Right, this would be ideal.
I don't think I explained this correctly the last time, but there is a
potential race condition with some UPSes if the power returns after
the delayed shutdown command is sent. At that point, the machine is
committed to shutting down, so the UPS needs to turn off the outlets
as commanded. But since the power has returned, the UPS can power the
outlets back on after a few seconds.
Note1, since nut removes itself from the hid device, I presume that
this
involves removal of any corresponding /dev entries (in any case
I see none on my system, there are two entries for the UPS:
/dev/usbdev2.2_ep00 and /dev/usbdev2.2_ep81).
I was asking hypothetically, if the NUT code were changed to use /dev/
hiddev* instead of /proc/bus/usb or /dev/bus/usb.
