Of course there are some restrictions.

What I meant to say was that code of the various filesystems currently
assumes that the data on the media is somewhat consistent.  Since the
intention is that Joe User can mount some arbitrary floppy (or zip disk,
or ...), the in kernel filesystem code needs to check any data it
reads off the media for plausibility.
