| | 53 | [http://hurd.gnu.org GNU Hurd] reimplements Unix in a multi-server environment on top of the Mach microkernel. The Hurd runs on single-processor ia32 systems. Port to amd64 is underway. Some of the Hurd's components, such as parts of the ```etx2fs``` file server and the ```pfinet``` networking server are in fact borrowed from ancient versions of Linux, while some other components are original. NIC and disk drivers are also taken from Linux, but run as part of Mach in kernel mode. There are experimental versions of the Hurd with support for running Linux 2.6.x networking and disk drivers in user mode (via DDE). |
