3CHANGES WITH 188:
4
5 * When running in --user mode systemd will now become a
6 subreaper (PR_SET_CHILD_SUBREAPER). This should make the ps
7 tree a lot more organized.
8
9 * A new PartOf= unit dependency type has been introduced that
10 may be used to group services in a natural way.
11
12 * "systemctl enable" may now be used to enable instances of
13 services.
14
15 * journalctl now prints error log levels in red, and
16 warning/notice log levels in bright white. It also supports
17 filtering by log level now.
18
19 * cgtop gained a new -n switch (similar to top), to configure
20 the maximum number of iterations to run for. It also gained
21 -b, to run in batch mode (accepting no input).
22
23 * The suffix ".service" may now be ommited on most systemctl
24 command lines involving service unit names.
25
26 * There's a new bus call in logind to lock all sessions, as
27 well as a loginctl verb for it "lock-sessions".
28
29 * libsystemd-logind.so gained a new call sd_journal_perror()
30 that works similar to libc perror() but logs to the journal
31 and encodes structured information about the error number.
32
33 * /etc/crypttab entries now understand the new keyfile-size=
34 option.
35
36 * shutdown(8) now can send a (configurable) wall message when
37 a shutdown is cancelled.
38
39 * The mount propagation mode for the root file system will now
40 default to "shared", which is useful to make containers work
41 nicely out-of-the-box so that they receive new mounts from
42 the host. This can be undone locally by running "mount
43 --make-rprivate /" if needed.
44
45 * The prefdm.service file has been removed. Distributions
46 should maintain this unit downstream if they intend to keep
47 it around. However, we recommend writing normal unit files
48 for display managers instead.
49
50 * Since systemd is a crucial part of the OS we will now
51 default to a number of compiler switches that improve
52 security (hardening) such as read-only relocations, stack
53 protection, and suchlike.
54
55 * The TimeoutSec= setting for services is now split into
56 TimeoutStartSec= and TimeoutStopSec= to allow configuration
57 of individual time outs for the start and the stop phase of
58 the service.

LP
67CHANGES WITH 187:
68
69 * The journal and id128 C APIs are now fully documented as man
70 pages.
71
72 * Extra safety checks have been added when transitioning from
73 the initial RAM disk to the main system to avoid accidental
74 data loss.
75
c269cec3 76 * /etc/crypttab entries now understand the new keyfile-offset=
c4f1b862
LP
77 option.
78
79 * systemctl -t can now be used to filter by unit load state.
80
81 * The journal C API gained the new sd_journal_wait() call to
82 make writing synchronous journal clients easier.
83
84 * journalctl gained the new -D switch to show journals from a
85 specific directory.
86
87 * journalctl now displays a special marker between log
88 messages of two different boots.
89
90 * The journal is now explicitly flushed to /var via a service
91 systemd-journal-flush.service, rather than implicitly simply
92 by seeing /var/log/journal to be writable.
93
94 * journalctl (and the journal C APIs) can now match for much
95 more complex expressions, with alternatives and
96 disjunctions.
97
98 * When transitioning from the initial RAM disk to the main
99 system we will now kill all processes in a killing spree to
100 ensure no processes stay around by accident.
101
102 * Three new specifiers may be used in unit files: %u, %h, %s
103 resolve to the user name, user home directory resp. user
104 shell. This is useful for running systemd user instances.
105
106 * We now automatically rotate journal files if their data
107 object hash table gets a fill level > 75%. We also size the
108 hash table based on the configured maximum file size. This
109 together should lower hash collisions drastically and thus
110 speed things up a bit.
111
112 * journalctl gained the new "--header" switch to introspect
113 header data of journal files.
114
115 * A new setting SystemCallFilters= has been added to services
116 which may be used to apply blacklists or whitelists to
117 system calls. This is based on SECCOMP Mode 2 of Linux 3.5.
118
119 * nspawn gained a new --link-journal= switch (and quicker: -j)
120 to link the container journal with the host. This makes it
121 very easy to centralize log viewing on the host for all
122 guests while still keeping the journal files separated.
123
124 * Many bugfixes and optimizations

b5b4c94a
LP
131CHANGES WITH 186:
132
133 * Several tools now understand kernel command line arguments,
134 which are only read when run in an initial RAM disk. They
135 usually follow closely their normal counterparts, but are
136 prefixed with rd.
137
138 * There's a new tool to analyze the readahead files that are
139 automatically generated at boot. Use:
140
141 /usr/lib/systemd/systemd-readahead analyze /.readahead
142
143 * We now provide an early debug shell on tty9 if this enabled. Use:
144
d1f9edaf 145 systemctl enable debug-shell.service
b5b4c94a
LP
146
147 * All plymouth related units have been moved into the Plymouth
148 package. Please make sure to upgrade your Plymouth version
149 as well.
150
151 * systemd-tmpfiles now supports getting passed the basename of
152 a configuration file only, in which case it will look for it
153 in all appropriate directories automatically.
154
155 * udevadm info now takes a /dev or /sys path as argument, and
156 does the right thing. Example:
157
158 udevadm info /dev/sda
159 udevadm info /sys/class/block/sda
160
161 * systemctl now prints a warning if a unit is stopped but a
162 unit that might trigger it continues to run. Example: a
163 service is stopped but the socket that activates it is left
164 running.
165
166 * "systemctl status" will now mention if the log output was
167 shortened due to rotation since a service has been started.
168
169 * The journal API now exposes functions to determine the
170 "cutoff" times due to rotation.
171
172 * journald now understands SIGUSR1 and SIGUSR2 for triggering
173 immediately flushing of runtime logs to /var if possible,
174 resp. for triggering immediate rotation of the journal
175 files.
176
177 * It is now considered an error if a service is attempted to
178 be stopped that is not loaded.
179
180 * XDG_RUNTIME_DIR now uses numeric UIDs instead of usernames.
181
182 * systemd-analyze now supports Python 3
183
184 * tmpfiles now supports cleaning up directories via aging
185 where the first level dirs are always kept around but
186 directories beneath it automatically aged. This is enabled
187 by prefixing the age field with '~'.
188
189 * Seat objects now expose CanGraphical, CanTTY properties
190 which is required to deal with very fast bootups where the
191 display manager might be running before the graphics drivers
192 completed initialization.
193
194 * Seat objects now expose a State property.
195
196 * We now include RPM macros for service enabling/disabling
197 based on the preset logic. We recommend RPM based
198 distributions to make use of these macros if possible. This
199 makes it simpler to reuse RPM spec files across
200 distributions.
201
202 * We now make sure that the collected systemd unit name is
203 always valid when services log to the journal via
204 STDOUT/STDERR.
205
206 * There's a new man page kernel-command-line(7) detailing all
207 command line options we understand.
208
209 * The fstab generator may now be disabled at boot by passing
210 fstab=0 on the kernel command line.
211
91ac7425 212 * A new kernel command line option modules-load= is now understood
b5b4c94a
LP
213 to load a specific kernel module statically, early at boot.
214
215 * Unit names specified on the systemctl command line are now
216 automatically escaped as needed. Also, if file system or
217 device paths are specified they are automatically turned
218 into the appropriate mount or device unit names. Example:
219
220 systemctl status /home
221 systemctl status /dev/sda
222
223 * The SysVConsole= configuration option has been removed from
224 system.conf parsing.
225
226 * The SysV search path is no longer exported on the D-Bus
227 Manager object.
228
229 * The Names= option is been removed from unit file parsing.
230
231 * There's a new man page bootup(7) detailing the boot process.
232
233 * Every unit and every generator we ship with systemd now
234 comes with full documentation. The self-explanatory boot is
235 complete.
236
237 * A couple of services gained "systemd-" prefixes in their
238 name if they wrap systemd code, rather than only external
239 code. Among them fsck@.service which is now
240 systemd-fsck@.service.
241
242 * The HaveWatchdog property has been removed from the D-Bus
243 Manager object.
244
245 * systemd.confirm_spawn= on the kernel command line should now
246 work sensibly.
247
248 * There's a new man page crypttab(5) which details all options
249 we actually understand.
250
251 * systemd-nspawn gained a new --capability= switch to pass
252 additional capabilities to the container.
253
254 * timedated will now read known NTP implementation unit names
5b00c016 255 from /usr/lib/systemd/ntp-units.d/*.list,
b5b4c94a
LP
256 systemd-timedated-ntp.target has been removed.
257
258 * journalctl gained a new switch "-b" that lists log data of
259 the current boot only.
260
261 * The notify socket is in the abstract namespace again, in
262 order to support daemons which chroot() at start-up.
263
264 * There is a new Storage= configuration option for journald
265 which allows configuration of where log data should go. This
266 also provides a way to disable journal logging entirely, so
267 that data collected is only forwarded to the console, the
268 kernel log buffer or another syslog implementation.
269
c4f1b862 270 * Many bugfixes and optimizations

2d197285
KS
277CHANGES WITH 185:
278 * "systemctl help <unit>" now shows the man page if one is
279 available.
280
281 * Several new man pages have been added.
282
b5b4c94a
LP
283 * MaxLevelStore=, MaxLevelSyslog=, MaxLevelKMsg=,
284 MaxLevelConsole= can now be specified in
285 journald.conf. These options allow reducing the amount of
286 data stored on disk or forwarded by the log level.
2d197285 287
b5b4c94a
LP
288 * TimerSlackNSec= can now be specified in system.conf for
289 PID1. This allows system-wide power savings.

LP
295CHANGES WITH 184:
296 * logind is now capable of (optionally) handling power and
297 sleep keys as well as the lid switch.
298
299 * journalctl now understands the syntax "journalctl
300 /usr/bin/avahi-daemon" to get all log output of a specific
301 daemon.
302
303 * CapabilityBoundingSet= in system.conf now also influences
304 the capability bound set of usermode helpers of the kernel.

310
ea5943d3 311CHANGES WITH 183:
187076d4
LP
312 * Note that we skipped 139 releases here in order to set the
313 new version to something that is greater than both udev's
314 and systemd's most recent version number.
315
194bbe33
KS
316 * udev: all udev sources are merged into the systemd source tree now.
317 All future udev development will happen in the systemd tree. It
318 is still fully supported to use the udev daemon and tools without
319 systemd running, like in initramfs or other init systems. Building
320 udev though, will require the *build* of the systemd tree, but
ea5943d3 321 udev can be properly *run* without systemd.
07cd4fc1 322
91cf7e5c 323 * udev: /lib/udev/devices/ are not read anymore; systemd-tmpfiles
f13b388f
KS
324 should be used to create dead device nodes as workarounds for broken
325 subsystems.
64661ee7 326
2d13da88
KS
327 * udev: RUN+="socket:..." and udev_monitor_new_from_socket() is
328 no longer supported. udev_monitor_new_from_netlink() needs to be
329 used to subscribe to events.
330
194bbe33
KS
331 * udev: when udevd is started by systemd, processes which are left
332 behind by forking them off of udev rules, are unconditionally cleaned
333 up and killed now after the event handling has finished. Services or
334 daemons must be started as systemd services. Services can be
ea5943d3 335 pulled-in by udev to get started, but they can no longer be directly
194bbe33
KS
336 forked by udev rules.
337
f13b388f
KS
338 * udev: the daemon binary is called systemd-udevd now and installed
339 in /usr/lib/systemd/. Standalone builds or non-systemd systems need
340 to adapt to that, create symlink, or rename the binary after building
341 it.
342
ea5943d3 343 * libudev no longer provides these symbols:
c1959569
KS
344 udev_monitor_from_socket()
345 udev_queue_get_failed_list_entry()
346 udev_get_{dev,sys,run}_path()
ea5943d3 347 The versions number was bumped and symbol versioning introduced.
c1959569 348
ea5943d3 349 * systemd-loginctl and systemd-journalctl have been renamed
9ae9afce 350 to loginctl and journalctl to match systemctl.
18b754d3
KS
351
352 * The config files: /etc/systemd/systemd-logind.conf and
353 /etc/systemd/systemd-journald.conf have been renamed to
354 logind.conf and journald.conf. Package updates should rename
355 the files to the new names on upgrade.
356
ea5943d3
LP
357 * For almost all files the license is now LGPL2.1+, changed
358 from the previous GPL2.0+. Exceptions are some minor stuff
359 of udev (which will be changed to LGPL2.1 eventually, too),
360 and the MIT licensed sd-daemon.[ch] library that is suitable
361 to be used as drop-in files.
362
363 * systemd and logind now handle system sleep states, in
49f43d5f 364 particular suspending and hibernating.
ea5943d3
LP
365
366 * logind now implements a sleep/shutdown/idle inhibiting logic
367 suitable for a variety of uses. Soonishly Lennart will blog
368 about this in more detail.
369
370 * var-run.mount and var-lock.mount are no longer provided
371 (which prevously bind mounted these directories to their new
372 places). Distributions which have not converted these
373 directories to symlinks should consider stealing these files
374 from git history and add them downstream.
375
376 * We introduced the Documentation= field for units and added
377 this to all our shipped units. This is useful to make it
3943231c 378 easier to explore the boot and the purpose of the various
ea5943d3
LP
379 units.
380
381 * All smaller setup units (such as
382 systemd-vconsole-setup.service) now detect properly if they
383 are run in a container and are skipped when
384 appropriate. This guarantees an entirely noise-free boot in
385 Linux container environments such as systemd-nspawn.
386
387 * A framework for implementing offline system updates is now
388 integrated, for details see:
389 http://freedesktop.org/wiki/Software/systemd/SystemUpdates
390
391 * A new service type Type=idle is available now which helps us
392 avoiding ugly interleaving of getty output and boot status
393 messages.
394
439d6dfd
LP
395 * There's now a system-wide CapabilityBoundingSet= option to
396 globally reduce the set of capabilities for the
ea5943d3
LP
397 system. This is useful to drop CAP_SYS_MKNOD, CAP_SYS_RAWIO,
398 CAP_NET_RAW, CAP_SYS_MODULE, CAP_SYS_TIME, CAP_SYS_PTRACE or
399 even CAP_NET_ADMIN system-wide for secure systems.
400
401 * There are now system-wide DefaultLimitXXX= options to
402 globally change the defaults of the various resource limits
403 for all units started by PID 1.
404
405 * Harald Hoyer's systemd test suite has been integrated into
406 systemd which allows easy testing of systemd builds in qemu
407 and nspawn. (This is really awesome! Ask us for details!)
408
3943231c
LP
409 * The fstab parser is now implemented as generator, not inside
410 of PID 1 anymore.
ea5943d3
LP
411
412 * systemctl will now warn you if .mount units generated from
413 /etc/fstab are out of date due to changes in fstab that
414 haven't been read by systemd yet.
415
416 * systemd is now suitable for usage in initrds. Dracut has
417 already been updated to make use of this. With this in place
418 initrds get a slight bit faster but primarily are much
419 easier to introspect and debug since "systemctl status" in
420 the host system can be used to introspect initrd services,
421 and the journal from the initrd is kept around too.
422
423 * systemd-delta has been added, a tool to explore differences
424 between user/admin configuration and vendor defaults.
425
426 * PrivateTmp= now affects both /tmp and /var/tmp.
427
428 * Boot time status messages are now much prettier and feature
429 proper english language. Booting up systemd has never been
430 so sexy.
431
432 * Read-ahead pack files now include the inode number of all
433 files to pre-cache. When the inode changes the pre-caching
434 is not attempted. This should be nicer to deal with updated
435 packages which might result in changes of read-ahead
436 patterns.
437
438 * We now temporaritly lower the kernel's read_ahead_kb variable
439 when collecting read-ahead data to ensure the kernel's
440 built-in read-ahead does not add noise to our measurements
441 of necessary blocks to pre-cache.
442
443 * There's now RequiresMountsFor= to add automatic dependencies
444 for all mounts necessary for a specific file system path.
445
446 * MountAuto= and SwapAuto= have been removed from
447 system.conf. Mounting file systems at boot has to take place
448 in systemd now.
449
450 * nspawn now learned a new switch --uuid= to set the machine
451 ID on the command line.
452
f8c0a2cb 453 * nspawn now learned the -b switch to automatically search
ea5943d3
LP
454 for an init system.
455
456 * vt102 is now the default TERM for serial TTYs, upgraded from
457 vt100.
458
459 * systemd-logind now works on VT-less systems.
460
461 * The build tree has been reorganized. The individual
3943231c 462 components now have directories of their own.
ea5943d3
LP
463
464 * A new condition type ConditionPathIsReadWrite= is now available.
465
466 * nspawn learned the new -C switch to create cgroups for the
467 container in other hierarchies.
468
469 * We now have support for hardware watchdogs, configurable in
470 system.conf.
471
472 * The scheduled shutdown logic now has a public API.
473
474 * We now mount /tmp as tmpfs by default, but this can be
475 masked and /etc/fstab can override it.
476
477 * Since udisks doesn't make use of /media anymore we are not
478 mounting a tmpfs on it anymore.
479
480 * journalctl gained a new --local switch to only interleave
481 locally generated journal files.
482
483 * We can now load the IMA policy at boot automatically.
484
485 * The GTK tools have been split off into a systemd-ui.

498CHANGES WITH 44:
499 * This is mostly a bugfix release
500
501 * Support optional initialization of the machine ID from the
502 KVM or container configured UUID.
503
504 * Support immediate reboots with "systemctl reboot -ff"
505
506 * Show /etc/os-release data in systemd-analyze output
507
508 * Many bugfixes for the journal, including endianess fixes and
509 ensuring that disk space enforcement works
510
511 * sd-login.h is C++ comptaible again
512
513 * Extend the /etc/os-release format on request of the Debian
514 folks
515
516 * We now refuse non-UTF8 strings used in various configuration
517 and unit files. This is done to ensure we don't pass invalid
518 data over D-Bus or expose it elsewhere.
519
520 * Register Mimo USB Screens as suitable for automatic seat
521 configuration
522
523 * Read SELinux client context from journal clients in a race
524 free fashion
525
526 * Reorder configuration file lookup order. /etc now always
527 overrides /run in order to allow the administrator to always
528 and unconditionally override vendor supplied or
529 automatically generated data.
530
531 * The various user visible bits of the journal now have man
532 pages. We still lack man pages for the journal API calls
533 however.
534
535 * We now ship all man pages in HTML format again in the

544 * This is mostly a bugfix release
545
546 * systems lacking /etc/os-release are no longer supported.
547
548 * Various functionality updates to libsystemd-login.so
549
550 * Track class of PAM logins to distuingish greeters from

556CHANGES WITH 42:
557 * This is an important bugfix release for v41.
558
559 * Building man pages is now optional which should be useful
560 for those building systemd from git but unwilling to install
561 xsltproc.
562
563 * Watchdog support for supervising services is now usable. In
564 a future release support for hardware watchdogs
565 (i.e. /dev/watchdog) will be added building on this.
566
567 * Service start rate limiting is now configurable and can be
568 turned off per service. When a start rate limit is hit a
569 reboot can automatically be triggered.
570
571 * New CanReboot(), CanPowerOff() bus calls in systemd-logind.

577CHANGES WITH 41:
578 * The systemd binary is installed /usr/lib/systemd/systemd now;
579 An existing /sbin/init symlink needs to be adapted with the
580 package update.
581

582 * The code that loads kernel modules has been ported to invoke
583 libkmod directly, instead of modprobe. This means we do not
584 support systems with module-init-tools anymore.
585
586 * Watchdog support is now already useful, but still not
587 complete.
588
589 * A new kernel command line option systemd.setenv= is
590 understood to set system wide environment variables
591 dynamically at boot.
592

LP
593 * We now limit the set of capabilities of systemd-journald.
594

595 * We now set SIGPIPE to ignore by default, since it only is
596 useful in shell pipelines, and has little use in general
597 code. This can be disabled with IgnoreSIPIPE=no in unit
598 files.

604CHANGES WITH 40:
605 * This is mostly a bugfix release
606
607 * We now expose the reason why a service failed in the
608 "Result" D-Bus property.
609
610 * Rudimentary service watchdog support (will be completed over
611 the next few releases.)
612
613 * When systemd forks off in order execute some service we will
614 now immediately changes its argv[0] to reflect which process
615 it will execute. This is useful to minimize the time window
616 with a generic argv[0], which makes bootcharts more useful

622CHANGES WITH 39:
623 * This is mostly a test release, but incorporates many
624 bugfixes.
625
626 * New systemd-cgtop tool to show control groups by their
627 resource usage.
628
629 * Linking against libacl for ACLs is optional again. If
630 disabled, support tracking device access for active logins
631 goes becomes unavailable, and so does access to the user
632 journals by the respective users.
633
634 * If a group "adm" exists, journal files are automatically
635 owned by them, thus allow members of this group full access
636 to the system journal as well as all user journals.
637
638 * The journal now stores the SELinux context of the logging
639 client for all entries.
640
641 * Add C++ inclusion guards to all public headers
642
643 * New output mode "cat" in the journal to print only text
644 messages, without any meta data like date or time.
645
646 * Include tiny X server wrapper as a temporary stop-gap to
647 teach XOrg udev display enumeration. This is used by display
648 managers such as gdm, and will go away as soon as XOrg
649 learned native udev hotplugging for display devices.
650
651 * Add new systemd-cat tool for executing arbitrary programs
652 with STDERR/STDOUT connected to the journal. Can also act as
653 BSD logger replacement, and does so by default.
654
655 * Optionally store all locally generated coredumps in the
656 journal along with meta data.
657
658 * systemd-tmpfiles learnt four new commands: n, L, c, b, for
659 writing short strings to files (for usage for /sys), and for
660 creating symlinks, character and block device nodes.
661
662 * New unit file option ControlGroupPersistent= to make cgroups
663 persistent, following the mechanisms outlined in
664 http://www.freedesktop.org/wiki/Software/systemd/PaxControlGroups
665
666 * Support multiple local RTCs in a sane way
667
668 * No longer monopolize IO when replaying readahead data on
669 rotating disks, since we might starve non-file-system IO to
670 death, since fanotify() will not see accesses done by blkid,
671 or fsck.
672
673 * Don't show kernel threads in systemd-cgls anymore, unless
674 requested with new -k switch.

679CHANGES WITH 38:
680 * This is mostly a test release, but incorporates many
681 bugfixes.
682
683 * The git repository moved to:
684 git://anongit.freedesktop.org/systemd/systemd
685 ssh://git.freedesktop.org/git/systemd/systemd
686
687 * First release with the journal
688 http://0pointer.de/blog/projects/the-journal.html
689
690 * The journal replaces both systemd-kmsg-syslogd and
691 systemd-stdout-bridge.
692
693 * New sd_pid_get_unit() API call in libsystemd-logind
694
695 * Many systemadm clean-ups
696
697 * Introduce remote-fs-pre.target which is ordered before all
698 remote mounts and may be used to start services before all
699 remote mounts.
700
701 * Added Mageia support
702
703 * Add bash completion for systemd-loginctl
704
705 * Actively monitor PID file creation for daemons which exit in
706 the parent process before having finished writing the PID
707 file in the daemon process. Daemons which do this need to be
708 fixed (i.e. PID file creation must have finished before the
709 parent exits), but we now react a bit more gracefully to them.
710
711 * Add colourful boot output, mimicking the well-known output
712 of existing distributions.
713
714 * New option PassCredentials= for socket units, for
715 compatibility with a recent kernel ABI breakage.
716
717 * /etc/rc.local is now hooked in via a generator binary, and
718 thus will no longer act as synchronization point during
719 boot.
720
721 * systemctl list-unit-files now supports --root=.
722
723 * systemd-tmpfiles now understands two new commands: z, Z for
724 relabelling files according to the SELinux database. This is
725 useful to apply SELinux labels to specific files in /sys,
726 among other things.
727
728 * Output of SysV services is now forwarded to both the console
729 and the journal by default, not only just the console.
730
731 * New man pages for all APIs from libsystemd-login.
732
733 * The build tree got reorganized and a the build system is a
734 lot more modular allowing embedded setups to specifically
735 select the components of systemd they are interested in.
736
737 * Support for Linux systems lacking the kernel VT subsystem is
738 restored.
739
740 * configure's --with-rootdir= got renamed to
741 --with-rootprefix= to follow the naming used by udev and
742 kmod
743
744 * Unless specified otherwise we'll now install to /usr instead
745 of /usr/local by default.
746
747 * Processes with '@' in argv[0][0] are now excluded from the
748 final shut-down killing spree, following the logic explained
749 in:
750 http://www.freedesktop.org/wiki/Software/systemd/RootStorageDaemons
751
752 * All processes remaining in a service cgroup when we enter
753 the START or START_PRE states are now killed with
754 SIGKILL. That means it is no longer possible to spawn
755 background processes from ExecStart= lines (which was never
756 supported anyway, and bad style).
757
758 * New PropagateReloadTo=/PropagateReloadFrom= options to bind
759 reloading of units together.
