[SOLVED] OH2.3 - KNXD fails to start at boot

Hi,
running the latest snapshot, I can not make knxd run at boot.
I installed and setup knxd via openhabian-config

The following message appears:
[11:27:16] root@openHABianPi:/home/openhabian# service knxd status

A manual start works fine — as you can see!
Any hints?

Solved:

in /lib/systemd/system/knxd.service

the following entry was disabled – after enabling, the service was able to start knxd …
