PREAMBLE
- This script was done using the Knoppix 5.1 boot cd.
- This has been updated by: SNIa 20:43, 8 Apr 2007 (GMT)
- Knoppix Sources http://debian-knoppix.alioth.debian.org/
- Please note that this howto is not without a few flaws, please revise and suggest as necessary.
CONVENTIONS USED
The following conventions are used, within dotted box:
Commands & paramaters Text within this dotted box can be put directly into a script
Some commands are linked, if you require further explanation of the command or parameter click the link. Example shown below:
apt-get
GETTING STARTED
All dotted boxes below are to be put into a script, or into a shell directly.
Setup The Environment
Hash Bang
- As required at the beginning of a script (UNIX), a Hash Bang
#!/bin/bash
You will need cloop-utils and KNOPPIX_V5.1.0CD-2006-12-30-EN.iso
apt-get cloop-utils wget http://www.kernel.org/pub/dist/knoppix/KNOPPIX_V5.1.0CD-2006-12-30-EN.iso

Now setup the environment, make directories, run the debootstrap command and then change root. You will get lots of errors that it can't find necessary files (mostly in /usr/share...) on this next step; you can safely ignore them.

We're basically done but if you want to make any changes with how Knoppix starts or what comes up when it starts, this is the place to do it. You could just copy stuff to /etc/skel so that you have it on your new cd under /home/knoppix
Build The CD
- Make the compressed KNOPPIX CLOOP file
mkisofs -R -U -V "Knoppix" -publisher "yourname" -hide-rr-moved \ -cache-inodes -no-bak -pad ${NEWSRCDIR} | nice -5 \ /usr/bin/create_compressed_fs - 65536 > ${MASTERDIR}/KNOPPIX/KNOPPIX
Create the knoppix.iso file
mkisofs -pad -l -r -J -v -V "KNOPPIX" -no-emul-boot -boot-load-size 4 \ -boot-info-table -b boot/isolinux/isolinux.bin -c boot/isolinux/boot.cat \ -hide-rr-moved -o ${KNXROOT}/knoppix.iso ${MASTERDIR}
Try it out
qemu -m 128 -cdrom ${KNXROOT}/knoppix.iso -boot d
Burn it
k3b ${KNXROOT}/knoppix.iso
