Gentoo to celebrate tenth birthday with new live DVD
Born as Enoch Linux in 1999, the distribution has slipped a bit in popularity over the years, yet it still provides a solid foundation for other distros. Like Debian was supplanted by Ubuntu, Sabayon - which is Gentoo-based - maintains a spot in the top ten on Distrowatch.
The anniversary build will be the first (and likely only) Gentoo release of 2009. A sneak peak of the release is already available via the US and EU mirrors for those who want to check it out now. As Phoronix points out, there aren't yet any 10th anniversary customizations in the snapshot builds. You'll just be getting a look at the current default packages for now.
