A little off-topic, but the recent addition of this file, along with the matching persistent-net-generator rules caused me some grief. I know that MAC addresses are supposed to be suitable as a way to identify network cards, but everyone also knows that they can be changed easily. In fact, I'm lucky enough that both the built-in interfaces on my MB have invalid MACs (FF:FF:FF:FF:FF:FF and FF:FF:FF:FF:00:00) so the kernel assigns them random MAC addresses. I assign them fixed MACs (<vendor>:FA:CA:DE) and (<vendor>:EF:FA:CE) using the macchanger features of Gentoo's net init script. This had worked since I got the MB, and wasn't something I really wanted to change. With the new udev scripts in place, the pair of interfaces gradually increased their number to eth10 and eth11 (rebooting due to unrelated issues), which made my init scripts so longer run and left me manually starting the interfaces (not fun). I didn't want to delete the files, although I didn't need them, under the fear that they'd just keep coming back. The persistent-net rules script looked quite editable, so I (finally) learned how to write my own, useful udev rules, so force the identification I've always known and loved (ethX by PCI device number). -- Boyd Stephen Smith Jr. ,= ,-_-. =.
