[Nut-upsuser] Installing and running NUT on OpenBSD

[Jim Klimov]

Hello, sorry and puzzled to hear about that.

My guess would be permissions - while nut-scanner remains `root` (if
started as one) and sees everything, drivers default to dropping privileges
and may not see the devfs nodes (not sure OTOH which paths are involved on
OpenBSD). One experimental workaround can be adding `user=root` to
`ups.conf` entry for the device. But properly - tame whichever subsystem is
responsible for that (devd?) to let the packaged run-time user see the
device node.

Also to cobfirm tge hypothesis, you can run the driver start attempt with
higher debug verbosity, e.g.

:; upsdrvctl -DDDDDD -d start
