We regressed on [1] when moving towards persistent NIC naming in [2]. It's cleaner to have the config for this here anyway. This tells NetworkManager to default to using the MAC address as the client ID during DHCP requests to ensure we get the same IP address again during network setup in the real root. See [3] for more background on this. [1] coreos/fedora-coreos-tracker#156 [2] coreos/coreos-assembler#442 [3] coreos/coreos-assembler#367
