grub-reboot - set the default boot entry for GRUB, for the next boot only

       Set the default boot menu entry for GRUB, for the next boot only.

       -h, --help
              print this message and exit

       -V, --version
              print the version information and exit

       --boot-directory=DIR
              expect GRUB images under the directory DIR/grub instead of the /boot/grub directory

       MENU_ENTRY  is  a  number,  a  menu  item title or a menu item identifier. Please note that menu items in
       submenus or sub-submenus require specifying the submenu components and then the menu item component.  The
       titles  should  be separated using the greater-than character (>) with no extra spaces. Depending on your
       shell some characters including > may need escaping. More information about this is available in the GRUB
       Manual in the section about the 'default' command.

       NOTE: In cases where GRUB cannot write to the environment block, such as when it is stored on  an  MDRAID
       or LVM device, the chosen boot menu entry will remain the default even after reboot.
