The avahi daemon keeps detecting hostname conflicts #128

Open hnez opened 3 months ago

hnez commented 3 months ago

We have noticed that avahi-daemon sometimes produces a lot of log output because it keeps detecting hostname conflicts:

We should find out why that is and if we even need an avahi-daemon on the TAC or if it can be replaced by systemd-resolved.
