You can have the new commit in a repo that's pulled as a file:// URI , but it entails duplicating all of the content unfortunately. This is somewhat similar to just `rpm -Uvh /path/to/updates*.rpm`, where all of the RPMs are in that set. We've been working on "static deltas" for a while which both increase online update efficiency and make it easier to have an offline "go from A to B" as a set of files. Based on that there is work on a "single file" delta https://github.com/GNOME/ostree/pull/139 which could be enhanced further to be a single file delta.
