title: Debian - sources.list for "testing" - what to change?
body: <p>I want to use testing-distribution (currently thats "wheezy" instead of the stable "squeeze") of Debian, and am about to adjust my /etc/apt/sources.list file.</p>
  
  <p>I know that I have to replace squeeze by wheezy for the main entry. </p>
  
  <p>But do I have to do this for security (squeeze/updates) and updates (squeeze-updates) too?</p>
