I had problems finding the answer to this so I am posting it for posterity.

The situation is, you have a git repo with a submodule (similar to an svn external). You want to update that reference to point to a different commit in the external repository. You might think 'git submodule sync' or 'git submodule update' would do that - you'd be wrong.
