Use the source ref that matches `master` (e.g. `refs/heads/master`)
to update the ref that matches `satellite/master` (most probably

+This is to emulate `git fetch` run on the `mothership` using `git

+only make connection in one way (i.e. satellite can ssh into
+mothership but mothership cannot initiate connection to satellite
+because the latter is behind a firewall or does not run sshd).

+After running this `git push` on the `satellite` machine, you would

+made on `satellite`.
