So the value “/sys/firmware/non-efi” might as well be
“/does-not-exist”?

Your patch subject says “Make sure that non-EFI grub doesn't try to use
EFI”, but the problem I had was that GRUB insisted on being passed a
“--target” option.  That was with a GRUB installation on a system in
legacy mode.  Do you mean that this failed because GRUB erroneously
attempted an EFI installation?

I’m thoroughly confused.
