You could leave out the persistent superblock.
But you'd have to make the filsystem you put on the CDs span all the CDs. I
don't know if you can make a ISO filesystem that large, but if not, you'd have
to use something which is not optimized for the very slow seek times of a CD,
and you just might end up with something holding 2 G of read-only
incredibly-slowly-accessible data.
Even if you could use ISO, it would be a little trouble creating the filesystem
image to put on the CDs (doable indeed, but more trouble than usual). What
about just mounting the three CDs in a directory structure such as
cdrom/disk[123]/ ?
Still, it's an experiment, and it would have some hack value. But besides from
that I seriously doubt that RAID'ed CDs would be worth the effort.
