Due to a new feature (Foreman NIC information represented in the ENC)
clashing with the $::interfaces fact, the $::interfaces fact is
replaced by the structured data from the Foreman ENC.
This could have potential consequences for use of $::interfaces in
your puppet codebase - if you do rely on $::interfaces to manage your
machines, please delay upgrading to 1.7.0 and instead wait for 1.7.1
We hope to have a patch out quickly to address this.
