This is a small lab-type setting but I'm trying to merge two sets of
machines set up by different groups to have a common home directory
server that all the others automount.  The number of users is small
enough that I'll just 'usermod' them into the same uid numbers, but I
don't see why it is worth running the idmapd daemon at all, when all
it does is map everyone to nobody if you forget to set the domains
identically.   And after fixing the uids to match, is there any
advantage to nfsv4 at all?
