Presently it is only possible to match on Facts or internal Foreman information when creating a Smart Variable inside a class. I don;t really see any difference between a Fact and a Parameter, since one is a piece of information discovered by the host, and one is a piece of information specified by the admin. Both should be able to be acted upon.

Thus, I'd like to be able to match on Parameters, rather than writing clunky Puppet code which deploys the paramter to a file so it can be read as a fact :)
