Yes that is correct `docker build -t <tag> .` with a local docker
daemon.

This is a nice feature.

It seems odd that a service does not take care of services it needs.
It makes me think of a package that does not include the dependencies it
needs to run.

Thank you for this suggestion.  There is a lot in %desktop-services that
I do not need on my system.  I am also trying to explicitly state
imports so that I can learn more about the parts of the Guix repository
I am using.

Thank you for pointing this out.

I am aware of these features and plan to explore them.
