adding a directory to a CD-image (.iso)

If I had to spec it out, I'd say, it needs to be able to modify an existing 
iso9660 image. Ideally, I'd just be able to mount the image as a file system 
and have my way with it (rm/mv/cp), but that would require kernel work.

A set of use-space tools like that provided by emulators/mtools for FAT 
filesystems would do fine.

The objective, again, is to preserve the original image's many options such 
as, in this example, vendors' records, copyrights, bootblocks, etc.

Maybe, growisofs (maintainers CC-ed) will offer that in the future?
