When you create a boot variable using efibootmgr, it's better to specify
something that's not the default
binary. It's what Windows, Linux, etc do when they are installed and it
facilitates better multiboot when
the target OSes depend on the first stage efi boot loader (like FreeBSD and
Windows certainly do).
