I wrote a mostly command based but fully complete manual to remaster the knoppix DVD. Here it is:

The first WORKING!! Knoppix DVD remaster Guide WITH X-Desktop. (c) 2005 by ArkoN <www.ArkoN.ch>

Boot your knoppix with a window manager(thats needed for a working XF86Free-Config-4 file)

The DVD Filesystem CANT!!! handle files bigger than 2 GB

make a 25GB ext2 Partition and name it sda1(or whatever you want) then remaster it with these commands:

su -

mount -rw /dev/sda1 /mnt/sda1

mkdir /mnt/sda1/knx

cd /mnt/sda1/knx
dd if=/dev/zero of=swapfile bs=1M count=5500
mkswap swapfile
swapon swapfile

mkdir -p /mnt/sda1/knx/master/KNOPPIX
mkdir -p /mnt/sda1/knx/source/KNOPPIX
mkdir -p /mnt/sda1/knx/source/KNOPPIX2

cp -Rp /KNOPPIX/* /mnt/sda1/knx/source/KNOPPIX
cp /cdrom/KNOPPIX/KNOPPIX2 /mnt/sda1/knx/master/KNOPPIX/

cp /cdrom/index.html /mnt/sda1/knx/master/

cd /cdrom && find . -size -15000k -type f -exec cp -p --parents '{}' /mnt/sda1/knx/master/ \;

cp /etc/dhcpc/resolv.conf /mnt/sda1/knx/source/KNOPPIX/etc/dhcpc/
cp /etc/X11/XF86Config-4 /mnt/sda1/knx/source/KNOPPIX/etc/X11/

vi /mnt/sda1/knx/source/KNOPPIX/etc/X11/Xwrapper.config
change "allowed_users=console" to "allowed_users=anybody"
/etc/init.d/xsession stop

// Now we start the chroot into the directory
chroot /mnt/sda1/knx/source/KNOPPIX

mount -t proc /proc proc

// check with the command date your date. If its wrong set it right, read the manpages (example: date -s 15:14)
// If you install some programms, you dont have troubles.

chmod 777 /tmp

cd /home

cp -R /etc/skel knoppix

chown -R knoppix:knoppix knoppix/

//do this not remote!!
su knoppix


//make changes now

// apt-get remove --purge gnome*
// change your x settings etc.

/etc/init.d/xsession stop

su -

cd /home

rm -rf /etc/skel

mv knoppix/ skel

mv skel /etc

chown -R root.root /etc/skel

apt-get clean

apt-get autoclean

rm -f /etc/skel/.bash_history

rm -f root/.bash_history

rm -f /etc/dhcpc/resolv.conf

rm /etc/X11/XF86Config-4

chmod 555 /tmp

vi /etc/X11/Xsession.d/45xsession
go to line 128 (with escape then type 128)
change these lines:
rsync -Ha --ignore-existing /etc/skel/{.kde*,Desktop} $HOME/ 2>/dev/null
rsync -Ha --ignore-existing /etc/skel/ $HOME/ 2>/dev/null

umount /proc


mount -t proc /proc proc

mkisofs -R -U -V "KNOPPIX.net filesystem" -publisher "KNOPPIX www.knoppix.net" \
     -hide-rr-moved -cache-inodes -no-bak -pad /mnt/sda1/knx/source/KNOPPIX \
  | nice -5 /usr/bin/create_compressed_fs - 65536 > /mnt/sda1/knx/master/KNOPPIX/KNOPPIX

cd /mnt/sda1/knx/master

find -type f -not -name md5sums -not -name boot.cat -not -name isolinux.bin \
   -exec md5sum '{}' \; > KNOPPIX/md5sums

   -hide-rr-moved -o /mnt/sda1/knx/knoppix.iso /mnt/sda1/knx/master

Now your iso is there:

And ready to burn, hf
