3 | CHANGES 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. | |

c4f1b862 LP |
67 | CHANGES 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 | |
125 | ||

131 | CHANGES 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 |

277 | CHANGES 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 |

4c8cd173 LP |
295 | CHANGES 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. | |

ea5943d3 | 311 | CHANGES 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 |

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. | |

498 | CHANGES 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 | |
536 | tarball. | |

543 | CHANGES WITH 43: |
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 | |
551 | normal user logins. | |

556 | CHANGES 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. | |

577 | CHANGES 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 | ||
b13df964 LP |
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 | ||
ccd07a08 LP |
593 | * We now limit the set of capabilities of systemd-journald. |
594 | ||
353e12c2 LP |
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. | |

604 | CHANGES 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 | |

622 | CHANGES 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. | |

679 | CHANGES 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. | |
