Hey Jakob/Chris,
I can't comment on much of the deploy code, but I can help out
with some stuff about the Shepherd.

There was discussion earlier this year around restarting services
that are already running during a reconfigure[1]. I wonder if this
problem is more worth solving if we're deploying to remote
systems. I have a few patches in that issue to implement service
restarting, but I didn't follow them up enough to get them into
Guix.

The Shepherd will start any necessary dependencies in an
appropriate order.
