up ip link set eno1 up
Die brigde ist "up",
die IP ist vorhanden,
eno1 ist nicht in der Interface-Datei konfiguriert,
bekommt aber trotz Zugehörigkeit zu br0 eine lokale IP!?
Daher funktioniert vermutlich auch der Ping ins inet nicht?

Jetzt nehme ich die br0 raus und konfiguriere eno1 statisch:

Und nach einem reeboot hat dieses verfluchte Interface wieder eine dhcp Adresse statt der statisch konfigurierten!
Ich verstehe es nicht.
