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 this patch in Debian now for some time, with no ill effects.
