So you're saying that having multiple NICs is a rare thing when you're managing large numbers of systems in data centers?
And if that weren't enough, you readily admit that you're too incompetent to figure out that the mapping from MAC addresses to interface names is stored in /etc/udev/rules.d/70-persistent-net.rules and can be modified there?
You're a crazy person. Get help. Or don't, I don't care.
