The Sortix operating system

Sortix is a small self-hosting Unix-like operating system developed since 2011 aiming to be a clean and modern POSIX implementation. There's a lot of technical debt that needs to be paid, but it's getting better. Traditional design mistakes are avoided or aggressively deprecated by updating the base system and ports as needed. The Sortix kernel, standard libraries, and most utilities were written entirely from scratch. The system is halfway through becoming multi-user and while security vulnerabilities are recognized as bugs, it should be considered insecure at this time.Sortix 0.9 was released on December 30, 2014. It is a very considerable improvement upon Sortix 0.8 and contains significant improvements all over the base system and ports. The previous release made Sortix self-building and this release works hard towards becoming fully self-hosting and installable. Several real-life prototype self-hosting installations of Sortix exists right now, I expect the following 1.0 release to make real Sortix installations available to the general public.
