Nowadays, in the time of Predictable Network Interface Names, the network interface names 'ethX' are not used that often any more. Depending on the virtualization layer and the guest OS names like 'ens3', 'enp1s0' or 'enp0s31f6' are used. This patch enables the user to set DIB_NETWORK_INTERFACE_NAMES to a list of network interfaces which are brought up using DHCP during (first) boot.
