I've included excerpts from our local scripts/DEBIAN/30-interface file below.  It generates either /etc/netplan/*.yaml or /etc/network/interfaces.d/* or /etc/network/interfaces configuration files as appropriate.

Hi Derek,
thx for the netplan support script.   

There's another problem here, when installing bionic via a stretch NFSROOT:
ifname in stretch is eht0
ifname in bionic is ens160

So install and boot time interface names are different. How did you solve this?

 To me vi is Zen.  To use vi is to practice zen. Every command is
 a koan. Profound to the user, unintelligible to the uninitiated.
 You discover truth everytime you use it.
