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 KS |
10 | |
11 | * udev: /lib/udev/devices/ are not read anymore; tmpfiles should | |
12 | be used to create workarounds for broken subsystems. | |
64661ee7 | 13 | |
2d13da88 KS |
14 | * udev: RUN+="socket:..." and udev_monitor_new_from_socket() is |
15 | no longer supported. udev_monitor_new_from_netlink() needs to be | |
16 | used to subscribe to events. | |
17 | ||
194bbe33 KS |
18 | * udev: when udevd is started by systemd, processes which are left |
19 | behind by forking them off of udev rules, are unconditionally cleaned | |
20 | up and killed now after the event handling has finished. Services or | |
21 | daemons must be started as systemd services. Services can be | |
22 | pulled-in by udev to ge started, but they can no longer be directly | |
23 | forked by udev rules. | |
24 | ||
18b754d3 KS |
25 | * systemd-logingctl and systemd-journalctl have been renamed |
26 | to logingctl and journalctl to match systemctl. | |
27 | ||
28 | * The config files: /etc/systemd/systemd-logind.conf and | |
29 | /etc/systemd/systemd-journald.conf have been renamed to | |
30 | logind.conf and journald.conf. Package updates should rename | |
31 | the files to the new names on upgrade. | |
32 | ||

33 | CHANGES WITH 44: |
34 | * This is mostly a bugfix release | |
35 | ||
36 | * Support optional initialization of the machine ID from the | |
37 | KVM or container configured UUID. | |
38 | ||
39 | * Support immediate reboots with "systemctl reboot -ff" | |
40 | ||
41 | * Show /etc/os-release data in systemd-analyze output | |
42 | ||
43 | * Many bugfixes for the journal, including endianess fixes and | |
44 | ensuring that disk space enforcement works | |
45 | ||
46 | * sd-login.h is C++ comptaible again | |
47 | ||
48 | * Extend the /etc/os-release format on request of the Debian | |
49 | folks | |
50 | ||
51 | * We now refuse non-UTF8 strings used in various configuration | |
52 | and unit files. This is done to ensure we don't pass invalid | |
53 | data over D-Bus or expose it elsewhere. | |
54 | ||
55 | * Register Mimo USB Screens as suitable for automatic seat | |
56 | configuration | |
57 | ||
58 | * Read SELinux client context from journal clients in a race | |
59 | free fashion | |
60 | ||
61 | * Reorder configuration file lookup order. /etc now always | |
62 | overrides /run in order to allow the administrator to always | |
63 | and unconditionally override vendor supplied or | |
64 | automatically generated data. | |
65 | ||
66 | * The various user visible bits of the journal now have man | |
67 | pages. We still lack man pages for the journal API calls | |
68 | however. | |
69 | ||
70 | * We now ship all man pages in HTML format again in the | |
71 | tarball. | |

78 | CHANGES WITH 43: |
79 | * This is mostly a bugfix release | |
80 | ||
81 | * systems lacking /etc/os-release are no longer supported. | |
82 | ||
83 | * Various functionality updates to libsystemd-login.so | |
84 | ||
85 | * Track class of PAM logins to distuingish greeters from | |
86 | normal user logins. | |

91 | CHANGES WITH 42: |
92 | * This is an important bugfix release for v41. | |
93 | ||
94 | * Building man pages is now optional which should be useful | |
95 | for those building systemd from git but unwilling to install | |
96 | xsltproc. | |
97 | ||
98 | * Watchdog support for supervising services is now usable. In | |
99 | a future release support for hardware watchdogs | |
100 | (i.e. /dev/watchdog) will be added building on this. | |
101 | ||
102 | * Service start rate limiting is now configurable and can be | |
103 | turned off per service. When a start rate limit is hit a | |
104 | reboot can automatically be triggered. | |
105 | ||
106 | * New CanReboot(), CanPowerOff() bus calls in systemd-logind. | |

112 | CHANGES WITH 41: |
113 | * The systemd binary is installed /usr/lib/systemd/systemd now; | |
114 | An existing /sbin/init symlink needs to be adapted with the | |
115 | package update. | |
116 | ||
b13df964 LP |
117 | * The code that loads kernel modules has been ported to invoke |
118 | libkmod directly, instead of modprobe. This means we do not | |
119 | support systems with module-init-tools anymore. | |
120 | ||
121 | * Watchdog support is now already useful, but still not | |
122 | complete. | |
123 | ||
124 | * A new kernel command line option systemd.setenv= is | |
125 | understood to set system wide environment variables | |
126 | dynamically at boot. | |
127 | ||
ccd07a08 LP |
128 | * We now limit the set of capabilities of systemd-journald. |
129 | ||
353e12c2 LP |
130 | * We now set SIGPIPE to ignore by default, since it only is |
131 | useful in shell pipelines, and has little use in general | |
132 | code. This can be disabled with IgnoreSIPIPE=no in unit | |
133 | files. | |

139 | CHANGES WITH 40: |
140 | * This is mostly a bugfix release | |
141 | ||
142 | * We now expose the reason why a service failed in the | |
143 | "Result" D-Bus property. | |
144 | ||
145 | * Rudimentary service watchdog support (will be completed over | |
146 | the next few releases.) | |
147 | ||
148 | * When systemd forks off in order execute some service we will | |
149 | now immediately changes its argv[0] to reflect which process | |
150 | it will execute. This is useful to minimize the time window | |
151 | with a generic argv[0], which makes bootcharts more useful | |

157 | CHANGES WITH 39: |
158 | * This is mostly a test release, but incorporates many | |
159 | bugfixes. | |
160 | ||
161 | * New systemd-cgtop tool to show control groups by their | |
162 | resource usage. | |
163 | ||
164 | * Linking against libacl for ACLs is optional again. If | |
165 | disabled, support tracking device access for active logins | |
166 | goes becomes unavailable, and so does access to the user | |
167 | journals by the respective users. | |
168 | ||
169 | * If a group "adm" exists, journal files are automatically | |
170 | owned by them, thus allow members of this group full access | |
171 | to the system journal as well as all user journals. | |
172 | ||
173 | * The journal now stores the SELinux context of the logging | |
174 | client for all entries. | |
175 | ||
176 | * Add C++ inclusion guards to all public headers | |
177 | ||
178 | * New output mode "cat" in the journal to print only text | |
179 | messages, without any meta data like date or time. | |
180 | ||
181 | * Include tiny X server wrapper as a temporary stop-gap to | |
182 | teach XOrg udev display enumeration. This is used by display | |
183 | managers such as gdm, and will go away as soon as XOrg | |
184 | learned native udev hotplugging for display devices. | |
185 | ||
186 | * Add new systemd-cat tool for executing arbitrary programs | |
187 | with STDERR/STDOUT connected to the journal. Can also act as | |
188 | BSD logger replacement, and does so by default. | |
189 | ||
190 | * Optionally store all locally generated coredumps in the | |
191 | journal along with meta data. | |
192 | ||
193 | * systemd-tmpfiles learnt four new commands: n, L, c, b, for | |
194 | writing short strings to files (for usage for /sys), and for | |
195 | creating symlinks, character and block device nodes. | |
196 | ||
197 | * New unit file option ControlGroupPersistent= to make cgroups | |
198 | persistent, following the mechanisms outlined in | |
199 | http://www.freedesktop.org/wiki/Software/systemd/PaxControlGroups | |
200 | ||
201 | * Support multiple local RTCs in a sane way | |
202 | ||
203 | * No longer monopolize IO when replaying readahead data on | |
204 | rotating disks, since we might starve non-file-system IO to | |
205 | death, since fanotify() will not see accesses done by blkid, | |
206 | or fsck. | |
207 | ||
208 | * Don't show kernel threads in systemd-cgls anymore, unless | |
209 | requested with new -k switch. | |

214 | CHANGES WITH 38: | |
215 | * This is mostly a test release, but incorporates many | |
216 | bugfixes. | |
217 | ||
218 | * The git repository moved to: | |
219 | git://anongit.freedesktop.org/systemd/systemd | |
220 | ssh://git.freedesktop.org/git/systemd/systemd | |
221 | ||
222 | * First release with the journal | |
223 | http://0pointer.de/blog/projects/the-journal.html | |
224 | ||
225 | * The journal replaces both systemd-kmsg-syslogd and | |
226 | systemd-stdout-bridge. | |
227 | ||
228 | * New sd_pid_get_unit() API call in libsystemd-logind | |
229 | ||
230 | * Many systemadm clean-ups | |
231 | ||
232 | * Introduce remote-fs-pre.target which is ordered before all | |
233 | remote mounts and may be used to start services before all | |
234 | remote mounts. | |
235 | ||
236 | * Added Mageia support | |
237 | ||
238 | * Add bash completion for systemd-loginctl | |
239 | ||
240 | * Actively monitor PID file creation for daemons which exit in | |
241 | the parent process before having finished writing the PID | |
242 | file in the daemon process. Daemons which do this need to be | |
243 | fixed (i.e. PID file creation must have finished before the | |
244 | parent exits), but we now react a bit more gracefully to them. | |
245 | ||
246 | * Add colourful boot output, mimicking the well-known output | |
247 | of existing distributions. | |
248 | ||
249 | * New option PassCredentials= for socket units, for | |
250 | compatibility with a recent kernel ABI breakage. | |
251 | ||
252 | * /etc/rc.local is now hooked in via a generator binary, and | |
253 | thus will no longer act as synchronization point during | |
254 | boot. | |
255 | ||
256 | * systemctl list-unit-files now supports --root=. | |
257 | ||
258 | * systemd-tmpfiles now understands two new commands: z, Z for | |
259 | relabelling files according to the SELinux database. This is | |
260 | useful to apply SELinux labels to specific files in /sys, | |
261 | among other things. | |
262 | ||
263 | * Output of SysV services is now forwarded to both the console | |
264 | and the journal by default, not only just the console. | |
265 | ||
266 | * New man pages for all APIs from libsystemd-login. | |
267 | ||
268 | * The build tree got reorganized and a the build system is a | |
269 | lot more modular allowing embedded setups to specifically | |
270 | select the components of systemd they are interested in. | |
271 | ||
272 | * Support for Linux systems lacking the kernel VT subsystem is | |
273 | restored. | |
274 | ||
275 | * configure's --with-rootdir= got renamed to | |
276 | --with-rootprefix= to follow the naming used by udev and | |
277 | kmod | |
278 | ||
279 | * Unless specified otherwise we'll now install to /usr instead | |
280 | of /usr/local by default. | |
281 | ||
282 | * Processes with '@' in argv[0][0] are now excluded from the | |
283 | final shut-down killing spree, following the logic explained | |
284 | in: | |
285 | http://www.freedesktop.org/wiki/Software/systemd/RootStorageDaemons | |
286 | ||
287 | * All processes remaining in a service cgroup when we enter | |
288 | the START or START_PRE states are now killed with | |
289 | SIGKILL. That means it is no longer possible to spawn | |
290 | background processes from ExecStart= lines (which was never | |
291 | supported anyway, and bad style). | |
292 | ||
293 | * New PropagateReloadTo=/PropagateReloadFrom= options to bind | |
294 | reloading of units together. | |
