Make org.freedesktop.systemd1.Manager.ShutdownWatchdogUSec work
org.freedesktop.systemd1.Manager has a property ShutdownWatchdogUSec. I can
change it using the following command:
busctl --system set-property org.freedesktop.systemd1 /org/freedesktop/systemd1
org.freedesktop.systemd1.Manager ShutdownWatchdogUSec t 0
But it seems that this change has no effect, and systemd still uses old value
which is read from /etc/systemd/system.conf at startup.
I looked at sources:
<a href="http://cgit.freedesktop.org/systemd/systemd/tree/src/core/main.c?id=1325ec4280dd3f00f4879c5feadd524f7ba52f7e#n2014">http://cgit.freedesktop.org/systemd/systemd/tree/src/core/main.c?id=1325ec4280dd3f00f4879c5feadd524f7ba52f7e#n2014</a>
I see that systemd uses arg_shutdown_watchdog value (the one assigned from
config file) instead of m->shutdown_watchdog (the one that user could change by
D-Bus calls). Really, we can't use m->shutdown_watchdog at that point, because
m is freed on line 1827, but we could assign arg_shutdown_watchdog =
m->shutdown_watchdog right before manager_free(m).
I suggest attached patch to fix this issue.</pre>
