3 | CHANGES WITH 196: |
4 | ||
5 | * udev gained support for loading additional device properties | |
6 | from an indexed database that is keyed by vendor/product IDs | |
7 | and similar device identifiers. For the beginning this | |
8 | "hwdb" is populated with data from the well-known PCI and | |
9 | USB database, but also includes PNP, ACPI and OID data. In | |
10 | the longer run this indexed database shall grow into | |
11 | becoming the one central database for non-essential | |
12 | userspace device metadata. Previously, data from the PCI/USB | |
13 | database was only attached to the select devices, since the | |
14 | lookup was a relatively expensive operation due to O(n) time | |
15 | complexity. Since this is now O(log(n)), we decided to add | |
16 | in this data for all devices where this is available, by | |
17 | default. Note that the indexed database needs to be rebuilt | |
18 | when new data files are installed. To achieve this you need | |
19 | to update your packaging scripts to invoke "udevadm hwdb | |
20 | --update" after installation of hwdb data files. For | |
21 | RPM-based distributions we introduced the new | |
22 | %udev_hwdb_update macro for this purpose. | |
23 | ||
24 | * The Journal gained support for the "Message Catalog", an | |
25 | indexed database to link up additional information with | |
26 | journal entries. For further details please check: | |
27 | ||
28 | http://www.freedesktop.org/wiki/Software/systemd/catalog | |
29 | ||
30 | The indexed message catalog database also needs to be | |
31 | rebuilt after installation of message catalog files. Use | |
32 | "journalctl --update-catalog" for this. For RPM-based | |
33 | distributions we introduced the %journal_catalog_update | |
34 | macro for this purpose. | |
35 | ||
36 | * The Python Journal bindings gained support for the standard | |
37 | Python logging framework. | |
38 | ||
39 | * The Journal API gained new functions for checking whether | |
40 | the underlying file system of a journal file is capable of | |
41 | properly reporting file change notifications, or whether | |
42 | applications that want to reflect journal changes "live" | |
43 | need to recheck journal files continously in appropriate | |
44 | time intervals. | |
45 | ||
46 | * It is now possible to set the "age" field for tmpfiles | |
47 | entries to 0, indicating that files matching this entry | |
48 | shall always be removed when the directories are cleaned up. | |
49 | ||
50 | * coredumpctl gained a new "gdb" verb which invokes gdb | |
51 | right-away on the selected coredump. | |
52 | ||
53 | * There's now support for "hybrid sleep" on kernels that | |
54 | support this, in addition to "suspend" and "hibernate". Use | |
55 | "systemctl hybrid-sleep" to make use of this. | |
56 | ||
57 | * logind's HandleSuspendKey= setting (and related settings) | |
58 | now gained support for a new "lock" setting to simply | |
59 | request the screen lock on all local sessions, instead of | |
60 | actually executing a suspend or hibernation. | |
61 | ||
62 | * systemd will now mount the EFI variables file system by | |
63 | default. | |
64 | ||
65 | * Socket units now gained support for configuration of the | |
66 | SMACK security label. | |
67 | ||
68 | * timedatectl will now output the time of the last and next | |
69 | daylight saving change. | |
70 | ||
71 | * We dropped support for various legacy and distro-specific | |
72 | concepts, such as insserv, early-boot SysV services | |
73 | (i.e. those for non-standard runlevels such as 'b' or 'S') | |
74 | or ArchLinux /etc/rc.conf support. We recommend the | |
75 | distributions who still need support this to either continue | |
76 | to maintain the necessary patches downstream, or find a | |
77 | different solution. (Talk to us if you have questions!) | |
78 | ||
79 | * Various systemd components will now bypass PolicyKit checks | |
80 | for root and otherwise handle properly if PolicyKit is not | |
81 | found to be around. This should fix most issues for | |
82 | PolicyKit-less systems. Quite frankly this should have been | |
83 | this way since day one. It is absolutely our intention to | |
84 | make systemd work fine on PolicyKit-less systems, and we | |
85 | consider it a bug if something doesn't work as it should if | |
86 | PolicyKit is not around. | |
87 | ||
88 | * For embedded systems it is now possible to build udev and | |
89 | systemd without blkid and/or kmod support. | |
90 | ||
91 | * "systemctl switch-root" is now capable of switching root | |
92 | more than once. I.e. in addition to transitions from the | |
93 | initrd to the host OS it is now possible to transition to | |
94 | further OS images from the host. This is useful to implement | |
95 | offline updating tools. | |
96 | ||
97 | * Various other additions have been made to the RPM macros | |
98 | shipped with systemd. Use %udev_rules_update() after | |
99 | installing new udev rules files. %_udevhwdbdir, | |
100 | %_udevrulesdir, %_journalcatalogdir, %_tmpfilesdir, | |
101 | %_sysctldir are now available which resolve to the right | |
102 | directories for packages to place various data files in. | |
103 | ||
104 | * journalctl gained the new --full switch (in addition to | |
105 | --all, to disable ellipsation for long messages. | |

117 | CHANGES WITH 195: |
118 | ||
6827101a | 119 | * journalctl gained new --since= and --until= switches to |
139ee8cc LP |
120 | filter by time. It also now supports nice filtering for |
121 | units via --unit=/-u. | |
122 | ||
6827101a | 123 | * Type=oneshot services may use ExecReload= and do the |
139ee8cc LP |
124 | right thing. |
125 | ||
126 | * The journal daemon now supports time-based rotation and | |
127 | vacuuming, in addition to the usual disk-space based | |
128 | rotation. | |
129 | ||
130 | * The journal will now index the available field values for | |
131 | each field name. This enables clients to show pretty drop | |
132 | downs of available match values when filtering. The bash | |
133 | completion of journalctl has been updated | |
134 | accordingly. journalctl gained a new switch -F to list all | |
135 | values a certain field takes in the journal database. | |
136 | ||
137 | * More service events are now written as structured messages | |
138 | to the journal, and made recognizable via message IDs. | |
139 | ||
140 | * The timedated, localed and hostnamed mini-services which | |
141 | previously only provided support for changing time, locale | |
142 | and hostname settings from graphical DEs such as GNOME now | |
143 | also have a minimal (but very useful) text-based client | |
144 | utility each. This is probably the nicest way to changing | |
145 | these settings from the command line now, especially since | |
146 | it lists available options and is fully integrated with bash | |
147 | completion. | |
148 | ||
149 | * There's now a new tool "systemd-coredumpctl" to list and | |
150 | extract coredumps from the journal. | |
151 | ||
152 | * We now install a README each in /var/log/ and | |
153 | /etc/rc.d/init.d explaining where the system logs and init | |
154 | scripts went. This hopefully should help folks who go to | |
155 | that dirs and look into the otherwise now empty void and | |
156 | scratch their heads. | |
157 | ||
158 | * When user-services are invoked (by systemd --user) the | |
159 | $MANAGERPID env var is set to the PID of systemd. | |
160 | ||
161 | * SIGRTMIN+24 when sent to a --user instance will now result | |
162 | in immediate termination of systemd. | |
163 | ||
164 | * gatewayd received numerous feature additions such as a | |
165 | "follow" mode, for live syncing and filtering. | |
166 | ||
167 | * browse.html now allows filtering and showing detailed | |
168 | information on specific entries. Keyboard navigation and | |
169 | mouse screen support has been added. | |
170 | ||
171 | * gatewayd/journalctl now supports HTML5/JSON | |
172 | Server-Sent-Events as output. | |
173 | ||
1cb88f2c | 174 | * The SysV init script compatibility logic will now |
139ee8cc LP |
175 | heuristically determine whether a script supports the |
176 | "reload" verb, and only then make this available as | |
177 | "systemctl reload". | |
178 | ||
15f47220 | 179 | * "systemctl status --follow" has been removed, use "journalctl |
139ee8cc LP |
180 | -u" instead. |
181 | ||
182 | * journald.conf's RuntimeMinSize=, PersistentMinSize= settings | |
183 | have been removed since they are hardly useful to be | |
184 | configured. | |
185 | ||
186 | * And I'd like to take the opportunity to specifically mention | |
187 | Zbigniew for his great contributions. Zbigniew, you rock! | |

197 | CHANGES WITH 194: |
198 | ||
199 | * If /etc/vconsole.conf is non-existent or empty we will no | |
200 | longer load any console font or key map at boot by | |
201 | default. Instead the kernel defaults will be left | |
202 | intact. This is definitely the right thing to do, as no | |
203 | configuration should mean no configuration, and hard-coding | |
204 | font names that are different on all archs is probably a bad | |
205 | idea. Also, the kernel default key map and font should be | |
206 | good enough for most cases anyway, and mostly identical to | |
207 | the userspace fonts/key maps we previously overloaded them | |
208 | with. If distributions want to continue to default to a | |
209 | non-kernel font or key map they should ship a default | |
210 | /etc/vconsole.conf with the appropriate contents. | |

216 | CHANGES WITH 193: |
217 | ||
218 | * journalctl gained a new --cursor= switch to show entries | |
219 | starting from the specified location in the journal. | |
220 | ||
221 | * We now enforce a size limit on journal entry fields exported | |
222 | with "-o json" in journalctl. Fields larger than 4K will be | |
223 | assigned null. This can be turned off with --all. | |
224 | ||
225 | * An (optional) journal gateway daemon is now available as | |
226 | "systemd-journal-gatewayd.service". This service provides | |
227 | access to the journal via HTTP and JSON. This functionality | |
228 | will be used to implement live log synchronization in both | |
229 | pull and push modes, but has various other users too, such | |
230 | as easy log access for debugging of embedded devices. Right | |
231 | now it is already useful to retrieve the journal via HTTP: | |
232 | ||
233 | # systemctl start systemd-journal-gatewayd.service | |
234 | # wget http://localhost:19531/entries | |
235 | ||
236 | This will download the journal contents in a | |
237 | /var/log/messages compatible format. The same as JSON: | |
238 | ||
239 | # curl -H"Accept: application/json" http://localhost:19531/entries | |
240 | ||
241 | This service is also accessible via a web browser where a | |
242 | single static HTML5 app is served that uses the JSON logic | |
243 | to enable the user to do some basic browsing of the | |
244 | journal. This will be extended later on. Here's an example | |
245 | screenshot of this app in its current state: | |

252 | CHANGES WITH 192: |
253 | ||
254 | * The bash completion logic is now available for journalctl | |
255 | too. | |
256 | ||
257 | * We don't mount the "cpuset" controller anymore together with | |
258 | "cpu" and "cpuacct", as "cpuset" groups generally cannot be | |
259 | started if no parameters are assigned to it. "cpuset" hence | |
260 | broke code that assumed it it could create "cpu" groups and | |
261 | just start them. | |
262 | ||
263 | * journalctl -f will now subscribe to terminal size changes, | |
264 | and line break accordingly. | |

269 | CHANGES WITH 191: |
270 | ||
271 | * nspawn will now create a symlink /etc/localtime in the | |
272 | container environment, copying the host's timezone | |
273 | setting. Previously this has been done via a bind mount, but | |
274 | since symlinks cannot be bind mounted this has now been | |
275 | changed to create/update the appropriate symlink. | |
276 | ||
277 | * journalctl -n's line number argument is now optional, and | |
278 | will default to 10 if omitted. | |
279 | ||
280 | * journald will now log the maximum size the journal files may | |
281 | take up on disk. This is particularly useful if the default | |
282 | built-in logic of determining this parameter from the file | |
283 | system size is used. Use "systemctl status | |
6563b535 | 284 | systemd-journald.service" to see this information. |
b6a86739 LP |
285 | |
286 | * The multi-seat X wrapper tool has been stripped down. As X | |
287 | is now capable of enumerating graphics devices via udev in a | |
288 | seat-aware way the wrapper is not strictly necessary | |
289 | anymore. A stripped down temporary stop-gap is still shipped | |
290 | until the upstream display managers have been updated to | |
291 | fully support the new X logic. Expect this wrapper to be | |
6563b535 | 292 | removed entirely in one of the next releases. |
b6a86739 LP |
293 | |
294 | * HandleSleepKey= in logind.conf has been split up into | |
295 | HandleSuspendKey= and HandleHibernateKey=. The old setting | |
6563b535 | 296 | is not available anymore. X11 and the kernel are |
b6a86739 LP |
297 | distuingishing between these keys and we should too. This |
298 | also means the inhibition lock for these keys has been split | |
299 | into two. | |

0c11f949 LP |
304 | CHANGES WITH 190: |
305 | ||
306 | * Whenever a unit changes state we'll now log this to the | |
307 | journal and show along the unit's own log output in | |
308 | "systemctl status". | |
309 | ||
310 | * ConditionPathIsMountPoint= can now properly detect bind | |
311 | mount points too. (Previously, a bind mount of one file | |
8d0256b7 | 312 | system to another place in the same file system could not be |
0c11f949 LP |
313 | detected as mount, since they shared struct stat's st_dev |
314 | field.) | |
315 | ||
316 | * We will now mount the cgroup controllers cpu, cpuacct, | |
317 | cpuset and the controllers net_cls, net_prio together by | |
318 | default. | |
319 | ||
320 | * nspawn containers will now have a virtualized boot | |
321 | ID. (i.e. /proc/sys/kernel/random/boot_id is now mounted | |
322 | over with a randomized ID at container initialization). This | |
323 | has the effect of making "journalctl -b" do the right thing | |
324 | in a container. | |
325 | ||
326 | * The JSON output journal serialization has been updated not | |
327 | to generate "endless" list objects anymore, but rather one | |
328 | JSON object per line. This is more in line how most JSON | |
329 | parsers expect JSON objects. The new output mode | |
330 | "json-pretty" has been added to provide similar output, but | |
331 | neatly aligned for readability by humans. | |
332 | ||
333 | * We dropped all explicit sync() invocations in the shutdown | |
334 | code. The kernel does this implicitly anyway in the kernel | |
335 | reboot() syscall. halt(8)'s -n option is now a compatibility | |
336 | no-op. | |
337 | ||
338 | * We now support virtualized reboot() in containers, as | |
339 | supported by newer kernels. We will fall back to exit() if | |
340 | CAP_SYS_REBOOT is not available to the container. Also, | |
341 | nspawn makes use of this now and will actually reboot the | |
342 | container if the containerized OS asks for that. | |
343 | ||
344 | * journalctl will only show local log output by default | |
345 | now. Use --merge (-m) to show remote log output, too. | |
346 | ||
347 | * libsystemd-journal gained the new sd_journal_get_usage() | |
348 | call to determine the current disk usage of all journal | |
349 | files. This is exposed in the new "journalctl --disk-usage" | |
350 | command. | |
351 | ||
352 | * journald gained a new configuration setting SplitMode= in | |
353 | journald.conf which may be used to control how user journals | |
354 | are split off. See journald.conf(5) for details. | |
355 | ||
356 | * A new condition type ConditionFileNotEmpty= has been added. | |
357 | ||
358 | * tmpfiles' "w" lines now support file globbing, to write | |
359 | multiple files at once. | |
360 | ||
361 | * We added Python bindings for the journal submission | |
362 | APIs. More Python APIs for a number of selected APIs will | |
363 | likely follow. Note that we intend to add native bindings | |
364 | only for the Python language, as we consider it common | |
365 | enough to deserve bindings shipped within systemd. There are | |
366 | various projects outside of systemd that provide bindings | |
367 | for languages such as PHP or Lua. | |
368 | ||
a98d5d64 LP |
369 | * Many conditions will now resolve specifiers such as %i. In |
370 | addition, PathChanged= and related directives of .path units | |
371 | now support specifiers as well. | |
0c11f949 LP |
372 | |
373 | * There's now a new RPM macro definition for the system preset | |
374 | dir: %_presetdir. | |
375 | ||
376 | * journald will now warn if it can't foward a message to the | |
377 | syslog daemon because it's socket is full. | |
378 | ||
379 | * timedated will no longer write or process /etc/timezone, | |
380 | except on Debian. As we do not support late mounted /usr | |
381 | anymore /etc/localtime always being a symlink is now safe, | |
382 | and hence the information in /etc/timezone is not necessary | |
383 | anymore. | |
384 | ||
aaccc32c | 385 | * logind will now always reserve one VT for a text getty (VT6 |
0c11f949 LP |
386 | by default). Previously if more than 6 X sessions where |
387 | started they took up all the VTs with auto-spawned gettys, | |
388 | so that no text gettys were available anymore. | |
389 | ||
390 | * udev will now automatically inform the btrfs kernel logic | |
391 | about btrfs RAID components showing up. This should make | |
392 | simple hotplug based btrfs RAID assembly work. | |
393 | ||
394 | * PID 1 will now increase its RLIMIT_NOFILE to 64K by default | |
395 | (but not for its children which will stay at the kernel | |
396 | default). This should allow setups with a lot more listening | |
397 | sockets. | |
398 | ||
399 | * systemd will now always pass the configured timezone to the | |
400 | kernel at boot. timedated will do the same when the timezone | |
401 | is changed. | |
402 | ||
403 | * logind's inhibition logic has been updated. By default, | |
404 | logind will now handle the lid switch, the power and sleep | |
405 | keys all the time, even in graphical sessions. If DEs want | |
406 | to handle these events on their own they should take the new | |
407 | handle-power-key, handle-sleep-key and handle-lid-switch | |
408 | inhibitors during their runtime. A simple way to achiveve | |
409 | that is to invoke the DE wrapped in an invocation of: | |
410 | ||
411 | systemd-inhibit --what=handle-power-key:handle-sleep-key:handle-lid-switch ... | |
412 | ||
413 | * Access to unit operations is now checked via SELinux taking | |
414 | the unit file label and client process label into account. | |
415 | ||
aad803af LP |
416 | * systemd will now notify the administrator in the journal |
417 | when he over-mounts a non-empty directory. | |
418 | ||
419 | * There are new specifiers that are resolved in unit files, | |
420 | for the host name (%H), the machine ID (%m) and the boot ID | |
421 | (%b). | |

431 | CHANGES WITH 189: |
432 | ||
433 | * Support for reading structured kernel messages from | |
434 | /dev/kmsg has now been added and is enabled by default. | |
435 | ||
436 | * Support for reading kernel messages from /proc/kmsg has now | |
437 | been removed. If you want kernel messages in the journal | |
438 | make sure to run a recent kernel (>= 3.5) that supports | |
439 | reading structured messages from /dev/kmsg (see | |
440 | above). /proc/kmsg is now exclusive property of classic | |
441 | syslog daemons again. | |
442 | ||
443 | * The libudev API gained the new | |
444 | udev_device_new_from_device_id() call. | |
445 | ||
446 | * The logic for file system namespace (ReadOnlyDirectory=, | |
447 | ReadWriteDirectoy=, PrivateTmp=) has been reworked not to | |
448 | require pivot_root() anymore. This means fewer temporary | |
449 | directories are created below /tmp for this feature. | |
450 | ||
451 | * nspawn containers will now see and receive all submounts | |
452 | made on the host OS below the root file system of the | |
453 | container. | |
454 | ||
455 | * Forward Secure Sealing is now supported for Journal files, | |
456 | which provide cryptographical sealing of journal files so | |
457 | that attackers cannot alter log history anymore without this | |
458 | being detectable. Lennart will soon post a blog story about | |
459 | this explaining it in more detail. | |
460 | ||
461 | * There are two new service settings RestartPreventExitStatus= | |
462 | and SuccessExitStatus= which allow configuration of exit | |
463 | status (exit code or signal) which will be excepted from the | |
464 | restart logic, resp. consider successful. | |
465 | ||
466 | * journalctl gained the new --verify switch that can be used | |
467 | to check the integrity of the structure of journal files and | |
468 | (if Forward Secure Sealing is enabled) the contents of | |
469 | journal files. | |
470 | ||
471 | * nspawn containers will now be run with /dev/stdin, /dev/fd/ | |
472 | and similar symlinks pre-created. This makes running shells | |
473 | as container init process a lot more fun. | |
474 | ||
475 | * The fstab support can now handle PARTUUID= and PARTLABEL= | |
476 | entries. | |
477 | ||
478 | * A new ConditionHost= condition has been added to match | |
479 | against the hostname (with globs) and machine ID. This is | |
480 | useful for clusters where a single OS image is used to | |
481 | provision a large number of hosts which shall run slightly | |
482 | different sets of services. | |
483 | ||
484 | * Services which hit the restart limit will now be placed in a | |
485 | failure state. | |

491 | CHANGES WITH 188: |
492 | ||
493 | * When running in --user mode systemd will now become a | |
494 | subreaper (PR_SET_CHILD_SUBREAPER). This should make the ps | |
495 | tree a lot more organized. | |
496 | ||
497 | * A new PartOf= unit dependency type has been introduced that | |
498 | may be used to group services in a natural way. | |
499 | ||
500 | * "systemctl enable" may now be used to enable instances of | |
501 | services. | |
502 | ||
503 | * journalctl now prints error log levels in red, and | |
504 | warning/notice log levels in bright white. It also supports | |
505 | filtering by log level now. | |
506 | ||
507 | * cgtop gained a new -n switch (similar to top), to configure | |
508 | the maximum number of iterations to run for. It also gained | |
509 | -b, to run in batch mode (accepting no input). | |
510 | ||
511 | * The suffix ".service" may now be ommited on most systemctl | |
512 | command lines involving service unit names. | |
513 | ||
514 | * There's a new bus call in logind to lock all sessions, as | |
515 | well as a loginctl verb for it "lock-sessions". | |
516 | ||
517 | * libsystemd-logind.so gained a new call sd_journal_perror() | |
518 | that works similar to libc perror() but logs to the journal | |
519 | and encodes structured information about the error number. | |
520 | ||
521 | * /etc/crypttab entries now understand the new keyfile-size= | |
522 | option. | |
523 | ||
524 | * shutdown(8) now can send a (configurable) wall message when | |
525 | a shutdown is cancelled. | |
526 | ||
527 | * The mount propagation mode for the root file system will now | |
528 | default to "shared", which is useful to make containers work | |
529 | nicely out-of-the-box so that they receive new mounts from | |
530 | the host. This can be undone locally by running "mount | |
531 | --make-rprivate /" if needed. | |
532 | ||
533 | * The prefdm.service file has been removed. Distributions | |
534 | should maintain this unit downstream if they intend to keep | |
535 | it around. However, we recommend writing normal unit files | |
536 | for display managers instead. | |
537 | ||
538 | * Since systemd is a crucial part of the OS we will now | |
539 | default to a number of compiler switches that improve | |
540 | security (hardening) such as read-only relocations, stack | |
541 | protection, and suchlike. | |
542 | ||
543 | * The TimeoutSec= setting for services is now split into | |
544 | TimeoutStartSec= and TimeoutStopSec= to allow configuration | |
545 | of individual time outs for the start and the stop phase of | |
546 | the service. | |

c4f1b862 LP |
555 | CHANGES WITH 187: |
556 | ||
557 | * The journal and id128 C APIs are now fully documented as man | |
558 | pages. | |
559 | ||
560 | * Extra safety checks have been added when transitioning from | |
561 | the initial RAM disk to the main system to avoid accidental | |
562 | data loss. | |
563 | ||
c269cec3 | 564 | * /etc/crypttab entries now understand the new keyfile-offset= |
c4f1b862 LP |
565 | option. |
566 | ||
567 | * systemctl -t can now be used to filter by unit load state. | |
568 | ||
569 | * The journal C API gained the new sd_journal_wait() call to | |
570 | make writing synchronous journal clients easier. | |
571 | ||
572 | * journalctl gained the new -D switch to show journals from a | |
573 | specific directory. | |
574 | ||
575 | * journalctl now displays a special marker between log | |
576 | messages of two different boots. | |
577 | ||
578 | * The journal is now explicitly flushed to /var via a service | |
579 | systemd-journal-flush.service, rather than implicitly simply | |
580 | by seeing /var/log/journal to be writable. | |
581 | ||
582 | * journalctl (and the journal C APIs) can now match for much | |
583 | more complex expressions, with alternatives and | |
584 | disjunctions. | |
585 | ||
586 | * When transitioning from the initial RAM disk to the main | |
587 | system we will now kill all processes in a killing spree to | |
588 | ensure no processes stay around by accident. | |
589 | ||
590 | * Three new specifiers may be used in unit files: %u, %h, %s | |
591 | resolve to the user name, user home directory resp. user | |
592 | shell. This is useful for running systemd user instances. | |
593 | ||
594 | * We now automatically rotate journal files if their data | |
595 | object hash table gets a fill level > 75%. We also size the | |
596 | hash table based on the configured maximum file size. This | |
597 | together should lower hash collisions drastically and thus | |
598 | speed things up a bit. | |
599 | ||
600 | * journalctl gained the new "--header" switch to introspect | |
601 | header data of journal files. | |
602 | ||
603 | * A new setting SystemCallFilters= has been added to services | |
604 | which may be used to apply blacklists or whitelists to | |
605 | system calls. This is based on SECCOMP Mode 2 of Linux 3.5. | |
606 | ||
607 | * nspawn gained a new --link-journal= switch (and quicker: -j) | |
608 | to link the container journal with the host. This makes it | |
609 | very easy to centralize log viewing on the host for all | |
610 | guests while still keeping the journal files separated. | |
611 | ||
612 | * Many bugfixes and optimizations | |

b5b4c94a LP |
619 | CHANGES WITH 186: |
620 | ||
621 | * Several tools now understand kernel command line arguments, | |
622 | which are only read when run in an initial RAM disk. They | |
623 | usually follow closely their normal counterparts, but are | |
624 | prefixed with rd. | |
625 | ||
626 | * There's a new tool to analyze the readahead files that are | |
627 | automatically generated at boot. Use: | |
628 | ||
629 | /usr/lib/systemd/systemd-readahead analyze /.readahead | |
630 | ||
631 | * We now provide an early debug shell on tty9 if this enabled. Use: | |
632 | ||
d1f9edaf | 633 | systemctl enable debug-shell.service |
b5b4c94a LP |
634 | |
635 | * All plymouth related units have been moved into the Plymouth | |
636 | package. Please make sure to upgrade your Plymouth version | |
637 | as well. | |
638 | ||
639 | * systemd-tmpfiles now supports getting passed the basename of | |
640 | a configuration file only, in which case it will look for it | |
641 | in all appropriate directories automatically. | |
642 | ||
643 | * udevadm info now takes a /dev or /sys path as argument, and | |
644 | does the right thing. Example: | |
645 | ||
646 | udevadm info /dev/sda | |
647 | udevadm info /sys/class/block/sda | |
648 | ||
649 | * systemctl now prints a warning if a unit is stopped but a | |
650 | unit that might trigger it continues to run. Example: a | |
651 | service is stopped but the socket that activates it is left | |
652 | running. | |
653 | ||
654 | * "systemctl status" will now mention if the log output was | |
655 | shortened due to rotation since a service has been started. | |
656 | ||
657 | * The journal API now exposes functions to determine the | |
658 | "cutoff" times due to rotation. | |
659 | ||
660 | * journald now understands SIGUSR1 and SIGUSR2 for triggering | |
661 | immediately flushing of runtime logs to /var if possible, | |
662 | resp. for triggering immediate rotation of the journal | |
663 | files. | |
664 | ||
665 | * It is now considered an error if a service is attempted to | |
666 | be stopped that is not loaded. | |
667 | ||
668 | * XDG_RUNTIME_DIR now uses numeric UIDs instead of usernames. | |
669 | ||
670 | * systemd-analyze now supports Python 3 | |
671 | ||
672 | * tmpfiles now supports cleaning up directories via aging | |
673 | where the first level dirs are always kept around but | |
674 | directories beneath it automatically aged. This is enabled | |
675 | by prefixing the age field with '~'. | |
676 | ||
677 | * Seat objects now expose CanGraphical, CanTTY properties | |
678 | which is required to deal with very fast bootups where the | |
679 | display manager might be running before the graphics drivers | |
680 | completed initialization. | |
681 | ||
682 | * Seat objects now expose a State property. | |
683 | ||
684 | * We now include RPM macros for service enabling/disabling | |
685 | based on the preset logic. We recommend RPM based | |
686 | distributions to make use of these macros if possible. This | |
687 | makes it simpler to reuse RPM spec files across | |
688 | distributions. | |
689 | ||
690 | * We now make sure that the collected systemd unit name is | |
691 | always valid when services log to the journal via | |
692 | STDOUT/STDERR. | |
693 | ||
694 | * There's a new man page kernel-command-line(7) detailing all | |
695 | command line options we understand. | |
696 | ||
697 | * The fstab generator may now be disabled at boot by passing | |
698 | fstab=0 on the kernel command line. | |
699 | ||
91ac7425 | 700 | * A new kernel command line option modules-load= is now understood |
b5b4c94a LP |
701 | to load a specific kernel module statically, early at boot. |
702 | ||
703 | * Unit names specified on the systemctl command line are now | |
704 | automatically escaped as needed. Also, if file system or | |
705 | device paths are specified they are automatically turned | |
706 | into the appropriate mount or device unit names. Example: | |
707 | ||
708 | systemctl status /home | |
709 | systemctl status /dev/sda | |
710 | ||
711 | * The SysVConsole= configuration option has been removed from | |
712 | system.conf parsing. | |
713 | ||
714 | * The SysV search path is no longer exported on the D-Bus | |
715 | Manager object. | |
716 | ||
717 | * The Names= option is been removed from unit file parsing. | |
718 | ||
719 | * There's a new man page bootup(7) detailing the boot process. | |
720 | ||
721 | * Every unit and every generator we ship with systemd now | |
722 | comes with full documentation. The self-explanatory boot is | |
723 | complete. | |
724 | ||
725 | * A couple of services gained "systemd-" prefixes in their | |
726 | name if they wrap systemd code, rather than only external | |
727 | code. Among them fsck@.service which is now | |
728 | systemd-fsck@.service. | |
729 | ||
730 | * The HaveWatchdog property has been removed from the D-Bus | |
731 | Manager object. | |
732 | ||
733 | * systemd.confirm_spawn= on the kernel command line should now | |
734 | work sensibly. | |
735 | ||
736 | * There's a new man page crypttab(5) which details all options | |
737 | we actually understand. | |
738 | ||
739 | * systemd-nspawn gained a new --capability= switch to pass | |
740 | additional capabilities to the container. | |
741 | ||
742 | * timedated will now read known NTP implementation unit names | |
5b00c016 | 743 | from /usr/lib/systemd/ntp-units.d/*.list, |
b5b4c94a LP |
744 | systemd-timedated-ntp.target has been removed. |
745 | ||
746 | * journalctl gained a new switch "-b" that lists log data of | |
747 | the current boot only. | |
748 | ||
749 | * The notify socket is in the abstract namespace again, in | |
750 | order to support daemons which chroot() at start-up. | |
751 | ||
752 | * There is a new Storage= configuration option for journald | |
753 | which allows configuration of where log data should go. This | |
754 | also provides a way to disable journal logging entirely, so | |
755 | that data collected is only forwarded to the console, the | |
756 | kernel log buffer or another syslog implementation. | |
757 | ||

771 | ||
b5b4c94a LP |
772 | * MaxLevelStore=, MaxLevelSyslog=, MaxLevelKMsg=, |
773 | MaxLevelConsole= can now be specified in | |
774 | journald.conf. These options allow reducing the amount of | |
775 | data stored on disk or forwarded by the log level. | |
2d197285 | 776 | |
b5b4c94a LP |
777 | * TimerSlackNSec= can now be specified in system.conf for |

787 | sleep keys as well as the lid switch. | |
788 | ||
789 | * journalctl now understands the syntax "journalctl | |
790 | /usr/bin/avahi-daemon" to get all log output of a specific | |
791 | daemon. | |
792 | ||
793 | * CapabilityBoundingSet= in system.conf now also influences | |

ea5943d3 | 801 | CHANGES WITH 183: |
b6a86739 | 802 | |
187076d4 LP |
803 | * Note that we skipped 139 releases here in order to set the |
804 | new version to something that is greater than both udev's | |
805 | and systemd's most recent version number. | |
806 | ||
194bbe33 KS |
807 | * udev: all udev sources are merged into the systemd source tree now. |
808 | All future udev development will happen in the systemd tree. It | |
809 | is still fully supported to use the udev daemon and tools without | |
810 | systemd running, like in initramfs or other init systems. Building | |
811 | udev though, will require the *build* of the systemd tree, but | |
ea5943d3 | 812 | udev can be properly *run* without systemd. |
07cd4fc1 | 813 | |
91cf7e5c | 814 | * udev: /lib/udev/devices/ are not read anymore; systemd-tmpfiles |
f13b388f KS |
815 | should be used to create dead device nodes as workarounds for broken |
816 | subsystems. | |
64661ee7 | 817 | |
2d13da88 KS |
818 | * udev: RUN+="socket:..." and udev_monitor_new_from_socket() is |
819 | no longer supported. udev_monitor_new_from_netlink() needs to be | |
820 | used to subscribe to events. | |
821 | ||
194bbe33 KS |
822 | * udev: when udevd is started by systemd, processes which are left |
823 | behind by forking them off of udev rules, are unconditionally cleaned | |
824 | up and killed now after the event handling has finished. Services or | |
825 | daemons must be started as systemd services. Services can be | |
ea5943d3 | 826 | pulled-in by udev to get started, but they can no longer be directly |
194bbe33 KS |
827 | forked by udev rules. |
828 | ||
f13b388f KS |
829 | * udev: the daemon binary is called systemd-udevd now and installed |
830 | in /usr/lib/systemd/. Standalone builds or non-systemd systems need | |
831 | to adapt to that, create symlink, or rename the binary after building | |
832 | it. | |
833 | ||
ea5943d3 | 834 | * libudev no longer provides these symbols: |
c1959569 KS |
835 | udev_monitor_from_socket() |
836 | udev_queue_get_failed_list_entry() | |
837 | udev_get_{dev,sys,run}_path() | |
ea5943d3 | 838 | The versions number was bumped and symbol versioning introduced. |
c1959569 | 839 | |
ea5943d3 | 840 | * systemd-loginctl and systemd-journalctl have been renamed |
9ae9afce | 841 | to loginctl and journalctl to match systemctl. |
18b754d3 KS |
842 | |
843 | * The config files: /etc/systemd/systemd-logind.conf and | |
844 | /etc/systemd/systemd-journald.conf have been renamed to | |
845 | logind.conf and journald.conf. Package updates should rename | |
846 | the files to the new names on upgrade. | |
847 | ||
ea5943d3 LP |
848 | * For almost all files the license is now LGPL2.1+, changed |
849 | from the previous GPL2.0+. Exceptions are some minor stuff | |
850 | of udev (which will be changed to LGPL2.1 eventually, too), | |
851 | and the MIT licensed sd-daemon.[ch] library that is suitable | |
852 | to be used as drop-in files. | |
853 | ||
854 | * systemd and logind now handle system sleep states, in | |
49f43d5f | 855 | particular suspending and hibernating. |
ea5943d3 LP |
856 | |
857 | * logind now implements a sleep/shutdown/idle inhibiting logic | |
858 | suitable for a variety of uses. Soonishly Lennart will blog | |
859 | about this in more detail. | |
860 | ||
861 | * var-run.mount and var-lock.mount are no longer provided | |
862 | (which prevously bind mounted these directories to their new | |
863 | places). Distributions which have not converted these | |
864 | directories to symlinks should consider stealing these files | |
865 | from git history and add them downstream. | |
866 | ||
867 | * We introduced the Documentation= field for units and added | |
868 | this to all our shipped units. This is useful to make it | |
3943231c | 869 | easier to explore the boot and the purpose of the various |
ea5943d3 LP |
870 | units. |
871 | ||
872 | * All smaller setup units (such as | |
873 | systemd-vconsole-setup.service) now detect properly if they | |
874 | are run in a container and are skipped when | |
875 | appropriate. This guarantees an entirely noise-free boot in | |
876 | Linux container environments such as systemd-nspawn. | |
877 | ||
878 | * A framework for implementing offline system updates is now | |
879 | integrated, for details see: | |
880 | http://freedesktop.org/wiki/Software/systemd/SystemUpdates | |
881 | ||
882 | * A new service type Type=idle is available now which helps us | |
883 | avoiding ugly interleaving of getty output and boot status | |
884 | messages. | |
885 | ||
439d6dfd LP |
886 | * There's now a system-wide CapabilityBoundingSet= option to |
887 | globally reduce the set of capabilities for the | |

888 | system. This is useful to drop CAP_SYS_MKNOD, CAP_SYS_RAWIO, |
889 | CAP_NET_RAW, CAP_SYS_MODULE, CAP_SYS_TIME, CAP_SYS_PTRACE or | |
890 | even CAP_NET_ADMIN system-wide for secure systems. | |
891 | ||
892 | * There are now system-wide DefaultLimitXXX= options to | |
893 | globally change the defaults of the various resource limits | |
894 | for all units started by PID 1. | |
895 | ||
896 | * Harald Hoyer's systemd test suite has been integrated into | |
897 | systemd which allows easy testing of systemd builds in qemu | |
898 | and nspawn. (This is really awesome! Ask us for details!) | |
899 | ||
3943231c LP |
900 | * The fstab parser is now implemented as generator, not inside |
901 | of PID 1 anymore. | |
ea5943d3 LP |
902 | |
903 | * systemctl will now warn you if .mount units generated from | |
904 | /etc/fstab are out of date due to changes in fstab that | |
905 | haven't been read by systemd yet. | |
906 | ||
907 | * systemd is now suitable for usage in initrds. Dracut has | |
908 | already been updated to make use of this. With this in place | |
909 | initrds get a slight bit faster but primarily are much | |
910 | easier to introspect and debug since "systemctl status" in | |
911 | the host system can be used to introspect initrd services, | |
912 | and the journal from the initrd is kept around too. | |
913 | ||
914 | * systemd-delta has been added, a tool to explore differences | |
915 | between user/admin configuration and vendor defaults. | |
916 | ||
917 | * PrivateTmp= now affects both /tmp and /var/tmp. | |
918 | ||
919 | * Boot time status messages are now much prettier and feature | |
920 | proper english language. Booting up systemd has never been | |
921 | so sexy. | |
922 | ||
923 | * Read-ahead pack files now include the inode number of all | |
924 | files to pre-cache. When the inode changes the pre-caching | |
925 | is not attempted. This should be nicer to deal with updated | |
926 | packages which might result in changes of read-ahead | |
927 | patterns. | |
928 | ||
929 | * We now temporaritly lower the kernel's read_ahead_kb variable | |
930 | when collecting read-ahead data to ensure the kernel's | |
931 | built-in read-ahead does not add noise to our measurements | |
932 | of necessary blocks to pre-cache. | |
933 | ||
934 | * There's now RequiresMountsFor= to add automatic dependencies | |
935 | for all mounts necessary for a specific file system path. | |
936 | ||
937 | * MountAuto= and SwapAuto= have been removed from | |
938 | system.conf. Mounting file systems at boot has to take place | |
939 | in systemd now. | |
940 | ||
941 | * nspawn now learned a new switch --uuid= to set the machine | |
942 | ID on the command line. | |
943 | ||
f8c0a2cb | 944 | * nspawn now learned the -b switch to automatically search |
ea5943d3 LP |
945 | for an init system. |
946 | ||
947 | * vt102 is now the default TERM for serial TTYs, upgraded from | |
948 | vt100. | |
949 | ||
950 | * systemd-logind now works on VT-less systems. | |
951 | ||
952 | * The build tree has been reorganized. The individual | |
3943231c | 953 | components now have directories of their own. |
ea5943d3 LP |
954 | |
955 | * A new condition type ConditionPathIsReadWrite= is now available. | |
956 | ||
957 | * nspawn learned the new -C switch to create cgroups for the | |
958 | container in other hierarchies. | |
959 | ||
960 | * We now have support for hardware watchdogs, configurable in | |
961 | system.conf. | |
962 | ||
963 | * The scheduled shutdown logic now has a public API. | |
964 | ||
965 | * We now mount /tmp as tmpfs by default, but this can be | |
966 | masked and /etc/fstab can override it. | |
967 | ||
968 | * Since udisks doesn't make use of /media anymore we are not | |
969 | mounting a tmpfs on it anymore. | |
970 | ||
971 | * journalctl gained a new --local switch to only interleave | |
972 | locally generated journal files. | |
973 | ||
974 | * We can now load the IMA policy at boot automatically. | |
975 | ||
976 | * The GTK tools have been split off into a systemd-ui. | |

16f1239e | 989 | CHANGES WITH 44: |
b6a86739 | 990 | |
16f1239e LP |
991 | * This is mostly a bugfix release |
992 | ||
993 | * Support optional initialization of the machine ID from the | |
994 | KVM or container configured UUID. | |
995 | ||
996 | * Support immediate reboots with "systemctl reboot -ff" | |
997 | ||
998 | * Show /etc/os-release data in systemd-analyze output | |
999 | ||
1000 | * Many bugfixes for the journal, including endianess fixes and | |
1001 | ensuring that disk space enforcement works | |
1002 | ||
1003 | * sd-login.h is C++ comptaible again | |
1004 | ||
1005 | * Extend the /etc/os-release format on request of the Debian | |
1006 | folks | |
1007 | ||
1008 | * We now refuse non-UTF8 strings used in various configuration | |
1009 | and unit files. This is done to ensure we don't pass invalid | |
1010 | data over D-Bus or expose it elsewhere. | |
1011 | ||
1012 | * Register Mimo USB Screens as suitable for automatic seat | |
1013 | configuration | |
1014 | ||
1015 | * Read SELinux client context from journal clients in a race | |
1016 | free fashion | |
1017 | ||
1018 | * Reorder configuration file lookup order. /etc now always | |
1019 | overrides /run in order to allow the administrator to always | |
1020 | and unconditionally override vendor supplied or | |
1021 | automatically generated data. | |
1022 | ||
1023 | * The various user visible bits of the journal now have man | |
1024 | pages. We still lack man pages for the journal API calls | |
1025 | however. | |
1026 | ||
1027 | * We now ship all man pages in HTML format again in the | |
1028 | tarball. | |

437b7dee LP |
1037 | * This is mostly a bugfix release |
1038 | ||
1039 | * systems lacking /etc/os-release are no longer supported. | |
1040 | ||
1041 | * Various functionality updates to libsystemd-login.so | |
1042 | ||
1043 | * Track class of PAM logins to distuingish greeters from | |
1044 | normal user logins. | |

b6a86739 | 1050 | |
204fa33c LP |
1051 | * This is an important bugfix release for v41. |
1052 | ||
1053 | * Building man pages is now optional which should be useful | |
1054 | for those building systemd from git but unwilling to install | |
1055 | xsltproc. | |
1056 | ||
1057 | * Watchdog support for supervising services is now usable. In | |
1058 | a future release support for hardware watchdogs | |
1059 | (i.e. /dev/watchdog) will be added building on this. | |
1060 | ||
1061 | * Service start rate limiting is now configurable and can be | |
1062 | turned off per service. When a start rate limit is hit a | |
1063 | reboot can automatically be triggered. | |
1064 | ||
1065 | * New CanReboot(), CanPowerOff() bus calls in systemd-logind. | |

e0d25329 | 1071 | CHANGES WITH 41: |
b6a86739 | 1072 | |
e0d25329 KS |
1073 | * The systemd binary is installed /usr/lib/systemd/systemd now; |
1074 | An existing /sbin/init symlink needs to be adapted with the | |
1075 | package update. | |
1076 | ||
b13df964 LP |
1077 | * The code that loads kernel modules has been ported to invoke |
1078 | libkmod directly, instead of modprobe. This means we do not | |
1079 | support systems with module-init-tools anymore. | |
1080 | ||
1081 | * Watchdog support is now already useful, but still not | |
1082 | complete. | |
1083 | ||
1084 | * A new kernel command line option systemd.setenv= is | |
1085 | understood to set system wide environment variables | |
1086 | dynamically at boot. | |
1087 | ||
ccd07a08 LP |
1088 | * We now limit the set of capabilities of systemd-journald. |
1089 | ||
353e12c2 LP |
1090 | * We now set SIGPIPE to ignore by default, since it only is |
1091 | useful in shell pipelines, and has little use in general | |
1092 | code. This can be disabled with IgnoreSIPIPE=no in unit | |
1093 | files. | |

b6a86739 | 1100 | |
d26e4270 LP |
1101 | * This is mostly a bugfix release |
1102 | ||
1103 | * We now expose the reason why a service failed in the | |
1104 | "Result" D-Bus property. | |
1105 | ||
1106 | * Rudimentary service watchdog support (will be completed over | |
1107 | the next few releases.) | |
1108 | ||
1109 | * When systemd forks off in order execute some service we will | |
1110 | now immediately changes its argv[0] to reflect which process | |
1111 | it will execute. This is useful to minimize the time window | |
1112 | with a generic argv[0], which makes bootcharts more useful | |

220a21d3 | 1118 | CHANGES WITH 39: |
b6a86739 | 1119 | |
220a21d3 LP |
1120 | * This is mostly a test release, but incorporates many |
1121 | bugfixes. | |
1122 | ||
1123 | * New systemd-cgtop tool to show control groups by their | |
1124 | resource usage. | |
1125 | ||
1126 | * Linking against libacl for ACLs is optional again. If | |
1127 | disabled, support tracking device access for active logins | |
1128 | goes becomes unavailable, and so does access to the user | |
1129 | journals by the respective users. | |
1130 | ||
1131 | * If a group "adm" exists, journal files are automatically | |
1132 | owned by them, thus allow members of this group full access | |
1133 | to the system journal as well as all user journals. | |
1134 | ||
1135 | * The journal now stores the SELinux context of the logging | |
1136 | client for all entries. | |
1137 | ||
1138 | * Add C++ inclusion guards to all public headers | |
1139 | ||
1140 | * New output mode "cat" in the journal to print only text | |
1141 | messages, without any meta data like date or time. | |
1142 | ||
1143 | * Include tiny X server wrapper as a temporary stop-gap to | |
1144 | teach XOrg udev display enumeration. This is used by display | |
1145 | managers such as gdm, and will go away as soon as XOrg | |
1146 | learned native udev hotplugging for display devices. | |
1147 | ||
1148 | * Add new systemd-cat tool for executing arbitrary programs | |
1149 | with STDERR/STDOUT connected to the journal. Can also act as | |
1150 | BSD logger replacement, and does so by default. | |
1151 | ||
1152 | * Optionally store all locally generated coredumps in the | |
1153 | journal along with meta data. | |
1154 | ||
1155 | * systemd-tmpfiles learnt four new commands: n, L, c, b, for | |
1156 | writing short strings to files (for usage for /sys), and for | |
1157 | creating symlinks, character and block device nodes. | |
1158 | ||
1159 | * New unit file option ControlGroupPersistent= to make cgroups | |
1160 | persistent, following the mechanisms outlined in | |
1161 | http://www.freedesktop.org/wiki/Software/systemd/PaxControlGroups | |
1162 | ||
1163 | * Support multiple local RTCs in a sane way | |
1164 | ||
1165 | * No longer monopolize IO when replaying readahead data on | |
1166 | rotating disks, since we might starve non-file-system IO to | |
1167 | death, since fanotify() will not see accesses done by blkid, | |
1168 | or fsck. | |
1169 | ||
1170 | * Don't show kernel threads in systemd-cgls anymore, unless | |
1171 | requested with new -k switch. | |

1176 | CHANGES WITH 38: | |
b6a86739 | 1177 | |
220a21d3 LP |
1178 | * This is mostly a test release, but incorporates many |
1179 | bugfixes. | |
1180 | ||
1181 | * The git repository moved to: | |
1182 | git://anongit.freedesktop.org/systemd/systemd | |
1183 | ssh://git.freedesktop.org/git/systemd/systemd | |
1184 | ||
1185 | * First release with the journal | |
1186 | http://0pointer.de/blog/projects/the-journal.html | |
1187 | ||
1188 | * The journal replaces both systemd-kmsg-syslogd and | |
1189 | systemd-stdout-bridge. | |
1190 | ||
1191 | * New sd_pid_get_unit() API call in libsystemd-logind | |
1192 | ||
1193 | * Many systemadm clean-ups | |
1194 | ||
1195 | * Introduce remote-fs-pre.target which is ordered before all | |
1196 | remote mounts and may be used to start services before all | |
1197 | remote mounts. | |
1198 | ||
1199 | * Added Mageia support | |
1200 | ||
1201 | * Add bash completion for systemd-loginctl | |
1202 | ||
1203 | * Actively monitor PID file creation for daemons which exit in | |
1204 | the parent process before having finished writing the PID | |
1205 | file in the daemon process. Daemons which do this need to be | |
1206 | fixed (i.e. PID file creation must have finished before the | |
1207 | parent exits), but we now react a bit more gracefully to them. | |
1208 | ||
1209 | * Add colourful boot output, mimicking the well-known output | |
1210 | of existing distributions. | |
1211 | ||
1212 | * New option PassCredentials= for socket units, for | |
1213 | compatibility with a recent kernel ABI breakage. | |
1214 | ||
1215 | * /etc/rc.local is now hooked in via a generator binary, and | |
1216 | thus will no longer act as synchronization point during | |
1217 | boot. | |
1218 | ||
1219 | * systemctl list-unit-files now supports --root=. | |
1220 | ||
1221 | * systemd-tmpfiles now understands two new commands: z, Z for | |
1222 | relabelling files according to the SELinux database. This is | |
1223 | useful to apply SELinux labels to specific files in /sys, | |
1224 | among other things. | |
1225 | ||
1226 | * Output of SysV services is now forwarded to both the console | |
1227 | and the journal by default, not only just the console. | |
1228 | ||
1229 | * New man pages for all APIs from libsystemd-login. | |
1230 | ||
1231 | * The build tree got reorganized and a the build system is a | |
1232 | lot more modular allowing embedded setups to specifically | |
1233 | select the components of systemd they are interested in. | |
1234 | ||
1235 | * Support for Linux systems lacking the kernel VT subsystem is | |
1236 | restored. | |
1237 | ||
1238 | * configure's --with-rootdir= got renamed to | |
1239 | --with-rootprefix= to follow the naming used by udev and | |
1240 | kmod | |
1241 | ||
1242 | * Unless specified otherwise we'll now install to /usr instead | |
1243 | of /usr/local by default. | |
1244 | ||
1245 | * Processes with '@' in argv[0][0] are now excluded from the | |
1246 | final shut-down killing spree, following the logic explained | |
1247 | in: | |
1248 | http://www.freedesktop.org/wiki/Software/systemd/RootStorageDaemons | |
1249 | ||
1250 | * All processes remaining in a service cgroup when we enter | |
1251 | the START or START_PRE states are now killed with | |
1252 | SIGKILL. That means it is no longer possible to spawn | |
1253 | background processes from ExecStart= lines (which was never | |
1254 | supported anyway, and bad style). | |
1255 | ||
1256 | * New PropagateReloadTo=/PropagateReloadFrom= options to bind | |
1257 | reloading of units together. | |
