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.
Fixes: #4370
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.
We install two sysctl snippets ourselves, hence the condition will
always trigger, so no point in tryng to optimize things with this, it
just will make things slower, if anything.
This reverts commit faeffa73a8.
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=.
This should help making the boot process a bit easier to explore and
understand for the administrator. The simple idea is that "systemctl
status" now shows a link to documentation alongside the other status and
decriptionary information of a service.
This patch adds the necessary fields to all our shipped units if we have
proper documentation for them.
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.
