Hurd
<operating system> The
GNU project's replacement for the
Unix kernel.
The Hurd is a collection of
servers that run on the
Mach microkernel to implement file systems, network protocols, file access control, and other features that are implemented by the Unix kernel or similar kernels such as
Linux.
The GNU C Library provides the
Unix system call interface, and calls the Hurd for services it can't provide itself.
The Hurd aims to establish a framework for shared development and maintenance, allowing a broad range of users to share projects without knowing much about the internal workings of the system - projects that might never have been attempted without freely available source, a well-designed interface, and a multi-server-based design.
Currently there are free ports of the
Mach kernel to the
Intel 80386 IBM PC, the
DEC PMAX {workstation}, the Luna 88k, with more in progress, including the Amiga and
DEC Alpha-3000 machines.
According to Thomas Bushnell, BSG, the primary architect of the Hurd: 'Hurd' stands for 'Hird of Unix-Replacing Daemons' and 'Hird' stands for 'Hurd of Interfaces Representing Depth'. Possibly the first software to be named by a pair of mutually recursive acronyms.
