Re: [atomic-devel] Storage for system containers

The only issue I have with using the same location is that when troubleshooting, it's fairly common to wipe the storage pool. I think we'd want users to rm -rf /var/lib/docker without worrying about removing system containers.

Is this still an issue after the current partition scheme moves to OverlayFS?

In Fedora Atomic Host if we use system containers as advertised
we end up using `atomic pull --storage ostree` which by default
throws images into /var/lib/containers/atomic/. This is on the
root filesystem which may be undesirable.

Since in Fedora 26 the new version of container-storage-setup allows
us greater control over a "CONTAINER_ROOT" should we consider trying
to make sure both ostree storage and docker storage get placed under
that CONTAINER_ROOT?

The current default [1] is to just mount the CONTAINER_ROOT on
/var/lib/docker.
