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

        !            59: .SH "RETURN VALUES"
        !            60: If successful, this call never returns.  Otherwise, a \-1
        !            61: is returned and an error is returned in the global variable

        !            69: .SH BUGS
        !            70: The notion of ``console medium'', among other things,
        !            71: is specific to the VAX.
