Hey,
I know I have seen my kernel outputting "A renamed to B". Since you two however wanted that information in the first place, I grepped a bit around, and actually found, (drumroll), that the SUSE kernel has had a proper patch for [I can't remember how long] quite some time. (At least one distro which does the right thing.) I copied it below.
Jan === Name: patches.suse/nameif-track-rename.patch Subject: [PATCH] keep track of network interface renaming From: Olaf Hering <olh@suse.de>
Keep track about which network interface names were renamed after the network device driver printed its banner. Example insanity:
honeydew:~ # dmesg| grep -Ew '(eth[0-9]|rename|renamed)' e1000: eth0: e1000_probe: Intel(R) PRO/1000 Network Connection e1000: eth1: e1000_probe: Intel(R) PRO/1000 Network Connection e1000: eth2: e1000_probe: Intel(R) PRO/1000 Network Connection e1000: eth3: e1000_probe: Intel(R) PRO/1000 Network Connection dev_change_name: about to rename 'eth3' to 'eth0' dev_change_name: about to rename 'eth3' to 'ethxx3' eth3 renamed to ethxx3 dev_change_name: about to rename 'ethxx3' to 'eth0' dev_change_name: about to rename 'eth0' to 'eth3' eth0 renamed to eth3 dev_change_name: about to rename 'eth1' to 'eth2' dev_change_name: about to rename 'eth1' to 'ethxx1' eth1 renamed to ethxx1 dev_change_name: about to rename 'ethxx1' to 'eth2' dev_change_name: about to rename 'eth2' to 'eth1' eth2 renamed to eth1 dev_change_name: about to rename 'ethxx3' to 'eth0' ethxx3 renamed to eth0 dev_change_name: about to rename 'ethxx1' to 'eth2' ethxx1 renamed to eth2 e1000: eth0: e1000_watchdog_task: NIC Link is Up 100 Mbps Full Duplex
