No. The 'getpwnam(nut): Success' should not be displayed by the driver as
far as I can tell. Throughout the sources, the word 'getpwnam' is only
used to display a fatal error when NUT isn't able to locate a userid, in
this case for 'nut'. Where this 'Success' is coming from, is beyond me.

My guess would be that the user 'nut' doesn't exist. Try if adding '-u
root' to the list of commandline parameters solves this (temporarily).
Sometimes 'id nut' may be helpful too.
