Okay, here's a problem I'm running in to. I have an NFS server that is
controlled via NIS for which hosts access the NFS mounts. I need to
give root access to an NFS client host machine, but /not/ the NFS

NFS mounts read only?
(Yeah I know it's a strange question, but time is pressing and I don't
have enough of it to google.) Any help would be appreciated.
By default NFS maps root to nobody. Only if the no_root_squash option
is used when exported does root from the client have root privileges on
the nfs filesystem.
Often this also means that root may not even access the nfs filesystem
at all.
HTH
"man exports" will give more info, specifically in in the User ID
Mapping section.
Let me see if I understand you, if I don't have 'no_root_squash' in my
/etc/exports file for a particular NFS share, then if I am root on the
/client/ I cannot access that NFS mount? If so, that's exactly what
I"m looking for.
