Mastering a live CD - the right way (TM)

Today Knoppix-Remastering:
Get Knoppix-ISO and remove files
Makes no sense even with bittorrent
Tomorrow Knoppix-Mastering:
"Basic-Knoppix" in chroot and adding packages
Integrate Knoppix build system into Debian
Might be a Custom Distribution for itself
Creation and customisation of live CDs from native Debian mirror
debootstrap
Install Knoppix stuff into chroot environment
Customise chroot environment for intended purpose
Create ISO image from chroot environment (as done before)
Perhaps make use of debix
Portable to other architectures (PowerPC)
