Almost, but not quite.  Think of "dd" as doing what "fdisk" would
do to a hard disk: it creates the empty space that can then be
set up with your directory structure.  So this is the first
command that you need to issue, not the last.  Use something more
like:

  $ dd if=cdr.img of=/dev/loop0
  $ mkisofs -afvr -o cdr.img <directory>
  $ losetup -e des /dev/loop0 cdr.img

I don't know anything about mkisofs or losetup and their options,
so you're on your own there.  But "dd" definitely _must_ be the
first thing that you invoke in that sequence.

Good luck!

Cheers,
