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 | |
96ec33c0 | 13 | database was only attached to select devices, since the |
0428ddb7 | 14 | lookup was a relatively expensive operation due to O(n) time |
96ec33c0 LP |
15 | complexity (with n being the number of entries in the |
16 | database). Since this is now O(1), we decided to add in this | |
17 | data for all devices where this is available, by | |
0428ddb7 LP |
18 | default. Note that the indexed database needs to be rebuilt |
19 | when new data files are installed. To achieve this you need | |
20 | to update your packaging scripts to invoke "udevadm hwdb | |
21 | --update" after installation of hwdb data files. For | |
22 | RPM-based distributions we introduced the new | |
23 | %udev_hwdb_update macro for this purpose. | |
24 | ||
25 | * The Journal gained support for the "Message Catalog", an | |
26 | indexed database to link up additional information with | |
27 | journal entries. For further details please check: | |
28 | ||
29 | http://www.freedesktop.org/wiki/Software/systemd/catalog | |
30 | ||
31 | The indexed message catalog database also needs to be | |
32 | rebuilt after installation of message catalog files. Use | |
33 | "journalctl --update-catalog" for this. For RPM-based | |
34 | distributions we introduced the %journal_catalog_update | |
35 | macro for this purpose. | |
36 | ||
37 | * The Python Journal bindings gained support for the standard | |
38 | Python logging framework. | |
39 | ||
40 | * The Journal API gained new functions for checking whether | |
41 | the underlying file system of a journal file is capable of | |
42 | properly reporting file change notifications, or whether | |
43 | applications that want to reflect journal changes "live" | |
44 | need to recheck journal files continously in appropriate | |
45 | time intervals. | |
46 | ||
47 | * It is now possible to set the "age" field for tmpfiles | |
48 | entries to 0, indicating that files matching this entry | |
49 | shall always be removed when the directories are cleaned up. | |
50 | ||
51 | * coredumpctl gained a new "gdb" verb which invokes gdb | |
52 | right-away on the selected coredump. | |
53 | ||
54 | * There's now support for "hybrid sleep" on kernels that | |
55 | support this, in addition to "suspend" and "hibernate". Use | |
56 | "systemctl hybrid-sleep" to make use of this. | |
57 | ||
58 | * logind's HandleSuspendKey= setting (and related settings) | |
59 | now gained support for a new "lock" setting to simply | |
60 | request the screen lock on all local sessions, instead of | |
61 | actually executing a suspend or hibernation. | |
62 | ||
63 | * systemd will now mount the EFI variables file system by | |
64 | default. | |
65 | ||
66 | * Socket units now gained support for configuration of the | |
67 | SMACK security label. | |
68 | ||
69 | * timedatectl will now output the time of the last and next | |
70 | daylight saving change. | |
71 | ||
72 | * We dropped support for various legacy and distro-specific | |
73 | concepts, such as insserv, early-boot SysV services | |
74 | (i.e. those for non-standard runlevels such as 'b' or 'S') | |
75 | or ArchLinux /etc/rc.conf support. We recommend the | |
76 | distributions who still need support this to either continue | |
77 | to maintain the necessary patches downstream, or find a | |
78 | different solution. (Talk to us if you have questions!) | |
79 | ||
80 | * Various systemd components will now bypass PolicyKit checks | |
81 | for root and otherwise handle properly if PolicyKit is not | |
82 | found to be around. This should fix most issues for | |
83 | PolicyKit-less systems. Quite frankly this should have been | |
84 | this way since day one. It is absolutely our intention to | |
85 | make systemd work fine on PolicyKit-less systems, and we | |
86 | consider it a bug if something doesn't work as it should if | |
87 | PolicyKit is not around. | |
88 | ||
89 | * For embedded systems it is now possible to build udev and | |
90 | systemd without blkid and/or kmod support. | |
91 | ||
92 | * "systemctl switch-root" is now capable of switching root | |
93 | more than once. I.e. in addition to transitions from the | |
94 | initrd to the host OS it is now possible to transition to | |
95 | further OS images from the host. This is useful to implement | |
96 | offline updating tools. | |
97 | ||
98 | * Various other additions have been made to the RPM macros | |
99 | shipped with systemd. Use %udev_rules_update() after | |
100 | installing new udev rules files. %_udevhwdbdir, | |
101 | %_udevrulesdir, %_journalcatalogdir, %_tmpfilesdir, | |
102 | %_sysctldir are now available which resolve to the right | |
103 | directories for packages to place various data files in. | |
104 | ||
105 | * journalctl gained the new --full switch (in addition to | |
106 | --all, to disable ellipsation for long messages. | |

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

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

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

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

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

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

437 | * Support for reading kernel messages from /proc/kmsg has now | |

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

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

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

b5b4c94a LP |
620 | CHANGES WITH 186: |
621 | ||
622 | * Several tools now understand kernel command line arguments, | |
623 | which are only read when run in an initial RAM disk. They | |
624 | usually follow closely their normal counterparts, but are | |
625 | prefixed with rd. | |
626 | ||
627 | * There's a new tool to analyze the readahead files that are | |
628 | automatically generated at boot. Use: | |
629 | ||
630 | /usr/lib/systemd/systemd-readahead analyze /.readahead | |
631 | ||
632 | * We now provide an early debug shell on tty9 if this enabled. Use: | |
633 | ||
d1f9edaf | 634 | systemctl enable debug-shell.service |
b5b4c94a LP |
635 | |
636 | * All plymouth related units have been moved into the Plymouth | |
637 | package. Please make sure to upgrade your Plymouth version | |
638 | as well. | |
639 | ||
640 | * systemd-tmpfiles now supports getting passed the basename of | |
641 | a configuration file only, in which case it will look for it | |
642 | in all appropriate directories automatically. | |
643 | ||
644 | * udevadm info now takes a /dev or /sys path as argument, and | |
645 | does the right thing. Example: | |
646 | ||
647 | udevadm info /dev/sda | |
648 | udevadm info /sys/class/block/sda | |
649 | ||
650 | * systemctl now prints a warning if a unit is stopped but a | |
651 | unit that might trigger it continues to run. Example: a | |
652 | service is stopped but the socket that activates it is left | |
653 | running. | |
654 | ||
655 | * "systemctl status" will now mention if the log output was | |
656 | shortened due to rotation since a service has been started. | |
657 | ||
658 | * The journal API now exposes functions to determine the | |
659 | "cutoff" times due to rotation. | |
660 | ||
661 | * journald now understands SIGUSR1 and SIGUSR2 for triggering | |
662 | immediately flushing of runtime logs to /var if possible, | |
663 | resp. for triggering immediate rotation of the journal | |
664 | files. | |
665 | ||
666 | * It is now considered an error if a service is attempted to | |
667 | be stopped that is not loaded. | |
668 | ||
669 | * XDG_RUNTIME_DIR now uses numeric UIDs instead of usernames. | |
670 | ||
671 | * systemd-analyze now supports Python 3 | |
672 | ||
673 | * tmpfiles now supports cleaning up directories via aging | |
674 | where the first level dirs are always kept around but | |
675 | directories beneath it automatically aged. This is enabled | |
676 | by prefixing the age field with '~'. | |
677 | ||
678 | * Seat objects now expose CanGraphical, CanTTY properties | |
679 | which is required to deal with very fast bootups where the | |
680 | display manager might be running before the graphics drivers | |
681 | completed initialization. | |
682 | ||
683 | * Seat objects now expose a State property. | |
684 | ||
685 | * We now include RPM macros for service enabling/disabling | |
686 | based on the preset logic. We recommend RPM based | |
687 | distributions to make use of these macros if possible. This | |
688 | makes it simpler to reuse RPM spec files across | |
689 | distributions. | |
690 | ||
691 | * We now make sure that the collected systemd unit name is | |
692 | always valid when services log to the journal via | |
693 | STDOUT/STDERR. | |
694 | ||
695 | * There's a new man page kernel-command-line(7) detailing all | |
696 | command line options we understand. | |
697 | ||
698 | * The fstab generator may now be disabled at boot by passing | |
699 | fstab=0 on the kernel command line. | |
700 | ||
91ac7425 | 701 | * A new kernel command line option modules-load= is now understood |
b5b4c94a LP |
702 | to load a specific kernel module statically, early at boot. |
703 | ||
704 | * Unit names specified on the systemctl command line are now | |
705 | automatically escaped as needed. Also, if file system or | |
706 | device paths are specified they are automatically turned | |
707 | into the appropriate mount or device unit names. Example: | |
708 | ||
709 | systemctl status /home | |
710 | systemctl status /dev/sda | |
711 | ||
712 | * The SysVConsole= configuration option has been removed from | |
713 | system.conf parsing. | |
714 | ||
715 | * The SysV search path is no longer exported on the D-Bus | |
716 | Manager object. | |
717 | ||
718 | * The Names= option is been removed from unit file parsing. | |
719 | ||
720 | * There's a new man page bootup(7) detailing the boot process. | |
721 | ||
722 | * Every unit and every generator we ship with systemd now | |
723 | comes with full documentation. The self-explanatory boot is | |
724 | complete. | |
725 | ||
726 | * A couple of services gained "systemd-" prefixes in their | |
727 | name if they wrap systemd code, rather than only external | |
728 | code. Among them fsck@.service which is now | |
729 | systemd-fsck@.service. | |
730 | ||
731 | * The HaveWatchdog property has been removed from the D-Bus | |
732 | Manager object. | |
733 | ||
734 | * systemd.confirm_spawn= on the kernel command line should now | |
735 | work sensibly. | |
736 | ||
737 | * There's a new man page crypttab(5) which details all options | |
738 | we actually understand. | |
739 | ||
740 | * systemd-nspawn gained a new --capability= switch to pass | |
741 | additional capabilities to the container. | |
742 | ||
743 | * timedated will now read known NTP implementation unit names | |
5b00c016 | 744 | from /usr/lib/systemd/ntp-units.d/*.list, |
b5b4c94a LP |
745 | systemd-timedated-ntp.target has been removed. |
746 | ||
747 | * journalctl gained a new switch "-b" that lists log data of | |
748 | the current boot only. | |
749 | ||
750 | * The notify socket is in the abstract namespace again, in | |
751 | order to support daemons which chroot() at start-up. | |
752 | ||
753 | * There is a new Storage= configuration option for journald | |
754 | which allows configuration of where log data should go. This | |
755 | also provides a way to disable journal logging entirely, so | |
756 | that data collected is only forwarded to the console, the | |
757 | kernel log buffer or another syslog implementation. | |
758 | ||

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

787 | * logind is now capable of (optionally) handling power and |
788 | sleep keys as well as the lid switch. | |
789 | ||
790 | * journalctl now understands the syntax "journalctl | |
791 | /usr/bin/avahi-daemon" to get all log output of a specific | |
792 | daemon. | |
793 | ||
794 | * CapabilityBoundingSet= in system.conf now also influences | |
795 | the capability bound set of usermode helpers of the kernel. | |

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

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

16f1239e | 990 | CHANGES WITH 44: |
b6a86739 | 991 | |
16f1239e LP |
992 | * This is mostly a bugfix release |
993 | ||
994 | * Support optional initialization of the machine ID from the | |
995 | KVM or container configured UUID. | |
996 | ||
997 | * Support immediate reboots with "systemctl reboot -ff" | |
998 | ||
999 | * Show /etc/os-release data in systemd-analyze output | |
1000 | ||
1001 | * Many bugfixes for the journal, including endianess fixes and | |
1002 | ensuring that disk space enforcement works | |
1003 | ||
1004 | * sd-login.h is C++ comptaible again | |
1005 | ||
1006 | * Extend the /etc/os-release format on request of the Debian | |
1007 | folks | |
1008 | ||
1009 | * We now refuse non-UTF8 strings used in various configuration | |
1010 | and unit files. This is done to ensure we don't pass invalid | |
1011 | data over D-Bus or expose it elsewhere. | |
1012 | ||
1013 | * Register Mimo USB Screens as suitable for automatic seat | |
1014 | configuration | |
1015 | ||
1016 | * Read SELinux client context from journal clients in a race | |
1017 | free fashion | |
1018 | ||
1019 | * Reorder configuration file lookup order. /etc now always | |
1020 | overrides /run in order to allow the administrator to always | |
1021 | and unconditionally override vendor supplied or | |
1022 | automatically generated data. | |
1023 | ||
1024 | * The various user visible bits of the journal now have man | |
1025 | pages. We still lack man pages for the journal API calls | |
1026 | however. | |
1027 | ||
1028 | * We now ship all man pages in HTML format again in the | |
1029 | tarball. | |

437b7dee LP |
1038 | * This is mostly a bugfix release |
1039 | ||
1040 | * systems lacking /etc/os-release are no longer supported. | |
1041 | ||
1042 | * Various functionality updates to libsystemd-login.so | |
1043 | ||
1044 | * Track class of PAM logins to distuingish greeters from | |
1045 | normal user logins. | |

b6a86739 | 1051 | |
204fa33c LP |
1052 | * This is an important bugfix release for v41. |
1053 | ||
1054 | * Building man pages is now optional which should be useful | |
1055 | for those building systemd from git but unwilling to install | |
1056 | xsltproc. | |
1057 | ||
1058 | * Watchdog support for supervising services is now usable. In | |
1059 | a future release support for hardware watchdogs | |
1060 | (i.e. /dev/watchdog) will be added building on this. | |
1061 | ||
1062 | * Service start rate limiting is now configurable and can be | |
1063 | turned off per service. When a start rate limit is hit a | |
1064 | reboot can automatically be triggered. | |
1065 | ||
1066 | * New CanReboot(), CanPowerOff() bus calls in systemd-logind. | |

e0d25329 | 1072 | CHANGES WITH 41: |
b6a86739 | 1073 | |
e0d25329 KS |
1074 | * The systemd binary is installed /usr/lib/systemd/systemd now; |
1075 | An existing /sbin/init symlink needs to be adapted with the | |
1076 | package update. | |
1077 | ||
b13df964 LP |
1078 | * The code that loads kernel modules has been ported to invoke |
1079 | libkmod directly, instead of modprobe. This means we do not | |
1080 | support systems with module-init-tools anymore. | |
1081 | ||
1082 | * Watchdog support is now already useful, but still not | |
1083 | complete. | |
1084 | ||
1085 | * A new kernel command line option systemd.setenv= is | |
1086 | understood to set system wide environment variables | |
1087 | dynamically at boot. | |
1088 | ||
ccd07a08 LP |
1089 | * We now limit the set of capabilities of systemd-journald. |
1090 | ||
353e12c2 LP |
1091 | * We now set SIGPIPE to ignore by default, since it only is |
1092 | useful in shell pipelines, and has little use in general | |
1093 | code. This can be disabled with IgnoreSIPIPE=no in unit | |
1094 | files. | |

b6a86739 | 1101 | |
d26e4270 LP |
1102 | * This is mostly a bugfix release |
1103 | ||
1104 | * We now expose the reason why a service failed in the | |
1105 | "Result" D-Bus property. | |
1106 | ||
1107 | * Rudimentary service watchdog support (will be completed over | |
1108 | the next few releases.) | |
1109 | ||
1110 | * When systemd forks off in order execute some service we will | |
1111 | now immediately changes its argv[0] to reflect which process | |
1112 | it will execute. This is useful to minimize the time window | |
1113 | with a generic argv[0], which makes bootcharts more useful | |

220a21d3 | 1119 | CHANGES WITH 39: |
b6a86739 | 1120 | |
220a21d3 LP |
1121 | * This is mostly a test release, but incorporates many |
1122 | bugfixes. | |
1123 | ||
1124 | * New systemd-cgtop tool to show control groups by their | |
1125 | resource usage. | |
1126 | ||
1127 | * Linking against libacl for ACLs is optional again. If | |
1128 | disabled, support tracking device access for active logins | |
1129 | goes becomes unavailable, and so does access to the user | |
1130 | journals by the respective users. | |
1131 | ||
1132 | * If a group "adm" exists, journal files are automatically | |
1133 | owned by them, thus allow members of this group full access | |
1134 | to the system journal as well as all user journals. | |
1135 | ||
1136 | * The journal now stores the SELinux context of the logging | |
1137 | client for all entries. | |
1138 | ||
1139 | * Add C++ inclusion guards to all public headers | |
1140 | ||
1141 | * New output mode "cat" in the journal to print only text | |
1142 | messages, without any meta data like date or time. | |
1143 | ||
1144 | * Include tiny X server wrapper as a temporary stop-gap to | |
1145 | teach XOrg udev display enumeration. This is used by display | |
1146 | managers such as gdm, and will go away as soon as XOrg | |
1147 | learned native udev hotplugging for display devices. | |
1148 | ||
1149 | * Add new systemd-cat tool for executing arbitrary programs | |
1150 | with STDERR/STDOUT connected to the journal. Can also act as | |
1151 | BSD logger replacement, and does so by default. | |
1152 | ||
1153 | * Optionally store all locally generated coredumps in the | |
1154 | journal along with meta data. | |
1155 | ||
1156 | * systemd-tmpfiles learnt four new commands: n, L, c, b, for | |
1157 | writing short strings to files (for usage for /sys), and for | |
1158 | creating symlinks, character and block device nodes. | |
1159 | ||
1160 | * New unit file option ControlGroupPersistent= to make cgroups | |
1161 | persistent, following the mechanisms outlined in | |
1162 | http://www.freedesktop.org/wiki/Software/systemd/PaxControlGroups | |
1163 | ||
1164 | * Support multiple local RTCs in a sane way | |
1165 | ||
1166 | * No longer monopolize IO when replaying readahead data on | |
1167 | rotating disks, since we might starve non-file-system IO to | |
1168 | death, since fanotify() will not see accesses done by blkid, | |
1169 | or fsck. | |
1170 | ||
1171 | * Don't show kernel threads in systemd-cgls anymore, unless | |
1172 | requested with new -k switch. | |

1177 | CHANGES WITH 38: | |
b6a86739 | 1178 | |
220a21d3 LP |
1179 | * This is mostly a test release, but incorporates many |
1180 | bugfixes. | |
1181 | ||
1182 | * The git repository moved to: | |
1183 | git://anongit.freedesktop.org/systemd/systemd | |
1184 | ssh://git.freedesktop.org/git/systemd/systemd | |
1185 | ||
1186 | * First release with the journal | |
1187 | http://0pointer.de/blog/projects/the-journal.html | |
1188 | ||
1189 | * The journal replaces both systemd-kmsg-syslogd and | |
1190 | systemd-stdout-bridge. | |
1191 | ||
1192 | * New sd_pid_get_unit() API call in libsystemd-logind | |
1193 | ||
1194 | * Many systemadm clean-ups | |
1195 | ||
1196 | * Introduce remote-fs-pre.target which is ordered before all | |
1197 | remote mounts and may be used to start services before all | |
1198 | remote mounts. | |
1199 | ||
1200 | * Added Mageia support | |
1201 | ||
1202 | * Add bash completion for systemd-loginctl | |
1203 | ||
1204 | * Actively monitor PID file creation for daemons which exit in | |
1205 | the parent process before having finished writing the PID | |
1206 | file in the daemon process. Daemons which do this need to be | |
1207 | fixed (i.e. PID file creation must have finished before the | |
1208 | parent exits), but we now react a bit more gracefully to them. | |
1209 | ||
1210 | * Add colourful boot output, mimicking the well-known output | |
1211 | of existing distributions. | |
1212 | ||
1213 | * New option PassCredentials= for socket units, for | |
1214 | compatibility with a recent kernel ABI breakage. | |
1215 | ||
1216 | * /etc/rc.local is now hooked in via a generator binary, and | |
1217 | thus will no longer act as synchronization point during | |
1218 | boot. | |
1219 | ||
1220 | * systemctl list-unit-files now supports --root=. | |
1221 | ||
1222 | * systemd-tmpfiles now understands two new commands: z, Z for | |
1223 | relabelling files according to the SELinux database. This is | |
1224 | useful to apply SELinux labels to specific files in /sys, | |
1225 | among other things. | |
1226 | ||
1227 | * Output of SysV services is now forwarded to both the console | |
1228 | and the journal by default, not only just the console. | |
1229 | ||
1230 | * New man pages for all APIs from libsystemd-login. | |
1231 | ||
1232 | * The build tree got reorganized and a the build system is a | |
1233 | lot more modular allowing embedded setups to specifically | |
1234 | select the components of systemd they are interested in. | |
1235 | ||
1236 | * Support for Linux systems lacking the kernel VT subsystem is | |
1237 | restored. | |
1238 | ||
1239 | * configure's --with-rootdir= got renamed to | |
1240 | --with-rootprefix= to follow the naming used by udev and | |
1241 | kmod | |
1242 | ||
1243 | * Unless specified otherwise we'll now install to /usr instead | |
1244 | of /usr/local by default. | |
1245 | ||
1246 | * Processes with '@' in argv[0][0] are now excluded from the | |
1247 | final shut-down killing spree, following the logic explained | |
1248 | in: | |
1249 | http://www.freedesktop.org/wiki/Software/systemd/RootStorageDaemons | |
1250 | ||
1251 | * All processes remaining in a service cgroup when we enter | |
1252 | the START or START_PRE states are now killed with | |
1253 | SIGKILL. That means it is no longer possible to spawn | |
1254 | background processes from ExecStart= lines (which was never | |
1255 | supported anyway, and bad style). | |
1256 | ||
1257 | * New PropagateReloadTo=/PropagateReloadFrom= options to bind | |
1258 | reloading of units together. | |
