
819 | subslice of system.slice unless something else is explicitly | |
820 | configured. For example, instances of sshd@.service will now | |
821 | implicitly be placed in system-sshd.slice rather than | |
822 | system.slice as before. | |
823 | ||
824 | * Test coverage support may now be enabled at build time. | |

00aa832b LP |
836 | CHANGES WITH 205: |
837 | ||
838 | * Two new unit types have been introduced: | |
839 | ||
840 | Scope units are very similar to service units, however, are | |
841 | created out of pre-existing processes -- instead of PID 1 | |
842 | forking off the processes. By using scope units it is | |
843 | possible for system services and applications to group their | |
844 | own child processes (worker processes) in a powerful way | |
845 | which then maybe used to organize them, or kill them | |
846 | together, or apply resource limits on them. | |
847 | ||
848 | Slice units may be used to partition system resources in an | |
849 | hierarchial fashion and then assign other units to them. By | |
850 | default there are now three slices: system.slice (for all | |
851 | system services), user.slice (for all user sessions), | |
852 | machine.slice (for VMs and containers). | |
853 | ||
854 | Slices and scopes have been introduced primarily in | |
855 | context of the work to move cgroup handling to a | |
856 | single-writer scheme, where only PID 1 | |
857 | creates/removes/manages cgroups. | |
858 | ||
859 | * There's a new concept of "transient" units. In contrast to | |
860 | normal units these units are created via an API at runtime, | |
861 | not from configuration from disk. More specifically this | |
862 | means it is now possible to run arbitrary programs as | |
863 | independent services, with all execution parameters passed | |
864 | in via bus APIs rather than read from disk. Transient units | |
865 | make systemd substantially more dynamic then it ever was, | |
866 | and useful as a general batch manager. | |
867 | ||
868 | * logind has been updated to make use of scope and slice units | |
869 | for managing user sessions. As a user logs in he will get | |
870 | his own private slice unit, to which all sessions are added | |
871 | as scope units. We also added support for automatically | |
872 | adding an instance of user@.service for the user into the | |
873 | slice. Effectively logind will no longer create cgroup | |
874 | hierarchies on its own now, it will defer entirely to PID 1 | |
875 | for this by means of scope, service and slice units. Since | |
876 | user sessions this way become entities managed by PID 1 | |
877 | the output of "systemctl" is now a lot more comprehensive. | |
878 | ||
879 | * A new mini-daemon "systemd-machined" has been added which | |
880 | may be used by virtualization managers to register local | |
881 | VMs/containers. nspawn has been updated accordingly, and | |
882 | libvirt will be updated shortly. machined will collect a bit | |
883 | of meta information about the VMs/containers, and assign | |
884 | them their own scope unit (see above). The collected | |
885 | meta-data is then made available via the "machinectl" tool, | |
886 | and exposed in "ps" and similar tools. machined/machinectl | |
887 | is compile-time optional. | |
888 | ||
889 | * As discussed earlier, the low-level cgroup configuration | |
890 | options ControlGroup=, ControlGroupModify=, | |
891 | ControlGroupPersistent=, ControlGroupAttribute= have been | |
892 | removed. Please use high-level attribute settings instead as | |
893 | well as slice units. | |
894 | ||
895 | * A new bus call SetUnitProperties() has been added to alter | |
896 | various runtime parameters of a unit. This is primarily | |
897 | useful to alter cgroup parameters dynamically in a nice way, | |
898 | but will be extended later on to make more properties | |
899 | modifiable at runtime. systemctl gained a new set-properties | |
900 | command that wraps this call. | |
901 | ||
902 | * A new tool "systemd-run" has been added which can be used to | |
903 | run arbitrary command lines as transient services or scopes, | |
904 | while configuring a number of settings via the command | |
905 | line. This tool is currently very basic, however already | |
906 | very useful. We plan to extend this tool to even allow | |
907 | queuing of execution jobs with time triggers from the | |
908 | command line, similar in fashion to "at". | |
909 | ||
910 | * nspawn will now inform the user explicitly that kernels with | |
911 | audit enabled break containers, and suggest the user to turn | |
912 | off audit. | |
913 | ||
914 | * Support for detecting the IMA and AppArmor security | |
915 | frameworks with ConditionSecurity= has been added. | |
916 | ||
917 | * journalctl gained a new "-k" switch for showing only kernel | |
1fda0ab5 ZJS |
918 | messages, mimicking dmesg output; in addition to "--user" |
919 | and "--system" switches for showing only user's own logs | |
920 | and system logs. | |
00aa832b LP |
921 | |
922 | * systemd-delta can now show information about drop-in | |
923 | snippets extending unit files. | |
924 | ||
925 | * libsystemd-bus has been substantially updated but is still | |
926 | not available as public API. | |
927 | ||
928 | * systemd will now look for the "debug" argument on the kernel | |
929 | command line and enable debug logging, similar to | |
930 | "systemd.log_level=debug" already did before. | |
931 | ||
932 | * "systemctl set-default", "systemctl get-default" has been | |
933 | added to configure the default.target symlink, which | |
934 | controls what to boot into by default. | |
935 | ||
1fda0ab5 ZJS |
936 | * "systemctl set-log-level" has been added as a convenient |
937 | way to raise and lower systemd logging threshold. | |
938 | ||
00aa832b LP |
939 | * "systemd-analyze plot" will now show the time the various |
940 | generators needed for execution, as well as information | |
941 | about the unit file loading. | |
942 | ||
00aa832b LP |
943 | * libsystemd-journal gained a new sd_journal_open_files() call |
944 | for opening specific journal files. journactl also gained a | |
945 | new switch to expose this new functionality. Previously we | |
946 | only supported opening all files from a directory, or all | |
947 | files from the system, as opening individual files only is | |
948 | racy due to journal file rotation. | |
949 | ||
950 | * systemd gained the new DefaultEnvironment= setting in | |
951 | /etc/systemd/system.conf to set environment variables for | |
952 | all services. | |
953 | ||
954 | * If a privileged process logs a journal message with the | |
955 | OBJECT_PID= field set, then journald will automatically | |
956 | augment this with additional OBJECT_UID=, OBJECT_GID=, | |
957 | OBJECT_COMM=, OBJECT_EXE=, ... fields. This is useful if | |
958 | system services want to log events about specific client | |
959 | processes. journactl/systemctl has been updated to make use | |
960 | of this information if all log messages regarding a specific | |
961 | unit is requested. | |

977 | CHANGES WITH 204: |
978 | ||
979 | * The Python bindings gained some minimal support for the APIs | |
980 | exposed by libsystemd-logind. | |
981 | ||
982 | * ConditionSecurity= gained support for detecting SMACK. Since | |
983 | this condition already supports SELinux and AppArmor we only | |
984 | miss IMA for this. Patches welcome! | |

2f3fcf85 LP |
989 | CHANGES WITH 203: |
990 | ||
991 | * systemd-nspawn will now create /etc/resolv.conf if | |
992 | necessary, before bind-mounting the host's file onto it. | |
993 | ||
994 | * systemd-nspawn will now store meta information about a | |
995 | container on the container's cgroup as extended attribute | |
996 | fields, including the root directory. | |
997 | ||
998 | * The cgroup hierarchy has been reworked in many ways. All | |
999 | objects any of the components systemd creates in the cgroup | |
b82eed9a | 1000 | tree are now suffixed. More specifically, user sessions are |
2f3fcf85 LP |
1001 | now placed in cgroups suffixed with ".session", users in |
1002 | cgroups suffixed with ".user", and nspawn containers in | |
1003 | cgroups suffixed with ".nspawn". Furthermore, all cgroup | |
1004 | names are now escaped in a simple scheme to avoid collision | |
1005 | of userspace object names with kernel filenames. This work | |
1006 | is preparation for making these objects relocatable in the | |
1007 | cgroup tree, in order to allow easy resource partitioning of | |
1008 | these objects without causing naming conflicts. | |
1009 | ||
1010 | * systemctl list-dependencies gained the new switches | |
1011 | --plain, --reverse, --after and --before. | |
1012 | ||
1013 | * systemd-inhibit now shows the process name of processes that | |
1014 | have taken an inhibitor lock. | |
1015 | ||
1016 | * nss-myhostname will now also resolve "localhost" | |
1017 | implicitly. This makes /etc/hosts an optional file and | |
1018 | nicely handles that on IPv6 ::1 maps to both "localhost" and | |
1019 | the local hostname. | |
1020 | ||
1021 | * libsystemd-logind.so gained a new call | |
1022 | sd_get_machine_names() to enumerate running containers and | |
1023 | VMs (currently only supported by very new libvirt and | |
1024 | nspawn). sd_login_monitor can now be used to watch | |
1025 | VMs/containers coming and going. | |
1026 | ||
1027 | * .include is not allowed recursively anymore, and only in | |
1028 | unit files. Usually it is better to use drop-in snippets in | |
1029 | .d/*.conf anyway, as introduced with systemd 198. | |
1030 | ||
1031 | * systemd-analyze gained a new "critical-chain" command that | |
1032 | determines the slowest chain of units run during system | |
1033 | boot-up. It is very useful for tracking down where | |
1034 | optimizing boot time is the most beneficial. | |
1035 | ||
1036 | * systemd will no longer allow manipulating service paths in | |
1037 | the name=systemd:/system cgroup tree using ControlGroup= in | |
1038 | units. (But is still fine with it in all other dirs.) | |
1039 | ||
1040 | * There's a new systemd-nspawn@.service service file that may | |
1041 | be used to easily run nspawn containers as system | |
1042 | services. With the container's root directory in | |
1043 | /var/lib/container/foobar it is now sufficient to run | |
1044 | "systemctl start systemd-nspawn@foobar.service" to boot it. | |
1045 | ||
1046 | * systemd-cgls gained a new parameter "--machine" to list only | |
1047 | the processes within a certain container. | |
1048 | ||
1049 | * ConditionSecurity= now can check for "apparmor". We still | |
1050 | are lacking checks for SMACK and IMA for this condition | |
1051 | check though. Patches welcome! | |
1052 | ||
1053 | * A new configuration file /etc/systemd/sleep.conf has been | |
1054 | added that may be used to configure which kernel operation | |
1055 | systemd is supposed to execute when "suspend", "hibernate" | |
1056 | or "hybrid-sleep" is requested. This makes the new kernel | |
1057 | "freeze" state accessible to the user. | |
1058 | ||
1059 | * ENV{SYSTEMD_WANTS} in udev rules will now implicitly escape | |
1060 | the passed argument if applicable. | |

ef3b5246 LP |
1071 | CHANGES WITH 202: |
1072 | ||
1073 | * The output of 'systemctl list-jobs' got some polishing. The | |
1074 | '--type=' argument may now be passed more than once. A new | |
1075 | command 'systemctl list-sockets' has been added which shows | |
1076 | a list of kernel sockets systemd is listening on with the | |
1077 | socket units they belong to, plus the units these socket | |
1078 | units activate. | |
1079 | ||
1080 | * The experimental libsystemd-bus library got substantial | |
1081 | updates to work in conjunction with the (also experimental) | |
1082 | kdbus kernel project. It works well enough to exchange | |
1083 | messages with some sophistication. Note that kdbus is not | |
1084 | ready yet, and the library is mostly an elaborate test case | |
1085 | for now, and not installable. | |
1086 | ||
1087 | * systemd gained a new unit 'systemd-static-nodes.service' | |
1088 | that generates static device nodes earlier during boot, and | |
1089 | can run in conjunction with udev. | |
1090 | ||
1091 | * libsystemd-login gained a new call sd_pid_get_user_unit() | |
1092 | to retrieve the user systemd unit a process is running | |
1093 | in. This is useful for systems where systemd is used as | |
1094 | session manager. | |
1095 | ||
1096 | * systemd-nspawn now places all containers in the new /machine | |
1097 | top-level cgroup directory in the name=systemd | |
1098 | hierarchy. libvirt will soon do the same, so that we get a | |
1099 | uniform separation of /system, /user and /machine for system | |
1100 | services, user processes and containers/virtual | |
1101 | machines. This new cgroup hierarchy is also useful to stick | |
1102 | stable names to specific container instances, which can be | |
7c04ad2d | 1103 | recognized later this way (this name may be controlled |
ef3b5246 LP |
1104 | via systemd-nspawn's new -M switch). libsystemd-login also |
1105 | gained a new call sd_pid_get_machine_name() to retrieve the | |
1106 | name of the container/VM a specific process belongs to. | |
1107 | ||
1108 | * bootchart can now store its data in the journal. | |
1109 | ||
1110 | * libsystemd-journal gained a new call | |
1111 | sd_journal_add_conjunction() for AND expressions to the | |
1112 | matching logic. This can be used to express more complex | |
1113 | logical expressions. | |
1114 | ||
1115 | * journactl can now take multiple --unit= and --user-unit= | |
1116 | switches. | |
1117 | ||
1118 | * The cryptsetup logic now understands the "luks.key=" kernel | |
1119 | command line switch for specifying a file to read the | |
7c04ad2d | 1120 | decryption key from. Also, if a configured key file is not |
ef3b5246 LP |
1121 | found the tool will now automatically fall back to prompting |
1122 | the user. | |
1123 | ||
cbeabcfb ZJS |
1124 | * Python systemd.journal module was updated to wrap recently |
1125 | added functions from libsystemd-journal. The interface was | |
1126 | changed to bring the low level interface in s.j._Reader | |
1127 | closer to the C API, and the high level interface in | |
1128 | s.j.Reader was updated to wrap and convert all data about | |
1129 | an entry. | |

d3a86981 LP |
1138 | CHANGES WITH 201: |
1139 | ||
1140 | * journalctl --update-catalog now understands a new --root= | |
1141 | option to operate on catalogs found in a different root | |
1142 | directory. | |
1143 | ||
1144 | * During shutdown after systemd has terminated all running | |
1145 | services a final killing loop kills all remaining left-over | |
1146 | processes. We will now print the name of these processes | |
1147 | when we send SIGKILL to them, since this usually indicates a | |
1148 | problem. | |
1149 | ||
1150 | * If /etc/crypttab refers to password files stored on | |
1151 | configured mount points automatic dependencies will now be | |
1152 | generated to ensure the specific mount is established first | |
1153 | before the key file is attempted to be read. | |
1154 | ||
1155 | * 'systemctl status' will now show information about the | |
1156 | network sockets a socket unit is listening on. | |
1157 | ||
1158 | * 'systemctl status' will also shown information about any | |
1159 | drop-in configuration file for units. (Drop-In configuration | |
1160 | files in this context are files such as | |
1161 | /etc/systemd/systemd/foobar.service.d/*.conf) | |
1162 | ||
1163 | * systemd-cgtop now optionally shows summed up CPU times of | |
1164 | cgroups. Press '%' while running cgtop to switch between | |
1165 | percentage and absolute mode. This is useful to determine | |
1166 | which cgroups use up the most CPU time over the entire | |
1167 | runtime of the system. systemd-cgtop has also been updated | |
1168 | to be 'pipeable' for processing with further shell tools. | |
1169 | ||
1170 | * 'hostnamectl set-hostname' will now allow setting of FQDN | |
1171 | hostnames. | |
1172 | ||
1173 | * The formatting and parsing of time span values has been | |
1174 | changed. The parser now understands fractional expressions | |
1175 | such as "5.5h". The formatter will now output fractional | |
1176 | expressions for all time spans under 1min, i.e. "5.123456s" | |
1177 | rather than "5s 123ms 456us". For time spans under 1s | |
1178 | millisecond values are shown, for those under 1ms | |
1179 | microsecond values are shown. This should greatly improve | |
1180 | all time-related output of systemd. | |
1181 | ||
1182 | * libsystemd-login and libsystemd-journal gained new | |
1183 | functions for querying the poll() events mask and poll() | |
1184 | timeout value for integration into arbitrary event | |
1185 | loops. | |
1186 | ||
1187 | * localectl gained the ability to list available X11 keymaps | |
1188 | (models, layouts, variants, options). | |
1189 | ||
1190 | * 'systemd-analyze dot' gained the ability to filter for | |
1191 | specific units via shell-style globs, to create smaller, | |
1192 | more useful graphs. I.e. it's now possible to create simple | |
1193 | graphs of all the dependencies between only target units, or | |
1194 | of all units that Avahi has dependencies with. | |

1204 | CHANGES WITH 200: |
1205 | ||
1206 | * The boot-time readahead implementation for rotating media | |
1207 | will now read the read-ahead data in multiple passes which | |
1208 | consist of all read requests made in equidistant time | |
1209 | intervals. This means instead of strictly reading read-ahead | |
1210 | data in its physical order on disk we now try to find a | |
1211 | middle ground between physical and access time order. | |
1212 | ||
1213 | * /etc/os-release files gained a new BUILD_ID= field for usage | |
1214 | on operating systems that provide continuous builds of OS | |
1215 | images. | |

1221 | CHANGES WITH 199: |
1222 | ||
1223 | * systemd-python gained an API exposing libsystemd-daemon. | |
1224 | ||
1225 | * The SMACK setup logic gained support for uploading CIPSO | |
1226 | security policy. | |
1227 | ||
1228 | * Behaviour of PrivateTmp=, ReadWriteDirectories=, | |
1229 | ReadOnlyDirectories= and InaccessibleDirectories= has | |
1230 | changed. The private /tmp and /var/tmp directories are now | |
1231 | shared by all processes of a service (which means | |
1232 | ExecStartPre= may now leave data in /tmp that ExecStart= of | |
1233 | the same service can still access). When a service is | |
1234 | stopped its temporary directories are immediately deleted | |
a87197f5 | 1235 | (normal clean-up with tmpfiles is still done in addition to |
35911459 LP |
1236 | this though). |
1237 | ||
1238 | * By default, systemd will now set a couple of sysctl | |
1239 | variables in the kernel: the safe sysrq options are turned | |
1240 | on, IP route verification is turned on, and source routing | |
1241 | disabled. The recently added hardlink and softlink | |
1242 | protection of the kernel is turned on. These settings should | |
1243 | be reasonably safe, and good defaults for all new systems. | |
1244 | ||
1245 | * The predictable network naming logic may now be turned off | |
a87197f5 | 1246 | with a new kernel command line switch: net.ifnames=0. |
35911459 LP |
1247 | |
1248 | * A new libsystemd-bus module has been added that implements a | |
1249 | pretty complete D-Bus client library. For details see: | |
1250 | ||
1251 | http://lists.freedesktop.org/archives/systemd-devel/2013-March/009797.html | |
1252 | ||
c20d8298 | 1253 | * journald will now explicitly flush the journal files to disk |
a87197f5 ZJS |
1254 | at the latest 5min after each write. The file will then also |
1255 | be marked offline until the next write. This should increase | |
1256 | reliability in case of a crash. The synchronization delay | |
1257 | can be configured via SyncIntervalSec= in journald.conf. | |
35911459 LP |
1258 | |
1259 | * There's a new remote-fs-setup.target unit that can be used | |
1260 | to pull in specific services when at least one remote file | |
1261 | system is to be mounted. | |
1262 | ||
1263 | * There are new targets timers.target and paths.target as | |
1264 | canonical targets to pull user timer and path units in | |
1265 | from. This complements sockets.target with a similar | |
1266 | purpose for socket units. | |
1267 | ||
6a7d3d68 LP |
1268 | * libudev gained a new call udev_device_set_attribute_value() |
1269 | to set sysfs attributes of a device. | |
1270 | ||
a87197f5 ZJS |
1271 | * The udev daemon now sets the default number of worker |
1272 | processes executed in parallel based on the number of available | |
c20d8298 | 1273 | CPUs instead of the amount of available RAM. This is supposed |
ab06eef8 | 1274 | to provide a more reliable default and limit a too aggressive |
c20d8298 KS |
1275 | paralellism for setups with 1000s of devices connected. |

85d68397 LP |
1287 | CHANGES WITH 198: |
1288 | ||
1289 | * Configuration of unit files may now be extended via drop-in | |
1290 | files without having to edit/override the unit files | |
1291 | themselves. More specifically, if the administrator wants to | |
1292 | change one value for a service file foobar.service he can | |
1293 | now do so by dropping in a configuration snippet into | |
ad88e758 | 1294 | /etc/systemd/system/foobar.service.d/*.conf. The unit logic |
85d68397 LP |
1295 | will load all these snippets and apply them on top of the |
1296 | main unit configuration file, possibly extending or | |
1297 | overriding its settings. Using these drop-in snippets is | |
40e21da8 KS |
1298 | generally nicer than the two earlier options for changing |
1299 | unit files locally: copying the files from | |
85d68397 LP |
1300 | /usr/lib/systemd/system/ to /etc/systemd/system/ and editing |
1301 | them there; or creating a new file in /etc/systemd/system/ | |
1302 | that incorporates the original one via ".include". Drop-in | |
1303 | snippets into these .d/ directories can be placed in any | |
fd868975 | 1304 | directory systemd looks for units in, and the usual |
85d68397 LP |
1305 | overriding semantics between /usr/lib, /etc and /run apply |
1306 | for them too. | |
1307 | ||
1308 | * Most unit file settings which take lists of items can now be | |
6aa8d43a | 1309 | reset by assigning the empty string to them. For example, |
85d68397 LP |
1310 | normally, settings such as Environment=FOO=BAR append a new |
1311 | environment variable assignment to the environment block, | |
1312 | each time they are used. By assigning Environment= the empty | |
1313 | string the environment block can be reset to empty. This is | |
1314 | particularly useful with the .d/*.conf drop-in snippets | |
156f7d09 KS |
1315 | mentioned above, since this adds the ability to reset list |
1316 | settings from vendor unit files via these drop-ins. | |
85d68397 LP |
1317 | |
1318 | * systemctl gained a new "list-dependencies" command for | |
1319 | listing the dependencies of a unit recursively. | |
1320 | ||
40e21da8 | 1321 | * Inhibitors are now honored and listed by "systemctl |
85d68397 LP |
1322 | suspend", "systemctl poweroff" (and similar) too, not only |
1323 | GNOME. These commands will also list active sessions by | |
1324 | other users. | |
1325 | ||
1326 | * Resource limits (as exposed by the various control group | |
1327 | controllers) can now be controlled dynamically at runtime | |
1328 | for all units. More specifically, you can now use a command | |
1329 | like "systemctl set-cgroup-attr foobar.service cpu.shares | |
1330 | 2000" to alter the CPU shares a specific service gets. These | |
6aa8d43a | 1331 | settings are stored persistently on disk, and thus allow the |
85d68397 LP |
1332 | administrator to easily adjust the resource usage of |
1333 | services with a few simple commands. This dynamic resource | |
6aa8d43a | 1334 | management logic is also available to other programs via the |
85d68397 LP |
1335 | bus. Almost any kernel cgroup attribute and controller is |
1336 | supported. | |
1337 | ||
1338 | * systemd-vconsole-setup will now copy all font settings to | |
6aa8d43a LP |
1339 | all allocated VTs, where it previously applied them only to |
1340 | the foreground VT. | |
85d68397 LP |
1341 | |
1342 | * libsystemd-login gained the new sd_session_get_tty() API | |
1343 | call. | |
1344 | ||
6aa8d43a LP |
1345 | * This release drops support for a few legacy or |
1346 | distribution-specific LSB facility names when parsing init | |
1347 | scripts: $x-display-manager, $mail-transfer-agent, | |
85d68397 LP |
1348 | $mail-transport-agent, $mail-transfer-agent, $smtp, |
1349 | $null. Also, the mail-transfer-agent.target unit backing | |
1350 | this has been removed. Distributions which want to retain | |
6aa8d43a LP |
1351 | compatibility with this should carry the burden for |
1352 | supporting this themselves and patch support for these back | |
1353 | in, if they really need to. Also, the facilities $syslog and | |
1354 | $local_fs are now ignored, since systemd does not support | |
1355 | early-boot LSB init scripts anymore, and these facilities | |
1356 | are implied anyway for normal services. syslog.target has | |
1357 | also been removed. | |
85d68397 | 1358 | |
40e21da8 | 1359 | * There are new bus calls on PID1's Manager object for |
6aa8d43a | 1360 | cancelling jobs, and removing snapshot units. Previously, |
85d68397 LP |
1361 | both calls were only available on the Job and Snapshot |
1362 | objects themselves. | |
1363 | ||
1364 | * systemd-journal-gatewayd gained SSL support. | |
1365 | ||
1366 | * The various "environment" files, such as /etc/locale.conf | |
1367 | now support continuation lines with a backslash ("\") as | |
1368 | last character in the line, similar in style (but different) | |
1369 | to how this is supported in shells. | |
1370 | ||
1371 | * For normal user processes the _SYSTEMD_USER_UNIT= field is | |
1372 | now implicitly appended to every log entry logged. systemctl | |
1373 | has been updated to filter by this field when operating on a | |
1374 | user systemd instance. | |
1375 | ||
1376 | * nspawn will now implicitly add the CAP_AUDIT_WRITE and | |
1377 | CAP_AUDIT_CONTROL capabilities to the capabilities set for | |
1378 | the container. This makes it easier to boot unmodified | |
1379 | Fedora systems in a container, which however still requires | |
1380 | audit=0 to be passed on the kernel command line. Auditing in | |
1381 | kernel and userspace is unfortunately still too broken in | |
1382 | context of containers, hence we recommend compiling it out | |
1383 | of the kernel or using audit=0. Hopefully this will be fixed | |
1384 | one day for good in the kernel. | |
1385 | ||
1386 | * nspawn gained the new --bind= and --bind-ro= parameters to | |
1387 | bind mount specific directories from the host into the | |
1388 | container. | |
1389 | ||
40e21da8 | 1390 | * nspawn will now mount its own devpts file system instance |
6aa8d43a | 1391 | into the container, in order not to leak pty devices from |
85d68397 LP |
1392 | the host into the container. |
1393 | ||
1394 | * systemd will now read the firmware boot time performance | |
6aa8d43a LP |
1395 | information from the EFI variables, if the used boot loader |
1396 | supports this, and takes it into account for boot performance | |
1397 | analysis via "systemd-analyze". This is currently supported | |
1398 | only in conjunction with Gummiboot, but could be supported | |
1399 | by other boot loaders too. For details see: | |
85d68397 LP |
1400 | |
1401 | http://www.freedesktop.org/wiki/Software/systemd/BootLoaderInterface | |
1402 | ||
1403 | * A new generator has been added that automatically mounts the | |
1404 | EFI System Partition (ESP) to /boot, if that directory | |
6aa8d43a LP |
1405 | exists, is empty, and no other file system has been |
1406 | configured to be mounted there. | |
85d68397 LP |
1407 | |
1408 | * logind will now send out PrepareForSleep(false) out | |
1409 | unconditionally, after coming back from suspend. This may be | |
1410 | used by applications as asynchronous notification for | |
1411 | system resume events. | |
1412 | ||
1413 | * "systemctl unlock-sessions" has been added, that allows | |
1414 | unlocking the screens of all user sessions at once, similar | |
1415 | how "systemctl lock-sessions" already locked all users | |
40e21da8 | 1416 | sessions. This is backed by a new D-Bus call UnlockSessions(). |
85d68397 LP |
1417 | |
1418 | * "loginctl seat-status" will now show the master device of a | |
1419 | seat. (i.e. the device of a seat that needs to be around for | |
1420 | the seat to be considered available, usually the graphics | |
1421 | card). | |
1422 | ||
1423 | * tmpfiles gained a new "X" line type, that allows | |
1424 | configuration of files and directories (with wildcards) that | |
1425 | shall be excluded from automatic cleanup ("aging"). | |
1426 | ||
bf933560 KS |
1427 | * udev default rules set the device node permissions now only |
1428 | at "add" events, and do not change them any longer with a | |
1429 | later "change" event. | |
85d68397 LP |
1430 | |
1431 | * The log messages for lid events and power/sleep keypresses | |
1432 | now carry a message ID. | |
1433 | ||
1434 | * We now have a substantially larger unit test suite, but this | |
1435 | continues to be work in progress. | |
1436 | ||
1437 | * udevadm hwdb gained a new --root= parameter to change the | |
1438 | root directory to operate relative to. | |
1439 | ||
40e21da8 KS |
1440 | * logind will now issue a background sync() request to the kernel |
1441 | early at shutdown, so that dirty buffers are flushed to disk early | |
85d68397 LP |
1442 | instead of at the last moment, in order to optimize shutdown |
1443 | times a little. | |
1444 | ||
1445 | * A new bootctl tool has been added that is an interface for | |
1446 | certain boot loader operations. This is currently a preview | |
1447 | and is likely to be extended into a small mechanism daemon | |
1448 | like timedated, localed, hostnamed, and can be used by | |
1449 | graphical UIs to enumerate available boot options, and | |
1450 | request boot into firmware operations. | |
1451 | ||
1452 | * systemd-bootchart has been relicensed to LGPLv2.1+ to match | |
1453 | the rest of the package. It also has been updated to work | |
1454 | correctly in initrds. | |
1455 | ||
1456 | * Policykit previously has been runtime optional, and is now | |
1457 | also compile time optional via a configure switch. | |
1458 | ||
1459 | * systemd-analyze has been reimplemented in C. Also "systemctl | |
1460 | dot" has moved into systemd-analyze. | |
1461 | ||
1462 | * "systemctl status" with no further parameters will now print | |
1463 | the status of all active or failed units. | |
1464 | ||
1465 | * Operations such as "systemctl start" can now be executed | |
1466 | with a new mode "--irreversible" which may be used to queue | |
1467 | operations that cannot accidentally be reversed by a later | |
6aa8d43a | 1468 | job queuing. This is by default used to make shutdown |
85d68397 LP |
1469 | requests more robust. |
1470 | ||
1471 | * The Python API of systemd now gained a new module for | |
1472 | reading journal files. | |
1473 | ||
1474 | * A new tool kernel-install has been added that can install | |
1475 | kernel images according to the Boot Loader Specification: | |
1476 | ||
1477 | http://www.freedesktop.org/wiki/Specifications/BootLoaderSpec | |
1478 | ||
1479 | * Boot time console output has been improved to provide | |
6aa8d43a | 1480 | animated boot time output for hanging jobs. |
85d68397 LP |
1481 | |
1482 | * A new tool systemd-activate has been added which can be used | |
1483 | to test socket activation with, directly from the command | |
1484 | line. This should make it much easier to test and debug | |
1485 | socket activation in daemons. | |
1486 | ||
1487 | * journalctl gained a new "--reverse" (or -r) option to show | |
1488 | journal output in reverse order (i.e. newest line first). | |
1489 | ||
43447fb7 LP |
1490 | * journalctl gained a new "--pager-end" (or -e) option to jump |
1491 | to immediately jump to the end of the journal in the | |
1492 | pager. This is only supported in conjunction with "less". | |
1493 | ||
85d68397 LP |
1494 | * journalctl gained a new "--user-unit=" option, that works |
1495 | similar to "--unit=" but filters for user units rather than | |
1496 | system units. | |
1497 | ||
1498 | * A number of unit files to ease adoption of systemd in | |
1499 | initrds has been added. This moves some minimal logic from | |
1500 | the various initrd implementations into systemd proper. | |
1501 | ||
1502 | * The journal files are now owned by a new group | |
1503 | "systemd-journal", which exists specifically to allow access | |
1504 | to the journal, and nothing else. Previously, we used the | |
6aa8d43a | 1505 | "adm" group for that, which however possibly covers more |
85d68397 LP |
1506 | than just journal/log file access. This new group is now |
1507 | already used by systemd-journal-gatewayd to ensure this | |
1508 | daemon gets access to the journal files and as little else | |
1509 | as possible. Note that "make install" will also set FS ACLs | |
1510 | up for /var/log/journal to give "adm" and "wheel" read | |
1511 | access to it, in addition to "systemd-journal" which owns | |
1512 | the journal files. We recommend that packaging scripts also | |
6aa8d43a | 1513 | add read access to "adm" + "wheel" to /var/log/journal, and |
85d68397 LP |
1514 | all existing/future journal files. To normal users and |
1515 | administrators little changes, however packagers need to | |
1516 | ensure to create the "systemd-journal" system group at | |
1517 | package installation time. | |
1518 | ||
1519 | * The systemd-journal-gatewayd now runs as unprivileged user | |
1520 | systemd-journal-gateway:systemd-journal-gateway. Packaging | |
1521 | scripts need to create these system user/group at | |
1522 | installation time. | |
1523 | ||
1524 | * timedated now exposes a new boolean property CanNTP that | |
1525 | indicates whether a local NTP service is available or not. | |
1526 | ||
1527 | * systemd-detect-virt will now also detect xen PVs | |
1528 | ||
40e21da8 KS |
1529 | * The pstore file system is now mounted by default, if it is |
1530 | available. | |
85d68397 | 1531 | |
1aed4590 LP |
1532 | * In addition to the SELinux and IMA policies we will now also |
1533 | load SMACK policies at early boot. | |

1550 | CHANGES WITH 197: |
1551 | ||
1552 | * Timer units now support calendar time events in addition to | |
1553 | monotonic time events. That means you can now trigger a unit | |
1554 | based on a calendar time specification such as "Thu,Fri | |
1555 | 2013-*-1,5 11:12:13" which refers to 11:12:13 of the first | |
1556 | or fifth day of any month of the year 2013, given that it is | |
1557 | a thursday or friday. This brings timer event support | |
1558 | considerably closer to cron's capabilities. For details on | |
1559 | the supported calendar time specification language see | |
1560 | systemd.time(7). | |
1561 | ||
1562 | * udev now supports a number of different naming policies for | |
1563 | network interfaces for predictable names, and a combination | |
1564 | of these policies is now the default. Please see this wiki | |
1565 | document for details: | |
1566 | ||
1567 | http://www.freedesktop.org/wiki/Software/systemd/PredictableNetworkInterfaceNames | |
1568 | ||
1569 | * Auke Kok's bootchart implementation has been added to the | |
1570 | systemd tree. It's an optional component that can graph the | |
1571 | boot in quite some detail. It's one of the best bootchart | |
1572 | implementations around and minimal in its code and | |
1573 | dependencies. | |
1574 | ||
1575 | * nss-myhostname has been integrated into the systemd source | |
1576 | tree. nss-myhostname guarantees that the local hostname | |
1577 | always stays resolvable via NSS. It has been a weak | |
1578 | requirement of systemd-hostnamed since a long time, and | |
1579 | since its code is actually trivial we decided to just | |
1580 | include it in systemd's source tree. It can be turned off | |
1581 | with a configure switch. | |
1582 | ||
1583 | * The read-ahead logic is now capable of properly detecting | |
1584 | whether a btrfs file system is on SSD or rotating media, in | |
1585 | order to optimize the read-ahead scheme. Previously, it was | |
1586 | only capable of detecting this on traditional file systems | |
1587 | such as ext4. | |
1588 | ||
1589 | * In udev, additional device properties are now read from the | |
1590 | IAB in addition to the OUI database. Also, Bluetooth company | |
1591 | identities are attached to the devices as well. | |
1592 | ||
1593 | * In service files %U may be used as specifier that is | |
1594 | replaced by the configured user name of the service. | |
1595 | ||
1596 | * nspawn may now be invoked without a controlling TTY. This | |
1597 | makes it suitable for invocation as its own service. This | |
1598 | may be used to set up a simple containerized server system | |
1599 | using only core OS tools. | |
1600 | ||
1601 | * systemd and nspawn can now accept socket file descriptors | |
1602 | when they are started for socket activation. This enables | |
1603 | implementation of socket activated nspawn | |
1604 | containers. i.e. think about autospawning an entire OS image | |
1605 | when the first SSH or HTTP connection is received. We expect | |
1606 | that similar functionality will also be added to libvirt-lxc | |
1607 | eventually. | |
1608 | ||
1609 | * journalctl will now suppress ANSI color codes when | |
1610 | presenting log data. | |
1611 | ||
1612 | * systemctl will no longer show control group information for | |
1613 | a unit if a the control group is empty anyway. | |
1614 | ||
1615 | * logind can now automatically suspend/hibernate/shutdown the | |
1616 | system on idle. | |
1617 | ||
1618 | * /etc/machine-info and hostnamed now also expose the chassis | |
1619 | type of the system. This can be used to determine whether | |
1620 | the local system is a laptop, desktop, handset or | |
1621 | tablet. This information may either be configured by the | |
1622 | user/vendor or is automatically determined from ACPI and DMI | |
1623 | information if possible. | |
1624 | ||
1625 | * A number of PolicyKit actions are now bound together with | |
1626 | "imply" rules. This should simplify creating UIs because | |
1627 | many actions will now authenticate similar ones as well. | |
1628 | ||
1629 | * Unit files learnt a new condition ConditionACPower= which | |
1630 | may be used to conditionalize a unit depending on whether an | |
1631 | AC power source is connected or not, of whether the system | |
1632 | is running on battery power. | |
1633 | ||
1634 | * systemctl gained a new "is-failed" verb that may be used in | |
1635 | shell scripts and suchlike to check whether a specific unit | |
1636 | is in the "failed" state. | |
1637 | ||
1638 | * The EnvironmentFile= setting in unit files now supports file | |
1639 | globbing, and can hence be used to easily read a number of | |
1640 | environment files at once. | |
1641 | ||
1642 | * systemd will no longer detect and recognize specific | |
1643 | distributions. All distribution-specific #ifdeffery has been | |
1644 | removed, systemd is now fully generic and | |
1645 | distribution-agnostic. Effectively, not too much is lost as | |
1646 | a lot of the code is still accessible via explicit configure | |
1647 | switches. However, support for some distribution specific | |
1648 | legacy configuration file formats has been dropped. We | |
1649 | recommend distributions to simply adopt the configuration | |
1650 | files everybody else uses now and convert the old | |
1651 | configuration from packaging scripts. Most distributions | |
1652 | already did that. If that's not possible or desirable, | |
1653 | distributions are welcome to forward port the specific | |
1654 | pieces of code locally from the git history. | |
1655 | ||
1656 | * When logging a message about a unit systemd will now always | |
1657 | log the unit name in the message meta data. | |
1658 | ||
1659 | * localectl will now also discover system locale data that is | |
1660 | not stored in locale archives, but directly unpacked. | |
1661 | ||
1662 | * logind will no longer unconditionally use framebuffer | |
1663 | devices as seat masters, i.e. as devices that are required | |
1664 | to be existing before a seat is considered preset. Instead, | |
1665 | it will now look for all devices that are tagged as | |
1666 | "seat-master" in udev. By default framebuffer devices will | |
1667 | be marked as such, but depending on local systems other | |
1668 | devices might be marked as well. This may be used to | |
1669 | integrate graphics cards using closed source drivers (such | |
1670 | as NVidia ones) more nicely into logind. Note however, that | |
1671 | we recommend using the open source NVidia drivers instead, | |
1672 | and no udev rules for the closed-source drivers will be | |
1673 | shipped from us upstream. | |

1689 | CHANGES WITH 196: |
1690 | ||
1691 | * udev gained support for loading additional device properties | |
1692 | from an indexed database that is keyed by vendor/product IDs | |
1693 | and similar device identifiers. For the beginning this | |
1694 | "hwdb" is populated with data from the well-known PCI and | |
1695 | USB database, but also includes PNP, ACPI and OID data. In | |
1696 | the longer run this indexed database shall grow into | |
1697 | becoming the one central database for non-essential | |
1698 | userspace device metadata. Previously, data from the PCI/USB | |
96ec33c0 | 1699 | database was only attached to select devices, since the |
0428ddb7 | 1700 | lookup was a relatively expensive operation due to O(n) time |
96ec33c0 LP |
1701 | complexity (with n being the number of entries in the |
1702 | database). Since this is now O(1), we decided to add in this | |
1703 | data for all devices where this is available, by | |
0428ddb7 LP |
1704 | default. Note that the indexed database needs to be rebuilt |
1705 | when new data files are installed. To achieve this you need | |
1706 | to update your packaging scripts to invoke "udevadm hwdb | |
1707 | --update" after installation of hwdb data files. For | |
1708 | RPM-based distributions we introduced the new | |
1709 | %udev_hwdb_update macro for this purpose. | |
1710 | ||
1711 | * The Journal gained support for the "Message Catalog", an | |
1712 | indexed database to link up additional information with | |
1713 | journal entries. For further details please check: | |
1714 | ||
1715 | http://www.freedesktop.org/wiki/Software/systemd/catalog | |
1716 | ||
1717 | The indexed message catalog database also needs to be | |
1718 | rebuilt after installation of message catalog files. Use | |
1719 | "journalctl --update-catalog" for this. For RPM-based | |
1720 | distributions we introduced the %journal_catalog_update | |
1721 | macro for this purpose. | |
1722 | ||
1723 | * The Python Journal bindings gained support for the standard | |
1724 | Python logging framework. | |
1725 | ||
1726 | * The Journal API gained new functions for checking whether | |
1727 | the underlying file system of a journal file is capable of | |
1728 | properly reporting file change notifications, or whether | |
1729 | applications that want to reflect journal changes "live" | |
ab06eef8 | 1730 | need to recheck journal files continuously in appropriate |
0428ddb7 LP |
1731 | time intervals. |
1732 | ||
1733 | * It is now possible to set the "age" field for tmpfiles | |
1734 | entries to 0, indicating that files matching this entry | |
1735 | shall always be removed when the directories are cleaned up. | |
1736 | ||
1737 | * coredumpctl gained a new "gdb" verb which invokes gdb | |
1738 | right-away on the selected coredump. | |
1739 | ||
1740 | * There's now support for "hybrid sleep" on kernels that | |
1741 | support this, in addition to "suspend" and "hibernate". Use | |
1742 | "systemctl hybrid-sleep" to make use of this. | |
1743 | ||
1744 | * logind's HandleSuspendKey= setting (and related settings) | |
1745 | now gained support for a new "lock" setting to simply | |
1746 | request the screen lock on all local sessions, instead of | |
1747 | actually executing a suspend or hibernation. | |
1748 | ||
1749 | * systemd will now mount the EFI variables file system by | |
1750 | default. | |
1751 | ||
1752 | * Socket units now gained support for configuration of the | |
1753 | SMACK security label. | |
1754 | ||
1755 | * timedatectl will now output the time of the last and next | |
1756 | daylight saving change. | |
1757 | ||
1758 | * We dropped support for various legacy and distro-specific | |
1759 | concepts, such as insserv, early-boot SysV services | |
1760 | (i.e. those for non-standard runlevels such as 'b' or 'S') | |
1761 | or ArchLinux /etc/rc.conf support. We recommend the | |
1762 | distributions who still need support this to either continue | |
1763 | to maintain the necessary patches downstream, or find a | |
1764 | different solution. (Talk to us if you have questions!) | |
1765 | ||
1766 | * Various systemd components will now bypass PolicyKit checks | |
1767 | for root and otherwise handle properly if PolicyKit is not | |
1768 | found to be around. This should fix most issues for | |
1769 | PolicyKit-less systems. Quite frankly this should have been | |
1770 | this way since day one. It is absolutely our intention to | |
1771 | make systemd work fine on PolicyKit-less systems, and we | |
1772 | consider it a bug if something doesn't work as it should if | |
1773 | PolicyKit is not around. | |
1774 | ||
1775 | * For embedded systems it is now possible to build udev and | |
1776 | systemd without blkid and/or kmod support. | |
1777 | ||
1778 | * "systemctl switch-root" is now capable of switching root | |
1779 | more than once. I.e. in addition to transitions from the | |
1780 | initrd to the host OS it is now possible to transition to | |
1781 | further OS images from the host. This is useful to implement | |
1782 | offline updating tools. | |
1783 | ||
1784 | * Various other additions have been made to the RPM macros | |
1785 | shipped with systemd. Use %udev_rules_update() after | |
1786 | installing new udev rules files. %_udevhwdbdir, | |
1787 | %_udevrulesdir, %_journalcatalogdir, %_tmpfilesdir, | |
1788 | %_sysctldir are now available which resolve to the right | |
1789 | directories for packages to place various data files in. | |
1790 | ||
1791 | * journalctl gained the new --full switch (in addition to | |
1792 | --all, to disable ellipsation for long messages. | |

139ee8cc LP |
1804 | CHANGES WITH 195: |
1805 | ||
6827101a | 1806 | * journalctl gained new --since= and --until= switches to |
139ee8cc LP |
1807 | filter by time. It also now supports nice filtering for |
1808 | units via --unit=/-u. | |
1809 | ||
6827101a | 1810 | * Type=oneshot services may use ExecReload= and do the |
139ee8cc LP |
1811 | right thing. |
1812 | ||
1813 | * The journal daemon now supports time-based rotation and | |
1814 | vacuuming, in addition to the usual disk-space based | |
1815 | rotation. | |
1816 | ||
1817 | * The journal will now index the available field values for | |
1818 | each field name. This enables clients to show pretty drop | |
1819 | downs of available match values when filtering. The bash | |
1820 | completion of journalctl has been updated | |
1821 | accordingly. journalctl gained a new switch -F to list all | |
1822 | values a certain field takes in the journal database. | |
1823 | ||
1824 | * More service events are now written as structured messages | |
1825 | to the journal, and made recognizable via message IDs. | |
1826 | ||
1827 | * The timedated, localed and hostnamed mini-services which | |
1828 | previously only provided support for changing time, locale | |
1829 | and hostname settings from graphical DEs such as GNOME now | |
1830 | also have a minimal (but very useful) text-based client | |
1831 | utility each. This is probably the nicest way to changing | |
1832 | these settings from the command line now, especially since | |
1833 | it lists available options and is fully integrated with bash | |
1834 | completion. | |
1835 | ||
1836 | * There's now a new tool "systemd-coredumpctl" to list and | |
1837 | extract coredumps from the journal. | |
1838 | ||
1839 | * We now install a README each in /var/log/ and | |
1840 | /etc/rc.d/init.d explaining where the system logs and init | |
1841 | scripts went. This hopefully should help folks who go to | |
1842 | that dirs and look into the otherwise now empty void and | |
1843 | scratch their heads. | |
1844 | ||
1845 | * When user-services are invoked (by systemd --user) the | |
1846 | $MANAGERPID env var is set to the PID of systemd. | |
1847 | ||
1848 | * SIGRTMIN+24 when sent to a --user instance will now result | |
1849 | in immediate termination of systemd. | |
1850 | ||
1851 | * gatewayd received numerous feature additions such as a | |
1852 | "follow" mode, for live syncing and filtering. | |
1853 | ||
1854 | * browse.html now allows filtering and showing detailed | |
1855 | information on specific entries. Keyboard navigation and | |
1856 | mouse screen support has been added. | |
1857 | ||
1858 | * gatewayd/journalctl now supports HTML5/JSON | |
1859 | Server-Sent-Events as output. | |
1860 | ||
1cb88f2c | 1861 | * The SysV init script compatibility logic will now |
139ee8cc LP |
1862 | heuristically determine whether a script supports the |
1863 | "reload" verb, and only then make this available as | |
1864 | "systemctl reload". | |
1865 | ||
15f47220 | 1866 | * "systemctl status --follow" has been removed, use "journalctl |
139ee8cc LP |
1867 | -u" instead. |
1868 | ||
1869 | * journald.conf's RuntimeMinSize=, PersistentMinSize= settings | |
1870 | have been removed since they are hardly useful to be | |
1871 | configured. | |
1872 | ||
1873 | * And I'd like to take the opportunity to specifically mention | |
1874 | Zbigniew for his great contributions. Zbigniew, you rock! | |

1884 | CHANGES WITH 194: |
1885 | ||
1886 | * If /etc/vconsole.conf is non-existent or empty we will no | |
1887 | longer load any console font or key map at boot by | |
1888 | default. Instead the kernel defaults will be left | |
1889 | intact. This is definitely the right thing to do, as no | |
1890 | configuration should mean no configuration, and hard-coding | |
1891 | font names that are different on all archs is probably a bad | |
1892 | idea. Also, the kernel default key map and font should be | |
1893 | good enough for most cases anyway, and mostly identical to | |
1894 | the userspace fonts/key maps we previously overloaded them | |
1895 | with. If distributions want to continue to default to a | |
1896 | non-kernel font or key map they should ship a default | |
1897 | /etc/vconsole.conf with the appropriate contents. | |

597c52cf LP |
1903 | CHANGES WITH 193: |
1904 | ||
1905 | * journalctl gained a new --cursor= switch to show entries | |
1906 | starting from the specified location in the journal. | |
1907 | ||
1908 | * We now enforce a size limit on journal entry fields exported | |
1909 | with "-o json" in journalctl. Fields larger than 4K will be | |
1910 | assigned null. This can be turned off with --all. | |
1911 | ||
1912 | * An (optional) journal gateway daemon is now available as | |
1913 | "systemd-journal-gatewayd.service". This service provides | |
1914 | access to the journal via HTTP and JSON. This functionality | |
1915 | will be used to implement live log synchronization in both | |
1916 | pull and push modes, but has various other users too, such | |
1917 | as easy log access for debugging of embedded devices. Right | |
1918 | now it is already useful to retrieve the journal via HTTP: | |
1919 | ||
1920 | # systemctl start systemd-journal-gatewayd.service | |
1921 | # wget http://localhost:19531/entries | |
1922 | ||
1923 | This will download the journal contents in a | |
1924 | /var/log/messages compatible format. The same as JSON: | |
1925 | ||
1926 | # curl -H"Accept: application/json" http://localhost:19531/entries | |
1927 | ||
1928 | This service is also accessible via a web browser where a | |
1929 | single static HTML5 app is served that uses the JSON logic | |
1930 | to enable the user to do some basic browsing of the | |
1931 | journal. This will be extended later on. Here's an example | |
1932 | screenshot of this app in its current state: | |

1940 | ||
1941 | * The bash completion logic is now available for journalctl | |
1942 | too. | |
1943 | ||
1944 | * We don't mount the "cpuset" controller anymore together with | |
1945 | "cpu" and "cpuacct", as "cpuset" groups generally cannot be | |
1946 | started if no parameters are assigned to it. "cpuset" hence | |
1947 | broke code that assumed it it could create "cpu" groups and | |
1948 | just start them. | |
1949 | ||
1950 | * journalctl -f will now subscribe to terminal size changes, | |
1951 | and line break accordingly. | |

b6a86739 LP |
1956 | CHANGES WITH 191: |
1957 | ||
1958 | * nspawn will now create a symlink /etc/localtime in the | |
1959 | container environment, copying the host's timezone | |
1960 | setting. Previously this has been done via a bind mount, but | |
1961 | since symlinks cannot be bind mounted this has now been | |
1962 | changed to create/update the appropriate symlink. | |
1963 | ||
1964 | * journalctl -n's line number argument is now optional, and | |
1965 | will default to 10 if omitted. | |
1966 | ||
1967 | * journald will now log the maximum size the journal files may | |
1968 | take up on disk. This is particularly useful if the default | |
1969 | built-in logic of determining this parameter from the file | |
1970 | system size is used. Use "systemctl status | |
6563b535 | 1971 | systemd-journald.service" to see this information. |
b6a86739 LP |
1972 | |
1973 | * The multi-seat X wrapper tool has been stripped down. As X | |
1974 | is now capable of enumerating graphics devices via udev in a | |
1975 | seat-aware way the wrapper is not strictly necessary | |
1976 | anymore. A stripped down temporary stop-gap is still shipped | |
1977 | until the upstream display managers have been updated to | |
1978 | fully support the new X logic. Expect this wrapper to be | |
6563b535 | 1979 | removed entirely in one of the next releases. |
b6a86739 LP |
1980 | |
1981 | * HandleSleepKey= in logind.conf has been split up into | |
1982 | HandleSuspendKey= and HandleHibernateKey=. The old setting | |
6563b535 | 1983 | is not available anymore. X11 and the kernel are |
b6a86739 LP |
1984 | distuingishing between these keys and we should too. This |
1985 | also means the inhibition lock for these keys has been split | |
1986 | into two. | |

0c11f949 LP |
1991 | CHANGES WITH 190: |
1992 | ||
1993 | * Whenever a unit changes state we'll now log this to the | |
1994 | journal and show along the unit's own log output in | |
1995 | "systemctl status". | |
1996 | ||
1997 | * ConditionPathIsMountPoint= can now properly detect bind | |
1998 | mount points too. (Previously, a bind mount of one file | |
8d0256b7 | 1999 | system to another place in the same file system could not be |
0c11f949 LP |
2000 | detected as mount, since they shared struct stat's st_dev |
2001 | field.) | |

2003 | * We will now mount the cgroup controllers cpu, cpuacct, | |
2004 | cpuset and the controllers net_cls, net_prio together by | |
2005 | default. | |
2006 | ||
2007 | * nspawn containers will now have a virtualized boot | |
2008 | ID. (i.e. /proc/sys/kernel/random/boot_id is now mounted | |
2009 | over with a randomized ID at container initialization). This | |
2010 | has the effect of making "journalctl -b" do the right thing | |
2011 | in a container. | |
2012 | ||
2013 | * The JSON output journal serialization has been updated not | |
2014 | to generate "endless" list objects anymore, but rather one | |
2015 | JSON object per line. This is more in line how most JSON | |
2016 | parsers expect JSON objects. The new output mode | |
2017 | "json-pretty" has been added to provide similar output, but | |
2018 | neatly aligned for readability by humans. | |
2019 | ||
2020 | * We dropped all explicit sync() invocations in the shutdown | |
2021 | code. The kernel does this implicitly anyway in the kernel | |
2022 | reboot() syscall. halt(8)'s -n option is now a compatibility | |
2023 | no-op. | |
2024 | ||
2025 | * We now support virtualized reboot() in containers, as | |
2026 | supported by newer kernels. We will fall back to exit() if | |
2027 | CAP_SYS_REBOOT is not available to the container. Also, | |
2028 | nspawn makes use of this now and will actually reboot the | |
2029 | container if the containerized OS asks for that. | |
2030 | ||
2031 | * journalctl will only show local log output by default | |
2032 | now. Use --merge (-m) to show remote log output, too. | |
2033 | ||
2034 | * libsystemd-journal gained the new sd_journal_get_usage() | |
2035 | call to determine the current disk usage of all journal | |
2036 | files. This is exposed in the new "journalctl --disk-usage" | |
2037 | command. | |
2038 | ||
2039 | * journald gained a new configuration setting SplitMode= in | |
2040 | journald.conf which may be used to control how user journals | |
2041 | are split off. See journald.conf(5) for details. | |
2042 | ||
2043 | * A new condition type ConditionFileNotEmpty= has been added. | |
2044 | ||
2045 | * tmpfiles' "w" lines now support file globbing, to write | |
2046 | multiple files at once. | |
2047 | ||
2048 | * We added Python bindings for the journal submission | |
2049 | APIs. More Python APIs for a number of selected APIs will | |
2050 | likely follow. Note that we intend to add native bindings | |
2051 | only for the Python language, as we consider it common | |
2052 | enough to deserve bindings shipped within systemd. There are | |
2053 | various projects outside of systemd that provide bindings | |
2054 | for languages such as PHP or Lua. | |
2055 | ||
a98d5d64 LP |
2056 | * Many conditions will now resolve specifiers such as %i. In |
2057 | addition, PathChanged= and related directives of .path units | |
2058 | now support specifiers as well. | |
0c11f949 LP |
2059 | |
2060 | * There's now a new RPM macro definition for the system preset | |
2061 | dir: %_presetdir. | |
2062 | ||
ab06eef8 | 2063 | * journald will now warn if it can't forward a message to the |
0c11f949 LP |
2064 | syslog daemon because it's socket is full. |
2065 | ||
2066 | * timedated will no longer write or process /etc/timezone, | |
2067 | except on Debian. As we do not support late mounted /usr | |
2068 | anymore /etc/localtime always being a symlink is now safe, | |
2069 | and hence the information in /etc/timezone is not necessary | |
2070 | anymore. | |
2071 | ||
aaccc32c | 2072 | * logind will now always reserve one VT for a text getty (VT6 |
0c11f949 LP |
2073 | by default). Previously if more than 6 X sessions where |
2074 | started they took up all the VTs with auto-spawned gettys, | |
2075 | so that no text gettys were available anymore. | |
2076 | ||
2077 | * udev will now automatically inform the btrfs kernel logic | |
2078 | about btrfs RAID components showing up. This should make | |
2079 | simple hotplug based btrfs RAID assembly work. | |
2080 | ||
2081 | * PID 1 will now increase its RLIMIT_NOFILE to 64K by default | |
2082 | (but not for its children which will stay at the kernel | |
2083 | default). This should allow setups with a lot more listening | |
2084 | sockets. | |
2085 | ||
2086 | * systemd will now always pass the configured timezone to the | |
2087 | kernel at boot. timedated will do the same when the timezone | |
2088 | is changed. | |
2089 | ||
2090 | * logind's inhibition logic has been updated. By default, | |
2091 | logind will now handle the lid switch, the power and sleep | |
2092 | keys all the time, even in graphical sessions. If DEs want | |
2093 | to handle these events on their own they should take the new | |
2094 | handle-power-key, handle-sleep-key and handle-lid-switch | |
2095 | inhibitors during their runtime. A simple way to achiveve | |
2096 | that is to invoke the DE wrapped in an invocation of: | |
2097 | ||
2098 | systemd-inhibit --what=handle-power-key:handle-sleep-key:handle-lid-switch ... | |
2099 | ||
2100 | * Access to unit operations is now checked via SELinux taking | |
2101 | the unit file label and client process label into account. | |
2102 | ||
aad803af LP |
2103 | * systemd will now notify the administrator in the journal |
2104 | when he over-mounts a non-empty directory. | |
2105 | ||
2106 | * There are new specifiers that are resolved in unit files, | |
2107 | for the host name (%H), the machine ID (%m) and the boot ID | |
2108 | (%b). | |

2118 | CHANGES WITH 189: |
2119 | ||
2120 | * Support for reading structured kernel messages from | |
2121 | /dev/kmsg has now been added and is enabled by default. | |
2122 | ||
2123 | * Support for reading kernel messages from /proc/kmsg has now | |
2124 | been removed. If you want kernel messages in the journal | |
2125 | make sure to run a recent kernel (>= 3.5) that supports | |
2126 | reading structured messages from /dev/kmsg (see | |
2127 | above). /proc/kmsg is now exclusive property of classic | |
2128 | syslog daemons again. | |
2129 | ||
2130 | * The libudev API gained the new | |
2131 | udev_device_new_from_device_id() call. | |
2132 | ||
2133 | * The logic for file system namespace (ReadOnlyDirectory=, | |
2134 | ReadWriteDirectoy=, PrivateTmp=) has been reworked not to | |
2135 | require pivot_root() anymore. This means fewer temporary | |
2136 | directories are created below /tmp for this feature. | |
2137 | ||
2138 | * nspawn containers will now see and receive all submounts | |
2139 | made on the host OS below the root file system of the | |
2140 | container. | |
2141 | ||
2142 | * Forward Secure Sealing is now supported for Journal files, | |
2143 | which provide cryptographical sealing of journal files so | |
2144 | that attackers cannot alter log history anymore without this | |
2145 | being detectable. Lennart will soon post a blog story about | |
2146 | this explaining it in more detail. | |
2147 | ||
2148 | * There are two new service settings RestartPreventExitStatus= | |
2149 | and SuccessExitStatus= which allow configuration of exit | |
2150 | status (exit code or signal) which will be excepted from the | |
2151 | restart logic, resp. consider successful. | |
2152 | ||
2153 | * journalctl gained the new --verify switch that can be used | |
2154 | to check the integrity of the structure of journal files and | |
2155 | (if Forward Secure Sealing is enabled) the contents of | |
2156 | journal files. | |
2157 | ||
2158 | * nspawn containers will now be run with /dev/stdin, /dev/fd/ | |
2159 | and similar symlinks pre-created. This makes running shells | |
2160 | as container init process a lot more fun. | |
2161 | ||
2162 | * The fstab support can now handle PARTUUID= and PARTLABEL= | |
2163 | entries. | |
2164 | ||
2165 | * A new ConditionHost= condition has been added to match | |
2166 | against the hostname (with globs) and machine ID. This is | |
2167 | useful for clusters where a single OS image is used to | |
2168 | provision a large number of hosts which shall run slightly | |
2169 | different sets of services. | |
2170 | ||
2171 | * Services which hit the restart limit will now be placed in a | |
2172 | failure state. | |

c269cec3 LP |
2178 | CHANGES WITH 188: |
2179 | ||
2180 | * When running in --user mode systemd will now become a | |
2181 | subreaper (PR_SET_CHILD_SUBREAPER). This should make the ps | |
2182 | tree a lot more organized. | |
2183 | ||
2184 | * A new PartOf= unit dependency type has been introduced that | |
2185 | may be used to group services in a natural way. | |
2186 | ||
2187 | * "systemctl enable" may now be used to enable instances of | |
2188 | services. | |
2189 | ||
2190 | * journalctl now prints error log levels in red, and | |
2191 | warning/notice log levels in bright white. It also supports | |
2192 | filtering by log level now. | |
2193 | ||
2194 | * cgtop gained a new -n switch (similar to top), to configure | |
2195 | the maximum number of iterations to run for. It also gained | |
2196 | -b, to run in batch mode (accepting no input). | |
2197 | ||
ab06eef8 | 2198 | * The suffix ".service" may now be omitted on most systemctl |
c269cec3 LP |
2199 | command lines involving service unit names. |
2200 | ||
2201 | * There's a new bus call in logind to lock all sessions, as | |
2202 | well as a loginctl verb for it "lock-sessions". | |
2203 | ||
2204 | * libsystemd-logind.so gained a new call sd_journal_perror() | |
2205 | that works similar to libc perror() but logs to the journal | |
2206 | and encodes structured information about the error number. | |
2207 | ||
2208 | * /etc/crypttab entries now understand the new keyfile-size= | |
2209 | option. | |
2210 | ||
2211 | * shutdown(8) now can send a (configurable) wall message when | |
2212 | a shutdown is cancelled. | |
2213 | ||
2214 | * The mount propagation mode for the root file system will now | |
2215 | default to "shared", which is useful to make containers work | |
2216 | nicely out-of-the-box so that they receive new mounts from | |
2217 | the host. This can be undone locally by running "mount | |
2218 | --make-rprivate /" if needed. | |
2219 | ||
2220 | * The prefdm.service file has been removed. Distributions | |
2221 | should maintain this unit downstream if they intend to keep | |
2222 | it around. However, we recommend writing normal unit files | |
2223 | for display managers instead. | |
2224 | ||
2225 | * Since systemd is a crucial part of the OS we will now | |
2226 | default to a number of compiler switches that improve | |
2227 | security (hardening) such as read-only relocations, stack | |
2228 | protection, and suchlike. | |
2229 | ||
2230 | * The TimeoutSec= setting for services is now split into | |
2231 | TimeoutStartSec= and TimeoutStopSec= to allow configuration | |
2232 | of individual time outs for the start and the stop phase of | |
2233 | the service. | |

c4f1b862 LP |
2242 | CHANGES WITH 187: |
2243 | ||
2244 | * The journal and id128 C APIs are now fully documented as man | |
2245 | pages. | |
2246 | ||
2247 | * Extra safety checks have been added when transitioning from | |
2248 | the initial RAM disk to the main system to avoid accidental | |
2249 | data loss. | |
2250 | ||
c269cec3 | 2251 | * /etc/crypttab entries now understand the new keyfile-offset= |
c4f1b862 LP |
2252 | option. |
2253 | ||
2254 | * systemctl -t can now be used to filter by unit load state. | |
2255 | ||
2256 | * The journal C API gained the new sd_journal_wait() call to | |
2257 | make writing synchronous journal clients easier. | |
2258 | ||
2259 | * journalctl gained the new -D switch to show journals from a | |
2260 | specific directory. | |
2261 | ||
2262 | * journalctl now displays a special marker between log | |
2263 | messages of two different boots. | |
2264 | ||
2265 | * The journal is now explicitly flushed to /var via a service | |
2266 | systemd-journal-flush.service, rather than implicitly simply | |
2267 | by seeing /var/log/journal to be writable. | |
2268 | ||
2269 | * journalctl (and the journal C APIs) can now match for much | |
2270 | more complex expressions, with alternatives and | |
2271 | disjunctions. | |
2272 | ||
2273 | * When transitioning from the initial RAM disk to the main | |
2274 | system we will now kill all processes in a killing spree to | |
2275 | ensure no processes stay around by accident. | |
2276 | ||
2277 | * Three new specifiers may be used in unit files: %u, %h, %s | |
2278 | resolve to the user name, user home directory resp. user | |
2279 | shell. This is useful for running systemd user instances. | |
2280 | ||
2281 | * We now automatically rotate journal files if their data | |
2282 | object hash table gets a fill level > 75%. We also size the | |
2283 | hash table based on the configured maximum file size. This | |
2284 | together should lower hash collisions drastically and thus | |
2285 | speed things up a bit. | |
2286 | ||
2287 | * journalctl gained the new "--header" switch to introspect | |
2288 | header data of journal files. | |
2289 | ||
2290 | * A new setting SystemCallFilters= has been added to services | |
2291 | which may be used to apply blacklists or whitelists to | |
2292 | system calls. This is based on SECCOMP Mode 2 of Linux 3.5. | |
2293 | ||
2294 | * nspawn gained a new --link-journal= switch (and quicker: -j) | |
2295 | to link the container journal with the host. This makes it | |
2296 | very easy to centralize log viewing on the host for all | |
2297 | guests while still keeping the journal files separated. | |
2298 | ||
2299 | * Many bugfixes and optimizations | |

b5b4c94a LP |
2306 | CHANGES WITH 186: |
2307 | ||
2308 | * Several tools now understand kernel command line arguments, | |
2309 | which are only read when run in an initial RAM disk. They | |
2310 | usually follow closely their normal counterparts, but are | |
2311 | prefixed with rd. | |
2312 | ||
2313 | * There's a new tool to analyze the readahead files that are | |
2314 | automatically generated at boot. Use: | |
2315 | ||
2316 | /usr/lib/systemd/systemd-readahead analyze /.readahead | |
2317 | ||
2318 | * We now provide an early debug shell on tty9 if this enabled. Use: | |
2319 | ||
d1f9edaf | 2320 | systemctl enable debug-shell.service |
b5b4c94a LP |
2321 | |
2322 | * All plymouth related units have been moved into the Plymouth | |
2323 | package. Please make sure to upgrade your Plymouth version | |
2324 | as well. | |
2325 | ||
2326 | * systemd-tmpfiles now supports getting passed the basename of | |
2327 | a configuration file only, in which case it will look for it | |
2328 | in all appropriate directories automatically. | |
2329 | ||
2330 | * udevadm info now takes a /dev or /sys path as argument, and | |
2331 | does the right thing. Example: | |
2332 | ||
2333 | udevadm info /dev/sda | |
2334 | udevadm info /sys/class/block/sda | |
2335 | ||
2336 | * systemctl now prints a warning if a unit is stopped but a | |
2337 | unit that might trigger it continues to run. Example: a | |
2338 | service is stopped but the socket that activates it is left | |
2339 | running. | |
2340 | ||
2341 | * "systemctl status" will now mention if the log output was | |
2342 | shortened due to rotation since a service has been started. | |
2343 | ||
2344 | * The journal API now exposes functions to determine the | |
2345 | "cutoff" times due to rotation. | |
2346 | ||
2347 | * journald now understands SIGUSR1 and SIGUSR2 for triggering | |
2348 | immediately flushing of runtime logs to /var if possible, | |
2349 | resp. for triggering immediate rotation of the journal | |
2350 | files. | |
2351 | ||
2352 | * It is now considered an error if a service is attempted to | |
2353 | be stopped that is not loaded. | |
2354 | ||
2355 | * XDG_RUNTIME_DIR now uses numeric UIDs instead of usernames. | |
2356 | ||
2357 | * systemd-analyze now supports Python 3 | |
2358 | ||
2359 | * tmpfiles now supports cleaning up directories via aging | |
2360 | where the first level dirs are always kept around but | |
2361 | directories beneath it automatically aged. This is enabled | |
2362 | by prefixing the age field with '~'. | |
2363 | ||
2364 | * Seat objects now expose CanGraphical, CanTTY properties | |
2365 | which is required to deal with very fast bootups where the | |
2366 | display manager might be running before the graphics drivers | |
2367 | completed initialization. | |
2368 | ||
2369 | * Seat objects now expose a State property. | |
2370 | ||
2371 | * We now include RPM macros for service enabling/disabling | |
2372 | based on the preset logic. We recommend RPM based | |
2373 | distributions to make use of these macros if possible. This | |
2374 | makes it simpler to reuse RPM spec files across | |
2375 | distributions. | |
2376 | ||
2377 | * We now make sure that the collected systemd unit name is | |
2378 | always valid when services log to the journal via | |
2379 | STDOUT/STDERR. | |
2380 | ||
2381 | * There's a new man page kernel-command-line(7) detailing all | |
2382 | command line options we understand. | |
2383 | ||
2384 | * The fstab generator may now be disabled at boot by passing | |
2385 | fstab=0 on the kernel command line. | |
2386 | ||
91ac7425 | 2387 | * A new kernel command line option modules-load= is now understood |
b5b4c94a LP |
2388 | to load a specific kernel module statically, early at boot. |
2389 | ||
2390 | * Unit names specified on the systemctl command line are now | |
2391 | automatically escaped as needed. Also, if file system or | |
2392 | device paths are specified they are automatically turned | |
2393 | into the appropriate mount or device unit names. Example: | |
2394 | ||
2395 | systemctl status /home | |
2396 | systemctl status /dev/sda | |
2397 | ||
2398 | * The SysVConsole= configuration option has been removed from | |
2399 | system.conf parsing. | |
2400 | ||
2401 | * The SysV search path is no longer exported on the D-Bus | |
2402 | Manager object. | |
2403 | ||
2404 | * The Names= option is been removed from unit file parsing. | |
2405 | ||
2406 | * There's a new man page bootup(7) detailing the boot process. | |
2407 | ||
2408 | * Every unit and every generator we ship with systemd now | |
2409 | comes with full documentation. The self-explanatory boot is | |
2410 | complete. | |
2411 | ||
2412 | * A couple of services gained "systemd-" prefixes in their | |
2413 | name if they wrap systemd code, rather than only external | |
2414 | code. Among them fsck@.service which is now | |
2415 | systemd-fsck@.service. | |
2416 | ||
2417 | * The HaveWatchdog property has been removed from the D-Bus | |
2418 | Manager object. | |
2419 | ||
2420 | * systemd.confirm_spawn= on the kernel command line should now | |
2421 | work sensibly. | |
2422 | ||
2423 | * There's a new man page crypttab(5) which details all options | |
2424 | we actually understand. | |
2425 | ||
2426 | * systemd-nspawn gained a new --capability= switch to pass | |
2427 | additional capabilities to the container. | |
2428 | ||
2429 | * timedated will now read known NTP implementation unit names | |
5b00c016 | 2430 | from /usr/lib/systemd/ntp-units.d/*.list, |
b5b4c94a LP |
2431 | systemd-timedated-ntp.target has been removed. |
2432 | ||
2433 | * journalctl gained a new switch "-b" that lists log data of | |
2434 | the current boot only. | |
2435 | ||
2436 | * The notify socket is in the abstract namespace again, in | |
2437 | order to support daemons which chroot() at start-up. | |
2438 | ||
2439 | * There is a new Storage= configuration option for journald | |
2440 | which allows configuration of where log data should go. This | |
2441 | also provides a way to disable journal logging entirely, so | |
2442 | that data collected is only forwarded to the console, the | |
2443 | kernel log buffer or another syslog implementation. | |
2444 | ||
c4f1b862 | 2445 | * Many bugfixes and optimizations |

2d197285 | 2452 | CHANGES WITH 185: |
b6a86739 | 2453 | |
2d197285 KS |
2454 | * "systemctl help <unit>" now shows the man page if one is |
2455 | available. | |
2456 | ||
2457 | * Several new man pages have been added. | |
2458 | ||
b5b4c94a LP |
2459 | * MaxLevelStore=, MaxLevelSyslog=, MaxLevelKMsg=, |
2460 | MaxLevelConsole= can now be specified in | |
2461 | journald.conf. These options allow reducing the amount of | |
2462 | data stored on disk or forwarded by the log level. | |
2d197285 | 2463 | |
b5b4c94a LP |
2464 | * TimerSlackNSec= can now be specified in system.conf for |
2465 | PID1. This allows system-wide power savings. | |

4c8cd173 LP |
2473 | * logind is now capable of (optionally) handling power and |
2474 | sleep keys as well as the lid switch. | |
2475 | ||
2476 | * journalctl now understands the syntax "journalctl | |
2477 | /usr/bin/avahi-daemon" to get all log output of a specific | |
2478 | daemon. | |
2479 | ||
2480 | * CapabilityBoundingSet= in system.conf now also influences | |
2481 | the capability bound set of usermode helpers of the kernel. | |

ea5943d3 | 2488 | CHANGES WITH 183: |
b6a86739 | 2489 | |
187076d4 LP |
2490 | * Note that we skipped 139 releases here in order to set the |
2491 | new version to something that is greater than both udev's | |
2492 | and systemd's most recent version number. | |
2493 | ||
194bbe33 KS |
2494 | * udev: all udev sources are merged into the systemd source tree now. |
2495 | All future udev development will happen in the systemd tree. It | |
2496 | is still fully supported to use the udev daemon and tools without | |
2497 | systemd running, like in initramfs or other init systems. Building | |
2498 | udev though, will require the *build* of the systemd tree, but | |
ea5943d3 | 2499 | udev can be properly *run* without systemd. |
07cd4fc1 | 2500 | |
91cf7e5c | 2501 | * udev: /lib/udev/devices/ are not read anymore; systemd-tmpfiles |
f13b388f KS |
2502 | should be used to create dead device nodes as workarounds for broken |
2503 | subsystems. | |
64661ee7 | 2504 | |
2d13da88 KS |
2505 | * udev: RUN+="socket:..." and udev_monitor_new_from_socket() is |
2506 | no longer supported. udev_monitor_new_from_netlink() needs to be | |
2507 | used to subscribe to events. | |
2508 | ||
194bbe33 KS |
2509 | * udev: when udevd is started by systemd, processes which are left |
2510 | behind by forking them off of udev rules, are unconditionally cleaned | |
2511 | up and killed now after the event handling has finished. Services or | |
2512 | daemons must be started as systemd services. Services can be | |
ea5943d3 | 2513 | pulled-in by udev to get started, but they can no longer be directly |
194bbe33 KS |
2514 | forked by udev rules. |
2515 | ||
f13b388f KS |
2516 | * udev: the daemon binary is called systemd-udevd now and installed |
2517 | in /usr/lib/systemd/. Standalone builds or non-systemd systems need | |
2518 | to adapt to that, create symlink, or rename the binary after building | |
2519 | it. | |
2520 | ||
ea5943d3 | 2521 | * libudev no longer provides these symbols: |
c1959569 KS |
2522 | udev_monitor_from_socket() |
2523 | udev_queue_get_failed_list_entry() | |
2524 | udev_get_{dev,sys,run}_path() | |
ea5943d3 | 2525 | The versions number was bumped and symbol versioning introduced. |
c1959569 | 2526 | |
ea5943d3 | 2527 | * systemd-loginctl and systemd-journalctl have been renamed |
9ae9afce | 2528 | to loginctl and journalctl to match systemctl. |
18b754d3 KS |
2529 | |
2530 | * The config files: /etc/systemd/systemd-logind.conf and | |
2531 | /etc/systemd/systemd-journald.conf have been renamed to | |
2532 | logind.conf and journald.conf. Package updates should rename | |
2533 | the files to the new names on upgrade. | |
2534 | ||
ea5943d3 LP |
2535 | * For almost all files the license is now LGPL2.1+, changed |
2536 | from the previous GPL2.0+. Exceptions are some minor stuff | |
2537 | of udev (which will be changed to LGPL2.1 eventually, too), | |
2538 | and the MIT licensed sd-daemon.[ch] library that is suitable | |
2539 | to be used as drop-in files. | |
2540 | ||
2541 | * systemd and logind now handle system sleep states, in | |
49f43d5f | 2542 | particular suspending and hibernating. |
ea5943d3 LP |
2543 | |
2544 | * logind now implements a sleep/shutdown/idle inhibiting logic | |
2545 | suitable for a variety of uses. Soonishly Lennart will blog | |
2546 | about this in more detail. | |
2547 | ||
2548 | * var-run.mount and var-lock.mount are no longer provided | |
2549 | (which prevously bind mounted these directories to their new | |
2550 | places). Distributions which have not converted these | |
2551 | directories to symlinks should consider stealing these files | |
2552 | from git history and add them downstream. | |
2553 | ||
2554 | * We introduced the Documentation= field for units and added | |
2555 | this to all our shipped units. This is useful to make it | |
3943231c | 2556 | easier to explore the boot and the purpose of the various |
ea5943d3 LP |
2557 | units. |
2558 | ||
2559 | * All smaller setup units (such as | |
2560 | systemd-vconsole-setup.service) now detect properly if they | |
2561 | are run in a container and are skipped when | |
2562 | appropriate. This guarantees an entirely noise-free boot in | |
2563 | Linux container environments such as systemd-nspawn. | |
2564 | ||
2565 | * A framework for implementing offline system updates is now | |
2566 | integrated, for details see: | |
2567 | http://freedesktop.org/wiki/Software/systemd/SystemUpdates | |
2568 | ||
2569 | * A new service type Type=idle is available now which helps us | |
2570 | avoiding ugly interleaving of getty output and boot status | |
2571 | messages. | |
2572 | ||
439d6dfd LP |
2573 | * There's now a system-wide CapabilityBoundingSet= option to |
2574 | globally reduce the set of capabilities for the | |
ea5943d3 LP |
2575 | system. This is useful to drop CAP_SYS_MKNOD, CAP_SYS_RAWIO, |
2576 | CAP_NET_RAW, CAP_SYS_MODULE, CAP_SYS_TIME, CAP_SYS_PTRACE or | |
2577 | even CAP_NET_ADMIN system-wide for secure systems. | |
2578 | ||
2579 | * There are now system-wide DefaultLimitXXX= options to | |
2580 | globally change the defaults of the various resource limits | |
2581 | for all units started by PID 1. | |
2582 | ||
2583 | * Harald Hoyer's systemd test suite has been integrated into | |
2584 | systemd which allows easy testing of systemd builds in qemu | |
2585 | and nspawn. (This is really awesome! Ask us for details!) | |
2586 | ||
3943231c LP |
2587 | * The fstab parser is now implemented as generator, not inside |
2588 | of PID 1 anymore. | |
ea5943d3 LP |
2589 | |
2590 | * systemctl will now warn you if .mount units generated from | |
2591 | /etc/fstab are out of date due to changes in fstab that | |
2592 | haven't been read by systemd yet. | |
2593 | ||
2594 | * systemd is now suitable for usage in initrds. Dracut has | |
2595 | already been updated to make use of this. With this in place | |
2596 | initrds get a slight bit faster but primarily are much | |
2597 | easier to introspect and debug since "systemctl status" in | |
2598 | the host system can be used to introspect initrd services, | |
2599 | and the journal from the initrd is kept around too. | |
2600 | ||
2601 | * systemd-delta has been added, a tool to explore differences | |
2602 | between user/admin configuration and vendor defaults. | |
2603 | ||
2604 | * PrivateTmp= now affects both /tmp and /var/tmp. | |
2605 | ||
2606 | * Boot time status messages are now much prettier and feature | |
2607 | proper english language. Booting up systemd has never been | |
2608 | so sexy. | |
2609 | ||
2610 | * Read-ahead pack files now include the inode number of all | |
2611 | files to pre-cache. When the inode changes the pre-caching | |
2612 | is not attempted. This should be nicer to deal with updated | |
2613 | packages which might result in changes of read-ahead | |
2614 | patterns. | |
2615 | ||
2616 | * We now temporaritly lower the kernel's read_ahead_kb variable | |
2617 | when collecting read-ahead data to ensure the kernel's | |
2618 | built-in read-ahead does not add noise to our measurements | |
2619 | of necessary blocks to pre-cache. | |
2620 | ||
2621 | * There's now RequiresMountsFor= to add automatic dependencies | |
2622 | for all mounts necessary for a specific file system path. | |
2623 | ||
2624 | * MountAuto= and SwapAuto= have been removed from | |
2625 | system.conf. Mounting file systems at boot has to take place | |
2626 | in systemd now. | |
2627 | ||
2628 | * nspawn now learned a new switch --uuid= to set the machine | |
2629 | ID on the command line. | |
2630 | ||
f8c0a2cb | 2631 | * nspawn now learned the -b switch to automatically search |
ea5943d3 LP |
2632 | for an init system. |
2633 | ||
2634 | * vt102 is now the default TERM for serial TTYs, upgraded from | |
2635 | vt100. | |
2636 | ||
2637 | * systemd-logind now works on VT-less systems. | |
2638 | ||
2639 | * The build tree has been reorganized. The individual | |
3943231c | 2640 | components now have directories of their own. |
ea5943d3 LP |
2641 | |
2642 | * A new condition type ConditionPathIsReadWrite= is now available. | |
2643 | ||
2644 | * nspawn learned the new -C switch to create cgroups for the | |
2645 | container in other hierarchies. | |
2646 | ||
2647 | * We now have support for hardware watchdogs, configurable in | |
2648 | system.conf. | |
2649 | ||
2650 | * The scheduled shutdown logic now has a public API. | |
2651 | ||
2652 | * We now mount /tmp as tmpfs by default, but this can be | |
2653 | masked and /etc/fstab can override it. | |
2654 | ||
2655 | * Since udisks doesn't make use of /media anymore we are not | |
2656 | mounting a tmpfs on it anymore. | |
2657 | ||
2658 | * journalctl gained a new --local switch to only interleave | |
2659 | locally generated journal files. | |
2660 | ||
2661 | * We can now load the IMA policy at boot automatically. | |
2662 | ||
2663 | * The GTK tools have been split off into a systemd-ui. | |

16f1239e | 2676 | CHANGES WITH 44: |
b6a86739 | 2677 | |
16f1239e LP |
2678 | * This is mostly a bugfix release |
2679 | ||
2680 | * Support optional initialization of the machine ID from the | |
2681 | KVM or container configured UUID. | |
2682 | ||
2683 | * Support immediate reboots with "systemctl reboot -ff" | |
2684 | ||
2685 | * Show /etc/os-release data in systemd-analyze output | |
2686 | ||
ab06eef8 | 2687 | * Many bugfixes for the journal, including endianness fixes and |
16f1239e LP |
2688 | ensuring that disk space enforcement works |
2689 | ||
2690 | * sd-login.h is C++ comptaible again | |
2691 | ||
2692 | * Extend the /etc/os-release format on request of the Debian | |
2693 | folks | |
2694 | ||
2695 | * We now refuse non-UTF8 strings used in various configuration | |
2696 | and unit files. This is done to ensure we don't pass invalid | |
2697 | data over D-Bus or expose it elsewhere. | |
2698 | ||
2699 | * Register Mimo USB Screens as suitable for automatic seat | |
2700 | configuration | |
2701 | ||
2702 | * Read SELinux client context from journal clients in a race | |
2703 | free fashion | |
2704 | ||
2705 | * Reorder configuration file lookup order. /etc now always | |
2706 | overrides /run in order to allow the administrator to always | |
2707 | and unconditionally override vendor supplied or | |
2708 | automatically generated data. | |
2709 | ||
2710 | * The various user visible bits of the journal now have man | |
2711 | pages. We still lack man pages for the journal API calls | |
2712 | however. | |
2713 | ||
2714 | * We now ship all man pages in HTML format again in the | |
2715 | tarball. | |

2725 | ||
2726 | * systems lacking /etc/os-release are no longer supported. | |
2727 | ||
2728 | * Various functionality updates to libsystemd-login.so | |
2729 | ||
2730 | * Track class of PAM logins to distuingish greeters from | |
2731 | normal user logins. | |

b6a86739 | 2737 | |
204fa33c LP |
2738 | * This is an important bugfix release for v41. |
2739 | ||
2740 | * Building man pages is now optional which should be useful | |
2741 | for those building systemd from git but unwilling to install | |
2742 | xsltproc. | |
2743 | ||
2744 | * Watchdog support for supervising services is now usable. In | |
2745 | a future release support for hardware watchdogs | |
2746 | (i.e. /dev/watchdog) will be added building on this. | |
2747 | ||
2748 | * Service start rate limiting is now configurable and can be | |
2749 | turned off per service. When a start rate limit is hit a | |
2750 | reboot can automatically be triggered. | |
2751 | ||
2752 | * New CanReboot(), CanPowerOff() bus calls in systemd-logind. | |

e0d25329 | 2758 | CHANGES WITH 41: |
b6a86739 | 2759 | |
e0d25329 KS |
2760 | * The systemd binary is installed /usr/lib/systemd/systemd now; |
2761 | An existing /sbin/init symlink needs to be adapted with the | |
2762 | package update. | |
2763 | ||
b13df964 LP |
2764 | * The code that loads kernel modules has been ported to invoke |
2765 | libkmod directly, instead of modprobe. This means we do not | |
2766 | support systems with module-init-tools anymore. | |
2767 | ||
2768 | * Watchdog support is now already useful, but still not | |
2769 | complete. | |
2770 | ||
2771 | * A new kernel command line option systemd.setenv= is | |
2772 | understood to set system wide environment variables | |
2773 | dynamically at boot. | |
2774 | ||
e9c1ea9d | 2775 | * We now limit the set of capabilities of systemd-journald. |
ccd07a08 | 2776 | |
353e12c2 LP |
2777 | * We now set SIGPIPE to ignore by default, since it only is |
2778 | useful in shell pipelines, and has little use in general | |
2779 | code. This can be disabled with IgnoreSIPIPE=no in unit | |
2780 | files. | |

b6a86739 | 2787 | |
d26e4270 LP |
2788 | * This is mostly a bugfix release |
2789 | ||
2790 | * We now expose the reason why a service failed in the | |
2791 | "Result" D-Bus property. | |
2792 | ||
2793 | * Rudimentary service watchdog support (will be completed over | |
2794 | the next few releases.) | |
2795 | ||
2796 | * When systemd forks off in order execute some service we will | |
2797 | now immediately changes its argv[0] to reflect which process | |
2798 | it will execute. This is useful to minimize the time window | |
2799 | with a generic argv[0], which makes bootcharts more useful | |

220a21d3 | 2805 | CHANGES WITH 39: |
b6a86739 | 2806 | |
220a21d3 LP |
2807 | * This is mostly a test release, but incorporates many |
2808 | bugfixes. | |
2809 | ||
2810 | * New systemd-cgtop tool to show control groups by their | |
2811 | resource usage. | |
2812 | ||
2813 | * Linking against libacl for ACLs is optional again. If | |
2814 | disabled, support tracking device access for active logins | |
2815 | goes becomes unavailable, and so does access to the user | |
2816 | journals by the respective users. | |
2817 | ||
2818 | * If a group "adm" exists, journal files are automatically | |
2819 | owned by them, thus allow members of this group full access | |
2820 | to the system journal as well as all user journals. | |
2821 | ||
2822 | * The journal now stores the SELinux context of the logging | |
2823 | client for all entries. | |
2824 | ||
2825 | * Add C++ inclusion guards to all public headers | |
2826 | ||
2827 | * New output mode "cat" in the journal to print only text | |
2828 | messages, without any meta data like date or time. | |
2829 | ||
2830 | * Include tiny X server wrapper as a temporary stop-gap to | |
2831 | teach XOrg udev display enumeration. This is used by display | |
2832 | managers such as gdm, and will go away as soon as XOrg | |
2833 | learned native udev hotplugging for display devices. | |
2834 | ||
2835 | * Add new systemd-cat tool for executing arbitrary programs | |
2836 | with STDERR/STDOUT connected to the journal. Can also act as | |
2837 | BSD logger replacement, and does so by default. | |
2838 | ||
2839 | * Optionally store all locally generated coredumps in the | |
2840 | journal along with meta data. | |
2841 | ||
2842 | * systemd-tmpfiles learnt four new commands: n, L, c, b, for | |
2843 | writing short strings to files (for usage for /sys), and for | |
2844 | creating symlinks, character and block device nodes. | |
2845 | ||
2846 | * New unit file option ControlGroupPersistent= to make cgroups | |
2847 | persistent, following the mechanisms outlined in | |
2848 | http://www.freedesktop.org/wiki/Software/systemd/PaxControlGroups | |
2849 | ||
2850 | * Support multiple local RTCs in a sane way | |
2851 | ||
2852 | * No longer monopolize IO when replaying readahead data on | |
2853 | rotating disks, since we might starve non-file-system IO to | |
2854 | death, since fanotify() will not see accesses done by blkid, | |

2863 | CHANGES WITH 38: | |
b6a86739 | 2864 | |
220a21d3 LP |
2865 | * This is mostly a test release, but incorporates many |
2866 | bugfixes. | |
2867 | ||
2868 | * The git repository moved to: | |
2869 | git://anongit.freedesktop.org/systemd/systemd | |
2870 | ssh://git.freedesktop.org/git/systemd/systemd | |
2871 | ||
2872 | * First release with the journal | |
2873 | http://0pointer.de/blog/projects/the-journal.html | |
2874 | ||
2875 | * The journal replaces both systemd-kmsg-syslogd and | |
2876 | systemd-stdout-bridge. | |
2877 | ||
2878 | * New sd_pid_get_unit() API call in libsystemd-logind | |
2879 | ||
2880 | * Many systemadm clean-ups | |
2881 | ||
2882 | * Introduce remote-fs-pre.target which is ordered before all | |
2883 | remote mounts and may be used to start services before all | |
2884 | remote mounts. | |
2885 | ||
2886 | * Added Mageia support | |
2887 | ||
2888 | * Add bash completion for systemd-loginctl | |
2889 | ||
2890 | * Actively monitor PID file creation for daemons which exit in | |
2891 | the parent process before having finished writing the PID | |
2892 | file in the daemon process. Daemons which do this need to be | |
2893 | fixed (i.e. PID file creation must have finished before the | |
2894 | parent exits), but we now react a bit more gracefully to them. | |
2895 | ||
2896 | * Add colourful boot output, mimicking the well-known output | |
2897 | of existing distributions. | |
2898 | ||
2899 | * New option PassCredentials= for socket units, for | |
2900 | compatibility with a recent kernel ABI breakage. | |
2901 | ||
2902 | * /etc/rc.local is now hooked in via a generator binary, and | |
2903 | thus will no longer act as synchronization point during | |
2904 | boot. | |
2905 | ||
2906 | * systemctl list-unit-files now supports --root=. | |
2907 | ||
2908 | * systemd-tmpfiles now understands two new commands: z, Z for | |
2909 | relabelling files according to the SELinux database. This is | |
2910 | useful to apply SELinux labels to specific files in /sys, | |
2911 | among other things. | |
2912 | ||
2913 | * Output of SysV services is now forwarded to both the console | |
2914 | and the journal by default, not only just the console. | |
2915 | ||
2916 | * New man pages for all APIs from libsystemd-login. | |
2917 | ||
2918 | * The build tree got reorganized and a the build system is a | |
2919 | lot more modular allowing embedded setups to specifically | |
2920 | select the components of systemd they are interested in. | |
2921 | ||
2922 | * Support for Linux systems lacking the kernel VT subsystem is | |
2923 | restored. | |
2924 | ||
2925 | * configure's --with-rootdir= got renamed to | |
2926 | --with-rootprefix= to follow the naming used by udev and | |
2927 | kmod | |
2928 | ||
2929 | * Unless specified otherwise we'll now install to /usr instead | |
2930 | of /usr/local by default. | |
2931 | ||
2932 | * Processes with '@' in argv[0][0] are now excluded from the | |
2933 | final shut-down killing spree, following the logic explained | |
2934 | in: | |
2935 | http://www.freedesktop.org/wiki/Software/systemd/RootStorageDaemons | |
2936 | ||
2937 | * All processes remaining in a service cgroup when we enter | |
2938 | the START or START_PRE states are now killed with | |
2939 | SIGKILL. That means it is no longer possible to spawn | |
2940 | background processes from ExecStart= lines (which was never | |
2941 | supported anyway, and bad style). | |
2942 | ||
2943 | * New PropagateReloadTo=/PropagateReloadFrom= options to bind | |
2944 | reloading of units together. | |
