i would just copy the live system from the amiga forever dvd
mount and unpack 'knoppix' file
change contents to my needs and repack file
mkisofs and done.
i don't remember everything (did this for a knoppix cd) but:
- Mount the compressed KNOPPIX file.
insmod cloop file=home/KNOPPIX
mount -o ro /dev/cloop compressed/
- Copy the knoppix source to your working directory
cp -Rupv compressed/* source/
- Umount the compressed KNOPPIX image
iirc you need a prog to repack knoppix file, which i can't remember.
maybe someone know better
