There's no benefit to putting a filesystem in a squashfs image for the
original poster.

The reason the Fedora liveCD does it is because cloop is not upstream,
and they can't use a squashfs instead of ext3 because squashfs doesn't
support extended attributes (read: SELinux).

As I say, squashfs is irrelevant to this discussion.
