If you use Emacs and Emacs-Guix, you can also run:

  M-x guix-default-services

which is really handy.

Another trick is to run:

  guix system extension-graph /path/to/your/config.scm | dot -Tpdf > t.pdf
  evince t.pdf

to view the “service extension graph” for your OS configuration.  That
should give you an idea of what’s included and how these bits interact
with one another.
