Debian GNU/Hurd is a Debian GNU system that replaces the Linux monolithic kernel with the GNU Hurd — a set of servers running on top of the GNU Mach microkernel. The Hurd is still unfinished, and is unsuitable for day-to-day use, but work is continuing. The Hurd is currently only being developed for the i386 architecture, although ports to other architectures will be made once the system becomes more stable. For more information, see the Debian GNU/Hurd ports page and the debian-hurd@lists.debian.org mailing list.
