T2 System Development Environment

"T2 is not a common Linux distribution - it is a flexible open source System Development Environment or Distribution Build Kit if your are more familiar with that term. T2 allows the creation of custom distributions with bleeding edge technology. Currently the Linux kernel is normally used - but we are expanding to Hurd, OpenDarwin and OpenBSD - more to come. T2 started as a community driven fork from the ROCK Linux Project with the aim to create a decentralized development and clean a framework for spin-off projects and customized distributions."
