relicense to LGPLv2.1 (with exceptions) We finally got the OK from all contributors with non-trivial commits to relicense systemd from GPL2+ to LGPL2.1+. Some udev bits continue to be GPL2+ for now, but we are looking into relicensing them too, to allow free copy/paste of all code within systemd. The bits that used to be MIT continue to be MIT. The big benefit of the relicensing is that closed source code may now link against libsystemd-login.so and friends. 2012-04-11 22:20:58 +00:00			`# under the terms of the GNU Lesser General Public License as published by`

Revert "units: ignore systemd-sysctl on shutdown" This reverts commit faeffa73a81ab5b59acfadeb571431fb0e42af70. There isn't really much point in dropping the Conflicts= since shutting down this service is basically free as it doesn't have anything running. Also, the patch was incomplete, because shutdown.target was still listed in Before=. 2013-03-23 02:10:41 +00:00			`Conflicts=shutdown.target`
units/systemd-sysctl.service.in: run after load-modules Modules might or will register new sysctl options. [zj: This mechanism of adding modules just to reliably set sysctl attributes is not ideal. Nevertheless, sysctl for dynamically created attributes is simply broken, and this is the easiest workaround.] https://bugzilla.redhat.com/show_bug.cgi?id=1022977 https://bugzilla.novell.com/show_bug.cgi?id=725412 2013-03-23 02:54:16 +00:00			`After=systemd-modules-load.service`

sysctl: run sysctl service if /proc/sys/net is writable (#4425) This simply changes this line: ConditionPathIsReadWrite=/proc/sys/ to this: ConditionPathIsReadWrite=/proc/sys/net/ The background for this is that the latter is namespaced through network namespacing usually and hence frequently set as writable in containers, even though the former is kept read-only. If /proc/sys is read-only but /proc/sys/net is writable we should run the sysctl service, as useful settings may be made in this case.

Drop split-usr and unmerged-usr support As previously announced, execute order 66: https://lists.freedesktop.org/archives/systemd-devel/2022-September/048352.html The meson options split-usr, rootlibdir and rootprefix become no-ops that print a warning if they are set to anything other than the default values. We can remove them in a future release. 2023-06-12 01:15:19 +00:00			`ExecStart={{LIBEXECDIR}}/systemd-sysctl`
units: specify timeouts for more oneshot services Even trivial service occasionally get stuck, for example when there's a problem with the journal. There's nothing more annoying that looking at the cylon eye for a job with an infinite timeout. Use standard 90s for jobs that do some work, and 30s for those which should be almost instantenous. 2015-04-17 01:41:18 +00:00			`TimeoutSec=90s`
