I think it affects initramfs too.
It only affects boot loaders which don't support version 2.03 of the
boot protocol; unfortunately that includes GRUB last I checked.
We really need a better dialog with the GRUB people, unfortunately at
least I have unsuccessful in starting such a dialog.
GRUB, in particular, needs to report the boot loader ID they're using,
plus support version 2.03 of the protocol.
