It should not offer the last three commands. On systems which use RAIDframe
they will cause a RAID rebuild when the system startup the next time.
"reboot", "halt" and "poweroff" should only be used under rare circustances.

The appropriate commands are

shutdown        bring system to single user mode
shutdown -r     reboot the system
shutdown -h     halt the system
shutdown -p     poweroff the system, or halt it if poweroff is not
                supported by the hardware

Please read the manual page for shutdown(8) for more information.

        Kind regards
