The script persistent-net-generator.rules generates the
file /etc/udev/rules.d/z25_persistent-net.rules. There you will see how
udev maps a hardware address to a logical interface name such as eth0.
Therefore you will need to swap around the names in that file just as
you have done in /etc/network/interfaces.
