Grub script should warn about EFI 32 bit system instead of exit silently

[Bruno Duyé]

Hi,

I'm trying to add memtest to my Grub config, and searched a while. Many questions about this "problem" are posted on stack exchange but I didn't quickly found the solution. So I stated to trace and finally found the origin of my problem: I was trying to install FOSS Memtest86 version on a Grub that is launched on EFI mode.
But to find this problem I had to add debug on /etc/grub.d/20_memtest86+ and I here's what really miss there, IMHO:

diff --git debian/grub debian/grub
index 56ca510..11afbe5 100644
--- debian/grub
+++ debian/grub
@@ -15,6 +15,7 @@ fi

 # We need 16-bit boot, which isn't available on EFI.
 if [ -d /sys/firmware/efi ]; then
+ echo "Memtest86+ needs a 16-bit boot, that is not available on EFI, exiting." >&2
   exit 0
 fi

(by the way I don't understood how to submit a PR; why Ubuntu isn't using Gitlab ?!!; so here's the "patch"; super simple so can be put here)

Thanks
