Topic: GNU Hurd


  
  The GNU Hurd - GNU Project - Free Software Foundation (FSF)
The GNU Hurd is 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).
For all intents and purposes, the Hurd is a modern Unix-like kernel.

  GNU - Wikipedia, the free encyclopedia
The GNU project was announced publicly on September 27, 1983, on the net.unix-wizards [1] and net.usoft newsgroups.
GNU Hurd is the set of programs or services running on top of a microkernel (GNU currently uses the GNU Mach microkernel, but efforts to port Hurd to the L4 microkernel are currently ongoing).
The "GNU" in GNU Hurd indicates that it is a part of the GNU project, while "GNU/Hurd" distinguishes it as one of the two currently available GNU systems--that is, Linux-based GNU systems (or "GNU/Linux") as opposed to Hurd-based GNU systems (or "GNU/Hurd").

 GNU Hurd - Wikipedia, the free encyclopedia
According to Thomas Bushnell, the initial Hurd architect, their early plan was to adapt the BSD 4.4-Lite kernel and, in hindsight, "It is now perfectly obvious to me that this would have succeeded splendidly and the world would be a very different place today" [1].
Because of this slow pace, the GNU userland components came to be used with the Linux kernel and are now commonly associated with "Linux" systems (see also GNU/Linux naming controversy).
GNU Mach is currently used as the microkernel, but efforts are underway to port the Hurd to the more modern L4 microkernel.

 Debian -- Debian GNU/Hurd --- Hurd-CDs
The kernel is GNU Mach not the Hurd.
Both the Hurd and GNU Mach are part of the GNU project while the Linux kernel is an independent project.
As GNU also uses the cross install method, this meant that the scripts to build the GNU installation CDs could be adapted from the Debian GNU/Linux boot and CD scripts so that the GNU rather than the GNU/Linux tarball would be unpacked.

The GNU Hurd's design was motivated by a desire to rectify a number of observed shortcomings in Unix.
To increase extensibility and integration, the Hurd adopts an object-based architecture and defines interfaces, which, in particular those for the composition of and access to name spaces, are virtualizable.

 The GNU Hurd:
The Hurd servers, which run on top of the Mach microkernel, implement the functionality that is usually found in a Unix-like kernel.
For example, fork() is not implemented by any Hurd server, but in the C library directly, which uses Mach and Hurd server primitives to create a mirror image of the current process.
Although the GNU C library provides a POSIX personality on top of the Hurd, and this is the main personality of the Hurd today, there is no reasons why other libraries shouldn't use the Hurd server's functionality to provide a compatibility layer to some other API.

 Just GNU
Given that GNU was around long before Linux and is the source of the majority of the code, etc. I think it would be reasonable to expect major players like IBM, RedHat, Caldera (ha ha ha), etc. to make some note of it in their advertising.
Similarly, BSD with a GNU-software kernel is not GNU, it is BSD with a GNU-software kernel.

 GNU Hurd
Hurd is an acronym for "Hird of Unix-Replacing Daemons".
Hurd would provide the advantages of using Microkernels, such as easy porting to additional architectures, and easy SMP support.
Hurd is just about the only thing still depending on the Mach microkernel, with the result that there are only tiny numbers of people that care about it being ported to newer and better hardware.
