public class OpenBsdOperatingSystem
extends AbstractOperatingSystem

OpenBsd is a free and open-source Unix-like operating system descended from the Berkeley Software Distribution (BSD), which was based on Research Unix. The first version of OpenBsd was released in 1993. In 2005, OpenBsd was the most popular open-source BSD operating system, accounting for more than three-quarters of all installed simply, permissively licensed BSD systems.
