MidnightBSD is a FreeBSD-derived operating system. A critical goal of the project is to create an easy-to-use desktop environment with graphical ports management, and system configuration using GNUstep. The vast majority of the operating system will maintain a BSD license. MidnightBSD was forked from FreeBSD 6.1 beta.
