# File:         fix_automounts
# Description:  Remounts exported file systems from a machine
# Author:       Andrew DeFaria (defaria@cup.hp.com)
# Language:     Korn Shell
# Created:      Tue Apr 21 11:59:57 PDT 1998
# Status:       Experimental (Do Not Distribute)
# Modifications: Removed the grep "(everyone)". In the past file systems were
#               exported to everyone and that is no longer the case. This does
#               mean that this script might attempt to mount things it can't
#               but there is no easy way to ascertain if the current machine
#               is allowed to mount given showmount -e output, especially if
#               that output is a netgroup. I could check this via ypmatch
#               but that'll take yet more smarts...
