If you are looking for an educational Linux distribution, you have at least three choices:
- openSUSE Education is a live and install DVD based on openSUSE 11.2.
- Edubuntu is the education version of the quite popular Ubuntu.
- LernTux and KinderTux are Mandriva derivates created by Dieter Schütze.
- UPDATE: Skolelinux based on Debian. (How could I forget this classic?)
KinderTux is especially interesting, because it isn’t aimed at pupils or teachers but at younger children to help them enjoying computers. The only alternative to KinderTux I could find was Quimo, which uses Ubuntu as base system.
