Hi Efraim,

What you said makes sense, and I think we are on the right track
here. This is what I have now.

(define-public gnome-custom
  (package (inherit gnome)
    (name "gnome-custom")
    (inputs (alist-delete "nautilus" (package-inputs gnome)))))

;; .......

(services (cons* (service gnome-desktop-service-type
			    config =>
			    (gnome-desktop-configuration
			     (inherit config)
			     (gnome-package gnome-custom)))
		   %desktop-services))


However, it doesn't seem to recognize the gnome-desktop-service-type,
which I know is coming from the desktop service. Perhaps we are defining
it incorrectly? The documentation on the configuration system seems to
suggest we use the gnome-desktop-service and then place the
gnome-desktop-service, and then inherit and set the gnome-custom
package. But I could be misreading it. Regardless, I am still
unsuccessful here.

Thank you for your time.
