Just want to report that I have a motherboard (A785GMH/128M) that will
fail to boot the moment a RAID disk is present.
Grub will just not see any devices. It will fail with a message that
(hd0) could not be found.
"ls" then yields nothing, an empty line as output.
This is also true when boot

Grub installs efi kernels into grub.cfg with grub-mkconfig on non-uefi
systems.
The Ubuntu /etc/grub.d/10_linux checks for the existence of
/sys/firmware/efi but Git grub does not.
I don't know how to fix it other than by copying the file over.

If under "install" you mean "adds menu entry for" - please explain what
"efi kernel" is, why grub should not add menu entry for it and how to
detect it.
Oh, so this is an Ubuntu specific. My apologies.

Not any type of filesystem, because /boot/grub is encrypted so
