>I’m trying to make my home configuration more modular, so I can better support system variances. For example, I have a laptop I use interactively, and a headless machine that runs Cuirass. It’s advantageous to share certain aspects of the home configuration between the two machines (shell prompt/environment, GPG agent, etc), but not others (anything X11/graphical stuff shouldn’t be on the build machine). One approach to this is to define packages and services and reference them in the home configuration. What I dislike about this is that many things require both packages and services, and I’d prefer to have a way to completely encapsulate that -- for example, the mpd-mpc package to control my music server, plus a home-environment-variables-service-type to set MPD_HOST.

>Surprisingly, this doesn’t work -- it complains that there’s more than one "home" service type. I’m not sure why that is, and I haven’t been able to see anything obviously wrong in the REPL -- though I haven’t been able to get my actual home configuration up in the Emacs-Guix REPL, due to #67290.
