MirOS BSD – a secure operating system from the BSD family for 32-bit i386 and sparc systems. It is based on 4.4BSD-Lite (mostly OpenBSD, some NetBSD®). The MirPorts Framework is a portable ports tree to facilitate the installation of additional software. The project also releases some portable software: mksh, a pdksh-based shell; PaxMirabilis, an archiver for various formats; MirMake, a framework for building software; MirNroff, an AT&T nroff based man page (and text document) formatter; MirCksum, a flexible checksumming and hash generation tool; and some more.
MirOS is available as a BSD flavour which originated as an OpenBSD patchkit, but has grown very much on its own, though still being synchronized with the ongoing development of OpenBSD, thus inheriting most of its good security history. This variant is also called “MirBSD”, but the usage of that word to denote MirOS BSD (plus MirPorts) is deprecated.
MirOS started after some differences in opinion between Theo de Raadt, the OpenBSD project leader, and Thorsten Glaser, who is now our lead developer. The main maintainer of MirPorts is BennySiegert. There are several more persons working as contributors on the project.
The latest release of MirOS is #10semel released March 16, 2008; the latest preview of MirBSD-current is 10uB4-20160117 released January 17, 2016.
