Comment 2 for bug 1538220

Also such situation affects us if plugin modify network_metadata and end-user rename node after deploy (LCM).
Such scenario leads a to duplicate node record into the hiera_hash('network_metadata') call:

    network_metadata:
      nodes:
        node-1:
          swift_zone: '1'
          uid: '1'
          fqdn: node-1.test.domain.local
          user_node_name: Untitled (38:fb)
          node_roles:
            - primary-controller
            - plugin-modified-node_role_record
          name: node-1
        renamed_node-1:
          swift_zone: '1'
          uid: '1'
          fqdn: renamed_node-1.test.domain.local
          user_node_name: renamed_node-1 (38:fb)
          node_roles:
            - primary-controller
          name: renamed_node-1
