Ah, OK.  Sorry about that!  I thought systemd had taken over that 
functionality.

Attached as "networking.service-status.txt" and 
"ifup at eth0.service-status.txt".

Yes it does!  If I switch to "auto eth0", then everything will correctly 
wait for the network connection to come up before continuing to boot.

I have attached "post-interface-change-networking.service-status.txt" to 
show the output of `systemctl status networking.service` after I changed 
from "allow-hotplug eth0" to "auto eth0".
