title: Are Hiera settings inherited when including a class?
body: <p>I have Puppet class Foo with an associated Foo.yaml file containing Hiera settings. I need to create a descendant class (Bar) that includes all settings and code from Foo plus some additional Hiera settings.</p>
  
  <p>Is in enough to use "include Foo" in the Bar class definition and create Bar.yaml with extra settings? Or should I additionally copy Foo.yaml to Bar.yaml and add new settings to Bar.yaml? The former approach is preferable but I'm not sure it would work. </p>
