To stop Avahi from spamming syslog, copy
/lib/systemd/system/avahi-daemon.service to /etc/systemd/system. Then
edit the newly copied /etc/systemd/system/avahi-daemon.service and add
"StandardOutput=null" to the [Service] section.  Finally, run
`systemctl daemon-reload && systemctl restart avahi-daemon.service` to
make the change take effect immediately.
