#resolve_fact(user_query) ⇒ Object

resolve a fact by name, in a similar way that facter 3 does. search is done in multiple steps, and the next step is executed only if the previous one was not able to resolve the fact

  • load the ‘fact_name.rb` from the configured custom directories

  • load all the core facts, external facts and env facts

  • load all custom facts
