You also have to make sure that all your submodule commits that _ever_ have been part of your submodule have be stay in your repository forever. Consider that your submodule switches to an other branch and some old commits are not referenced by the current version any more. These old commits still have to survive a git-prune, if they have been part of some old supermodule version. So you really have to connect both object databases and it's not enough to just store the commit sha1 without actually parsing it by the GIT core. -- Martin Waitz
