# When restarting the NFS server, running "exportfs -ua" probably
# isn't what the user wants. Running it causes all entries listed
# in xtab to be removed from the kernel export tables, and the
# xtab file is cleared. This effectively shuts down all NFS
# activity, leaving all clients holding stale NFS filehandles,
# *even* when the NFS server has restarted.
#
# That's what you would want if you were shutting down the NFS
# 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.
