Ahem. It's just "Linux", thank you very much. That's the name Linus gave his kernel; it's Stallman, the man who cares about "freedom", who wants go around renaming other people's work.

If you really want to come up with a contributors-aware name for a complete Linux distribution, the correct one would be "AT&T/Berkeley/MIT/GNU/Torvalds/AndManyManyOthers/Linux". It ain't just GNU inside there.
