In general, we want the following in the OS: 1) Device names stay consistent across reboots The current persistent-net.rules udev files, and the current generator files, handle this. 2) Device names stay consistent across reinstalls Currently, anaconda doesn't use any existing information when starting udev (as far as I know), so interfaces can be in random order depending on timing. We don't currently have a mechanism for this. 3) Device names stay (reasonably) consistent across hardware swaps or image distribution to multiple machines (including virt) i.e., if the image is deployed to a new machine, the devices stay the same. We don't currently have a mechanism for this. So, how to handle this? For #2, we obviously can't have a set of rule files that does this; at least not well. (It would need to go back and rename other devices that we've already gotten events for, for example.) We'd need some sort of code that runs after udevsettle that applies an ordering. For #3, the solution proffered is to have the udev writer write two sets of rules: - one that maps based on MAC address - one that maps based on PCI/USB/etc. path The user could then set a configuration parameter that describes which ones would actually be used. Is any of this practical? Is any of this something that we can get done with existing resources?
