#Dear netters,
#
#since I'm a little bit unfamiliar with the hidden secrets of rpc-calls
#I'd like to avoid running pcnfsd under root's uid. Will it loose any 
#functionality when running under user.none (right - this is Domain/OS ) ?

PCNFSD invokes setreuid() and setregid() in order to make sure that
any print files are owned by the correct user, and (depending on
how your spooler works - I don't know DOMAIN/OS) have the correct
banner on them. I assume that you need what X/Open calls "appropriate
privileges" to execute these calls. This usually means running as
root.
