title: Opscode Chef - way to cleanup /shared/cached-copy
body: <p>We using Opscode Chef in our pipeline and we notice that the deployment (see <a href="http://docs.opscode.com/resource_deploy.html" rel="nofollow">http://docs.opscode.com/resource_deploy.html</a>) creates a complete copy of our sourcecode to /shared/cached-copy</p>
  
  <p>It already has nearly thousand complete versions of it (not just deltas!) in the .git/object folder of it, so filesize growth and growth.</p>
  
  <p>Is there any way to get this cleaned up or even completely prevented? We don't need it at all.</p>
  
  <p>For sure I could write something to delete the directory after each deployment but is there a good way to handle this? Thanks.</p>
