"With the goal of bringing more experimental development to the OpenBSD code base, a few developers have announced a fork named Bitrig. According to their FAQ, Bitrig aims to build a small system targeting only modern hardware and "be a very commercially friendly code base by using non-viral licenses where possible." Their first step toward that goal was removing GCC in favor of LLVM/Clang. The project roadmap shows their future goals as adding FUSE support, improving multiprocessing, porting the system to ARM, and replacing the GNU C++ library with LLVM's."
