I don't know much about how isofs is laid out, but two points come to mind:
- On a read-only filesystem, you don't need a free/in-use bitmap.
- You also don't need indirect blocks, since each file could conceivably
be laid out linearly.
A truly read/write isofs would need to maintain the above - the first is
obvious, and the second is required to support independent writes from
more than one process.
So the question really is: "**can** the iso9660 filesystem code be made to
write iso9660 images as a general-purpose filesystem?"
