This seems a little dangerous to me.  Maybe just bail out with an error here telling them to delete the directory and rebuild if they want to switch repos?

Alternatively, switch the directory name to correspond with which repo is being used so that it would just switch directories and download the other repo?

I know that some people actually develop in their payloads directories, and I don't want people to lose their data because of a slip up.

That could happen in a follow-on patch if you want.
