+Subject: Make grub-install check for errors from efibootmgr
+
+Code is currently ignoring errors from efibootmgr, giving users
+clearly bogus output like:
+
+ Setting up grub-efi-amd64 (2.02~beta3-4) ...
+ Installing for x86_64-efi platform.
+ Could not delete variable: No space left on device
+ Could not prepare Boot variable: No space left on device
+ Installation finished. No error reported.
+
+and then potentially unbootable systems. If efibootmgr fails, grub-install
+should know that and report it!
+
+We've been using similar patch in Debian now for some time, with no ill effects.
