Ubuntu Bionic - Namen der Interfaces umstellen

[FrankM]

Ich teste gerade ein wenig auf einem Mainline Kernel rum.

rock64@rockpro64v2_1:~$ uname -a
Linux rockpro64v2_1 4.18.0-rc5-1052-ayufan-gd1b8f36378ff #1 SMP PREEMPT Mon Jul 30 14:14:58 UTC 2018 aarch64 aarch64 aarch64 GNU/Linux

Dazu habe ich meinen USB3-to-LAN Adapter eingesteckt. Erkannt wird er.

rock64@rockpro64v2_1:~$ ip a

Doch er bekommt so einen Namen enx000acd26e2c8 Das ist jetzt irgendwie neu. Wenn man es so haben will wie früher, also eth0 und eth1 usw., dann kann man das einstellen.

sudo nano /boot/extlinux/extlinux.config

Beim label "label kernel-4.18.0-rc5-1052-ayufan-gd1b8f36378ff" habe ich am Ende der Zeile append folgendes ergänzt

net.ifnames=0 biosdevname=0

Abspeichern, rebooten und die Namen passen.
