MirOS BSD (originally called MirBSD) is a free and open source operating system which started as a fork of OpenBSD 3.1 in August 2002. [3] It was intended to maintain the security of OpenBSD with better support for European localisation. Since then it has also incorporated code from other free BSD descendants, including NetBSD, MicroBSD and FreeBSD. Code from MirOS BSD was also incorporated into ekkoBSD, and when ekkoBSD ceased to exist, artwork, code and developers ended up working on MirOS BSD for a while.

Contents

Unlike the three major BSD distributions, MirOS BSD supports only the x86 and SPARC architectures.

One of the project's goals was to be able to port the MirOS userland to run on the Linux kernel, hence the deprecation of the MirBSD name in favour of MirOS.

History

MirOS BSD originated as OpenBSD-current-mirabilos, an OpenBSD patchkit, but soon grew on its own after some differences in opinion [3] [4] between the OpenBSD project leader Theo de Raadt and Thorsten Glaser. Despite the forking, MirOS BSD was synchronised with the ongoing development of OpenBSD, thus inheriting most of its good security history, as well as NetBSD and other BSD flavours. [5]

One goal was to provide a faster integration cycle for new features and software than OpenBSD. According to the developers, "controversial decisions are often made differently from OpenBSD; for instance, there won't be any support for SMP in MirOS". There will also be a more tolerant software inclusion policy, and "the end result is, hopefully, a more refined BSD experience". [6]

Another goal of MirOS BSD was to create a more "modular" base BSD system, similar to Debian. While MirOS Linux (linux kernel + BSD userland) was discussed by the developers sometime in 2004, [7] it has not materialised.

Features

The most important differences to OpenBSD were: [9]

Cooperation

Aside from cooperating with other BSDs, submitting patches to upstream software authors, and synergy effects with FreeWRT, there was an active cooperation with Grml both in inclusion [11] [12] and technical [13] areas. Other projects, such as Debian [14] are also fed with MirSoftware.

MirPorts

MirPorts was a derivative of the OpenBSD ports tree and was developed by Benny Siegert. MirPorts does not use the package tools from OpenBSD written in Perl, but continues to maintain the previous C-based tools. New features are in-place package upgrades and installing a MirPorts instance as a non-root user. Unlike OpenBSD ports, MirPorts are not tied to specific OS versions and even on stable releases using the newest version was recommended. MirLibtool was a modified version of GNU libtool 1.5 installed by MirPorts to build shared libraries in a portable way.

Multiple platforms are supported "out of the box":

Following the MirOS BSD policy of faster software availability to the user, many ports removed for political reasons in OpenBSD (e.g. all the DJB software or the Flash Plugin) have been kept in MirPorts and can continue to be used. MirPorts was intended to be a place for unofficial or rejected OpenBSD ports.

The Common Desktop Environment (CDE) is a desktop environment for Unix and OpenVMS, based on the Motif widget toolkit. It was part of the UNIX 98 Workstation Product Standard, and was for a long time the Unix desktop associated with commercial Unix workstations. It helped to influence early implementations of successor projects such as KDE and GNOME, which largely replaced CDE following the turn of the century.

Debian, also known as Debian GNU/Linux, is a free and open source Linux distribution, developed by the Debian Project, which was established by Ian Murdock in August 1993. Debian is the basis for many other distributions, such as Ubuntu, Linux Mint, Tails, Proxmox, Kali Linux, Pardus, TrueNAS SCALE, and Astra Linux.

A Linux distribution is an operating system made from a software collection that includes the Linux kernel and often a package management system. They are often obtained from the website of each distribution, which are available for a wide variety of systems ranging from embedded devices and personal computers to servers and powerful supercomputers.

Darwin is the core Unix-like operating system of macOS, iOS, watchOS, tvOS, iPadOS, audioOS, visionOS, and bridgeOS. It previously existed as an independent open-source operating system, first released by Apple Inc. in 2000. It is composed of code derived from NeXTSTEP, FreeBSD, other BSD operating systems, Mach, and other free software projects' code, as well as code developed by Apple.

<span class="mw-page-title-main">GoboLinux</span> Linux distribution

GoboLinux is a Linux distribution whose most prominent feature is a reorganization of the traditional Linux file system. Rather than following the Filesystem Hierarchy Standard like most Unix-like systems, each program in a GoboLinux system has its own subdirectory tree, where all of its files may be found. Thus, a program "Foo" has all of its specific files and libraries in /Programs/Foo, under the corresponding version of this program at hand. For example, the commonly known GCC compiler suite version 8.1.0, would reside under the directory /Programs/GCC/8.1.0.

DragonFly BSD is a free and open-source Unix-like operating system forked from FreeBSD 4.8. Matthew Dillon, an Amiga developer in the late 1980s and early 1990s and FreeBSD developer between 1994 and 2003, began working on DragonFly BSD in June 2003 and announced it on the FreeBSD mailing lists on 16 July 2003.

Portage is a package management system originally created for and used by Gentoo Linux and also by ChromeOS, Calculate, Sabayon, and Funtoo Linux among others. Portage is based on the concept of ports collections. Gentoo is sometimes referred to as a meta-distribution due to the extreme flexibility of Portage, which makes it operating-system-independent. The Gentoo/Alt project was concerned with using Portage to manage other operating systems, such as BSDs, macOS and Solaris. The most notable of these implementations is the Gentoo/FreeBSD project.

In Unix computing, Ion is a tiling and tabbing window manager for the X Window System. It is designed such that it is possible to manage windows using only a keyboard, without needing a mouse. It is the successor of PWM and is written by the same author, Tuomo Valkonen. Since the first release of Ion in the summer 2000, similar alternative window management ideas have begun to show in other new window managers: Larswm, ratpoison, StumpWM, wmii, xmonad and dwm.

pkgsrc Package manager for Unix-like operating systems

pkgsrc is a package management system for Unix-like operating systems. It was forked from the FreeBSD ports collection in 1997 as the primary package management system for NetBSD. Since then it has evolved independently; in 1999, support for Solaris was added, followed by support for other operating systems.

phpLDAPadmin is a web app for administering Lightweight Directory Access Protocol (LDAP) servers. It's written in the PHP programming language, and is licensed under the GNU General Public License. The application is available in 14 languages and supports UTF-8 encoded directory strings.

Technical variations of Linux distributions include support for different hardware devices and systems or software package configurations. Organizational differences may be motivated by historical reasons. Other criteria include security, including how quickly security upgrades are available; ease of package management; and number of packages available.

Nexenta OS, officially known as the Nexenta Core Platform, is a discontinued computer operating system based on OpenSolaris and Ubuntu that runs on IA-32- and x86-64-based systems.

Ports collections are the sets of makefiles and patches provided by the BSD-based operating systems, FreeBSD, NetBSD, and OpenBSD, as a simple method of installing software or creating binary packages. They are usually the base of a package management system, with ports handling package creation and additional tools managing package removal, upgrade, and other tasks. In addition to the BSDs, a few Linux distributions have implemented similar infrastructure, including Gentoo's Portage, Arch's Arch Build System (ABS), CRUX's Ports and Void Linux's Templates.

GNU variants are operating systems based upon the GNU operating system. According to the GNU project and others, these also include most operating systems using the Linux kernel and a few others using BSD-based kernels.
