e1000 defaulting to eth1

[Paul]

Hardware: Dell PowerEdge 1800

The onboard e1000 NIC defaults to eth1 using Ubuntu 7.10 beta. It's the only network card in the machine and an ifconfig -a lists lo and eth1.

[ 210.511654] e1000: eth0: e1000_probe: Intel(R) PRO/1000 Network Connection

Fixed via:
- sudo vi /etc/udev/rules.d/70-persistent-net.rules
- look for the line listing the network card (the last in mine) and change NAME="eth1" to NAME="eth0" and save the file
- reboot and the nic will be eth0 and dhcp/etc works again.
