Well, here's the output from "dmesg | grep eth". It shows the r8169
interfaces being given names eth0, eth1 (the ones I want as eth1 and eth2),
then the tg3 interface gets called eth2 (which I want as eth0).
At 6 seconds in, you can see my 70-persistent-net.rules file kicking in and
renaming then to xeth2, xeth1 and xeth0; then finally at 12 seconds, the second
rename in /etc/network/interfaces sets them back to eth0, eth1 and eth2 in the
order I want them.
