Features of HURD

HURD provides a Unix-like interface to applications that run under it. HURD is structured as a number of communicating user-level processes that run on top of the Mach microkernel. There is almost no machine dependent code in HURD, so all that is necessary is to port the microkernel that supports it to new hardware. In order to do this, it is first necessary to port the GNU C compiler and the binutils — the assembler, the linker and various related utilities. The structure of the HURD is illustrated in figure  and discussed further in Section
