Dnsconfd - Systemd is not listening on name org.freedesktop.systemd1

I noticed the following error on my freshly installed Fedora Workstation 42:

Where are you running the code from?
Is it a systemd service or a terminal command line?
If it’s in a service you likely need to turn off a isolation setting.

3

I don’t run it myself, just noticed the error in system journal.

4

Do you need dnsconfd? Or does it just happened to be installed?

Description    : avahi-dnsconfd connects to a running avahi-daemon and runs the script
               : /etc/avahi/dnsconfd.action for each unicast DNS server that is announced on the
               : local LAN. This is useful for configuring unicast DNS servers in a DHCP-like
               : fashion with mDNS.
Vendor         : Fedora Project
5

I’m not sure if I do, I beleive it happened to be installed.

6

In that case you can uninstall it

sudo dnf remove avahi-dnsconfd

dnsconfd is used in special circumstances, so if you need it you would know.
I would not be surprised if this software has bugs if it is not used very often.
