Obviously the md5 itself can't be part of the data of which it's
calculated. In case of an iso9660 filesystem you know its size, it would
be easy to append another block with the md5 sum as first line, null
padded.
Whatever you do, make always very sure you calculate md5 sums of
filesystems over exactly the size of the filesystem, not less or more.
Otherwise you might end up where you can't quite remember on how much
of your CD you calculated the original sum...
