Right. We need a standard location (that maybe can be overridden, like you
can with /boot, if you really want), and that's likely the first order of
business. I don't think we should be second guessing, though. And we
shouldn't be touching \efi\boot anything unless specifically instructed to
do so. I'm deeply uncomfortable with guessing whether or not to do
something...
