Re: GRUB2: Possible to change keyboard layout in stage 1.5?

[Pascal Hambourg]

Note : "stages" are GRUB legact concepts which do not exist any more in 
GRUB. What you are referring to is the core image.

Yes, with the --modules= option passed to grub-install.

I am not sure that grub-install uses that variable.

This has not effect on the core image, only on grub.cfg generated by 
update-grub.

If you want the core image to use an embedded config file, I you can 
generate the core image with grub-mkimage with the option --config=. 
IIUC, the embedded config file must end with

insmod normal
normal

which is what the core image normally does without an embedded config file.

To include other files (such as si.gkb) in the core image you can embed 
a memdisk image with --memdisk=. The device name is (memdisk).
