Make GRUB rescue image.
-h, --help print this message and exit
-v, --version print the version information and exit
-o, --output=FILE save output in FILE [required]
-d, --directory=DIR use images and modules under DIR [default=${libdir}/grub/@target_cpu@-@platform@]
-O, --format=FORMAT generate an image in format
available formats: $(${bindir}/grub-mkimage --help | \
grep available\ formats | cut -f2 -d:)
-C, --compression=(xz|none|auto) choose the compression to use
--modules=MODULES pre-load specified modules MODULES
--grub-mkimage=FILE use FILE as grub-mkimage
$self generates a standalone image (containing all modules) in the selected format
