DragonFly BSD
Link
Excerpt
DragonFly belongs to the same class of [operating systems](…/operating systems/) as other BSD-derived systems and Linux. It is based on the same UNIX ideals and APIs and shares ancestor code with other BSD [operating systems](…/operating systems/). DragonFly provides an opportunity for the BSD base to grow in an entirely different direction from the one taken in the FreeBSD, NetBSD, and OpenBSD series.
