Comment # 7 on bug 937067 from Arvin Schnell

With libstorage 2.25.30 the user can now override the EFI detection of
libstorage with efi=0/1.

But a test on Tumbleweed shows that the bootloader does not work: In
YaST I get a red error message: "Unsupported combination of hardware
platform x86_64 and bootloader grub2-efi.

Josef, please comment on the bootloader side.
