Until 2004, NetBSD 1.x releases were made at roughly annual intervals, with minor "patch" releases in between. In 1998, NetBSD 1.3 introduced the pkgsrc packages collection. He later founded a new project, OpenBSD, from a forked version of NetBSD 1.0 near the end of 1995. Also in 1994, for disputed reasons, one of the founders, Theo de Raadt, was removed from the project. The first multi-platform release, NetBSD 1.0, was made in October 1994, and being updated with 4.4BSD-Lite sources, it was free of all legally encumbered 4.3BSD Net/2 code. This was derived from 386BSD 0.1 plus the version 0.2.2 unofficial patchkit, with several programs from the Net/2 release missing from 386BSD re-integrated, and various other improvements. The NetBSD source code repository was established on 21 March 1993 and the first official release, NetBSD 0.8, was made on 19 April 1993. The name "NetBSD" was chosen based on the importance and growth of networks such as the Internet at that time, and the distributed, collaborative nature of its development. They aimed to produce a unified, multi-platform, production-quality, BSD-based operating system. The four founders of the NetBSD project, Chris Demetriou, Theo de Raadt, Adam Glass, and Charles Hannum, felt that a more open development model would benefit the project: one centered on portable, clean, correct code. The NetBSD project began as a result of frustration within the 386BSD developer community with the pace and direction of the operating system's development. NetBSD was originally derived from the 4.3BSD-Reno release of the Berkeley Software Distribution from the Computer Systems Research Group of the University of California, Berkeley, via their Net/2 source code release and the 386BSD project. Its source code is publicly available and permissively licensed. The NetBSD project focuses on code clarity, careful design, and portability across many computer architectures.
It continues to be actively developed and is available for many platforms, including servers, desktops, handheld devices, and embedded systems. It was the first open-source BSD descendant officially released after 386BSD was forked.
NetBSD is a free and open-source Unix operating system based on the Berkeley Software Distribution (BSD). Monolithic with dynamically loadable modules, rump kernel
