On one of my nodes, Puppet does not pick up the networking.interfaces fact. The fact is visible when querying Facter directly for the top-level fact (e.g. facter networking) but does not show up through Puppet (e.g. puppet facts show networking) or when querying the sub-fact value (e.g. facter networking.interfaces).
