Ah, "minor" forgotten detail. Just fill the blanks, with
%{_libdir}/*.so.* and %{_libdir}/*.so.

That's what I wrote "at least for i386/x86_64", every current or
future multiarch system will define its primary and secondary archs
differently.

He doesn't *have* to, but he may *want* to.

The difference is that in the current model we have to choose for the
user, and we seem to make the wrong choices, since every FC release
has been redifining what we allow the user to do. So just let them
have the full thing, so they can deploy whatever multi-scenario they
need and we don't have to care about stuff beginning with multi
anymore.

So you never wanted to check how mplayer on i386/x86_64 behave? FWIW
most users install mplayer.x86_64 and when they hit on something that
doesn't work they are desperate about getting the i386 version. Same
for firefox until now.
