To summarize the responses and my actions. |

1. Indeed the system had assigned the new wired ethernet device |
12 |
a new name (eth2, my wireless is eth1, previous wired was eth0). |
13 |
|
14 |
2. /etc/udev/rules.d/persistent-net.rules does tell the story. |
15 |
This file ensures that the same PHYSICAL device keeps the same name. |
16 |
Once you change the hardware, the same "logical device" (in my case |
17 |
wired ethernet) gets a new permanent name. |

3. Some advised blowing away .../persistent-net.rules. |
20 |
I chose to modify it so that the new device is now eth0 and the old |
21 |
device is gone. |
