What do you think of adding some validation code to 'service-type'
and the "guix home" equivalent, e.g. a ‘validate’ field, which
could be used like

(define-module (...)
  #:autoload (gnu home??? mcron) (mcron-user-configuration?))

(define mcron-service-type
  (service-type (name 'mcron)
                ...
                (validate
                  (lambda (config)
                    (cond ((mcron-configuration? config) #t)
                          ((home-mcron-configuration? config)
                           ;; TODO: figure out a clear error message
                           (validation-error (G_ "A mcron configuration for the system was expected, but a configuration for the user was used")))
                          (#t #f))))))

and likewise for the "guix home" equivalent, such that if user configurations
are used in the system configuration, an error message is printed, indicating
the issue?  Maybe include the line and column number of the record as well.

Greetiings,
Maxime.
