Other Help Topics :: Extracting the KNOPPIX file
I order to extract the knoppix in DSL .9.2 you need to update the cloop-utils pacakge to an unstable debian version file . do this
boot cd
root shell
dpkg-restore
cd /etc/apt
add unstable or testing to your apt sources lsit
vi sources.list
delete the first # you see
save
apt-get update
apt-get install -t testing cloop-utils
now you can use
mkdir /mnt/hda1/files
mkdir /mnt/hda1/openfiles
extract_compressed_fs /mnt/cdrom/KNOPPIX/KNOPPIX > /mnt/hda1/files.iso
mount -o loop /mnt/files.sio /mnt/hda1/files
cp -a /mnt/hda1/files/* /mnt/hda1/openfiles
