NetworkManager calls new network card eth2, not eth1

[Nick Urbanik]

Dear Folks,

After replacing the second network card with a new one, NetworkManager
refuses to listen to the startup scripts (shown below).  It always
calls the new interface eth2, not eth1.

1. Where does NetworkManager hold its definitions of network
    interfaces?

2. Does the UUID have something to do with my problem?  How does this
    get generated?  Should I uses uuidgen to make a new one for eth1?

I would really like to understand NetworkManager, but it makes things
more complicated for me on this machine.

$ ls /etc/sysconfig/network-scripts/ifcfg-*
/etc/sysconfig/network-scripts/ifcfg-eth0
/etc/sysconfig/network-scripts/ifcfg-eth1
/etc/sysconfig/network-scripts/ifcfg-lo

$ cat /etc/sysconfig/network-scripts/ifcfg-eth0

I am now using Fedora 12; the same problem existed with Fedore 11.

I fixed things after boot with:
/sbin/ip link set down dev eth2
/sbin/ip link set name eth1 dev eth2
/sbin/ifup eth1

So now (until next reboot) I have:

$ ip link ls dev eth1
3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UNKNOWN qlen 1000
     link/ether 00:b0:c4:02:d5:fd brd ff:ff:ff:ff:ff:ff
