Comment 4 for bug 147257

Maybe I need to clarify that I did a fresh install. Currently I have no files named /etc/iftab or /etc/udev/rules.d/70-persistent-net.rules.

The contents of /etc/network/interfaces:
==============
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth1
iface eth1 inet dhcp
==============

I just changed the primary network interface to refer to eth1 instead of eth0. I think this should be classified as a workaround, since there was a mismatch between the installer-generated interfaces file and the actual ethn interface number, but it was fixable in this fashion.
