I think that this name does not end up in a FAT filesystem but rather
in HFS+, where it gets blessed. (It also ends up in ISO 9660.)

707:       core_services = grub_util_path_concat (4, iso9660_dir, "System", 
"Library", "CoreServices");

753:              xorriso_push ("-hfs-bless-by");
754:              xorriso_push ("i");
755:              xorriso_push ("/System/Library/CoreServices/boot.efi");

This xorrisofs option would not reach a file in the EFI boot image.


Have a nice day :)
