This source can be used to fetch ostree commits. The commits are accessed via their commit is. The only option currently is `url`, given for each commit, that will be used as the location of the remote. A cache repository, that will be created if necessary, acts as an intermediary, so remotes will be added with `name` as the identifier to it and commits are pulled into that. In the output directory another repository will be created as 'repo' and the requested commit pulled into that from the cache repository via a local pull.
