When I KickStart a new workstation, it mounts its ks.cfg off
of an NFS server. Then, after the kickstart is done, the
new workstation reboots and everything -seems- fine.
Little did I know until my NFS server started to fail that
there were lingering mounts listed in /var/lib/nfs/rmtab.
BOTH the kickstart config mount and the redhat mount (for
the install) are lingering now in the xtab =and= rmtab files
on my NFS server.
We are aware of this problem and are trying to come up with the best solution.
I have added your bug to a list of feature requests.
