Choice is great, surprises not so much. And I find it surprising that NM sometimes runs, sometimes doesn't, depending on seemingly unrelated things.
Those would be bugs, and bugs need fixing. But they can't be fixed if they're not reported.
And I still don't understand how to control what it would do for, say, a dynamically inserted USB device. Is it possible to make it take 'address only' from DCHP in that context?
NetworkManager doesn't work in terms of interfaces, but in terms of connections. I'll have to try it with a USB Wi Fi before I can answer completely, but when you create a connection you get this option, and I would think (and I'm going to try it, since I do have a USB Wi Fi NIC at home, just not sure if it's supported by ELrepo or not) upon insertion a dialog to create a connection will come up, and you select the option from the pulldown in the IPv4 tab. The udev framework allows connections to 'belong' to different NICs, as far as I can tell, and is what makes the connection persistent across reboots in that sense. But I reserve the right to be wrong.
