there are some notes in the list archives, but apparently Google

If you use Fink, you could probably use the nut.info file here:
http://www.ghz.cc/cgi-bin/viewcvs.cgi/dev/eda/finkinfo/ups/nut.info
(it's for an older version of NUT, but the same principles apply)

Either way will work, or you can just cheat and use the 'nobody'
account.

Since you would be setting up the Mac as a slave, you wouldn't have to
muck with the system's shutdown scripts to send the power-off command
to the UPS. You can do a 'shutdown -h +1', but it won't really
inform
the users of the impending shutdown.

Part of the problem is that Apple keeps improving their
startup/shutdown system, but they leave out important bits of
documentation. SystemStartup scripts are effectively obsolete as of
10.4, and launchd's control socket functionality is not documented at
all (from what I can tell). If you find out anything else we'd love to
hear about it on the list.
