Git disable pushing from local repository

Question

I have a repository with some core code in it, and for each client I wish to clone it so I can do git pull everytime a client wants to upgrade to the newest functionality.

In the interest of not screwing things up and making changes that only one company sees, is there a way to only allow fetches on a local repository basis? I still want to be able to push changes to the core repo from my dev environment, but don't want production machines to be able to push.

Specify a non-existing pushurl in the remote section of the clone-source repository (called origin) in the file .git/config. Example:

[remote "origin"]
        fetch = +refs/heads/*:refs/remotes/origin/*
        url = <url>
        pushurl = www.non-existing-url.com

Or if you don't like editing the config file of the repository you can type:

$ git config remote.origin.pushurl www.non-existing.com

When pushing you'll get an error message like:

$ git push
fatal: 'www.non-existing-url.com' does not appear to be a git repository
fatal: The remote end hung up unexpectedly

Of course you'll need to edit the config file of each cloned repository.
