It's a good first pass. To be refined later.
To avoid wasting your time, I'll skip answers to questions that have
been dealt with in other mail, also simple typo fixes.

By hypothesis our connection is wired.
I'm seeing much faster bootup than this - I don't think I've had to wait
for ssh availability longer than 30 seconds. I wonder what accounts
for the difference?

When did this happen? When did usermod become a thing? It's a great idea
but I had no idea it existed until just now.
Will do.

I'm not sure if it's necessary, but it seems like a good belt-and-suspenders
move.

Raspbian does. So does the Odroid, and so does Beaglebone. That's enough range
for now.

Revised.

It's premounted in the lastest Jessie Lite image. Under what circumstances
might it not be?

LED blink interval in seconds - telly you fix vs no fix.

Will a later git pull work on a repo pulled this way?
