# activity, leaving all clients holding stale NFS filehandles,

# server for good, or for a long period of time, but not when the
# NFS server will be running again in short order. In this case,
# then "exportfs -r" will reread the xtab, and all the current
# clients will be able to resume NFS activity, *without* needing
# to umount/(re)mount the filesystem.
