Is that what you were asking me to do?

Strangely I seem to be able to resolve local names without a suffix
now.  I have rebooted a few machines, maybe something simply got
full/misconfigured and a reboot has cleared it up.  Or, more likely I
suspect, systemd reconfigured something during system updates and the
reboot was needed to get things properly sorted.
