commit 5ee314b6c1ffd8b090ca6771f0896e080f7000ef

    startup: bind the startup server to /servers/startup
    
    Previously, the Hurd (ab)used the fact that the startup server speaks
    all protocols on its message port.  Any server that wished to register
    for shutdown notifications would use proc_getmsgport to get a port to
    the startup server.
    
    This hardcodes the PID of /hurd/startup, and does not allow one to
    point a server to ones own startup server (e.g. using remap).
    
    Bind the startup server to /servers/startup instead.  Use this to
    contact the startup server.
    
    * exec/main.c (S_exec_init): Use /servers/startup.  Fall back to the
    old method so that the system still boots when the node
    /servers/startup is missing.
    * hurd/paths.h (_SERVERS_STARTUP): New macro.
    * libdiskfs/boot-start.c (diskfs_S_fsys_init): Use /servers/startup.
    * libdiskfs/init-startup.c (_diskfs_init_completed): Likewise.
    * pfinet/main.c (arrange_shutdown_notification): Likewise.
    * startup/Makefile (OBJS): Add fsysServer.o.
    * startup/startup.c (demuxer): Handle the fsys protocol.
    (main): Bind to /servers/startup.
    (S_fsys_getroot): Implement fsys_getroot.  Stub out the rest.

    startup: fix the declaration of the *_server functions
    
    * startup/startup.c (demuxer): Fix the declaration of the server functions.

    startup: be more specific in the shutdown message
    
    Use the BOOT macro to print either halt or reboot instead of the
    generic shutdown in the event of an system shutdown.
    
    * startup/startup.c (reboot_system): Use more specific message.

    startup: do not pass signals on to the child
    
    Formerly /hurd/startup would forward all signals to the child it
    started (e.g. /libexec/runsystem).
    
    The motivation for doing so is not revealed in the comments, nor it is
    mentioned in the history of the version control system.
    
    This patch removes the forwarding of signals to the child.
    
    * startup/startup.c (process_signal): Do not pass signals on to the child.
    * startup/stubs.c: Remove file.
    * startup/Makefile: Remove stubs.c.

    init: add a minimalist init program
    
    This patch adds a minimalist init program.  It is somewhat lacking in
    features, but is able to bring up a Hurd system with the runsystem and
    rc scripts.  In fact, it roughly does what the former /hurd/init did,
    modulo all the very early bootstrapping stuff and the startup
    protocol.  It is started when all the essential servers are up and
    running, so it can make use of most of the POSIX goodies, making its
    implementation much simpler.
    
    * Makefile (prog-subdirs): Add init.
    * daemons/runsystem.sh: Generalize runsystem so that it can start any
    init as specified on the kernel command line.  By default, it starts
    /hurd/init.
    * daemons/runsystem.hurd: This is a verbatim copy of runsystem.sh.  It
    is started by /hurd/init.
    * daemons/rc.sh: Do not start /hurd/mach-defpager as it is already
    started in runsystem.sh.
    * daemons/Makefile (SRCS): Add runsystem.hurd.
    * init/Makefile: New file.
    * init/init.c: Likewise.

    startup: rename /hurd/init to /hurd/startup
    
    This patch series splits /hurd/init into two programs.  As a first
    step, this patch renames /hurd/init to /hurd/startup.  It is called
    startup because it speaks the startup protocol.
    
    * startup: Rename init to startup.  Adjust accordingly.
    * Makefile (prog-subdirs): Likewise.
    * doc/hurd.texi (Server Bootstrap): Likewise.
    * hurd/paths.h (_HURD_STARTUP): Likewise.
    * libdiskfs/boot-start.c (diskfs_boot_init_program): Likewise.
    * libdiskfs/opts-std-startup.c (startup_options): Likewise.

    procfs: do not hard-code the default argument values
    
    * procfs/main.c (common_options): If possible, do not hard-code the
    default values.

    Add proc_set_init_task, make runsystem pid 1
    
    * hurd/process.defs (proc_set_init_task): New procedure.
    * hurd/process_reply.defs (proc_set_init_task): Likewise.
    * hurd/process_request.defs (proc_set_init_task): Likewise.
    * include/pids.h: Add HURD_PID_INIT as 1, adjust others accordingly.
    * init/init.c (start_child): Register the child task.
    * proc/proc.h (init_proc): New variable.
    (create_startup_proc): Rename to create_init_proc.
    * proc/main.c (main): Create placeholder proc object for pid 1.
    * proc/mgt.c: Use init_proc instead of startup_proc, as the former is
    the new root of the process tree.
    (create_startup_proc): Rename to create_init_proc.
    (S_proc_set_init_task): New function.
    * doc/hurd.texi (Server Bootstrap): Update accordingly.
    * procfs/main.c: Do not hard-code kernel pid, use pids.h instead.
