title: Install several packages in one call to underlying package manager with Chef?
body: <p>Package managers are so slow on the uptake ;) I'm using Yum on CentOS and installing each package takes much time.</p>
  
  <p>Is there a way to install several packages in a one call to the underlying package manager in Chef? I can just execute yum or RPM from the recipe, but this is not elegant and not portable also.</p>
