If anyone else would like to use the new bayfront substitute server by
declaring it in their config.scm you can consult the config I'm using
below, which is based on the lightweight desktop config base.

The important bits added are (guix-store) and (gnu services base) in the
topmost (use-modules ...) sexp, as well as in the modified (services ...) one.

Thanks for those who offered guidance on how to do this in the #guix irc
channel!
