64661ee7 | 3 | CHANGES WITH 182: |
194bbe33 KS |
4 | * udev: all udev sources are merged into the systemd source tree now. |
5 | All future udev development will happen in the systemd tree. It | |
6 | is still fully supported to use the udev daemon and tools without | |
7 | systemd running, like in initramfs or other init systems. Building | |
8 | udev though, will require the *build* of the systemd tree, but | |
9 | udev can be properly *run* without systems. | |
07cd4fc1 | 10 | |
91cf7e5c | 11 | * udev: /lib/udev/devices/ are not read anymore; systemd-tmpfiles |
f13b388f KS |
12 | should be used to create dead device nodes as workarounds for broken |
13 | subsystems. | |
64661ee7 | 14 | |
2d13da88 KS |
15 | * udev: RUN+="socket:..." and udev_monitor_new_from_socket() is |
16 | no longer supported. udev_monitor_new_from_netlink() needs to be | |
17 | used to subscribe to events. | |
18 | ||
194bbe33 KS |
19 | * udev: when udevd is started by systemd, processes which are left |
20 | behind by forking them off of udev rules, are unconditionally cleaned | |
21 | up and killed now after the event handling has finished. Services or | |
22 | daemons must be started as systemd services. Services can be | |
23 | pulled-in by udev to ge started, but they can no longer be directly | |
24 | forked by udev rules. | |
25 | ||
f13b388f KS |
26 | * udev: the daemon binary is called systemd-udevd now and installed |
27 | in /usr/lib/systemd/. Standalone builds or non-systemd systems need | |
28 | to adapt to that, create symlink, or rename the binary after building | |
29 | it. | |
30 | ||
18b754d3 KS |
31 | * systemd-logingctl and systemd-journalctl have been renamed |
32 | to logingctl and journalctl to match systemctl. | |
33 | ||
34 | * The config files: /etc/systemd/systemd-logind.conf and | |
35 | /etc/systemd/systemd-journald.conf have been renamed to | |
36 | logind.conf and journald.conf. Package updates should rename | |
37 | the files to the new names on upgrade. | |
38 | ||

39 | CHANGES WITH 44: |
40 | * This is mostly a bugfix release | |
41 | ||
42 | * Support optional initialization of the machine ID from the | |
43 | KVM or container configured UUID. | |
44 | ||
45 | * Support immediate reboots with "systemctl reboot -ff" | |
46 | ||
47 | * Show /etc/os-release data in systemd-analyze output | |
48 | ||
49 | * Many bugfixes for the journal, including endianess fixes and | |
50 | ensuring that disk space enforcement works | |
51 | ||
52 | * sd-login.h is C++ comptaible again | |
53 | ||
54 | * Extend the /etc/os-release format on request of the Debian | |
55 | folks | |
56 | ||
57 | * We now refuse non-UTF8 strings used in various configuration | |
58 | and unit files. This is done to ensure we don't pass invalid | |
59 | data over D-Bus or expose it elsewhere. | |
60 | ||
61 | * Register Mimo USB Screens as suitable for automatic seat | |
62 | configuration | |
63 | ||
64 | * Read SELinux client context from journal clients in a race | |
65 | free fashion | |
66 | ||
67 | * Reorder configuration file lookup order. /etc now always | |
68 | overrides /run in order to allow the administrator to always | |
69 | and unconditionally override vendor supplied or | |
70 | automatically generated data. | |
71 | ||
72 | * The various user visible bits of the journal now have man | |
73 | pages. We still lack man pages for the journal API calls | |
74 | however. | |
75 | ||
76 | * We now ship all man pages in HTML format again in the | |
77 | tarball. | |

84 | CHANGES WITH 43: |
85 | * This is mostly a bugfix release | |
86 | ||
87 | * systems lacking /etc/os-release are no longer supported. | |
88 | ||
89 | * Various functionality updates to libsystemd-login.so | |
90 | ||
91 | * Track class of PAM logins to distuingish greeters from | |
92 | normal user logins. | |

97 | CHANGES WITH 42: |
98 | * This is an important bugfix release for v41. | |
99 | ||
100 | * Building man pages is now optional which should be useful | |
101 | for those building systemd from git but unwilling to install | |
102 | xsltproc. | |
103 | ||
104 | * Watchdog support for supervising services is now usable. In | |
105 | a future release support for hardware watchdogs | |
106 | (i.e. /dev/watchdog) will be added building on this. | |
107 | ||
108 | * Service start rate limiting is now configurable and can be | |
109 | turned off per service. When a start rate limit is hit a | |
110 | reboot can automatically be triggered. | |
111 | ||
112 | * New CanReboot(), CanPowerOff() bus calls in systemd-logind. | |

e0d25329 KS |
118 | CHANGES WITH 41: |
119 | * The systemd binary is installed /usr/lib/systemd/systemd now; | |
120 | An existing /sbin/init symlink needs to be adapted with the | |
121 | package update. | |
122 | ||
b13df964 LP |
123 | * The code that loads kernel modules has been ported to invoke |
124 | libkmod directly, instead of modprobe. This means we do not | |
125 | support systems with module-init-tools anymore. | |
126 | ||
127 | * Watchdog support is now already useful, but still not | |
128 | complete. | |
129 | ||
130 | * A new kernel command line option systemd.setenv= is | |
131 | understood to set system wide environment variables | |
132 | dynamically at boot. | |
133 | ||
ccd07a08 LP |
134 | * We now limit the set of capabilities of systemd-journald. |
135 | ||
353e12c2 LP |
136 | * We now set SIGPIPE to ignore by default, since it only is |
137 | useful in shell pipelines, and has little use in general | |
138 | code. This can be disabled with IgnoreSIPIPE=no in unit | |
139 | files. | |

145 | CHANGES WITH 40: |
146 | * This is mostly a bugfix release | |
147 | ||
148 | * We now expose the reason why a service failed in the | |
149 | "Result" D-Bus property. | |
150 | ||
151 | * Rudimentary service watchdog support (will be completed over | |
152 | the next few releases.) | |
153 | ||
154 | * When systemd forks off in order execute some service we will | |
155 | now immediately changes its argv[0] to reflect which process | |
156 | it will execute. This is useful to minimize the time window | |
157 | with a generic argv[0], which makes bootcharts more useful | |

163 | CHANGES WITH 39: |
164 | * This is mostly a test release, but incorporates many | |
165 | bugfixes. | |
166 | ||
167 | * New systemd-cgtop tool to show control groups by their | |
168 | resource usage. | |
169 | ||
170 | * Linking against libacl for ACLs is optional again. If | |
171 | disabled, support tracking device access for active logins | |
172 | goes becomes unavailable, and so does access to the user | |
173 | journals by the respective users. | |
174 | ||
175 | * If a group "adm" exists, journal files are automatically | |
176 | owned by them, thus allow members of this group full access | |
177 | to the system journal as well as all user journals. | |
178 | ||
179 | * The journal now stores the SELinux context of the logging | |
180 | client for all entries. | |
181 | ||
182 | * Add C++ inclusion guards to all public headers | |
183 | ||
184 | * New output mode "cat" in the journal to print only text | |
185 | messages, without any meta data like date or time. | |
186 | ||
187 | * Include tiny X server wrapper as a temporary stop-gap to | |
188 | teach XOrg udev display enumeration. This is used by display | |
189 | managers such as gdm, and will go away as soon as XOrg | |
190 | learned native udev hotplugging for display devices. | |
191 | ||
192 | * Add new systemd-cat tool for executing arbitrary programs | |
193 | with STDERR/STDOUT connected to the journal. Can also act as | |
194 | BSD logger replacement, and does so by default. | |
195 | ||
196 | * Optionally store all locally generated coredumps in the | |
197 | journal along with meta data. | |
198 | ||
199 | * systemd-tmpfiles learnt four new commands: n, L, c, b, for | |
200 | writing short strings to files (for usage for /sys), and for | |
201 | creating symlinks, character and block device nodes. | |
202 | ||
203 | * New unit file option ControlGroupPersistent= to make cgroups | |
204 | persistent, following the mechanisms outlined in | |
205 | http://www.freedesktop.org/wiki/Software/systemd/PaxControlGroups | |
206 | ||
207 | * Support multiple local RTCs in a sane way | |
208 | ||
209 | * No longer monopolize IO when replaying readahead data on | |
210 | rotating disks, since we might starve non-file-system IO to | |
211 | death, since fanotify() will not see accesses done by blkid, | |
212 | or fsck. | |
213 | ||
214 | * Don't show kernel threads in systemd-cgls anymore, unless | |
215 | requested with new -k switch. | |

220 | CHANGES WITH 38: | |
221 | * This is mostly a test release, but incorporates many | |
222 | bugfixes. | |
223 | ||
224 | * The git repository moved to: | |
225 | git://anongit.freedesktop.org/systemd/systemd | |
226 | ssh://git.freedesktop.org/git/systemd/systemd | |
227 | ||
228 | * First release with the journal | |
229 | http://0pointer.de/blog/projects/the-journal.html | |
230 | ||
231 | * The journal replaces both systemd-kmsg-syslogd and | |
232 | systemd-stdout-bridge. | |
233 | ||
234 | * New sd_pid_get_unit() API call in libsystemd-logind | |
235 | ||
236 | * Many systemadm clean-ups | |
237 | ||
238 | * Introduce remote-fs-pre.target which is ordered before all | |
239 | remote mounts and may be used to start services before all | |
240 | remote mounts. | |
241 | ||
242 | * Added Mageia support | |
243 | ||
244 | * Add bash completion for systemd-loginctl | |
245 | ||
246 | * Actively monitor PID file creation for daemons which exit in | |
247 | the parent process before having finished writing the PID | |
248 | file in the daemon process. Daemons which do this need to be | |
249 | fixed (i.e. PID file creation must have finished before the | |
250 | parent exits), but we now react a bit more gracefully to them. | |
251 | ||
252 | * Add colourful boot output, mimicking the well-known output | |
253 | of existing distributions. | |
254 | ||
255 | * New option PassCredentials= for socket units, for | |
256 | compatibility with a recent kernel ABI breakage. | |
257 | ||
258 | * /etc/rc.local is now hooked in via a generator binary, and | |
259 | thus will no longer act as synchronization point during | |
260 | boot. | |
261 | ||
262 | * systemctl list-unit-files now supports --root=. | |
263 | ||
264 | * systemd-tmpfiles now understands two new commands: z, Z for | |
265 | relabelling files according to the SELinux database. This is | |
266 | useful to apply SELinux labels to specific files in /sys, | |
267 | among other things. | |
268 | ||
269 | * Output of SysV services is now forwarded to both the console | |
270 | and the journal by default, not only just the console. | |
271 | ||
272 | * New man pages for all APIs from libsystemd-login. | |
273 | ||
274 | * The build tree got reorganized and a the build system is a | |
275 | lot more modular allowing embedded setups to specifically | |
276 | select the components of systemd they are interested in. | |
277 | ||
278 | * Support for Linux systems lacking the kernel VT subsystem is | |
279 | restored. | |
280 | ||
281 | * configure's --with-rootdir= got renamed to | |
282 | --with-rootprefix= to follow the naming used by udev and | |
283 | kmod | |
284 | ||
285 | * Unless specified otherwise we'll now install to /usr instead | |
286 | of /usr/local by default. | |
287 | ||
288 | * Processes with '@' in argv[0][0] are now excluded from the | |
289 | final shut-down killing spree, following the logic explained | |
290 | in: | |
291 | http://www.freedesktop.org/wiki/Software/systemd/RootStorageDaemons | |
292 | ||
293 | * All processes remaining in a service cgroup when we enter | |
294 | the START or START_PRE states are now killed with | |
295 | SIGKILL. That means it is no longer possible to spawn | |
296 | background processes from ExecStart= lines (which was never | |
297 | supported anyway, and bad style). | |
298 | ||
299 | * New PropagateReloadTo=/PropagateReloadFrom= options to bind | |
300 | reloading of units together. | |
