＠ How to halt:

     reboot [flags]
            Reboot, using the optionally supplied boot flags, which is a bit-
            mask supporting the same values as for reboot(2).  Some of the
            more useful flags:

            Value    Name            Description
            0x1      RB_ASKNAME      Ask for file name to reboot from
            0x2      RB_SINGLE       Reboot to single user mode
            0x4      RB_NOSYNC       Don't sync before reboot
            0x8      RB_HALT         Halt instead of reboot
            0x40     RB_KDB          Boot into kernel debugger
            0x100    RB_DUMP         Dump unconditionally before reboot
            0x808    RB_POWERDOWN    Power off (or at least halt)

            Note: Limitations of the command line interface preclude specifi-
            cation of a boot string.
