I decided to completely delete everything out of udev's rules file and restart the system. This brought up the devices in whatever discovered order. Then I modified the rules file to set them in the correct order (simply by changing the NAME= key) and rebooted again. Now they're all coming up in the order in which I set them. The mystery MAC hasn't reappeared either. It seems to only be present immediately after the install. I've now rebooted three times to make sure the definitions stick. So far so good. While this has solved the problem, it still doesn't explain the mystery MAC. but, I'm willing to concede that we will never find out where it came from. On Fri, Dec 28, 2012 at 1:07 PM, Ashley M.
