Not just that, it also mean that loopback devices won't be automatically
unallocated when used in loopback mounts, because /proc/mounts does not
store all the required info.

Parts of /etc/mtab:
===================
/mnt/hdb/31/cdimages/potato1.iso /mnt/iso/potato1 iso9660 ro,loop=/dev/loop0 0 0

The same from /proc/mounts:
===========================
/dev/loop0 /mnt/iso/potato1 iso9660 ro 0 0

This comes up every now and then and deserves a FAQ entry (if it hasn't one
already).
