I have a list of interfaces and > what they're for." even when they already have udev. I see that as a liability not a feature. Our routers have very clear naming conventions for interfaces and they are exactly how Cisco enumerates them and no other way. It's a firing offense to dick with them and dream up useless "descriptive names". Mind you, these for the most part are big iron with several 1000 interfaces each and 100+ support personnel working on them. But even the on-site routers and firewalls at customer premises have the same rule. I assume we are talking about kit that routes properly (whether a Unix or something else is not relevant) and not some joke system. As for NICs that do not come up at boot time in a consistent order, if any piece of hardware in our DC did that it would be sent right back to the vendor labeled as a piece of shit with a demand for a refund. FFS, if my boss shells out 3 months wages for some iron and it can't even get something that basic correct, I start to wonder what else might be dodgy. There is ZERO excuse for a system that cannot deterministically enumerate it's fixed devices at boot time. -- Alan McKinnnon alan.mckinnon@gmail.com
