Obviously not directly applicable, but I use nut and a cyberpower UPS
and the shutdown scheme it employs is that the master (controls the
UPS) commands everything else to shut down, then it begins shutdown,
and just before powering off it sends a command to the UPS which
causes a several second delay followed by a power off, and then it
powers off the host (which is otherwise shutdown already).
I need to re-read how exactly this is implemented.
