> * commits the resulting submodule pointer "A" in the branch to the parent repo
> * then do further rebasing in the submodule, e.g to move up on top of the "bar" branch
> * commits that pointer "B" to the parent repo
> * forgets to squash the history in the parent repo
> * pushes the updated submodule "foo" branch to the online repo. (NOTE: "B" is pushed, not "A")

> When the parent repo is pulled by another developer, or an autobuild system, the fetch operation fails with the message "Server does not allow request for unadvertised object". A second fetch will complete successfully.
