From http://www.freedesktop.org/wiki/Software/systemd/PredictableNetworkInterfaceNames/ You disable the assignment of fixed names, so that the unpredictable kernel names are used again. For this, simply mask udev's rule file for the default policy: ln -s /dev/null /etc/udev/rules.d/80-net-setup-link.rules (since v209: this file was called 80-net-name-slot.rules in release v197 through v208)
