another feature i've seen for the very first time ... working with kubernetes so i checked it out of github, and part of the instructions for that is to make sure you don't accidentally try to push back to the github remote, so the directions suggest: $ git remote add upstream https://github.com/kubernetes/kubernetes.git $ git remote set-url --push upstream no_push fair enough, i just assumed the word "no_push" was some magical keyword in that context, but as i read it, all you need to do is put *some* invalid URL value there, is that correct? and is that the accepted way to do that? what about just deleting that line from .git/config? is that valid, or is there a different recommendation for doing that? thanks. rday
