PUD Build Kit
"PUD GNU/Linux project provides a set of live CD's build tools, including configure files, build script and packages list.
You have exactly the same tools that developers use. Hope this may help you customize and make your own live CD quickly and easily. [...]
This script will install base system, chroot to install more packages, config, cleanup unneeded files, compress filesystem, make the .iso image and start qemu to test. The whole files will be put into ../builddir/pud-YYYYMMDD-HH/, and the image file is ../builddir/pud-YYYYMMDD-HH.iso ."
