: T2 SDE :

T2 System Development Environment

... more than a distribution next generation.

T2 SDE is not just a common Linux distribution - it is a flexible Open Source System Development Environment or Distribution Build Kit (others might even name it Meta Distribution). T2 allows the creation of custom distributions with state of the art technology, up-to-date packages and integrated support for cross compilation. Currently the Linux kernel is normally used - but the T2 SDE is being expanded to Minix, Hurd, OpenDarwin, Haiku and OpenBSD - more to come.
