Well, you can rename them to whatever you like, so anything other than the stuff in very early boot that renames them (pretty much, anything after udev runs) that relies on specific names is broken already.

(FWIW, I've been running Fedora systems with network interfaces udev-renamed to descriptive names for many years with no problems at all.)

@nix

Thank you for the clarification. That makes perfectly good sense. I guess I still feel that this could have been done more cleanly. Relaying on the network device name for bus location seems like a conflict of interests. I just hope people don't start depending on the names not changing.

Agreed. It feels like a horrible and gratuitously nonportable layering violation to use PCI bus IDs for anything related to networking... I suppose in this case they *want* ambiguity, so that they'll get the same name on *every* machine with a card plugged into the same slot. Seems really risky to me, but, hell, I'm not the target market.
