sinking,
Two remarks:
1 - If this is the command for generating the KNOPPIX compressed iso, it's wrong! This will generate an iso whithout headers (iso level 2 or level 4), like when we generate the main and minimodules on a Morphix distro. The correct command would be mkisofs -R -hide-rr-moved -cache-inodes -pad source/knoppix | nice -5 create_compressed_fs - 65536 > master/KNOPPIX/KNOPPIX;

2 - If you're trying to remaster your HD installed knoppix, you'd better try the script I made available at http://www.knoppix.net/forum/viewtop...18222&start=20. If you're gonna use it, please follow closely the instructions given on the posts. The last version available is knxhdremaster_en-1.4.sh.
Good luck!
