[Nut-upsuser] Best practice to shutdown hosts which has not NUT via upssched

[Dmitri Stepanov]

 Thank you for idea Kris. I guess I know now why my scripts doesn't work from upssched... That's because it's running as another user (_ups in my NUT-master OpenBSD box). And I tested it by hand as root. Unfortunately now I haven't ability to connect to and check my theory by practice on the system.
