This removes a fair amount of NXDOMAIN error noise in journalctl. Observing the issue and the fix requires 3 terminals: 1. tcpdump -i any 'port domain' 2. journalctl --boot -u systemd-resolved -f 3. nmcli c down "Wired connection 1"; nmcli c up "Wired connection 1" => observe the NXDOMAIN noise over a couple few minutes Now make the hostname absolute with the trailing dot above and run: systemctl reload NetworkManager Wait 1 min for things to stabilize. Test again: nmcli c down "Wired connection 1"; nmcli c up "Wired connection 1" => observe non-zero but significantly reduced NXDOMAIN noise over a couple few minutes Originally reported at https://askubuntu.com/a/1242611/117217 Plenty of people annoyed by NXDOMAIN warnings, just Google it.
