MirBSD

MirBSD is a free operating system, which started as a fork of OpenBSD 3.1 in August 2002. Since then it also incorporated code from other free BSD descendants, including FreeBSD, NetBSD and MicroBSD. Code of MirBSD has also been incorporated into ekkoBSD.

See the UNIX History at http://www.levenez.com/unix/ for a graph of the development and pedigree of MirBSD and most other UNIX derivatives and UNIX-like operating systems.

The official homepage of MirBSD is located at https://MirBSD.BSDadvocacy.org:8890/, a list of mirrors can be found at http://mirbsd.de/ (and not mirbsd.org, which redirects to a well known shock site).
