That is my understanding as well. In fact, I don't think the detached-HEAD-vs-branch distinction is important here, you can still rebase your detached HEAD onto the superproject's referenced commit (or origin/$branch with --remote). This will also work for merge, and should work for well-crafted !commands. > And wouldn't it make it unnecessary to have a new "re-attach" option > if such a mode that never have to detach is used? I think so, but we currently don't have a "never detached" route for folks that are cloning submodules via update (instead of via 'submodule add'). Currently, new clone-updates will always leave you with a detached HEAD (unless you have branch-creation in your update !command). My patch aims to close this detached-HEAD gap, for folks we expect will be doing local development, by creating an initial branch at clone-update time.
