The f28 repos we need to tap into are not in the same locations
as for post release (f26/f27) runs. We also don't need to include
the 'updates' repo because there is no updates repo for f28 yet.
This is actually an f28 repo, but I had made a mistake moving things around (I
accidentally moved things out of the os/ directory in the empty-repo, while this was
supposed to have happened in the /pub repo), so let's keep that.
Also, for the compose/[[ release.version_int ]]/latest-Fedora, I think we should just
create a symlink of /28 to /branched perhaps, but that'd be the only part we should
have in this patch.
+ [% if release.version_int >= 28 %]
Let's use an explicit release.version_int == 28, to indicate that this is only the
case for now while we are in branched state.
