Yeah, it's a strange situation.  I have an NFS server that has exported 
/home/users.  One of the machines (client A) that mounts that NFS share 
is being handed to another group who needs root access.  Because of the 
fact that we have other user accounts in /home/users I cannot let 
someone else have root access on Client A.  What I want is to be able to 
keep that NFS mount on Client A, but not let root on Client A access 
that NFS mount.  Does that clear it up a bit? 

I got another reply mentioning no_root_squash, but I just got in and I'm 
not yet ready to look into that option, at least not until my fisrt cup 
of coffee.
