That does seem odd.  Why were you prompted for an email address?  Can
that be fixed somehow?

Where is the certbot-service-type defined?  I couldn't find it in the
master branch.  Also, why is mcron required?  I don't know much about
LetsEncrypt, but I thought certbot was a one-time thing that you do
manually...  Why is it a "service" here?

I wonder if it is possible to define a custom service which orchestrates
the execution of nginx and certbot in the way you require, so that you
can define it all in one place, at once, without needing to reconfigure
multiple times?

Pretty cool!  Thanks for sharing your experience.  It's always neat to
read about how people are using the system.
