Joshua, because of COOK-1653, I don't think he could do that unless he 
actually provided a mirrorlist.

When that LWRP first got released, mirrorlist was a boolean.  So if 
mirrorlist was true, it sets the url as the mirrorlist in the template.  
If mirrorlist was false, it places the url as baseurl, in the template.  
Because EPEL uses a mirrorlist, if you passed in a baseurl of a local 
mirror, it would probably not work with the mirrorlist keyword in the 
rendered template.  We don't really have the logic to handle that in the 
recipe, it passes in mirrorlist blindly without any sanity checking here.

The recipe as it stands.

yum_repository "epel" do
  description "Extra Packages for Enterprise Linux"
  key node['yum']['epel']['key']
  mirrorlist node['yum']['epel']['url']
  action platform?('amazon') ? [:add, :update] : :add
end

If we were to revert to using a pure boolean (not a boolean -OR- a 
string for mirrorlist), one could set the mirrorlist to false, set the 
url to the baseurl of the local mirror, and let the template handle the 
logic.  On the other hand, you could set mirrorlist to true, and the url 
attribute to the EPEL mirrorlist if you wanted to use the default 
behavior.  Again letting the template handle that url/mirrorlist 
switching logic.
