Can an iso image file be modified?


I created an iso image file called testfile using mkisofs -r. I then mounted it with
"mount -t iso9660 -o loop,rw testfile /mnt/somewhere" but still could not write to
it. What is the reason for that? Is there any way an iso image can be modified?

I have searched LQ and found contradictory answers:

Try copying the iso9660 files to another file system type, say ext2. Modify the copied files and then use mkisofs to recreate the iso image.

thank you for your responses.

jailbait: yes, i suppose that's the way to do it. it looks like the trouble i was
having is due to the fact that iso9660 is a read-only filesystem.

heema: nice to know such things exist.
