Good day, I recently joined apcupsd (APC UPS Power Control Daemon)

After a power failure, apcupsd shuts down the system with a command
almost identical to
shutdown -h -H now
Usually when you normally shutdown your system, you may notice certain
services taking too much time to terminate and triggering a timeout
value before systemd forces them to terminate. I would like to ask if
there is a way to force the system to shutdown without waiting for these
timeouts in case an emergency like a power failure.


You can force shutdown without going via normal stop of services.

systemctl --force poweroff

but that is only a part of the solution because normally most services don't take long to stop and they should be normally stopped whenever possible

the real solution would a option to reduce the timeouts

systemctl --timeout=5 poweroff
