None that I know of mainly because we have not yet reached the goal we
are aiming at. Maybe we should write something, A few points from
$dayjob that come to my mind:

  * A submodule commit is only allowed to be merged into master in a
    superproject commit if it is merged into master (or a stable branch)
    in the submodule. That way you ensure that any submodules commits
    that are tracked in a superproject are contained in each other and
    can be cleanly merged. (no rewinds, one commit contains the other)

  * Submodule should be selfcontained (i.e. if its a library have tests
    that use the code you implement). That way changes in the submodule
    can be made independent from the superproject

  * If a submodule needs another submodule have them side by side
    instead of one inside another. See the next point for explanation.

  * Only one depth of recursion for submodules. Even though intuition
    tell you that if some submodule needs another it should contain the
    other its IMO not wise to do so. There will be times when some other
    submodule needs the same submodule that is contained in the other
    and then you end up with two copies of the same code. My suggestion:
    Let the superproject bundle all the dependencies between modules.

  * Submodules are a good solution for shared code where the dependency
    goes superproject needs submodule. If you divide code into
    submodules because of access control and the dependency is actually
    that the submodule needs the superproject it works but is less than

Thats what I can quickly suggest and probably far from complete.
