title: Git: "please tell me who you are" error
body: <p>I have app servers that I bootstrap together using Chef + some ad-hoc bash scripts. The problem is, when I want to run an update on one of these app servers, I get:</p>
  
  <pre><code>19:00:28: *** Please tell me who you are.
  
  Run
  
    git config --global user.email "you@example.com"
    git config --global user.name "Your Name"
  </code></pre>
  
  <p>Do I really need to set this for doing a simple <code>git pull origin master</code> every time I update an app server? Is there anyway to override this behavior so it doesn't error out when name and email are not set?</p>
