Why not simply boot with an ISO 9660/RockRidge filesystem as root?
Unlike some other operating system, Linux can use an ISO 9660
filesystem as root with no problems...

There's another reason why most distribution makers would prefer to use
a ISO 9660/RockRidge filesystem format for CD's. Other operating
systems can read ISO 9770 CD's.

So for example, if you're currently running Windows, and you want to
upgrade OS's, it's useful if you can mount the distribution CD long
enough to browse the disk's documentation, or download boot floppy
images (if their computer doesn't support the El Torito format), etc.

So while I don't think the idea of a bootable ext2 cd is complete
nonsense, I'm not sure it would actually be used and be useful for
distribution maintainers.
