Freeduc is a "run-from-CD" Linux distribution based on Knoppix and created by OFSET in France: "Until now - and probably for a while in most heads - the GNU/Linux system at school has been perceived as a good replacement of other proprietary servers. However the server is probably the least important thing in terms of freedom in a school network. It doesn't allow a teacher to share a workstation software with students. Supporting GNU/Linux in the workstation side can grant higher freedom and liberty between users in a school. Therefore, OFSET has setup Freeduc, a tool to help to list, to evaluate and to package only free - non GPL exclusive - edu soft."
