2 is an open source system development environment (or distribution build kit if you 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 decentralised development and a clean framework for spin-off projects and customised distributions.
