[$] The GhostBSD in the machine
GhostBSD is a desktop-oriented operating system based on FreeBSD and the MATE Desktop Environment. The goal of the project is to lower the barrier to entry of using FreeBSD on a desktop or laptop system, and it largely succeeds at this. While it has a few rough edges that make it hard to recommend for the average desktop user, it is a fine choice for users who want a desktop with FreeBSD underpinnings such as the Z File System (ZFS), and the Ports (source) and Packages (binary) software collections.
