For networked environments (think NFS mounts and NIS). If distribution A
decides that the group mail is (say) GID 12, and distribution B decides
that is GID 8, what happens when you try to NFS mount /var/spool/mail from
a machine running A on a machine running B? All the files have the wrong
group. A base set of UIDs and GIDs is defeinitely needed.
