Different enough to warrant it's own bug, cloning...

This would definitely be good to fix in bullseye, but this is quite late
in the release cycle.

Will need to test failure and success cases with and without EFI as well
as boot.scr and extlinux.conf to make sure this doesn't cause
regressions in other boot paths...

An ugly workaround in the meantime would be to add a no-op boot.scr on
the media (e.g. mmc0) and then fall back to the other boot methods.
