# Device        Mountpoint    FStype    Options        Dump    Pass#
/dev/label/swap        none        swap    sw        0    0
/dev/label/rootfs    /        ufs    rw        1    1
/dev/label/backups    /backups    ufs    rw        2    2
/dev/label/home        /home        ufs    rw        2    2
/dev/label/tmp        /tmp        ufs    rw        2    2
/dev/label/usr        /usr        ufs    rw        2    2
/dev/label/var        /var        ufs    rw        2    2
/dev/acd0        /cdrom        cd9660    ro,noauto    0    0
linproc  /usr/compat/linux/proc linprocfs rw 0 0

this is ad12; ad6 is the same - I guess I hae to get rid of those labels
in ad6 but am not sure if I need to use glabel to remove them or if just
editing fstab will do it?
