Buy a cheap UPS with a USB or serial connection to your
computer. Even if it only supplies power for 2 minutes, that's
enough time for the computer to receive the power outage signal
and do an orderly shutdown.
Two minutes barely covers the timeouts that can often occur when
shutting down systemd; the commonest timeout period here seems
to be 90 seconds. I wouldn't mind reducing them if that's possible.
Processes got just a few seconds with sysvinit before they were
killed.


Still it is sufficient to do an orderly shutdown when power is lost and your network hardware might be off.
The bigger issue is why would anyone use experimental drivers and the latest kernel when they are worried about reliability?
