I think the issue is that if a filesystem is put into /etc/fstab with
type = "bind" then it will show up in /etc/mtab as "bind" and if the
original filesystem is unmounted the "mount" output will not show the
correct type anymore (I tested this with "bind" and "reiserfs" on an
ext3 filesystem).

Cheers, Andreas
