def find_facts
  # This works because puppet agent configures Facts to use 'facter' for
  # finding facts and the 'rest' terminus for caching them.  Thus, we'll
  # compile them and then "cache" them on the server.
  begin
    reload_facter
    facts = Puppet::Node::Facts.find(Puppet[:node_name_value])
    unless Puppet[:node_name_fact].empty?

    raise
  rescue Exception => detail
    puts detail.backtrace if Puppet[:trace]
    raise Puppet::Error, "Could not retrieve local facts: #{detail}"
  end
end

#reload_facter ⇒ Object

Clear out all of the loaded facts and reload them from disk. NOTE: This is clumsy and shouldn’t be required for later (1.5.x) versions of Facter.
