Résumé
If you are asked about it, say that you ignore it. You can give just a hint: images of gnus and penguins can be seen here and there.
One could legitimally worry about the difficulty for students to adapt themselves to the environement of Freeduc-CD, which relies on a Linux kernel, and features the graphic environment Xfce, and does not look like the Windows operating system spread around on most of the machines of the school.
The educational applications which are found now for the system GNU/Linux achieve such a maturity level that our students get accustomed with them most quickly. They use to switch without difficulty from Nintendo to Sony game machines, and switching from Windows to GNU/Linux is no more a problem. If we learn to teach with various environments, we can insist on the essential things and not on acessories. In non-specialized trainings, it is important to do so.
