ea5943d3 | 3 | CHANGES WITH 183: |
187076d4 LP |
4 | * Note that we skipped 139 releases here in order to set the |
5 | new version to something that is greater than both udev's | |
6 | and systemd's most recent version number. | |
7 | ||
194bbe33 KS |
8 | * udev: all udev sources are merged into the systemd source tree now. |
9 | All future udev development will happen in the systemd tree. It | |
10 | is still fully supported to use the udev daemon and tools without | |
11 | systemd running, like in initramfs or other init systems. Building | |
12 | udev though, will require the *build* of the systemd tree, but | |
ea5943d3 | 13 | udev can be properly *run* without systemd. |
07cd4fc1 | 14 | |
91cf7e5c | 15 | * udev: /lib/udev/devices/ are not read anymore; systemd-tmpfiles |
f13b388f KS |
16 | should be used to create dead device nodes as workarounds for broken |
17 | subsystems. | |
64661ee7 | 18 | |
2d13da88 KS |
19 | * udev: RUN+="socket:..." and udev_monitor_new_from_socket() is |
20 | no longer supported. udev_monitor_new_from_netlink() needs to be | |
21 | used to subscribe to events. | |
22 | ||
194bbe33 KS |
23 | * udev: when udevd is started by systemd, processes which are left |
24 | behind by forking them off of udev rules, are unconditionally cleaned | |
25 | up and killed now after the event handling has finished. Services or | |
26 | daemons must be started as systemd services. Services can be | |
ea5943d3 | 27 | pulled-in by udev to get started, but they can no longer be directly |
194bbe33 KS |
28 | forked by udev rules. |
29 | ||
f13b388f KS |
30 | * udev: the daemon binary is called systemd-udevd now and installed |
31 | in /usr/lib/systemd/. Standalone builds or non-systemd systems need | |
32 | to adapt to that, create symlink, or rename the binary after building | |
33 | it. | |
34 | ||
ea5943d3 | 35 | * libudev no longer provides these symbols: |
c1959569 KS |
36 | udev_monitor_from_socket() |
37 | udev_queue_get_failed_list_entry() | |
38 | udev_get_{dev,sys,run}_path() | |
ea5943d3 | 39 | The versions number was bumped and symbol versioning introduced. |
c1959569 | 40 | |
ea5943d3 | 41 | * systemd-loginctl and systemd-journalctl have been renamed |
18b754d3 KS |
42 | to logingctl and journalctl to match systemctl. |
43 | ||
44 | * The config files: /etc/systemd/systemd-logind.conf and | |
45 | /etc/systemd/systemd-journald.conf have been renamed to | |
46 | logind.conf and journald.conf. Package updates should rename | |
47 | the files to the new names on upgrade. | |
48 | ||
ea5943d3 LP |
49 | * For almost all files the license is now LGPL2.1+, changed |
50 | from the previous GPL2.0+. Exceptions are some minor stuff | |
51 | of udev (which will be changed to LGPL2.1 eventually, too), | |
52 | and the MIT licensed sd-daemon.[ch] library that is suitable | |
53 | to be used as drop-in files. | |
54 | ||
55 | * systemd and logind now handle system sleep states, in | |
56 | particulary suspending and hibernating. | |
57 | ||
58 | * logind now implements a sleep/shutdown/idle inhibiting logic | |
59 | suitable for a variety of uses. Soonishly Lennart will blog | |
60 | about this in more detail. | |
61 | ||
62 | * var-run.mount and var-lock.mount are no longer provided | |
63 | (which prevously bind mounted these directories to their new | |
64 | places). Distributions which have not converted these | |
65 | directories to symlinks should consider stealing these files | |
66 | from git history and add them downstream. | |
67 | ||
68 | * We introduced the Documentation= field for units and added | |
69 | this to all our shipped units. This is useful to make it | |
70 | easier to explore that boot and the purpose of the various | |
71 | units. | |
72 | ||
73 | * All smaller setup units (such as | |
74 | systemd-vconsole-setup.service) now detect properly if they | |
75 | are run in a container and are skipped when | |
76 | appropriate. This guarantees an entirely noise-free boot in | |
77 | Linux container environments such as systemd-nspawn. | |
78 | ||
79 | * A framework for implementing offline system updates is now | |
80 | integrated, for details see: | |
81 | http://freedesktop.org/wiki/Software/systemd/SystemUpdates | |
82 | ||
83 | * A new service type Type=idle is available now which helps us | |
84 | avoiding ugly interleaving of getty output and boot status | |
85 | messages. | |
86 | ||
87 | * There's now a system-wide CapabalityBoundingSet= option to | |
88 | globally reduce the set of capabailities for the | |
89 | system. This is useful to drop CAP_SYS_MKNOD, CAP_SYS_RAWIO, | |
90 | CAP_NET_RAW, CAP_SYS_MODULE, CAP_SYS_TIME, CAP_SYS_PTRACE or | |
91 | even CAP_NET_ADMIN system-wide for secure systems. | |
92 | ||
93 | * There are now system-wide DefaultLimitXXX= options to | |
94 | globally change the defaults of the various resource limits | |
95 | for all units started by PID 1. | |
96 | ||
97 | * Harald Hoyer's systemd test suite has been integrated into | |
98 | systemd which allows easy testing of systemd builds in qemu | |
99 | and nspawn. (This is really awesome! Ask us for details!) | |
100 | ||
101 | * The fstab parser is now implemented as generator not inside | |
102 | of PID 1. | |
103 | ||
104 | * systemctl will now warn you if .mount units generated from | |
105 | /etc/fstab are out of date due to changes in fstab that | |
106 | haven't been read by systemd yet. | |
107 | ||
108 | * systemd is now suitable for usage in initrds. Dracut has | |
109 | already been updated to make use of this. With this in place | |
110 | initrds get a slight bit faster but primarily are much | |
111 | easier to introspect and debug since "systemctl status" in | |
112 | the host system can be used to introspect initrd services, | |
113 | and the journal from the initrd is kept around too. | |
114 | ||
115 | * systemd-delta has been added, a tool to explore differences | |
116 | between user/admin configuration and vendor defaults. | |
117 | ||
118 | * PrivateTmp= now affects both /tmp and /var/tmp. | |
119 | ||
120 | * Boot time status messages are now much prettier and feature | |
121 | proper english language. Booting up systemd has never been | |
122 | so sexy. | |
123 | ||
124 | * Read-ahead pack files now include the inode number of all | |
125 | files to pre-cache. When the inode changes the pre-caching | |
126 | is not attempted. This should be nicer to deal with updated | |
127 | packages which might result in changes of read-ahead | |
128 | patterns. | |
129 | ||
130 | * We now temporaritly lower the kernel's read_ahead_kb variable | |
131 | when collecting read-ahead data to ensure the kernel's | |
132 | built-in read-ahead does not add noise to our measurements | |
133 | of necessary blocks to pre-cache. | |
134 | ||
135 | * There's now RequiresMountsFor= to add automatic dependencies | |
136 | for all mounts necessary for a specific file system path. | |
137 | ||
138 | * MountAuto= and SwapAuto= have been removed from | |
139 | system.conf. Mounting file systems at boot has to take place | |
140 | in systemd now. | |
141 | ||
142 | * nspawn now learned a new switch --uuid= to set the machine | |
143 | ID on the command line. | |
144 | ||
145 | * nspawn now loearned the -b switch to automatically search | |
146 | for an init system. | |
147 | ||
148 | * vt102 is now the default TERM for serial TTYs, upgraded from | |
149 | vt100. | |
150 | ||
151 | * systemd-logind now works on VT-less systems. | |
152 | ||
153 | * The build tree has been reorganized. The individual | |
154 | componets now have directories of their own. | |
155 | ||
156 | * A new condition type ConditionPathIsReadWrite= is now available. | |
157 | ||
158 | * nspawn learned the new -C switch to create cgroups for the | |
159 | container in other hierarchies. | |
160 | ||
161 | * We now have support for hardware watchdogs, configurable in | |
162 | system.conf. | |
163 | ||
164 | * The scheduled shutdown logic now has a public API. | |
165 | ||
166 | * We now mount /tmp as tmpfs by default, but this can be | |
167 | masked and /etc/fstab can override it. | |
168 | ||
169 | * Since udisks doesn't make use of /media anymore we are not | |
170 | mounting a tmpfs on it anymore. | |
171 | ||
172 | * journalctl gained a new --local switch to only interleave | |
173 | locally generated journal files. | |
174 | ||
175 | * We can now load the IMA policy at boot automatically. | |
176 | ||
177 | * The GTK tools have been split off into a systemd-ui. | |
178 | ||
16f1239e LP |
179 | CHANGES WITH 44: |
180 | * This is mostly a bugfix release | |
181 | ||
182 | * Support optional initialization of the machine ID from the | |
183 | KVM or container configured UUID. | |
184 | ||
185 | * Support immediate reboots with "systemctl reboot -ff" | |
186 | ||
187 | * Show /etc/os-release data in systemd-analyze output | |
188 | ||
189 | * Many bugfixes for the journal, including endianess fixes and | |
190 | ensuring that disk space enforcement works | |
191 | ||
192 | * sd-login.h is C++ comptaible again | |
193 | ||
194 | * Extend the /etc/os-release format on request of the Debian | |
195 | folks | |
196 | ||
197 | * We now refuse non-UTF8 strings used in various configuration | |
198 | and unit files. This is done to ensure we don't pass invalid | |
199 | data over D-Bus or expose it elsewhere. | |
200 | ||
201 | * Register Mimo USB Screens as suitable for automatic seat | |
202 | configuration | |
203 | ||
204 | * Read SELinux client context from journal clients in a race | |
205 | free fashion | |
206 | ||
207 | * Reorder configuration file lookup order. /etc now always | |
208 | overrides /run in order to allow the administrator to always | |
209 | and unconditionally override vendor supplied or | |
210 | automatically generated data. | |
211 | ||
212 | * The various user visible bits of the journal now have man | |
213 | pages. We still lack man pages for the journal API calls | |
214 | however. | |
215 | ||
216 | * We now ship all man pages in HTML format again in the | |
217 | tarball. | |

224 | CHANGES WITH 43: |
225 | * This is mostly a bugfix release | |
226 | ||
227 | * systems lacking /etc/os-release are no longer supported. | |
228 | ||
229 | * Various functionality updates to libsystemd-login.so | |
230 | ||
231 | * Track class of PAM logins to distuingish greeters from | |
232 | normal user logins. | |

237 | CHANGES WITH 42: |
238 | * This is an important bugfix release for v41. | |
239 | ||
240 | * Building man pages is now optional which should be useful | |
241 | for those building systemd from git but unwilling to install | |
242 | xsltproc. | |
243 | ||
244 | * Watchdog support for supervising services is now usable. In | |
245 | a future release support for hardware watchdogs | |
246 | (i.e. /dev/watchdog) will be added building on this. | |
247 | ||
248 | * Service start rate limiting is now configurable and can be | |
249 | turned off per service. When a start rate limit is hit a | |
250 | reboot can automatically be triggered. | |
251 | ||
252 | * New CanReboot(), CanPowerOff() bus calls in systemd-logind. | |

e0d25329 KS |
258 | CHANGES WITH 41: |
259 | * The systemd binary is installed /usr/lib/systemd/systemd now; | |
260 | An existing /sbin/init symlink needs to be adapted with the | |
261 | package update. | |
262 | ||
b13df964 LP |
263 | * The code that loads kernel modules has been ported to invoke |
264 | libkmod directly, instead of modprobe. This means we do not | |
265 | support systems with module-init-tools anymore. | |
266 | ||
267 | * Watchdog support is now already useful, but still not | |
268 | complete. | |
269 | ||
270 | * A new kernel command line option systemd.setenv= is | |
271 | understood to set system wide environment variables | |
272 | dynamically at boot. | |
273 | ||
ccd07a08 LP |
274 | * We now limit the set of capabilities of systemd-journald. |
275 | ||
353e12c2 LP |
276 | * We now set SIGPIPE to ignore by default, since it only is |
277 | useful in shell pipelines, and has little use in general | |
278 | code. This can be disabled with IgnoreSIPIPE=no in unit | |
279 | files. | |

d26e4270 LP |
285 | CHANGES WITH 40: |
286 | * This is mostly a bugfix release | |
287 | ||
288 | * We now expose the reason why a service failed in the | |
289 | "Result" D-Bus property. | |
290 | ||
291 | * Rudimentary service watchdog support (will be completed over | |
292 | the next few releases.) | |
293 | ||
294 | * When systemd forks off in order execute some service we will | |
295 | now immediately changes its argv[0] to reflect which process | |
296 | it will execute. This is useful to minimize the time window | |
297 | with a generic argv[0], which makes bootcharts more useful | |

220a21d3 LP |
303 | CHANGES WITH 39: |
304 | * This is mostly a test release, but incorporates many | |
305 | bugfixes. | |
306 | ||
307 | * New systemd-cgtop tool to show control groups by their | |
308 | resource usage. | |
309 | ||
310 | * Linking against libacl for ACLs is optional again. If | |
311 | disabled, support tracking device access for active logins | |
312 | goes becomes unavailable, and so does access to the user | |
313 | journals by the respective users. | |
314 | ||
315 | * If a group "adm" exists, journal files are automatically | |
316 | owned by them, thus allow members of this group full access | |
317 | to the system journal as well as all user journals. | |
318 | ||
319 | * The journal now stores the SELinux context of the logging | |
320 | client for all entries. | |
321 | ||
322 | * Add C++ inclusion guards to all public headers | |
323 | ||
324 | * New output mode "cat" in the journal to print only text | |
325 | messages, without any meta data like date or time. | |
326 | ||
327 | * Include tiny X server wrapper as a temporary stop-gap to | |
328 | teach XOrg udev display enumeration. This is used by display | |
329 | managers such as gdm, and will go away as soon as XOrg | |
330 | learned native udev hotplugging for display devices. | |
331 | ||
332 | * Add new systemd-cat tool for executing arbitrary programs | |
333 | with STDERR/STDOUT connected to the journal. Can also act as | |
334 | BSD logger replacement, and does so by default. | |
335 | ||
336 | * Optionally store all locally generated coredumps in the | |
337 | journal along with meta data. | |
338 | ||
339 | * systemd-tmpfiles learnt four new commands: n, L, c, b, for | |
340 | writing short strings to files (for usage for /sys), and for | |
341 | creating symlinks, character and block device nodes. | |
342 | ||
343 | * New unit file option ControlGroupPersistent= to make cgroups | |
344 | persistent, following the mechanisms outlined in | |
345 | http://www.freedesktop.org/wiki/Software/systemd/PaxControlGroups | |
346 | ||
347 | * Support multiple local RTCs in a sane way | |
348 | ||
349 | * No longer monopolize IO when replaying readahead data on | |
350 | rotating disks, since we might starve non-file-system IO to | |
351 | death, since fanotify() will not see accesses done by blkid, | |
352 | or fsck. | |
353 | ||
354 | * Don't show kernel threads in systemd-cgls anymore, unless | |
355 | requested with new -k switch. | |
356 | ||

359 | ||
360 | CHANGES WITH 38: | |
361 | * This is mostly a test release, but incorporates many | |
362 | bugfixes. | |
363 | ||
364 | * The git repository moved to: | |
365 | git://anongit.freedesktop.org/systemd/systemd | |
366 | ssh://git.freedesktop.org/git/systemd/systemd | |
367 | ||
368 | * First release with the journal | |
369 | http://0pointer.de/blog/projects/the-journal.html | |
370 | ||
371 | * The journal replaces both systemd-kmsg-syslogd and | |
372 | systemd-stdout-bridge. | |
373 | ||
374 | * New sd_pid_get_unit() API call in libsystemd-logind | |
375 | ||
376 | * Many systemadm clean-ups | |
377 | ||
378 | * Introduce remote-fs-pre.target which is ordered before all | |
379 | remote mounts and may be used to start services before all | |
380 | remote mounts. | |
381 | ||
382 | * Added Mageia support | |
383 | ||
384 | * Add bash completion for systemd-loginctl | |
385 | ||
386 | * Actively monitor PID file creation for daemons which exit in | |
387 | the parent process before having finished writing the PID | |
388 | file in the daemon process. Daemons which do this need to be | |
389 | fixed (i.e. PID file creation must have finished before the | |
390 | parent exits), but we now react a bit more gracefully to them. | |
391 | ||
392 | * Add colourful boot output, mimicking the well-known output | |
393 | of existing distributions. | |
394 | ||
395 | * New option PassCredentials= for socket units, for | |
396 | compatibility with a recent kernel ABI breakage. | |
397 | ||
398 | * /etc/rc.local is now hooked in via a generator binary, and | |
399 | thus will no longer act as synchronization point during | |
400 | boot. | |
401 | ||
402 | * systemctl list-unit-files now supports --root=. | |
403 | ||
404 | * systemd-tmpfiles now understands two new commands: z, Z for | |
405 | relabelling files according to the SELinux database. This is | |
406 | useful to apply SELinux labels to specific files in /sys, | |
407 | among other things. | |
408 | ||
409 | * Output of SysV services is now forwarded to both the console | |
410 | and the journal by default, not only just the console. | |
411 | ||
412 | * New man pages for all APIs from libsystemd-login. | |
413 | ||
414 | * The build tree got reorganized and a the build system is a | |
415 | lot more modular allowing embedded setups to specifically | |
416 | select the components of systemd they are interested in. | |
417 | ||
418 | * Support for Linux systems lacking the kernel VT subsystem is | |
419 | restored. | |
420 | ||
421 | * configure's --with-rootdir= got renamed to | |
422 | --with-rootprefix= to follow the naming used by udev and | |
423 | kmod | |
424 | ||
425 | * Unless specified otherwise we'll now install to /usr instead | |
426 | of /usr/local by default. | |
427 | ||
428 | * Processes with '@' in argv[0][0] are now excluded from the | |
429 | final shut-down killing spree, following the logic explained | |
430 | in: | |
431 | http://www.freedesktop.org/wiki/Software/systemd/RootStorageDaemons | |
432 | ||
433 | * All processes remaining in a service cgroup when we enter | |
434 | the START or START_PRE states are now killed with | |
435 | SIGKILL. That means it is no longer possible to spawn | |
436 | background processes from ExecStart= lines (which was never | |
437 | supported anyway, and bad style). | |
438 | ||
439 | * New PropagateReloadTo=/PropagateReloadFrom= options to bind | |
440 | reloading of units together. | |
