How should I kill the automounter?
Always give automounter a “friendly kill” never kill -9. This will allow the automounter to clean up all those symlinks and umount those file systems. Busy mounts are NOT left alone, after a valiant attempt to umount. What happens is this: automount spawns a child to service any NEW requests to the automounte and the parent spends its time trying to umount all busy mounts. Note: if you do a kill -9 at this point you WILL have to clean up your mess (remove symlinks, umount old automount NFS mounts, and clear up /tmp_mnt).
