Subject: [PATCH] provide option in config to enable linuxefi
|

As linuxefi module requires kernel 3.6 or later which supports EFI
|
|
|
|
|
handover protocol, it may not be able to load kernels without that
|
|
|
|
|
supports in place.
|
|
|
|
|
|
|
|
|
|
In case that things would break, and the linuxefi is really too young to
|
|
|
|
|
take over the position of "linux" kernel loader module, we introduce a
|
|
|
|
|
option GRUB_USE_LINUXEFI in the config and only explicit set it to true
|
|
|
|
|
will enable it. Example usage is
|
|
|
|
|
|
|
|
|
|
GRUB_USE_LINUXEFI=true grub2-mkconfig -o /boot/efi/EFI/opensuse/grub.cfg
|
|
|
|
|
|
|
|
|
|
This will output a grub.cfg which uses linuxefi in replace of linux and
|
|
|
|
|
enable verification of kernel signature if in secureboot enabled and
|
|
|
|
|
has shim exported protocols available.
