yumrepoinfo.conf adjusted:
https://pagure.io/taskotron/libtaskotron/c/61b1716cf5f9e49faeaa9237436573bdf7ba7394?branch=develop
However, I'm hesitant to push this live due to
https://pagure.io/taskotron/libtaskotron/issue/328
https://github.com/fedora-infra/bodhi/issues/794
We can either make upgradepath (and maybe something else?) crash for all releases, or avoid testing F27 until Bodhi knows about it. I'd probably go with the latter.

We also need to update imagefactory configs, but neither
http://dl.fedoraproject.org/pub/fedora/linux/development/27
nor
https://mirrors.fedoraproject.org/mirrorlist?repo=fedora-27&arch=x86_64
works yet so we need to wait for that.

I pushed a change in upgradepath that could work around this issue. So once the repos and mirrormanager are updated, we can try to deploy this to dev.

I have deployed yumrepoinfo and imagefactory changes. Upgradepath seems to be working fine. F27 minions seem to fail to compose, but we can deal with that separately. Closing.
