I would like NUT to hibernate my PC instead of shutting it down when ONBATT event is registered. So I've put:
SHUTDOWNCMD "systemctl hibernate" to /etc/ups/upsmon.conf.
But this works only once, unless there's a hack in /usr/lib/systemd/system-sleep/ which stops nut-server.service during hibernation and starts it during wake up, there also needs to be starting of nut-monitor.service specified. Otherwise nut-monitor.service reports to be "inactive (dead)" after waking up so no ONBATT event is registered and thus no hibernation takes place. In openSUSE's NUT package, currently there's a hack /usr/lib/systemd/system-sleep/nut.sh for it and is broken so it needs to be fixed manually.
After checking "man systemd-sleep", it states that scripts in /usr/lib/systemd/system-sleep/ are considered hacks for applications not using the so called "inhibitor interface".
If NUT would use inhibitor interface, there wouldn't be a need for /usr/lib/systemd/system-sleep/ hacks implemented by individual distros and my PC could be hibernated by NUT without problem.
Tested in OS: openSUSE Leap 15.3. with NUT v.2.7.4.
