Indeed! Thanks for bringing this to my attention. Here's my eth0: [ 6.437527] systemd-udevd[1407]: starting version 204 [ 7.457924] systemd-udevd[1428]: renamed network interface eth0 to enp11s0 while my wireless NIC stays named as always was (wlan0): [ 7.822350] b43-phy0: Broadcom 4312 WLAN found (core revision 15) [ 7.838741] b43-phy0: Found PHY: Analog 6, Type 5 (LP), Revision 1 [ 7.838760] b43-phy0 debug: Found Radio: Manuf 0x17F, Version 0x2062, Revision 2 [ 15.771370] b43-phy0: Loading firmware version 666.2 (2011-02-23 01:15:07) [ 15.775217] b43-phy0 debug: b2062: Using crystal tab entry 19200 kHz.
