Debian

From Hackstop

The Debian Project [1] (http://www.debian.org)

"The Universal Operating System"

The truest and most complete GNU distribution in most people's view. [RMS] does not see it as pure enough, on principle, but defers GNU Project need for completion in favour of Debian GNU/Linux.

Debian supplies the foundation tools for many other popular distributions - collectively in size, a development team second only to RedHat and four times bigger than SuSE (apparently).
