I came upon jinit (guess what, a makefile-ish type init) on freshmeat
and I decided to see if it would run for Hurd. Compiling it
was easy except for references to msgsnd(), msgrcv(), msgget() and
msgctl(), and mount-unmount type linux system calls. I noticed that
the msg*() routines are part of the SysV IPC API (as described in
SUSv2) but they were not implemented for Hurd.

If it's worth implementing these routines for Hurd, maybe it's time to
try. If not, I'll try to replace those msg*() references in jinit,
by Mach type message passing for Hurd.
