Hello,

To reconfigure my system on UEFI, I had to apply this patch:

Before that ‘grub-install’ would fail because ‘efi-dir’ would actually
be “/dev/sda”, which is what I have in the ‘device’ field of
‘grub-configuration’.

Removing the “--efi-directory” solves the problem because ‘grub-install’
automatically determines that the EFI directory is mounted at /boot/efi.

I think 2941b347b664a3d3114de0ac95e28db78db66144 is bogus because it
assumes that the second argument of the gexp’d lambda is ‘efi-dir’,
where in fact it is the ‘device’ field of the bootloader config.

So what is the preferred fix?  Simply remove “--efi-directory” like I
did above, and rename ‘efi-dir’ to ‘device’ to avoid the ambiguity?
Thoughts?
