Udev, as of version 187, will now refuse to rename a network interface to the name of a network interface that already exists -- which, due to race conditions, can be the case if you are attempting to rename a network device to a name the kernel will later use to name the next enumerated device. The fix for this issue is to *not* use names that match "eth[0-9]*", "wlan[0-9]*", etc. and instead use a name that the kernel would *not* automatically assign. Unfortunately, that means that you *cannot* keep your old names and order (upstream claims that the means used to ensure those names were used was unreliable and prone to race conditions anyway, which, looking at the code, I can believe). - -- Jonathan Callen -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.19 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQIcBAEBCgAGBQJRRHYFAAoJELHSF2kinlg4d0MQAJhJs73Nlja+TGoq77TaYMOz vrJmZmPDewp+1imFjfnddhC6c5ePn5+XCQ7vWmcB3LVVh8JAOqRq1pEV/u4F3HYO 8VE5VI/s0K2MO/+8aLOOSnB91tmEmZ9ziKnIjvZPKqDKH5JB2iCShnvvgfdWIlQB HwaZknzlvl1bNCBmDfaXFoGzPmEIiyIysuzI9xFxv1/m+VOMeDkN5a7qJmC7mXld gu9Shx15Y2LBJZvQaUH8aM6Qv4BsMc9IJ0XWp/aHpbefMuj+Vb5038caRRfHqyUN aNmYmiEvvkb2IqrMSJ8x4faC3iVj/YimovEQhiDZmwaHcl2IqmlngJ1qAPk30/Lh fwUVDCTwtJ/zoOoTxGpd4zZ/wUVVPaupsOc2D7ZMXlw2o5RzsuSwRE5FrHv/0MXO Ne3I3QVHvPJvYfwi0AyOv5wHEKkCdF9MjgWqCErjEPaFUrrPuiWp4ESQp/HE5rVQ YG77ZSugSnFddZgwYenlSgDhHkkMaHV8zeNautVOPRMsvqbKbnVjEtT7YXHJBN0B OnnCQhZR7lBKCkxc5Xq/TWXe9imT/1Of8tLn80SuICthUGLgFg1tlv0AIjKmWU9q FIoQ+xD6rTav2zdPkTF86HsODqwe38br64NLPhUSfd+s7e5iiqh++XTtwTnXSKXW QbQb+npPnCZ0DgqW9aCM =/24C -----END PGP SIGNATURE-----
