GNU Hurd
Project GNU's replacement for the Unix kernel

The Hurd is the kernel for the GNU system, a replacement and augmentation of standard Unix kernels.

It is a collection of protocols for system interaction (file systems, networks, authentication), and servers implementing them. Subprojects include Mach, the microkernel on which the Hurd is based, which provides a basic inter-process communication mechanism, and MIG, an interface generator for Mach.
