        !            13: .I Reboot
        !            14: reboots the system, and is invoked automatically
        !            15: in the event of unrecoverable system failures.
        !            16: .I Howto
        !            17: is a mask of options passed to the bootstrap program.
        !            18: The system call interface permits only RB_HALT or RB_AUTOBOOT
        !            19: to be passed to the reboot program; the other flags
        !            20: are used in scripts stored on the console storage media, or used
        !            21: in manual bootstrap procedures.
        !            22: When none of these options (e.g. RB_AUTOBOOT) is given, the system is rebooted
        !            23: from file \*(lqvmunix\*(rq in the root file system of unit 0
        !            24: of a disk chosen in a processor specific way.
        !            25: An automatic consistency check of the disks is then normally performed.
        !            26: .PP
        !            27: The bits of
        !            28: .I howto
        !            29: are:
        !            30: .TP
        !            31: RB_HALT
        !            32: the processor is simply halted; no reboot takes place.
        !            33: RB_HALT should be used with caution.
        !            34: .TP
        !            35: RB_ASKNAME
        !            36: Interpreted by the bootstrap program itself, causing it to
        !            37: inquire as to what file should be booted.  Normally, the system is
        !            38: booted from the file \*(lqxx(0,0)vmunix\*(rq without asking.
        !            39: .TP
        !            40: RB_SINGLE
        !            41: Normally, the reboot procedure involves an automatic disk consistency
        !            42: check and then multi-user operations.  RB_SINGLE prevents the consistency
        !            43: check, rather simply booting the system with a single-user shell on
        !            44: the console.
        !            45: RB_SINGLE is interpreted by the
        !            46: .IR init (8)
        !            47: program in the newly booted system.
        !            48: This switch is not available from the system call interface.
