3 | CHANGES WITH 198: |
4 | ||
5 | * Configuration of unit files may now be extended via drop-in | |
6 | files without having to edit/override the unit files | |
7 | themselves. More specifically, if the administrator wants to | |
8 | change one value for a service file foobar.service he can | |
9 | now do so by dropping in a configuration snippet into | |
10 | /etc/systemd/systemd/foobar.service.d/*.conf. The unit logic | |
11 | will load all these snippets and apply them on top of the | |
12 | main unit configuration file, possibly extending or | |
13 | overriding its settings. Using these drop-in snippets is | |
40e21da8 KS |
14 | generally nicer than the two earlier options for changing |
15 | unit files locally: copying the files from | |
85d68397 LP |
16 | /usr/lib/systemd/system/ to /etc/systemd/system/ and editing |
17 | them there; or creating a new file in /etc/systemd/system/ | |
18 | that incorporates the original one via ".include". Drop-in | |
19 | snippets into these .d/ directories can be placed in any | |
20 | directory systems looks for units in, and the usual | |
21 | overriding semantics between /usr/lib, /etc and /run apply | |
22 | for them too. | |
23 | ||
24 | * Most unit file settings which take lists of items can now be | |
25 | reset by assigning the empty strings to them. For example, | |
26 | normally, settings such as Environment=FOO=BAR append a new | |
27 | environment variable assignment to the environment block, | |
28 | each time they are used. By assigning Environment= the empty | |
29 | string the environment block can be reset to empty. This is | |
30 | particularly useful with the .d/*.conf drop-in snippets | |
31 | mentioned above, since this allows resetting list settings | |
32 | from vendor unit files via these drop-ins. | |
33 | ||
34 | * systemctl gained a new "list-dependencies" command for | |
35 | listing the dependencies of a unit recursively. | |
36 | ||
40e21da8 | 37 | * Inhibitors are now honored and listed by "systemctl |
85d68397 LP |
38 | suspend", "systemctl poweroff" (and similar) too, not only |
39 | GNOME. These commands will also list active sessions by | |
40 | other users. | |
41 | ||
42 | * Resource limits (as exposed by the various control group | |
43 | controllers) can now be controlled dynamically at runtime | |
44 | for all units. More specifically, you can now use a command | |
45 | like "systemctl set-cgroup-attr foobar.service cpu.shares | |
46 | 2000" to alter the CPU shares a specific service gets. These | |
47 | settings are stores persistently on disk, and thus allow the | |
48 | administrator to easily adjust the resource usage of | |
49 | services with a few simple commands. This dynamic resource | |
50 | management logic is also available to other services via the | |
51 | bus. Almost any kernel cgroup attribute and controller is | |
52 | supported. | |
53 | ||
54 | * systemd-vconsole-setup will now copy all font settings to | |
55 | all open VTs, where it previously applied them only to the | |
56 | foreground VT. | |
57 | ||
58 | * libsystemd-login gained the new sd_session_get_tty() API | |
59 | call. | |
60 | ||
61 | * This release drops support with a few | |
62 | legacy/distribution-specific LSB facility names when parsing | |
63 | init scripts: $x-display-manager, $mail-transfer-agent, | |
64 | $mail-transport-agent, $mail-transfer-agent, $smtp, | |
65 | $null. Also, the mail-transfer-agent.target unit backing | |
66 | this has been removed. Distributions which want to retain | |
67 | compatibility with this should carry the burden for support | |
68 | this themselves and patch support for these back in if they | |
69 | really need to. Also, the facilities $syslog and $local_fs | |
70 | are now ignored, since systemd does not support early-boot | |
71 | LSB init scripts anymore, and these facilities are implied | |
72 | anyway for normal services. syslog.target has also been | |
40e21da8 | 73 | removed. |
85d68397 | 74 | |
40e21da8 | 75 | * There are new bus calls on PID1's Manager object for |
85d68397 LP |
76 | canceling jobs, and removing snapshot units. Previously, |
77 | both calls were only available on the Job and Snapshot | |
78 | objects themselves. | |
79 | ||
80 | * systemd-journal-gatewayd gained SSL support. | |
81 | ||
82 | * The various "environment" files, such as /etc/locale.conf | |
83 | now support continuation lines with a backslash ("\") as | |
84 | last character in the line, similar in style (but different) | |
85 | to how this is supported in shells. | |
86 | ||
87 | * For normal user processes the _SYSTEMD_USER_UNIT= field is | |
88 | now implicitly appended to every log entry logged. systemctl | |
89 | has been updated to filter by this field when operating on a | |
90 | user systemd instance. | |
91 | ||
92 | * nspawn will now implicitly add the CAP_AUDIT_WRITE and | |
93 | CAP_AUDIT_CONTROL capabilities to the capabilities set for | |
94 | the container. This makes it easier to boot unmodified | |
95 | Fedora systems in a container, which however still requires | |
96 | audit=0 to be passed on the kernel command line. Auditing in | |
97 | kernel and userspace is unfortunately still too broken in | |
98 | context of containers, hence we recommend compiling it out | |
99 | of the kernel or using audit=0. Hopefully this will be fixed | |
100 | one day for good in the kernel. | |
101 | ||
102 | * nspawn gained the new --bind= and --bind-ro= parameters to | |
103 | bind mount specific directories from the host into the | |
104 | container. | |
105 | ||
40e21da8 KS |
106 | * nspawn will now mount its own devpts file system instance |
107 | into the container, in order not to leake pty devices from | |
85d68397 LP |
108 | the host into the container. |
109 | ||
110 | * systemd will now read the firmware boot time performance | |
111 | from the EFI variables, if the used boot loader supports | |
112 | this, and take it into account for boot performance analysis | |
113 | via "systemd-analyze". This is currently supported only in | |
114 | conjunction with Gummiboot, but could be supported by other | |
40e21da8 | 115 | boot loaders too. For details see: |
85d68397 LP |
116 | |
117 | http://www.freedesktop.org/wiki/Software/systemd/BootLoaderInterface | |
118 | ||
119 | * A new generator has been added that automatically mounts the | |
120 | EFI System Partition (ESP) to /boot, if that directory | |
121 | exists, is empty, and no other partition has been configured | |
122 | to be mounted there. | |
123 | ||
124 | * logind will now send out PrepareForSleep(false) out | |
125 | unconditionally, after coming back from suspend. This may be | |
126 | used by applications as asynchronous notification for | |
127 | system resume events. | |
128 | ||
129 | * "systemctl unlock-sessions" has been added, that allows | |
130 | unlocking the screens of all user sessions at once, similar | |
131 | how "systemctl lock-sessions" already locked all users | |
40e21da8 | 132 | sessions. This is backed by a new D-Bus call UnlockSessions(). |
85d68397 LP |
133 | |
134 | * "loginctl seat-status" will now show the master device of a | |
135 | seat. (i.e. the device of a seat that needs to be around for | |
136 | the seat to be considered available, usually the graphics | |
137 | card). | |
138 | ||
139 | * tmpfiles gained a new "X" line type, that allows | |
140 | configuration of files and directories (with wildcards) that | |
141 | shall be excluded from automatic cleanup ("aging"). | |
142 | ||
bf933560 KS |
143 | * udev default rules set the device node permissions now only |
144 | at "add" events, and do not change them any longer with a | |
145 | later "change" event. | |
85d68397 LP |
146 | |
147 | * The log messages for lid events and power/sleep keypresses | |
148 | now carry a message ID. | |
149 | ||
150 | * We now have a substantially larger unit test suite, but this | |
151 | continues to be work in progress. | |
152 | ||
153 | * udevadm hwdb gained a new --root= parameter to change the | |
154 | root directory to operate relative to. | |
155 | ||
40e21da8 KS |
156 | * logind will now issue a background sync() request to the kernel |
157 | early at shutdown, so that dirty buffers are flushed to disk early | |
85d68397 LP |
158 | instead of at the last moment, in order to optimize shutdown |
159 | times a little. | |
160 | ||
161 | * A new bootctl tool has been added that is an interface for | |
162 | certain boot loader operations. This is currently a preview | |
163 | and is likely to be extended into a small mechanism daemon | |
164 | like timedated, localed, hostnamed, and can be used by | |
165 | graphical UIs to enumerate available boot options, and | |
166 | request boot into firmware operations. | |
167 | ||
168 | * systemd-bootchart has been relicensed to LGPLv2.1+ to match | |
169 | the rest of the package. It also has been updated to work | |
170 | correctly in initrds. | |
171 | ||
172 | * Policykit previously has been runtime optional, and is now | |
173 | also compile time optional via a configure switch. | |
174 | ||
175 | * systemd-analyze has been reimplemented in C. Also "systemctl | |
176 | dot" has moved into systemd-analyze. | |
177 | ||
178 | * "systemctl status" with no further parameters will now print | |
179 | the status of all active or failed units. | |
180 | ||
181 | * Operations such as "systemctl start" can now be executed | |
182 | with a new mode "--irreversible" which may be used to queue | |
183 | operations that cannot accidentally be reversed by a later | |
184 | job queuing. This is by default use to make shutdown | |
185 | requests more robust. | |
186 | ||
187 | * The Python API of systemd now gained a new module for | |
188 | reading journal files. | |
189 | ||
190 | * A new tool kernel-install has been added that can install | |
191 | kernel images according to the Boot Loader Specification: | |
192 | ||
193 | http://www.freedesktop.org/wiki/Specifications/BootLoaderSpec | |
194 | ||
195 | * Boot time console output has been improved to provide | |
196 | animated boot time output. | |
197 | ||
198 | * A new tool systemd-activate has been added which can be used | |
199 | to test socket activation with, directly from the command | |
200 | line. This should make it much easier to test and debug | |
201 | socket activation in daemons. | |
202 | ||
203 | * journalctl gained a new "--reverse" (or -r) option to show | |
204 | journal output in reverse order (i.e. newest line first). | |
205 | ||
206 | * journalctl gained a new "--user-unit=" option, that works | |
207 | similar to "--unit=" but filters for user units rather than | |
208 | system units. | |
209 | ||
210 | * A number of unit files to ease adoption of systemd in | |
211 | initrds has been added. This moves some minimal logic from | |
212 | the various initrd implementations into systemd proper. | |
213 | ||
214 | * The journal files are now owned by a new group | |
215 | "systemd-journal", which exists specifically to allow access | |
216 | to the journal, and nothing else. Previously, we used the | |
217 | "adm" group for that, which however possible covers more | |
218 | than just journal/log file access. This new group is now | |
219 | already used by systemd-journal-gatewayd to ensure this | |
220 | daemon gets access to the journal files and as little else | |
221 | as possible. Note that "make install" will also set FS ACLs | |
222 | up for /var/log/journal to give "adm" and "wheel" read | |
223 | access to it, in addition to "systemd-journal" which owns | |
224 | the journal files. We recommend that packaging scripts also | |
225 | add read access to "adm", "wheel" to /var/log/journal, and | |
226 | all existing/future journal files. To normal users and | |
227 | administrators little changes, however packagers need to | |
228 | ensure to create the "systemd-journal" system group at | |
229 | package installation time. | |
230 | ||
231 | * The systemd-journal-gatewayd now runs as unprivileged user | |
232 | systemd-journal-gateway:systemd-journal-gateway. Packaging | |
233 | scripts need to create these system user/group at | |
234 | installation time. | |
235 | ||
236 | * timedated now exposes a new boolean property CanNTP that | |
237 | indicates whether a local NTP service is available or not. | |
238 | ||
239 | * systemd-detect-virt will now also detect xen PVs | |
240 | ||
40e21da8 KS |
241 | * The pstore file system is now mounted by default, if it is |
242 | available. | |
85d68397 | 243 | |
1aed4590 LP |
244 | * In addition to the SELinux and IMA policies we will now also |
245 | load SMACK policies at early boot. | |

262 | CHANGES WITH 197: |
263 | ||
264 | * Timer units now support calendar time events in addition to | |
265 | monotonic time events. That means you can now trigger a unit | |
266 | based on a calendar time specification such as "Thu,Fri | |
267 | 2013-*-1,5 11:12:13" which refers to 11:12:13 of the first | |
268 | or fifth day of any month of the year 2013, given that it is | |
269 | a thursday or friday. This brings timer event support | |
270 | considerably closer to cron's capabilities. For details on | |
271 | the supported calendar time specification language see | |
272 | systemd.time(7). | |
273 | ||
274 | * udev now supports a number of different naming policies for | |
275 | network interfaces for predictable names, and a combination | |
276 | of these policies is now the default. Please see this wiki | |
277 | document for details: | |
278 | ||
279 | http://www.freedesktop.org/wiki/Software/systemd/PredictableNetworkInterfaceNames | |
280 | ||
281 | * Auke Kok's bootchart implementation has been added to the | |
282 | systemd tree. It's an optional component that can graph the | |
283 | boot in quite some detail. It's one of the best bootchart | |
284 | implementations around and minimal in its code and | |
285 | dependencies. | |
286 | ||
287 | * nss-myhostname has been integrated into the systemd source | |
288 | tree. nss-myhostname guarantees that the local hostname | |
289 | always stays resolvable via NSS. It has been a weak | |
290 | requirement of systemd-hostnamed since a long time, and | |
291 | since its code is actually trivial we decided to just | |
292 | include it in systemd's source tree. It can be turned off | |
293 | with a configure switch. | |
294 | ||
295 | * The read-ahead logic is now capable of properly detecting | |
296 | whether a btrfs file system is on SSD or rotating media, in | |
297 | order to optimize the read-ahead scheme. Previously, it was | |
298 | only capable of detecting this on traditional file systems | |
299 | such as ext4. | |
300 | ||
301 | * In udev, additional device properties are now read from the | |
302 | IAB in addition to the OUI database. Also, Bluetooth company | |
303 | identities are attached to the devices as well. | |
304 | ||
305 | * In service files %U may be used as specifier that is | |
306 | replaced by the configured user name of the service. | |
307 | ||
308 | * nspawn may now be invoked without a controlling TTY. This | |
309 | makes it suitable for invocation as its own service. This | |
310 | may be used to set up a simple containerized server system | |
311 | using only core OS tools. | |
312 | ||
313 | * systemd and nspawn can now accept socket file descriptors | |
314 | when they are started for socket activation. This enables | |
315 | implementation of socket activated nspawn | |
316 | containers. i.e. think about autospawning an entire OS image | |
317 | when the first SSH or HTTP connection is received. We expect | |
318 | that similar functionality will also be added to libvirt-lxc | |
319 | eventually. | |
320 | ||
321 | * journalctl will now suppress ANSI color codes when | |
322 | presenting log data. | |
323 | ||
324 | * systemctl will no longer show control group information for | |
325 | a unit if a the control group is empty anyway. | |
326 | ||
327 | * logind can now automatically suspend/hibernate/shutdown the | |
328 | system on idle. | |
329 | ||
330 | * /etc/machine-info and hostnamed now also expose the chassis | |
331 | type of the system. This can be used to determine whether | |
332 | the local system is a laptop, desktop, handset or | |
333 | tablet. This information may either be configured by the | |
334 | user/vendor or is automatically determined from ACPI and DMI | |
335 | information if possible. | |
336 | ||
337 | * A number of PolicyKit actions are now bound together with | |
338 | "imply" rules. This should simplify creating UIs because | |
339 | many actions will now authenticate similar ones as well. | |
340 | ||
341 | * Unit files learnt a new condition ConditionACPower= which | |
342 | may be used to conditionalize a unit depending on whether an | |
343 | AC power source is connected or not, of whether the system | |
344 | is running on battery power. | |
345 | ||
346 | * systemctl gained a new "is-failed" verb that may be used in | |
347 | shell scripts and suchlike to check whether a specific unit | |
348 | is in the "failed" state. | |
349 | ||
350 | * The EnvironmentFile= setting in unit files now supports file | |
351 | globbing, and can hence be used to easily read a number of | |
352 | environment files at once. | |
353 | ||
354 | * systemd will no longer detect and recognize specific | |
355 | distributions. All distribution-specific #ifdeffery has been | |
356 | removed, systemd is now fully generic and | |
357 | distribution-agnostic. Effectively, not too much is lost as | |
358 | a lot of the code is still accessible via explicit configure | |
359 | switches. However, support for some distribution specific | |
360 | legacy configuration file formats has been dropped. We | |
361 | recommend distributions to simply adopt the configuration | |
362 | files everybody else uses now and convert the old | |
363 | configuration from packaging scripts. Most distributions | |
364 | already did that. If that's not possible or desirable, | |
365 | distributions are welcome to forward port the specific | |
366 | pieces of code locally from the git history. | |
367 | ||
368 | * When logging a message about a unit systemd will now always | |
369 | log the unit name in the message meta data. | |
370 | ||
371 | * localectl will now also discover system locale data that is | |
372 | not stored in locale archives, but directly unpacked. | |
373 | ||
374 | * logind will no longer unconditionally use framebuffer | |
375 | devices as seat masters, i.e. as devices that are required | |
376 | to be existing before a seat is considered preset. Instead, | |
377 | it will now look for all devices that are tagged as | |
378 | "seat-master" in udev. By default framebuffer devices will | |
379 | be marked as such, but depending on local systems other | |
380 | devices might be marked as well. This may be used to | |
381 | integrate graphics cards using closed source drivers (such | |
382 | as NVidia ones) more nicely into logind. Note however, that | |
383 | we recommend using the open source NVidia drivers instead, | |
384 | and no udev rules for the closed-source drivers will be | |
385 | shipped from us upstream. | |

0428ddb7 LP |
401 | CHANGES WITH 196: |
402 | ||
403 | * udev gained support for loading additional device properties | |
404 | from an indexed database that is keyed by vendor/product IDs | |
405 | and similar device identifiers. For the beginning this | |
406 | "hwdb" is populated with data from the well-known PCI and | |
407 | USB database, but also includes PNP, ACPI and OID data. In | |
408 | the longer run this indexed database shall grow into | |
409 | becoming the one central database for non-essential | |
410 | userspace device metadata. Previously, data from the PCI/USB | |
96ec33c0 | 411 | database was only attached to select devices, since the |
0428ddb7 | 412 | lookup was a relatively expensive operation due to O(n) time |
96ec33c0 LP |
413 | complexity (with n being the number of entries in the |
414 | database). Since this is now O(1), we decided to add in this | |
415 | data for all devices where this is available, by | |
0428ddb7 LP |
416 | default. Note that the indexed database needs to be rebuilt |
417 | when new data files are installed. To achieve this you need | |
418 | to update your packaging scripts to invoke "udevadm hwdb | |
419 | --update" after installation of hwdb data files. For | |
420 | RPM-based distributions we introduced the new | |
421 | %udev_hwdb_update macro for this purpose. | |
422 | ||
423 | * The Journal gained support for the "Message Catalog", an | |
424 | indexed database to link up additional information with | |
425 | journal entries. For further details please check: | |
426 | ||
427 | http://www.freedesktop.org/wiki/Software/systemd/catalog | |
428 | ||
429 | The indexed message catalog database also needs to be | |
430 | rebuilt after installation of message catalog files. Use | |
431 | "journalctl --update-catalog" for this. For RPM-based | |
432 | distributions we introduced the %journal_catalog_update | |
433 | macro for this purpose. | |
434 | ||
435 | * The Python Journal bindings gained support for the standard | |
436 | Python logging framework. | |
437 | ||
438 | * The Journal API gained new functions for checking whether | |
439 | the underlying file system of a journal file is capable of | |
440 | properly reporting file change notifications, or whether | |
441 | applications that want to reflect journal changes "live" | |
442 | need to recheck journal files continously in appropriate | |
443 | time intervals. | |
444 | ||
445 | * It is now possible to set the "age" field for tmpfiles | |
446 | entries to 0, indicating that files matching this entry | |
447 | shall always be removed when the directories are cleaned up. | |
448 | ||
449 | * coredumpctl gained a new "gdb" verb which invokes gdb | |
450 | right-away on the selected coredump. | |
451 | ||
452 | * There's now support for "hybrid sleep" on kernels that | |
453 | support this, in addition to "suspend" and "hibernate". Use | |
454 | "systemctl hybrid-sleep" to make use of this. | |
455 | ||
456 | * logind's HandleSuspendKey= setting (and related settings) | |
457 | now gained support for a new "lock" setting to simply | |
458 | request the screen lock on all local sessions, instead of | |
459 | actually executing a suspend or hibernation. | |
460 | ||
461 | * systemd will now mount the EFI variables file system by | |
462 | default. | |
463 | ||
464 | * Socket units now gained support for configuration of the | |
465 | SMACK security label. | |
466 | ||
467 | * timedatectl will now output the time of the last and next | |
468 | daylight saving change. | |
469 | ||
470 | * We dropped support for various legacy and distro-specific | |
471 | concepts, such as insserv, early-boot SysV services | |
472 | (i.e. those for non-standard runlevels such as 'b' or 'S') | |
473 | or ArchLinux /etc/rc.conf support. We recommend the | |
474 | distributions who still need support this to either continue | |
475 | to maintain the necessary patches downstream, or find a | |
476 | different solution. (Talk to us if you have questions!) | |
477 | ||
478 | * Various systemd components will now bypass PolicyKit checks | |
479 | for root and otherwise handle properly if PolicyKit is not | |
480 | found to be around. This should fix most issues for | |
481 | PolicyKit-less systems. Quite frankly this should have been | |
482 | this way since day one. It is absolutely our intention to | |
483 | make systemd work fine on PolicyKit-less systems, and we | |
484 | consider it a bug if something doesn't work as it should if | |
485 | PolicyKit is not around. | |
486 | ||
487 | * For embedded systems it is now possible to build udev and | |
488 | systemd without blkid and/or kmod support. | |
489 | ||
490 | * "systemctl switch-root" is now capable of switching root | |
491 | more than once. I.e. in addition to transitions from the | |
492 | initrd to the host OS it is now possible to transition to | |
493 | further OS images from the host. This is useful to implement | |
494 | offline updating tools. | |
495 | ||
496 | * Various other additions have been made to the RPM macros | |
497 | shipped with systemd. Use %udev_rules_update() after | |
498 | installing new udev rules files. %_udevhwdbdir, | |
499 | %_udevrulesdir, %_journalcatalogdir, %_tmpfilesdir, | |
500 | %_sysctldir are now available which resolve to the right | |
501 | directories for packages to place various data files in. | |
502 | ||
503 | * journalctl gained the new --full switch (in addition to | |
504 | --all, to disable ellipsation for long messages. | |

516 | CHANGES WITH 195: |
517 | ||
6827101a | 518 | * journalctl gained new --since= and --until= switches to |
139ee8cc LP |
519 | filter by time. It also now supports nice filtering for |
520 | units via --unit=/-u. | |
521 | ||
6827101a | 522 | * Type=oneshot services may use ExecReload= and do the |
139ee8cc LP |
523 | right thing. |
524 | ||
525 | * The journal daemon now supports time-based rotation and | |
526 | vacuuming, in addition to the usual disk-space based | |
527 | rotation. | |
528 | ||
529 | * The journal will now index the available field values for | |
530 | each field name. This enables clients to show pretty drop | |
531 | downs of available match values when filtering. The bash | |
532 | completion of journalctl has been updated | |
533 | accordingly. journalctl gained a new switch -F to list all | |
534 | values a certain field takes in the journal database. | |
535 | ||
536 | * More service events are now written as structured messages | |
537 | to the journal, and made recognizable via message IDs. | |
538 | ||
539 | * The timedated, localed and hostnamed mini-services which | |
540 | previously only provided support for changing time, locale | |
541 | and hostname settings from graphical DEs such as GNOME now | |
542 | also have a minimal (but very useful) text-based client | |
543 | utility each. This is probably the nicest way to changing | |
544 | these settings from the command line now, especially since | |
545 | it lists available options and is fully integrated with bash | |
546 | completion. | |
547 | ||
548 | * There's now a new tool "systemd-coredumpctl" to list and | |
549 | extract coredumps from the journal. | |
550 | ||
551 | * We now install a README each in /var/log/ and | |
552 | /etc/rc.d/init.d explaining where the system logs and init | |
553 | scripts went. This hopefully should help folks who go to | |
554 | that dirs and look into the otherwise now empty void and | |
555 | scratch their heads. | |
556 | ||
557 | * When user-services are invoked (by systemd --user) the | |
558 | $MANAGERPID env var is set to the PID of systemd. | |
559 | ||
560 | * SIGRTMIN+24 when sent to a --user instance will now result | |
561 | in immediate termination of systemd. | |
562 | ||
563 | * gatewayd received numerous feature additions such as a | |
564 | "follow" mode, for live syncing and filtering. | |
565 | ||
566 | * browse.html now allows filtering and showing detailed | |
567 | information on specific entries. Keyboard navigation and | |
568 | mouse screen support has been added. | |
569 | ||
570 | * gatewayd/journalctl now supports HTML5/JSON | |
571 | Server-Sent-Events as output. | |
572 | ||
1cb88f2c | 573 | * The SysV init script compatibility logic will now |
139ee8cc LP |
574 | heuristically determine whether a script supports the |
575 | "reload" verb, and only then make this available as | |
576 | "systemctl reload". | |
577 | ||
15f47220 | 578 | * "systemctl status --follow" has been removed, use "journalctl |
139ee8cc LP |
579 | -u" instead. |
580 | ||
581 | * journald.conf's RuntimeMinSize=, PersistentMinSize= settings | |
582 | have been removed since they are hardly useful to be | |
583 | configured. | |
584 | ||
585 | * And I'd like to take the opportunity to specifically mention | |
586 | Zbigniew for his great contributions. Zbigniew, you rock! | |

596 | CHANGES WITH 194: |
597 | ||
598 | * If /etc/vconsole.conf is non-existent or empty we will no | |
599 | longer load any console font or key map at boot by | |
600 | default. Instead the kernel defaults will be left | |
601 | intact. This is definitely the right thing to do, as no | |
602 | configuration should mean no configuration, and hard-coding | |
603 | font names that are different on all archs is probably a bad | |
604 | idea. Also, the kernel default key map and font should be | |
605 | good enough for most cases anyway, and mostly identical to | |
606 | the userspace fonts/key maps we previously overloaded them | |
607 | with. If distributions want to continue to default to a | |
608 | non-kernel font or key map they should ship a default | |
609 | /etc/vconsole.conf with the appropriate contents. | |

615 | CHANGES WITH 193: |
616 | ||
617 | * journalctl gained a new --cursor= switch to show entries | |
618 | starting from the specified location in the journal. | |
619 | ||
620 | * We now enforce a size limit on journal entry fields exported | |
621 | with "-o json" in journalctl. Fields larger than 4K will be | |
622 | assigned null. This can be turned off with --all. | |
623 | ||
624 | * An (optional) journal gateway daemon is now available as | |
625 | "systemd-journal-gatewayd.service". This service provides | |
626 | access to the journal via HTTP and JSON. This functionality | |
627 | will be used to implement live log synchronization in both | |
628 | pull and push modes, but has various other users too, such | |
629 | as easy log access for debugging of embedded devices. Right | |
630 | now it is already useful to retrieve the journal via HTTP: | |
631 | ||
632 | # systemctl start systemd-journal-gatewayd.service | |
633 | # wget http://localhost:19531/entries | |
634 | ||
635 | This will download the journal contents in a | |
636 | /var/log/messages compatible format. The same as JSON: | |
637 | ||
638 | # curl -H"Accept: application/json" http://localhost:19531/entries | |
639 | ||
640 | This service is also accessible via a web browser where a | |
641 | single static HTML5 app is served that uses the JSON logic | |
642 | to enable the user to do some basic browsing of the | |
643 | journal. This will be extended later on. Here's an example | |
644 | screenshot of this app in its current state: | |

651 | CHANGES WITH 192: |
652 | ||
653 | * The bash completion logic is now available for journalctl | |
654 | too. | |
655 | ||
656 | * We don't mount the "cpuset" controller anymore together with | |
657 | "cpu" and "cpuacct", as "cpuset" groups generally cannot be | |
658 | started if no parameters are assigned to it. "cpuset" hence | |
659 | broke code that assumed it it could create "cpu" groups and | |
660 | just start them. | |
661 | ||
662 | * journalctl -f will now subscribe to terminal size changes, | |
663 | and line break accordingly. | |

668 | CHANGES WITH 191: |
669 | ||
670 | * nspawn will now create a symlink /etc/localtime in the | |
671 | container environment, copying the host's timezone | |
672 | setting. Previously this has been done via a bind mount, but | |
673 | since symlinks cannot be bind mounted this has now been | |
674 | changed to create/update the appropriate symlink. | |
675 | ||
676 | * journalctl -n's line number argument is now optional, and | |
677 | will default to 10 if omitted. | |
678 | ||
679 | * journald will now log the maximum size the journal files may | |
680 | take up on disk. This is particularly useful if the default | |
681 | built-in logic of determining this parameter from the file | |
682 | system size is used. Use "systemctl status | |
6563b535 | 683 | systemd-journald.service" to see this information. |
b6a86739 LP |
684 | |
685 | * The multi-seat X wrapper tool has been stripped down. As X | |
686 | is now capable of enumerating graphics devices via udev in a | |
687 | seat-aware way the wrapper is not strictly necessary | |
688 | anymore. A stripped down temporary stop-gap is still shipped | |
689 | until the upstream display managers have been updated to | |
690 | fully support the new X logic. Expect this wrapper to be | |
6563b535 | 691 | removed entirely in one of the next releases. |
b6a86739 LP |
692 | |
693 | * HandleSleepKey= in logind.conf has been split up into | |
694 | HandleSuspendKey= and HandleHibernateKey=. The old setting | |
6563b535 | 695 | is not available anymore. X11 and the kernel are |
b6a86739 LP |
696 | distuingishing between these keys and we should too. This |
697 | also means the inhibition lock for these keys has been split | |
698 | into two. | |

0c11f949 LP |
703 | CHANGES WITH 190: |
704 | ||
705 | * Whenever a unit changes state we'll now log this to the | |
706 | journal and show along the unit's own log output in | |
707 | "systemctl status". | |
708 | ||
709 | * ConditionPathIsMountPoint= can now properly detect bind | |
710 | mount points too. (Previously, a bind mount of one file | |
8d0256b7 | 711 | system to another place in the same file system could not be |
0c11f949 LP |
712 | detected as mount, since they shared struct stat's st_dev |
713 | field.) | |
714 | ||
715 | * We will now mount the cgroup controllers cpu, cpuacct, | |
716 | cpuset and the controllers net_cls, net_prio together by | |
717 | default. | |
718 | ||
719 | * nspawn containers will now have a virtualized boot | |
720 | ID. (i.e. /proc/sys/kernel/random/boot_id is now mounted | |
721 | over with a randomized ID at container initialization). This | |
722 | has the effect of making "journalctl -b" do the right thing | |
723 | in a container. | |
724 | ||
725 | * The JSON output journal serialization has been updated not | |
726 | to generate "endless" list objects anymore, but rather one | |
727 | JSON object per line. This is more in line how most JSON | |
728 | parsers expect JSON objects. The new output mode | |
729 | "json-pretty" has been added to provide similar output, but | |
730 | neatly aligned for readability by humans. | |
731 | ||
732 | * We dropped all explicit sync() invocations in the shutdown | |
733 | code. The kernel does this implicitly anyway in the kernel | |
734 | reboot() syscall. halt(8)'s -n option is now a compatibility | |
735 | no-op. | |
736 | ||
737 | * We now support virtualized reboot() in containers, as | |
738 | supported by newer kernels. We will fall back to exit() if | |
739 | CAP_SYS_REBOOT is not available to the container. Also, | |
740 | nspawn makes use of this now and will actually reboot the | |
741 | container if the containerized OS asks for that. | |
742 | ||
743 | * journalctl will only show local log output by default | |
744 | now. Use --merge (-m) to show remote log output, too. | |
745 | ||
746 | * libsystemd-journal gained the new sd_journal_get_usage() | |
747 | call to determine the current disk usage of all journal | |
748 | files. This is exposed in the new "journalctl --disk-usage" | |
749 | command. | |
750 | ||
751 | * journald gained a new configuration setting SplitMode= in | |
752 | journald.conf which may be used to control how user journals | |
753 | are split off. See journald.conf(5) for details. | |
754 | ||
755 | * A new condition type ConditionFileNotEmpty= has been added. | |
756 | ||
757 | * tmpfiles' "w" lines now support file globbing, to write | |
758 | multiple files at once. | |
759 | ||
760 | * We added Python bindings for the journal submission | |
761 | APIs. More Python APIs for a number of selected APIs will | |
762 | likely follow. Note that we intend to add native bindings | |
763 | only for the Python language, as we consider it common | |
764 | enough to deserve bindings shipped within systemd. There are | |
765 | various projects outside of systemd that provide bindings | |
766 | for languages such as PHP or Lua. | |
767 | ||
a98d5d64 LP |
768 | * Many conditions will now resolve specifiers such as %i. In |
769 | addition, PathChanged= and related directives of .path units | |
770 | now support specifiers as well. | |
0c11f949 LP |
771 | |
772 | * There's now a new RPM macro definition for the system preset | |
773 | dir: %_presetdir. | |
774 | ||
775 | * journald will now warn if it can't foward a message to the | |
776 | syslog daemon because it's socket is full. | |
777 | ||
778 | * timedated will no longer write or process /etc/timezone, | |
779 | except on Debian. As we do not support late mounted /usr | |
780 | anymore /etc/localtime always being a symlink is now safe, | |
781 | and hence the information in /etc/timezone is not necessary | |
782 | anymore. | |
783 | ||
aaccc32c | 784 | * logind will now always reserve one VT for a text getty (VT6 |
0c11f949 LP |
785 | by default). Previously if more than 6 X sessions where |
786 | started they took up all the VTs with auto-spawned gettys, | |
787 | so that no text gettys were available anymore. | |
788 | ||
789 | * udev will now automatically inform the btrfs kernel logic | |
790 | about btrfs RAID components showing up. This should make | |
791 | simple hotplug based btrfs RAID assembly work. | |
792 | ||
793 | * PID 1 will now increase its RLIMIT_NOFILE to 64K by default | |
794 | (but not for its children which will stay at the kernel | |
795 | default). This should allow setups with a lot more listening | |
796 | sockets. | |
797 | ||
798 | * systemd will now always pass the configured timezone to the | |
799 | kernel at boot. timedated will do the same when the timezone | |
800 | is changed. | |
801 | ||
802 | * logind's inhibition logic has been updated. By default, | |
803 | logind will now handle the lid switch, the power and sleep | |
804 | keys all the time, even in graphical sessions. If DEs want | |
805 | to handle these events on their own they should take the new | |
806 | handle-power-key, handle-sleep-key and handle-lid-switch | |
807 | inhibitors during their runtime. A simple way to achiveve | |
808 | that is to invoke the DE wrapped in an invocation of: | |
809 | ||
810 | systemd-inhibit --what=handle-power-key:handle-sleep-key:handle-lid-switch ... | |
811 | ||
812 | * Access to unit operations is now checked via SELinux taking | |
813 | the unit file label and client process label into account. | |
814 | ||
aad803af LP |
815 | * systemd will now notify the administrator in the journal |
816 | when he over-mounts a non-empty directory. | |
817 | ||
818 | * There are new specifiers that are resolved in unit files, | |
819 | for the host name (%H), the machine ID (%m) and the boot ID | |
820 | (%b). | |

830 | CHANGES WITH 189: |
831 | ||
832 | * Support for reading structured kernel messages from | |
833 | /dev/kmsg has now been added and is enabled by default. | |
834 | ||
835 | * Support for reading kernel messages from /proc/kmsg has now | |
836 | been removed. If you want kernel messages in the journal | |
837 | make sure to run a recent kernel (>= 3.5) that supports | |
838 | reading structured messages from /dev/kmsg (see | |
839 | above). /proc/kmsg is now exclusive property of classic | |
840 | syslog daemons again. | |
841 | ||
842 | * The libudev API gained the new | |
843 | udev_device_new_from_device_id() call. | |
844 | ||
845 | * The logic for file system namespace (ReadOnlyDirectory=, | |
846 | ReadWriteDirectoy=, PrivateTmp=) has been reworked not to | |
847 | require pivot_root() anymore. This means fewer temporary | |
848 | directories are created below /tmp for this feature. | |
849 | ||
850 | * nspawn containers will now see and receive all submounts | |
851 | made on the host OS below the root file system of the | |
852 | container. | |
853 | ||
854 | * Forward Secure Sealing is now supported for Journal files, | |
855 | which provide cryptographical sealing of journal files so | |
856 | that attackers cannot alter log history anymore without this | |
857 | being detectable. Lennart will soon post a blog story about | |
858 | this explaining it in more detail. | |
859 | ||
860 | * There are two new service settings RestartPreventExitStatus= | |
861 | and SuccessExitStatus= which allow configuration of exit | |
862 | status (exit code or signal) which will be excepted from the | |
863 | restart logic, resp. consider successful. | |
864 | ||
865 | * journalctl gained the new --verify switch that can be used | |
866 | to check the integrity of the structure of journal files and | |
867 | (if Forward Secure Sealing is enabled) the contents of | |
868 | journal files. | |
869 | ||
870 | * nspawn containers will now be run with /dev/stdin, /dev/fd/ | |
871 | and similar symlinks pre-created. This makes running shells | |
872 | as container init process a lot more fun. | |
873 | ||
874 | * The fstab support can now handle PARTUUID= and PARTLABEL= | |
875 | entries. | |
876 | ||
877 | * A new ConditionHost= condition has been added to match | |
878 | against the hostname (with globs) and machine ID. This is | |
879 | useful for clusters where a single OS image is used to | |
880 | provision a large number of hosts which shall run slightly | |
881 | different sets of services. | |
882 | ||
883 | * Services which hit the restart limit will now be placed in a | |
884 | failure state. | |

890 | CHANGES WITH 188: |
891 | ||
892 | * When running in --user mode systemd will now become a | |
893 | subreaper (PR_SET_CHILD_SUBREAPER). This should make the ps | |
894 | tree a lot more organized. | |
895 | ||
896 | * A new PartOf= unit dependency type has been introduced that | |
897 | may be used to group services in a natural way. | |
898 | ||
899 | * "systemctl enable" may now be used to enable instances of | |
900 | services. | |
901 | ||
902 | * journalctl now prints error log levels in red, and | |
903 | warning/notice log levels in bright white. It also supports | |
904 | filtering by log level now. | |
905 | ||
906 | * cgtop gained a new -n switch (similar to top), to configure | |
907 | the maximum number of iterations to run for. It also gained | |
908 | -b, to run in batch mode (accepting no input). | |
909 | ||
910 | * The suffix ".service" may now be ommited on most systemctl | |
911 | command lines involving service unit names. | |
912 | ||
913 | * There's a new bus call in logind to lock all sessions, as | |
914 | well as a loginctl verb for it "lock-sessions". | |
915 | ||
916 | * libsystemd-logind.so gained a new call sd_journal_perror() | |
917 | that works similar to libc perror() but logs to the journal | |
918 | and encodes structured information about the error number. | |
919 | ||
920 | * /etc/crypttab entries now understand the new keyfile-size= | |
921 | option. | |
922 | ||
923 | * shutdown(8) now can send a (configurable) wall message when | |
924 | a shutdown is cancelled. | |
925 | ||
926 | * The mount propagation mode for the root file system will now | |
927 | default to "shared", which is useful to make containers work | |
928 | nicely out-of-the-box so that they receive new mounts from | |
929 | the host. This can be undone locally by running "mount | |
930 | --make-rprivate /" if needed. | |
931 | ||
932 | * The prefdm.service file has been removed. Distributions | |
933 | should maintain this unit downstream if they intend to keep | |
934 | it around. However, we recommend writing normal unit files | |
935 | for display managers instead. | |
936 | ||
937 | * Since systemd is a crucial part of the OS we will now | |
938 | default to a number of compiler switches that improve | |
939 | security (hardening) such as read-only relocations, stack | |
940 | protection, and suchlike. | |
941 | ||
942 | * The TimeoutSec= setting for services is now split into | |
943 | TimeoutStartSec= and TimeoutStopSec= to allow configuration | |
944 | of individual time outs for the start and the stop phase of | |
945 | the service. | |

c4f1b862 LP |
954 | CHANGES WITH 187: |
955 | ||
956 | * The journal and id128 C APIs are now fully documented as man | |
957 | pages. | |
958 | ||
959 | * Extra safety checks have been added when transitioning from | |
960 | the initial RAM disk to the main system to avoid accidental | |
961 | data loss. | |
962 | ||
c269cec3 | 963 | * /etc/crypttab entries now understand the new keyfile-offset= |
c4f1b862 LP |
964 | option. |
965 | ||
966 | * systemctl -t can now be used to filter by unit load state. | |
967 | ||
968 | * The journal C API gained the new sd_journal_wait() call to | |
969 | make writing synchronous journal clients easier. | |
970 | ||
971 | * journalctl gained the new -D switch to show journals from a | |
972 | specific directory. | |
973 | ||
974 | * journalctl now displays a special marker between log | |
975 | messages of two different boots. | |
976 | ||
977 | * The journal is now explicitly flushed to /var via a service | |
978 | systemd-journal-flush.service, rather than implicitly simply | |
979 | by seeing /var/log/journal to be writable. | |
980 | ||
981 | * journalctl (and the journal C APIs) can now match for much | |
982 | more complex expressions, with alternatives and | |
983 | disjunctions. | |
984 | ||
985 | * When transitioning from the initial RAM disk to the main | |
986 | system we will now kill all processes in a killing spree to | |
987 | ensure no processes stay around by accident. | |
988 | ||
989 | * Three new specifiers may be used in unit files: %u, %h, %s | |
990 | resolve to the user name, user home directory resp. user | |
991 | shell. This is useful for running systemd user instances. | |
992 | ||
993 | * We now automatically rotate journal files if their data | |
994 | object hash table gets a fill level > 75%. We also size the | |
995 | hash table based on the configured maximum file size. This | |
996 | together should lower hash collisions drastically and thus | |
997 | speed things up a bit. | |
998 | ||
999 | * journalctl gained the new "--header" switch to introspect | |
1000 | header data of journal files. | |
1001 | ||
1002 | * A new setting SystemCallFilters= has been added to services | |
1003 | which may be used to apply blacklists or whitelists to | |
1004 | system calls. This is based on SECCOMP Mode 2 of Linux 3.5. | |
1005 | ||
1006 | * nspawn gained a new --link-journal= switch (and quicker: -j) | |
1007 | to link the container journal with the host. This makes it | |
1008 | very easy to centralize log viewing on the host for all | |
1009 | guests while still keeping the journal files separated. | |
1010 | ||
1011 | * Many bugfixes and optimizations | |

b5b4c94a LP |
1018 | CHANGES WITH 186: |
1019 | ||
1020 | * Several tools now understand kernel command line arguments, | |
1021 | which are only read when run in an initial RAM disk. They | |
1022 | usually follow closely their normal counterparts, but are | |
1023 | prefixed with rd. | |
1024 | ||
1025 | * There's a new tool to analyze the readahead files that are | |
1026 | automatically generated at boot. Use: | |
1027 | ||
1028 | /usr/lib/systemd/systemd-readahead analyze /.readahead | |
1029 | ||
1030 | * We now provide an early debug shell on tty9 if this enabled. Use: | |
1031 | ||
d1f9edaf | 1032 | systemctl enable debug-shell.service |
b5b4c94a LP |
1033 | |
1034 | * All plymouth related units have been moved into the Plymouth | |
1035 | package. Please make sure to upgrade your Plymouth version | |
1036 | as well. | |
1037 | ||
1038 | * systemd-tmpfiles now supports getting passed the basename of | |
1039 | a configuration file only, in which case it will look for it | |
1040 | in all appropriate directories automatically. | |
1041 | ||
1042 | * udevadm info now takes a /dev or /sys path as argument, and | |
1043 | does the right thing. Example: | |
1044 | ||
1045 | udevadm info /dev/sda | |
1046 | udevadm info /sys/class/block/sda | |
1047 | ||
1048 | * systemctl now prints a warning if a unit is stopped but a | |
1049 | unit that might trigger it continues to run. Example: a | |
1050 | service is stopped but the socket that activates it is left | |
1051 | running. | |
1052 | ||
1053 | * "systemctl status" will now mention if the log output was | |
1054 | shortened due to rotation since a service has been started. | |
1055 | ||
1056 | * The journal API now exposes functions to determine the | |
1057 | "cutoff" times due to rotation. | |
1058 | ||
1059 | * journald now understands SIGUSR1 and SIGUSR2 for triggering | |
1060 | immediately flushing of runtime logs to /var if possible, | |
1061 | resp. for triggering immediate rotation of the journal | |
1062 | files. | |
1063 | ||
1064 | * It is now considered an error if a service is attempted to | |
1065 | be stopped that is not loaded. | |
1066 | ||
1067 | * XDG_RUNTIME_DIR now uses numeric UIDs instead of usernames. | |
1068 | ||
1069 | * systemd-analyze now supports Python 3 | |
1070 | ||
1071 | * tmpfiles now supports cleaning up directories via aging | |
1072 | where the first level dirs are always kept around but | |
1073 | directories beneath it automatically aged. This is enabled | |
1074 | by prefixing the age field with '~'. | |
1075 | ||
1076 | * Seat objects now expose CanGraphical, CanTTY properties | |
1077 | which is required to deal with very fast bootups where the | |
1078 | display manager might be running before the graphics drivers | |
1079 | completed initialization. | |
1080 | ||
1081 | * Seat objects now expose a State property. | |
1082 | ||
1083 | * We now include RPM macros for service enabling/disabling | |
1084 | based on the preset logic. We recommend RPM based | |
1085 | distributions to make use of these macros if possible. This | |
1086 | makes it simpler to reuse RPM spec files across | |
1087 | distributions. | |
1088 | ||
1089 | * We now make sure that the collected systemd unit name is | |
1090 | always valid when services log to the journal via | |
1091 | STDOUT/STDERR. | |
1092 | ||
1093 | * There's a new man page kernel-command-line(7) detailing all | |
1094 | command line options we understand. | |
1095 | ||
1096 | * The fstab generator may now be disabled at boot by passing | |
1097 | fstab=0 on the kernel command line. | |
1098 | ||
91ac7425 | 1099 | * A new kernel command line option modules-load= is now understood |
b5b4c94a LP |
1100 | to load a specific kernel module statically, early at boot. |
1101 | ||
1102 | * Unit names specified on the systemctl command line are now | |
1103 | automatically escaped as needed. Also, if file system or | |
1104 | device paths are specified they are automatically turned | |
1105 | into the appropriate mount or device unit names. Example: | |
1106 | ||
1107 | systemctl status /home | |
1108 | systemctl status /dev/sda | |
1109 | ||
1110 | * The SysVConsole= configuration option has been removed from | |
1111 | system.conf parsing. | |
1112 | ||
1113 | * The SysV search path is no longer exported on the D-Bus | |
1114 | Manager object. | |
1115 | ||
1116 | * The Names= option is been removed from unit file parsing. | |
1117 | ||
1118 | * There's a new man page bootup(7) detailing the boot process. | |
1119 | ||
1120 | * Every unit and every generator we ship with systemd now | |
1121 | comes with full documentation. The self-explanatory boot is | |
1122 | complete. | |
1123 | ||
1124 | * A couple of services gained "systemd-" prefixes in their | |
1125 | name if they wrap systemd code, rather than only external | |
1126 | code. Among them fsck@.service which is now | |
1127 | systemd-fsck@.service. | |
1128 | ||
1129 | * The HaveWatchdog property has been removed from the D-Bus | |
1130 | Manager object. | |
1131 | ||
1132 | * systemd.confirm_spawn= on the kernel command line should now | |
1133 | work sensibly. | |
1134 | ||
1135 | * There's a new man page crypttab(5) which details all options | |
1136 | we actually understand. | |
1137 | ||
1138 | * systemd-nspawn gained a new --capability= switch to pass | |
1139 | additional capabilities to the container. | |
1140 | ||
1141 | * timedated will now read known NTP implementation unit names | |
5b00c016 | 1142 | from /usr/lib/systemd/ntp-units.d/*.list, |
b5b4c94a LP |
1143 | systemd-timedated-ntp.target has been removed. |
1144 | ||
1145 | * journalctl gained a new switch "-b" that lists log data of | |
1146 | the current boot only. | |
1147 | ||
1148 | * The notify socket is in the abstract namespace again, in | |
1149 | order to support daemons which chroot() at start-up. | |
1150 | ||
1151 | * There is a new Storage= configuration option for journald | |
1152 | which allows configuration of where log data should go. This | |
1153 | also provides a way to disable journal logging entirely, so | |
1154 | that data collected is only forwarded to the console, the | |
1155 | kernel log buffer or another syslog implementation. | |
1156 | ||
c4f1b862 | 1157 | * Many bugfixes and optimizations |

1166 | * "systemctl help <unit>" now shows the man page if one is |
1167 | available. | |
1168 | ||
1169 | * Several new man pages have been added. | |
1170 | ||
b5b4c94a LP |
1171 | * MaxLevelStore=, MaxLevelSyslog=, MaxLevelKMsg=, |
1172 | MaxLevelConsole= can now be specified in | |
1173 | journald.conf. These options allow reducing the amount of | |
1174 | data stored on disk or forwarded by the log level. | |
2d197285 | 1175 | |
b5b4c94a LP |
1176 | * TimerSlackNSec= can now be specified in system.conf for |

4c8cd173 LP |
1185 | * logind is now capable of (optionally) handling power and |
1186 | sleep keys as well as the lid switch. | |
1187 | ||
1188 | * journalctl now understands the syntax "journalctl | |
1189 | /usr/bin/avahi-daemon" to get all log output of a specific | |
1190 | daemon. | |
1191 | ||
1192 | * CapabilityBoundingSet= in system.conf now also influences | |
1193 | the capability bound set of usermode helpers of the kernel. | |

ea5943d3 | 1200 | CHANGES WITH 183: |
b6a86739 | 1201 | |
187076d4 LP |
1202 | * Note that we skipped 139 releases here in order to set the |
1203 | new version to something that is greater than both udev's | |
1204 | and systemd's most recent version number. | |
1205 | ||
194bbe33 KS |
1206 | * udev: all udev sources are merged into the systemd source tree now. |
1207 | All future udev development will happen in the systemd tree. It | |
1208 | is still fully supported to use the udev daemon and tools without | |
1209 | systemd running, like in initramfs or other init systems. Building | |
1210 | udev though, will require the *build* of the systemd tree, but | |
ea5943d3 | 1211 | udev can be properly *run* without systemd. |
07cd4fc1 | 1212 | |
91cf7e5c | 1213 | * udev: /lib/udev/devices/ are not read anymore; systemd-tmpfiles |
f13b388f KS |
1214 | should be used to create dead device nodes as workarounds for broken |
1215 | subsystems. | |
64661ee7 | 1216 | |
2d13da88 KS |
1217 | * udev: RUN+="socket:..." and udev_monitor_new_from_socket() is |
1218 | no longer supported. udev_monitor_new_from_netlink() needs to be | |
1219 | used to subscribe to events. | |
1220 | ||
194bbe33 KS |
1221 | * udev: when udevd is started by systemd, processes which are left |
1222 | behind by forking them off of udev rules, are unconditionally cleaned | |
1223 | up and killed now after the event handling has finished. Services or | |
1224 | daemons must be started as systemd services. Services can be | |
ea5943d3 | 1225 | pulled-in by udev to get started, but they can no longer be directly |
194bbe33 KS |
1226 | forked by udev rules. |
1227 | ||
f13b388f KS |
1228 | * udev: the daemon binary is called systemd-udevd now and installed |
1229 | in /usr/lib/systemd/. Standalone builds or non-systemd systems need | |
1230 | to adapt to that, create symlink, or rename the binary after building | |
1231 | it. | |
1232 | ||
ea5943d3 | 1233 | * libudev no longer provides these symbols: |
c1959569 KS |
1234 | udev_monitor_from_socket() |
1235 | udev_queue_get_failed_list_entry() | |
1236 | udev_get_{dev,sys,run}_path() | |
ea5943d3 | 1237 | The versions number was bumped and symbol versioning introduced. |
c1959569 | 1238 | |
ea5943d3 | 1239 | * systemd-loginctl and systemd-journalctl have been renamed |
9ae9afce | 1240 | to loginctl and journalctl to match systemctl. |
18b754d3 KS |
1241 | |
1242 | * The config files: /etc/systemd/systemd-logind.conf and | |
1243 | /etc/systemd/systemd-journald.conf have been renamed to | |
1244 | logind.conf and journald.conf. Package updates should rename | |
1245 | the files to the new names on upgrade. | |
1246 | ||
ea5943d3 LP |
1247 | * For almost all files the license is now LGPL2.1+, changed |
1248 | from the previous GPL2.0+. Exceptions are some minor stuff | |
1249 | of udev (which will be changed to LGPL2.1 eventually, too), | |
1250 | and the MIT licensed sd-daemon.[ch] library that is suitable | |
1251 | to be used as drop-in files. | |
1252 | ||
1253 | * systemd and logind now handle system sleep states, in | |
49f43d5f | 1254 | particular suspending and hibernating. |
ea5943d3 LP |
1255 | |
1256 | * logind now implements a sleep/shutdown/idle inhibiting logic | |
1257 | suitable for a variety of uses. Soonishly Lennart will blog | |
1258 | about this in more detail. | |
1259 | ||
1260 | * var-run.mount and var-lock.mount are no longer provided | |
1261 | (which prevously bind mounted these directories to their new | |
1262 | places). Distributions which have not converted these | |
1263 | directories to symlinks should consider stealing these files | |
1264 | from git history and add them downstream. | |
1265 | ||
1266 | * We introduced the Documentation= field for units and added | |
1267 | this to all our shipped units. This is useful to make it | |
3943231c | 1268 | easier to explore the boot and the purpose of the various |
ea5943d3 LP |
1269 | units. |
1270 | ||
1271 | * All smaller setup units (such as | |
1272 | systemd-vconsole-setup.service) now detect properly if they | |
1273 | are run in a container and are skipped when | |
1274 | appropriate. This guarantees an entirely noise-free boot in | |
1275 | Linux container environments such as systemd-nspawn. | |
1276 | ||
1277 | * A framework for implementing offline system updates is now | |
1278 | integrated, for details see: | |
1279 | http://freedesktop.org/wiki/Software/systemd/SystemUpdates | |
1280 | ||
1281 | * A new service type Type=idle is available now which helps us | |
1282 | avoiding ugly interleaving of getty output and boot status | |
1283 | messages. | |
1284 | ||
439d6dfd LP |
1285 | * There's now a system-wide CapabilityBoundingSet= option to |
1286 | globally reduce the set of capabilities for the | |
ea5943d3 LP |
1287 | system. This is useful to drop CAP_SYS_MKNOD, CAP_SYS_RAWIO, |
1288 | CAP_NET_RAW, CAP_SYS_MODULE, CAP_SYS_TIME, CAP_SYS_PTRACE or | |
1289 | even CAP_NET_ADMIN system-wide for secure systems. | |
1290 | ||
1291 | * There are now system-wide DefaultLimitXXX= options to | |
1292 | globally change the defaults of the various resource limits | |
1293 | for all units started by PID 1. | |
1294 | ||
1295 | * Harald Hoyer's systemd test suite has been integrated into | |
1296 | systemd which allows easy testing of systemd builds in qemu | |
1297 | and nspawn. (This is really awesome! Ask us for details!) | |
1298 | ||
3943231c LP |
1299 | * The fstab parser is now implemented as generator, not inside |
1300 | of PID 1 anymore. | |
ea5943d3 LP |
1301 | |
1302 | * systemctl will now warn you if .mount units generated from | |
1303 | /etc/fstab are out of date due to changes in fstab that | |
1304 | haven't been read by systemd yet. | |
1305 | ||
1306 | * systemd is now suitable for usage in initrds. Dracut has | |
1307 | already been updated to make use of this. With this in place | |
1308 | initrds get a slight bit faster but primarily are much | |
1309 | easier to introspect and debug since "systemctl status" in | |
1310 | the host system can be used to introspect initrd services, | |
1311 | and the journal from the initrd is kept around too. | |
1312 | ||
1313 | * systemd-delta has been added, a tool to explore differences | |
1314 | between user/admin configuration and vendor defaults. | |
1315 | ||
1316 | * PrivateTmp= now affects both /tmp and /var/tmp. | |
1317 | ||
1318 | * Boot time status messages are now much prettier and feature | |
1319 | proper english language. Booting up systemd has never been | |
1320 | so sexy. | |
1321 | ||
1322 | * Read-ahead pack files now include the inode number of all | |
1323 | files to pre-cache. When the inode changes the pre-caching | |
1324 | is not attempted. This should be nicer to deal with updated | |
1325 | packages which might result in changes of read-ahead | |
1326 | patterns. | |
1327 | ||
1328 | * We now temporaritly lower the kernel's read_ahead_kb variable | |
1329 | when collecting read-ahead data to ensure the kernel's | |
1330 | built-in read-ahead does not add noise to our measurements | |
1331 | of necessary blocks to pre-cache. | |
1332 | ||
1333 | * There's now RequiresMountsFor= to add automatic dependencies | |
1334 | for all mounts necessary for a specific file system path. | |
1335 | ||
1336 | * MountAuto= and SwapAuto= have been removed from | |
1337 | system.conf. Mounting file systems at boot has to take place | |
1338 | in systemd now. | |
1339 | ||
1340 | * nspawn now learned a new switch --uuid= to set the machine | |
1341 | ID on the command line. | |
1342 | ||
f8c0a2cb | 1343 | * nspawn now learned the -b switch to automatically search |
ea5943d3 LP |
1344 | for an init system. |
1345 | ||
1346 | * vt102 is now the default TERM for serial TTYs, upgraded from | |
1347 | vt100. | |
1348 | ||
1349 | * systemd-logind now works on VT-less systems. | |
1350 | ||
1351 | * The build tree has been reorganized. The individual | |
3943231c | 1352 | components now have directories of their own. |
ea5943d3 LP |
1353 | |
1354 | * A new condition type ConditionPathIsReadWrite= is now available. | |
1355 | ||
1356 | * nspawn learned the new -C switch to create cgroups for the | |
1357 | container in other hierarchies. | |
1358 | ||
1359 | * We now have support for hardware watchdogs, configurable in | |
1360 | system.conf. | |
1361 | ||
1362 | * The scheduled shutdown logic now has a public API. | |
1363 | ||
1364 | * We now mount /tmp as tmpfs by default, but this can be | |
1365 | masked and /etc/fstab can override it. | |
1366 | ||
1367 | * Since udisks doesn't make use of /media anymore we are not | |
1368 | mounting a tmpfs on it anymore. | |
1369 | ||
1370 | * journalctl gained a new --local switch to only interleave | |
1371 | locally generated journal files. | |
1372 | ||
1373 | * We can now load the IMA policy at boot automatically. | |
1374 | ||
1375 | * The GTK tools have been split off into a systemd-ui. | |

b6a86739 | 1389 | |
16f1239e LP |
1390 | * This is mostly a bugfix release |
1391 | ||
1392 | * Support optional initialization of the machine ID from the | |
1393 | KVM or container configured UUID. | |
1394 | ||
1395 | * Support immediate reboots with "systemctl reboot -ff" | |
1396 | ||
1397 | * Show /etc/os-release data in systemd-analyze output | |
1398 | ||
1399 | * Many bugfixes for the journal, including endianess fixes and | |
1400 | ensuring that disk space enforcement works | |
1401 | ||
1402 | * sd-login.h is C++ comptaible again | |
1403 | ||
1404 | * Extend the /etc/os-release format on request of the Debian | |
1405 | folks | |
1406 | ||
1407 | * We now refuse non-UTF8 strings used in various configuration | |
1408 | and unit files. This is done to ensure we don't pass invalid | |
1409 | data over D-Bus or expose it elsewhere. | |
1410 | ||
1411 | * Register Mimo USB Screens as suitable for automatic seat | |
1412 | configuration | |
1413 | ||
1414 | * Read SELinux client context from journal clients in a race | |
1415 | free fashion | |
1416 | ||
1417 | * Reorder configuration file lookup order. /etc now always | |
1418 | overrides /run in order to allow the administrator to always | |
1419 | and unconditionally override vendor supplied or | |
1420 | automatically generated data. | |
1421 | ||
1422 | * The various user visible bits of the journal now have man | |
1423 | pages. We still lack man pages for the journal API calls | |
1424 | however. | |
1425 | ||
1426 | * We now ship all man pages in HTML format again in the | |
1427 | tarball. | |

b6a86739 | 1435 | |
437b7dee LP |
1436 | * This is mostly a bugfix release |
1437 | ||
1438 | * systems lacking /etc/os-release are no longer supported. | |
1439 | ||
1440 | * Various functionality updates to libsystemd-login.so | |
1441 | ||
1442 | * Track class of PAM logins to distuingish greeters from | |
1443 | normal user logins. | |

b6a86739 | 1449 | |
204fa33c LP |
1450 | * This is an important bugfix release for v41. |
1451 | ||
1452 | * Building man pages is now optional which should be useful | |
1453 | for those building systemd from git but unwilling to install | |
1454 | xsltproc. | |
1455 | ||
1456 | * Watchdog support for supervising services is now usable. In | |
1457 | a future release support for hardware watchdogs | |
1458 | (i.e. /dev/watchdog) will be added building on this. | |
1459 | ||
1460 | * Service start rate limiting is now configurable and can be | |
1461 | turned off per service. When a start rate limit is hit a | |
1462 | reboot can automatically be triggered. | |
1463 | ||
1464 | * New CanReboot(), CanPowerOff() bus calls in systemd-logind. | |

e0d25329 | 1470 | CHANGES WITH 41: |
b6a86739 | 1471 | |
e0d25329 KS |
1472 | * The systemd binary is installed /usr/lib/systemd/systemd now; |
1473 | An existing /sbin/init symlink needs to be adapted with the | |
1474 | package update. | |
1475 | ||
b13df964 LP |
1476 | * The code that loads kernel modules has been ported to invoke |
1477 | libkmod directly, instead of modprobe. This means we do not | |
1478 | support systems with module-init-tools anymore. | |
1479 | ||
1480 | * Watchdog support is now already useful, but still not | |
1481 | complete. | |
1482 | ||
1483 | * A new kernel command line option systemd.setenv= is | |
1484 | understood to set system wide environment variables | |
1485 | dynamically at boot. | |
1486 | ||
ccd07a08 LP |
1487 | * We now limit the set of capabilities of systemd-journald. |
1488 | ||
353e12c2 LP |
1489 | * We now set SIGPIPE to ignore by default, since it only is |
1490 | useful in shell pipelines, and has little use in general | |
1491 | code. This can be disabled with IgnoreSIPIPE=no in unit | |
1492 | files. | |

b6a86739 | 1499 | |
d26e4270 LP |
1500 | * This is mostly a bugfix release |
1501 | ||
1502 | * We now expose the reason why a service failed in the | |
1503 | "Result" D-Bus property. | |
1504 | ||
1505 | * Rudimentary service watchdog support (will be completed over | |
1506 | the next few releases.) | |
1507 | ||
1508 | * When systemd forks off in order execute some service we will | |
1509 | now immediately changes its argv[0] to reflect which process | |
1510 | it will execute. This is useful to minimize the time window | |
1511 | with a generic argv[0], which makes bootcharts more useful | |

220a21d3 | 1517 | CHANGES WITH 39: |
b6a86739 | 1518 | |
220a21d3 LP |
1519 | * This is mostly a test release, but incorporates many |
1520 | bugfixes. | |
1521 | ||
1522 | * New systemd-cgtop tool to show control groups by their | |
1523 | resource usage. | |
1524 | ||
1525 | * Linking against libacl for ACLs is optional again. If | |
1526 | disabled, support tracking device access for active logins | |
1527 | goes becomes unavailable, and so does access to the user | |
1528 | journals by the respective users. | |
1529 | ||
1530 | * If a group "adm" exists, journal files are automatically | |
1531 | owned by them, thus allow members of this group full access | |
1532 | to the system journal as well as all user journals. | |
1533 | ||
1534 | * The journal now stores the SELinux context of the logging | |
1535 | client for all entries. | |
1536 | ||
1537 | * Add C++ inclusion guards to all public headers | |
1538 | ||
1539 | * New output mode "cat" in the journal to print only text | |
1540 | messages, without any meta data like date or time. | |
1541 | ||
1542 | * Include tiny X server wrapper as a temporary stop-gap to | |
1543 | teach XOrg udev display enumeration. This is used by display | |
1544 | managers such as gdm, and will go away as soon as XOrg | |
1545 | learned native udev hotplugging for display devices. | |
1546 | ||
1547 | * Add new systemd-cat tool for executing arbitrary programs | |
1548 | with STDERR/STDOUT connected to the journal. Can also act as | |
1549 | BSD logger replacement, and does so by default. | |
1550 | ||
1551 | * Optionally store all locally generated coredumps in the | |
1552 | journal along with meta data. | |
1553 | ||
1554 | * systemd-tmpfiles learnt four new commands: n, L, c, b, for | |
1555 | writing short strings to files (for usage for /sys), and for | |
1556 | creating symlinks, character and block device nodes. | |
1557 | ||
1558 | * New unit file option ControlGroupPersistent= to make cgroups | |
1559 | persistent, following the mechanisms outlined in | |
1560 | http://www.freedesktop.org/wiki/Software/systemd/PaxControlGroups | |
1561 | ||
1562 | * Support multiple local RTCs in a sane way | |
1563 | ||
1564 | * No longer monopolize IO when replaying readahead data on | |
1565 | rotating disks, since we might starve non-file-system IO to | |
1566 | death, since fanotify() will not see accesses done by blkid, | |
1567 | or fsck. | |
1568 | ||
1569 | * Don't show kernel threads in systemd-cgls anymore, unless | |
1570 | requested with new -k switch. | |

1575 | CHANGES WITH 38: | |
b6a86739 | 1576 | |
220a21d3 LP |
1577 | * This is mostly a test release, but incorporates many |
1578 | bugfixes. | |
1579 | ||
1580 | * The git repository moved to: | |
1581 | git://anongit.freedesktop.org/systemd/systemd | |
1582 | ssh://git.freedesktop.org/git/systemd/systemd | |
1583 | ||
1584 | * First release with the journal | |
1585 | http://0pointer.de/blog/projects/the-journal.html | |
1586 | ||
1587 | * The journal replaces both systemd-kmsg-syslogd and | |
1588 | systemd-stdout-bridge. | |
1589 | ||
1590 | * New sd_pid_get_unit() API call in libsystemd-logind | |
1591 | ||
1592 | * Many systemadm clean-ups | |
1593 | ||
1594 | * Introduce remote-fs-pre.target which is ordered before all | |
1595 | remote mounts and may be used to start services before all | |
1596 | remote mounts. | |
1597 | ||
1598 | * Added Mageia support | |
1599 | ||
1600 | * Add bash completion for systemd-loginctl | |
1601 | ||
1602 | * Actively monitor PID file creation for daemons which exit in | |
1603 | the parent process before having finished writing the PID | |
1604 | file in the daemon process. Daemons which do this need to be | |
1605 | fixed (i.e. PID file creation must have finished before the | |
1606 | parent exits), but we now react a bit more gracefully to them. | |
1607 | ||
1608 | * Add colourful boot output, mimicking the well-known output | |
1609 | of existing distributions. | |
1610 | ||
1611 | * New option PassCredentials= for socket units, for | |
1612 | compatibility with a recent kernel ABI breakage. | |
1613 | ||
1614 | * /etc/rc.local is now hooked in via a generator binary, and | |
1615 | thus will no longer act as synchronization point during | |
1616 | boot. | |
1617 | ||
1618 | * systemctl list-unit-files now supports --root=. | |
1619 | ||
1620 | * systemd-tmpfiles now understands two new commands: z, Z for | |
1621 | relabelling files according to the SELinux database. This is | |
1622 | useful to apply SELinux labels to specific files in /sys, | |
1623 | among other things. | |
1624 | ||
1625 | * Output of SysV services is now forwarded to both the console | |
1626 | and the journal by default, not only just the console. | |
1627 | ||
1628 | * New man pages for all APIs from libsystemd-login. | |
1629 | ||
1630 | * The build tree got reorganized and a the build system is a | |
1631 | lot more modular allowing embedded setups to specifically | |
1632 | select the components of systemd they are interested in. | |
1633 | ||
1634 | * Support for Linux systems lacking the kernel VT subsystem is | |
1635 | restored. | |
1636 | ||
1637 | * configure's --with-rootdir= got renamed to | |
1638 | --with-rootprefix= to follow the naming used by udev and | |
1639 | kmod | |
1640 | ||
1641 | * Unless specified otherwise we'll now install to /usr instead | |
1642 | of /usr/local by default. | |
1643 | ||
1644 | * Processes with '@' in argv[0][0] are now excluded from the | |
1645 | final shut-down killing spree, following the logic explained | |
1646 | in: | |
1647 | http://www.freedesktop.org/wiki/Software/systemd/RootStorageDaemons | |
1648 | ||
1649 | * All processes remaining in a service cgroup when we enter | |
1650 | the START or START_PRE states are now killed with | |
1651 | SIGKILL. That means it is no longer possible to spawn | |
1652 | background processes from ExecStart= lines (which was never | |
1653 | supported anyway, and bad style). | |
1654 | ||
1655 | * New PropagateReloadTo=/PropagateReloadFrom= options to bind | |
1656 | reloading of units together. | |
1657 | ||
