title: Parameterize chef recipe
body: <p>I have a recipe in chef, which I want to use multiple times (in multiple roles), only with a few parameters different. I want to be able to use multiple such roles on the same node. </p>
  
  <p>How can I "parameterize" the recipe? I can't use attributes, because those are on node, so one role would override another's attributes.</p>
