# output can be used by the restore vg command to recreate 
# the volume groups.  For example:
#	restvg -qf /vg_images/savevg.$VGNAME

rm -f /vg_images/savevg.*
rm -f /tmp/savevg
integer total_error=0

# 1) get the non-rootvg volume groups (vg)
# 2) get the logical volumes (lv) by vg's, remove the header
#    line, remove the unmounted & raw lv's, remove the nfs
#    mounted files and print the mount point.
# 3) save the mount point in /etc/exclude.$VGNAME
# 4) save the volume group information for each volume group,
#    while excluding the actual files, in /vg_images/savevg.$VGNAME
