git submodule update just does "git fetch" and hopes that the required
commit appears. In practice this means that you (may) need to invent a
tag or a branch for all the submodules, otherwise they are not
fetchable.

This bit us pretty hard when we tried to use submodules earlier, so we
gave up. Maybe some day...
