more than a upsd trace, we need usbhid-ups (-DDDDD) to be able to see
what's going on...
Ie, is the device actually reporting RB
(UPS.PowerSummary.PresentStatus.NeedReplacement == 1...) or not.

the above use case should not be a problem, since an initiated shutdown
(master + slave) will go to the completion.
a variation, where the above result is desired, is load shedding, where you
want to shutdown non critical loads, to get more runtime for the critical
ones...

it indeed helps, thanks Tim.
