Voraussetzung: Falls NetworkManager läuft, Interfaces aus der Konfiguration herausnehmen:

/etc/NetworkManager/NetworkManager.conf

[device]
match-device=interface-name:enp0s31f6
managed=0

Datei(en) anlegen

• *.netdev = Gerätdefinitonen, z.B bridges und bonding
• *.link = Link Layer, z.B. Namen, MAC und MTU
• *.network = Netzwerk (L3)

/etc/systemd/network/ethauto.network
