This seems to me like a good installer feature - give the user an
option to enter a name for an interface, with the default option
to use the eth* names. To illustrate by example, I imagine an
installer flow that looks like this:
[Do Hardware Discovery]
[Automatically reorder kernel names for reasonable defaults;
eth0-eth{n-1} map to n onboard nics]
Sample user interface for network configuration:
------------Choose an interface to configure --------------
| Multiple unconfigured interfaces detected. |
| Select an interface to configure by: |
| 1. Kernel name (eth0, eth1, etc) |
| 2. Mac Address |
| 3. Chassis name |
| 4. PCI Slot |
-----------------------------------------------------------
----Choose an interface to configure (by chassis name)-----
| 1. LOM0 |
| 2. LOM1 |
| 3. Undefined |
| 4. Undefined |
-----------------------------------------------------------
----------------Name interface - (chassis name LOM0)-------
| Name to use for this interface [eth0]: __mynet0_ |
-----------------------------------------------------------
-----------------------------------------------------------
| Configure interface - mynet0 |
| 1. DHCP |
| 2. Static |
| ... |
-----------------------------------------------------------
