The use of PAM would allow the use of local or centralized network
accounts for NUT access, but I don't think that should be a
requirement. Create a system account with nut privileges _only_ would
be a hassle to users.

Well, I don't think exposing information by default on a network is
ever a good idea. Even if that information seems innocent at first, at
least the fact that everyone can interact more with the server could
make small security bugs become critical.
