Rather, it refers +to the functionality that the kernel provides. It is generally agreed that +this is; a set of interfaces to allow processes to communicate and a way to +talk to the hardware. *Software drivers*, as we like to call them, are then +implemented in user space as servers. The most obvious examples of these are +the TCP/IP stack, the ext2 filesystem and NFS. In the case of the Hurd, users +now have access to functionality that, in a monolithic kernel, they could never +use, but now, because the server runs in user space as the user that started +it, they may, for instance, mount an FTP filesystem in their home directory. + +For more information about the design of the Hurd, read the paper by Thomas +Bushnell, BSG: [Towards a new strategy on OS +design](http://www.gnu.org/software/hurd/hurd-paper.html). |
