Pretty easy to do using the loopback device.  I think losetup is
Red Hat-ism, but you get the idea:

# dd if=/dev/zero of=/c5/diskimage.ext2 bs=1k count=9000
# losetup /dev/loop0 /c5/diskimage.ext2
# mke2fs /dev/loop0
# mount -t ext2 /dev/loop0 /mnt/cdrom
# find dir ... | cpio -pdm /mnt/cdrom
# umount /mnt/cdrom
# losetup -d /dev/loop0

# cdrecord -v /c5/diskimage.ext2
# mount -t ext2 -o ro /dev/cdrom /mnt/cdrom
