Thanks, good catch! I too figured it wasn't running because nmap reports
closed if the port is open, but nothing's listening on it. So I guess the
firewall configuration survived a reboot, but starting nfs didn't. So
this is needed:
systemctl enable nfs-server.service
Now on to printing.

Yet nmap on another machine shows sshd and nfs open, but shows absolutely
nothing about port 631.
And on that same (redhat) machine, system-config-printer does not see nor
does it find any network printer.
