dustymabe reported a new issue against the project: `atomic-wg` that you are following: `` The `20170215` qcow/vagrant images we released don't properly detect and use static deltas. I've been told this is because we are leaving the `fedora-atomic/25/x86_64/updates/docker-host` ref on the system as a result of the [trickery](https://pagure.io/fedora-kickstarts/c/3fd7e8b00972e53fbea43c72365a2a64dbd6c453?branch=f25) we perform in the installer. The non-use of static deltas won't be a big issue once [this issue](https://github.com/ostreedev/ostree/pull/710) is fixed upstream, but leaving around the ref is supposedly bad because some files that could get cleaned up won't and will take up space that they shouldn't. We'll just move to a model where we don't leave around the other ref.
