      Given a system administrator responsible for network configuration and the DHCPv4 server changes its option on DNS nameservers,
      When they reapply the NetworkManager device configuration converting dynamic IP to static before DHCPv4 changed DNS nameservers,
      Then the /etc/resolv.conf file should be automatically updated with the new DNS nameservers provided by the DHCPv4 server on the next RENEW process of DHCPv4.

      Definition of Done:

      • The implementation meets the acceptance criteria
      • The unit tests and integration tests are written and passed
      • The code is part of a build attached to an errata
