boot.loader.grub.extraGrubInstallArgs

Additional arguments passed to grub-install.

A use case for this is to build specific GRUB2 modules directly into the GRUB2 kernel image, so that they are available and activated even in the grub rescue shell.

They are also necessary when the BIOS/UEFI is bugged and cannot correctly read large disks (e.g. above 2 TB), so GRUB2's own nativedisk and related modules can be used to use its own disk drivers. The example shows one such case. This is also useful for booting from USB. See the GRUB source code for which disk modules are available.

The list elements are passed directly as argv arguments to the grub-install program, in order.
