Debian GNU/kFreeBSD is a port of the Debian operating system that consists of the GNU userland, GNU C library, Debian package management (dpkg, apt etc.) and system tools, on top of the FreeBSD kernel.

Although some bugs still exist, Debian GNU/kFreeBSD is a very complete and usable system. Supported desktop environments include GNOME, KDE and Xfce, among others. The FreeBSD 6.x kernel is currently in use as the default system and installer kernel. Packages of the 7.x series kernel are also available.

Debian GNU/kFreeBSD is currently available for the i386 and amd64 architectures and generally supports the same hardware that a normal FreeBSD release would.
