There are:

- /proc/mount does not contain the root device, but "mount" can transform
/dev/root into the current root device itself

- bind mounts are listed wrong:
mtab: /var/cache/apt/archives /var/www/deb-archive/debian none rw,bind 0 0
mount: /dev/hda6 /var/www/deb-archive/debian ext3 rw 0 0

- loopback mounts are broken
mtab: /mnt/hdb/31/cdimages/potato1.iso /mnt/iso/potato1 iso9660
ro,loop=/dev/loop0 0 0
mounts: /dev/loop0 /mnt/iso/potato1 iso9660 ro 0 0

- Diskquota quota options are not reflected

Most of those options can be easyly fixed in kernel space, some others will
not affect most users.

My oppinion is, we should support the link if somebody feels like it will
work. In fact, we should support read only root.
