Usage: grub-mkrescue [OPTION] output_image
Make GRUB rescue image.
-h, --help print this message and exit
-v, --version print the version information and exit
--modules=MODULES pre-load specified modules MODULES
--overlay=DIR overlay directory DIR in the memdisk image
(may be specified multiple times)
--pkglibdir=DIR use images from directory DIR instead of ${pkglibdir}
--grub-mkimage=FILE use FILE as grub-mkimage
grub-mkimage generates a bootable rescue image of the specified type.
