A new Ubuntu derivative is under development. It's called Gnubuntu and only uses software which follows the Free Software Foundation (FSF) guidelines. Mark Shuttleworth, founder of the Ubuntu distribution, agreed this with GNU-founder Richard Stallman.
Stallman supports the idea, but isn't happy with the name. Anyway, the name Gnubuntu will be kept, the corresponding domain gnubuntu.org is already registered - but with no content on it yet.
The new distribution will only contain Ubuntu packages, which follow the Free Software Foundation guidelines. Most of the linux distributions already consist mostly of free software, but they also contain binary packages without the corresponding source code or commercial applications. One exception is the Ututo distribution, which already consists only of free software completely. Shuttleworth wants to ask these developers to join the Gnubuntu development.
