That seems like a problem, unless I"m misunderstanding something.  If we do
that in the main package, then anyone running a pc-1.0 system under the
qemu package won't be able to migrate.  Wouldn't it be better to have
pc-1.0 alias by default point to the pc-1.0-qemu machine type?

Hm.  No idea offhand how I'd do that, but it sounds worth looking into.
