On my Linux box I don't use SIGPWR at all for handling a UPS. The UPS
program just uses the normal shutdown commands when it needs to schedule
or abort a shutdown. This approach seems to work fine. So I don't think
SIGPWR is really necessary in order to use a UPS.

That's not to say whether it should be added, just a comment which may or
may not be interesting.
