mlopes,
Problably you´re talking about the script I developed for remastrering your hd installed knoppix, which is posted at http://www.knoppix.net/forum/viewtopic.php?t=18222
AFAIK it works well for knoppix versions 3.7, 3.8 and 3.8.1, as well as kanotix 2005-02. I didn´t upgrade it to the newer versions due to lack of time, since I´m working on a new project called "Distro Maker", which is a collection of script you use to build a debian box almost from scratch, using the Morphix Base. It´s already available but in brazilian portuguese. As soon as I have it in english I´ll let everybody here knows.
Regarding your issue, since you´ve downloaded the 3.8 knoppix I would like to know if you´ve used the script with it and if it has presented some problems. If so, let me know exactly what they were and the specific knoppix version, as well as your amount of RAM and SWAP.
Cheers.
