    Modify /etc/fstab to include the line:

    /dev/hdg1 /mnt/flash vfat ro,umask=007,users,noauto,gid=109 0 0

    (gid is the group id that includes the users you want to have access to
    the CF card.)

    Any user in the group (and, of course, root) can mount the drive with a
    simple "mount /mnt/flash", but once mounted, only that user (and, of
    course, root) can umount with "umount /mnt/flash" man fstab for more
    details.
