 * repository, disambiguating the refs using collection IDs. In order to support
 * peer to peer redistribution of repository metadata, repositories must set a
 * collection ID (ostree_repo_set_collection_id()).
 *
 * Users of OSTree may place arbitrary metadata in commits on this ref, but the
 * keys must be namespaced by product or developer. For example,
 * `exampleos.end-of-life`. The `ostree.` prefix is reserved.
