Comment 1 for bug 1364203

Charms choose their series. Regarddless of the series used by the client or the state-server, each service can be its own series. As there is only a precise version of the charm, that is the version to use.

This problem with the page is that its simple, but ambiguous deployments of charms like "wordpress" will fail if the user has set the default-series in environments.yaml to trusty or utopic.
