Bug#926178: grub2 efi boot installs grub.cfg file that seems to be ignored (just stays at prompt)

[Norbert Lange]

I got newer versions to work by adding the "--no-uefi-secure-boot" switch,
so apparently uefi-secure-boot is not working for me.

older versions might have defaulted to not using it,
or I did not have the shim packages installed.
