Thanks for your suggestions. Indeed we're using Debian Live ( and their tool is automatically using squashfs. The real DoudouLinux system sizes around 2 GB. However most of this space is taken by data files of a couple of educational games. This is why our development version is still far from fitting a single CD. We have to work on reducing these data files.

Concerning the base distribution, there are several reasons why we're using Debian:

  • it's very stable and reliable
  • it has a very large software offer, maybe the largest
  • it is available on many different hardware platforms (we want to go on ARM and others probably)
  • it is translated in many languages

However Puppy's remastering tool may be interesting, I must say I've never looked at this distro. Note that we're planning to release a DoudouLinux DVD in the future to ship more applications to people having a large download bandwidth – which is not the case everywhere on earth.

I have used a wonderful lightweight Live distro called PuppyLinux which includes a large amount of software onto a regular CD. It also offers the ability to dynamically download additional programs as well as an easy way to remaster your own customized CD.

I believe it accomplishes including a large amount of programs via use of the Squash File system which is a compressed read-only filesystem for Linux. Maybe worth looking into to get more programs on your CD:

It may also be worth looking at using puppylinux as a base to remaster doudoulinux. Just a thought since it accomplishes all of the same goals you have with using debian. It is extremely lightweight and optimized for older hardware and has remastering capabilities built in. It has spawned a large number of specialized distros such as browserlinux.
