Comment 5 for bug 1258351

Ideally we'd be able to add extra files into the conf.d directory of an already running instance by simply stack-updating a section like this into the metadata:

    oac:
      - body: "lorem ipsum dolores {{neutron.host}}"
        path: "/etc/maud/conf.d/xyzzy"
        control:

This would be a simple extension to the os-apply-config os-refresh-config script.
