Can some one write brief instructions on how to use this sort script for sorting so we can actually use it. In addition, where it syas "KNOPPIX.build" in the script, is that the location of your KNOPPIX chrooted environment ?.

Well no it isn't since they do not use chroot to remaster! You must actually boot into your remastering environment. Now I have not yet figured out the sorting scripts either and I also know that it is possible to use only one partition for remastering but I use 2. I am fully aware that there is still much room for improvement in this method. Also notice that I use Kanotix so adjust accordingly for Knoppix.

This is very easy to do and here's how I do it. (Thought about adding this to the wiki but the docs there get hosed up really quickly!!) Anyway........

#Substitue your own drives for /hda11 & /hda12 throughout.
#/hda11 will be the SOURCE direcotory- the directory we install Kanotix to.
#/hda11 is: 1 partition of 3G (or more if you want to make a dvd)
#/hda12 will be the BUILD directory containing the compressed KNOPPIX fs,
# boot.img & final image (kanotix.iso).
#/hda12 is: 1 partition of 1G (more if you're making a dvd).
_______________________________
#BOOT & INSTALL KANOTIX
sudo kanotix-installer
use /dev/hda11 for /
Select 'knoppix' type install!
edit .knofig to install grub to partition
(of course you can install to mbr if you don't wish to boot another OS)
______________________________
#SET UP BUILD DIRECTORY

mount /dev/hda12 /mnt/hda12
mkdir /mnt/hda12/KNOPPIX
cp /cdrom/KNOPPIX/boot.img /mnt/hda12/KNOPPIX

_______________________________
#EDIT YOUR BOOT LOADER
#EXAMPLE: /boot/grub/menu.lst entry

REBOOT INTO YOUR REMASTERING ENVIRONMENT>>>
Be sure to use:

IF you intend on removing KDE and/or IceWM
or boot into run level 2

DO KANOTIX YOUR WAY
su

rm -rf /etc/skel

TWEAK THE DESKTOP
#Your configurations are saved in /home/knoppix

REBOOT INTO YOUR PRIMARY OS
su
mount /dev/hda11 /source
chroot /source

Now you need to clean up. I have a customized version of a script I found somewhere (sorry I forget where) it's at the bottom (maybe by charan??)
ctrl+d (to leave chroot)

#MAKE THE ISO IMAGE

/build# mkisofs -l -r -J -V "KanotiXFCE4" -b KNOPPIX/boot.img -c KNOPPIX/boot.cat -o kanotixfce4.iso /build

Of course you must make adjustments for Knoppix!! Here's the script:

#!/bin/sh
umask 022

/etc/init.d/autofs stop

# remove only "temporary" or saved files in the given directories
nuke(){
for i in `find "$@" -name \*.gz -o -name \*.bz2 -o -name \*.0 2>/dev/null`; do
rm -f "$i"
done
}

# set all files in the given directories to a length of zero
zero(){
for i in `find "$@" -type f -size +0 -not -name \*.ini 2>/dev/null`; do
:> "$i"
done
}

So hopefully this thread is the start of a very complete and very easy remastering howto. The chroot method is ok if you just want to make some small changes but if you're not running the same kernel you have problems plus other unnecessary issues to deal with.

Of course you can just boot Knoppix, cd KNOPPIX and do cp -a * /mnt/point and then boot into it as well.
