Diskless NFS systems with no local harddisk, where all directories are
stored on a server.

No, I don't know if storing sendmail queues on NFS is a good idea, it
probably isn't; another package might be more appropriate.

No, the directories aren't "shared", but you don't want UIDs to
be different on the client and the server, not only could it create
security issues, but also cause much confusion too.

This also raises a number of other issues like "should postfix running
on the server really be able to access the spool directory of each of
NFS client?", but I don't want to get into that right now; SE-Linux
might be the complete answer, eg. only allow the NFS server process
access to these files on the server.
