FYI, more recently there has been another change that caused "guix
system build" to fail for me, and once again it was fixed by clearing
the auto-compilation cache for my system configuration.

Here's the error I got:

and the relevant excerpt from my system configuration:

       (modify-services (remove (lambda (svc)
                                  (eq? (service-kind svc)

         (guix-service-type config =>
                            (guix-configuration
                              (inherit config)
                              (use-substitutes? #f)

--8<---------------cut here---------------end--------------->8---

I guess that maybe the 'guix-configuration' record was changed, but I
haven't taken the time to find the commit that broke my cached
etc/config-sddm.go.
