LinuxDevCenter.com: Using and Customizing Knoppix [Nov. 20, 2003]: "You will need the following ingredients to bake your CD:
One Knoppix CD.
1GB of RAM: Don't worry if you don't have this much RAM; swap space will work just as well.
One PC with an existing Linux distribution installed and at least two partitions:
Partition 1, where you will develop the Knoppix CD. It must have at least 4GB of free space, although you'll need 5GB if you are short on RAM.
Partition 2, a 710MB empty partition.
The command-line utility create_compressed_fs, which can be copied from the Knoppix CD.
One kick list. This file lists packages that can be removed from the default distribution without 'breaking' dependencies.
Miscellaneous shell scripts: user-defined scripts facilitating development."
