[Nut-upsuser] [EXTERNAL] Re: Tripp-Lite USB "REMOTE SHUTDOWN"

[Jim Klimov]

Wondering further: Could it be the UPS itself?

Say, something among the test commands tells it to power off after a
timeout or when load drops, and UPS announces back the FSD for its load to
hurry up powering off, so a newly started NUT forwards that to upsmon...

Might test that by booting the system without data-connection to the UPS,
to check if it is NUT and files on the system "misbehaving" or the UPS...

There are many devices of varied smartness out there, so many things are
possible.
