The location of the ‘`/boot/grub`’ directory as an absolute file name (see How to specify files). This is normally set by GRUB at startup based on information provided by `grub-install`. GRUB modules are dynamically loaded from this directory, so it must be set correctly in order for many parts of GRUB to work.
