I find that the automounter lacks imagination at times. This makes it
more inflexible than it needs to be. Fortunately the authors provided a
work around in the form of program mounts. I use these two entries in my
amd.map file:
msdos0 type:=program;fs:=${autodir}/${key};\
mount:="/sbin/mount mount ${fs}";\
unmount:="/sbin/umount umount ${fs}"
ufs0 type:=program;fs:=${autodir}/${key};\
mount:="/sbin/mount mount ${fs}";\
unmount:="/sbin/umount umount ${fs}"
and these two entries in /etc/fstab:
/dev/da0s1 /.amd/msdos0 msdos rw,longnames,noauto 0 0
/dev/da0s2e /.amd/ufs0 ufs rw,nosuid,nodev,noauto 0 0
To get around problems that I have with amd. A little hackish? Yes but
you get complete control over how your filesystem is mounted. The ufs
entry works around the problem of the automounter never timing out a ufs
mount even if you use amq -u.
