title: How to control the version of Chef that Vagrant uses to provision VMs?
body: <p>A current Chef recipe isn't running because of a bug in version 0.10.10. How can I upgrade the version of Chef that Vagrant uses, to 0.10.12?</p>
  
  <p>I don't want to just update it for the current instance of the VM - I keep destroying and rebuilding those. Do I need to change something in the Vagrant base box, or something in my (physical) system's installation?</p>
