  I'm pretty sure it has something to do with esoteric features of the
various Compact Disc specifications.  CDs can have multiple sessions, each
with multiple tracks.  An ISO-9660 filesystem can have multiple namespaces,
and there does not have to be a one-to-one match of every file in every
namespace.  Plus the whole boot catalog thing, which is "outside" the
"regular" ISO-9660 filesystem, but still part of it.  How the heck do you
present that as a single

	/dev/cdrom

device?  :-)

  I know it's made a difference with Red Hat Linux CDs (back when there
*was* a Red Hat Linux) made from MD5-verified images, so it isn't a copy
protection thing.
