# This script is used to check and see if a fileserver is up 
# when a workstation boots. If server is not up the nfs shares
# are not mounted. This avoids long waits while the workstation
# tries to mount nfs shares listed in /etc/fstab if the file-
# server is not up. I run it from /etc/rc.d/rc.local on
# Slackware boxes. 
#
# Note that mounting shared directories like this instead of
# listing them in /etc/fstab may cause your system to hang at
# shutdown unless you umount them manually and early. To do
# that in Slackware I create a rc.local_shutdown script in
# /etc/rc.d. If this script is executable it will be run
# early from rc.0. For me that script looks like this:
# 	#!/bin/bash
#	# /etc/rc.d/rc.local-shutdown
#	# This script will be run at the beginning of
# 	# /etc/rc.d/rc.0 which is the script run for
# 	# level 0, i.e. shutdown.
#
#	umount /videos/archives
#	umount /videos
#	umount /var/backups
