One thing I discovered last night. There's a bug with the new
fedora-release packages and yum/dnf are kind of arbitrarily picking
from fedora-release-[standard|cloud|server|workstation] to install if
you just update. (This is in large part because these are just
placeholder packages and don't have any content in them yet).

To avoid issues going forward, before you do the distro-sync above,
you probably want to 'yum install fedora-release-$something' where
$something is either 'standard' (for non-productized Fedora) or one of
the Products, which your environment will evolve more into the closer
we get to Alpha.

I'll try to work out what we need to do to make that transition
cleaner from F20->F21, but for Rawhide->F21 it's going to be a bit
manual for a while.
