So how about adding "-k" to

  http://git.savannah.gnu.org/cgit/grub.git/tree/util/grub-mkrescue.c#n812

  rv = grub_util_exec ((const char * []) { "mformat", "-C", "-f", "2880", "-L", "16", "-i",
        efiimgfat, "::", NULL });

and waiting for some EFI that will take offense ?
(Then at least we know why we need more than what -k gives.)

For now we have one old Macbook firmware which likes it.


Have a nice day :)
