Can I unpopulate a Git submodule?

Question

Once I run

git update submodule

can I do anything to make it go back to the way it was before init and update?

Answer 1

Try (with git1.8.3, April 22d 2013) a:

git submodule deinit

(See "How do I remove a Git submodule?")

This removes the whole submodule. section from .git/config either for the given submodule(s)

You might have to delete the working tree for that submodule though.
