title: Uninstalling a package using Chef
body: <p>I have been using Chef to manage our servers.</p>
  
  <p>My roles/app.rb looks like this:</p>
  
  <pre><code>name "app"
  
  description "App server"
  
  run_list [
      "recipe[apt]",
      ...,
      ...,
      "recipe[nginx]"
      ...,
      ...,
  ]
  </code></pre>
  
  <p>Now I would like to remove the nginx package from the machine.
  If I remove the nginx recipie in run_list, will it remove nginx from the nodes? If not please advise me what is the best strategy to have change-management on nodes.</p>
