    rename eth1 to eth0 (replaced NIC after install)

    What is the mechanism for permanently renaming an interface in Ubuntu 8.10 Intrepid?

    I had a dodgy 8139too (module) based NIC installed at startup. I switched that out for a unit that (apparently) uses 8139cp. At any rate the point is that the new NIC is eth1, and I'd like to switch it permanently back to eth0 to be consistent with the other Ubuntu systems I manage.
    Code:
    /etc$ sudo grep -R eth1 *
    modprobe.d/blacklist:blacklist eth1394
    network/interfaces:auto eth1
    network/interfaces:iface eth1 inet static
    udev/rules.d/70-persistent-net.rules:
    SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="(snip)", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"
    Do I only need to change the 70-persistent-net.rules and network/interfaces, then reboot?

    Match the MAC Address to the device name is what they mean.

    Update for those who search.
    on 12.04 server & 10.04 desktop (and probably others) you want to look in /etc/udev/rules.d/
