There is an alternative to the Linux From Scratch project in custom building a Linux distro with the T2 SDE.
Rene Rebe has announced the release of T2 SDE 8.0, a distribution build kit designed for advanced Linux users who wish to build custom distributions: “After years of development we are proud to announce the availability of the new T2 stable release, version 8.0. This release received updates across the board, while a major working target was to further improve cross compilation, and all official ISO images are now fully cross-built. Over 10,000 Subversion revisions indicate the magnitude of the release, with over 200 new packages, new features and various other improvements and fixes. User visible changes: GCC 4.5.0, glibc 2.11.2, X.Org 7.5, preliminary support for LLVM/clang and MinGW/Win32.” Visit the project’s home page to read the release announcement
