Well, the translator concept is one of the tihngs that are underdocumented, but it is at least covered by some stuff. Please try the Debian GNU/Hurd pages at http://www.debian.org/ports/hurd, especially ...hurd/hurd-doc-translator in this case. All below /servers is convention. The Glibc library and Hurd servers are looking in this place for points of communication with the Hurd servers. For example, if a program crashes (segfault), the /servers/crash server will be accessed. Whatever translator is set on this inode will get a chance to handle the crash (for examle by doing a core dump, or putting the process in the background). The /servers/socket/ directory contains, well, sockets :) The translator on /servers/socket/2 implements the pfinet sockets, /servers/socket/1 is for pipes etc. Of course, those translators need to implement a special protocol, which is documented in the *.defs files (those are used by MIG for interprocess communication (IPC) over RPC's). > > > 3) there is no proc > > Right, I just thought df was looking for it :-) Under Linux it does.
