Hello, I'm running the latest Tumbleweed on a Lenovo Thinkpad T440s. I need the Avahi services to discover and connect to WiFI networked printers. But when I tried to enable the "avahi-daemon" and avahi-dnsconfd services via YAST, I heard the hard disk thrashing for several minutes, and I finally had to power cycle the system. I tried again via YAST and the same thing happened. So next I tried the command:

systemctl enable avahi-daemon

...which causes the same error output over and over in an apparently infinite loop:

""""""""
Synchronizing state of avahi-daemon.service with SysV init with /usr/lib/systemd/systemd-sysv-install...
Executing /usr/lib/systemd/systemd-sysv-install enable avahi-daemon
""""""""

This command is repeated over and over again every 1-2 seconds. I was able to force stop it with ctrl+C, at which point it repeats this other error many times repeated:

""""""""
Note: This output shows SysV services only and does not include native
systemd services. SysV configuration data might be overridden by native
systemd configuration.

If you want to list systemd services use 'systemctl list-unit-files'.
To see services enabled on particular target use
'systemctl list-dependencies [target]'.
""""""""

The same thing happens with the service "avahi-dnsconfd". This does not happen with other services, either managed by systemctl or YAST Services.
