It doesn't seem to be possible to mount the KNOPPIX image file in rw mode via cloop? I want to be able to access this the filesystem inside the image file at anytime because i don't want to have to extract/compile this file every time i want to make changes.

So how:
- can i mount the KNOPPIX image in rw?
- can i use an extracted and uncompressed filesystem sitting on a nfs share?
