Subject: [PATCH 5/7] services: shepherd: Use the 0.10.x GOOPS-less interface.

From: Ludovic Courtès <[email-masked]>
Date: Fri, 5 Jan 2024 11:59:32 +0100

* gnu/services/shepherd.scm (%default-modules): Remove (oop goops).
(shepherd-service-file): Use (service …) instead of (make <service> …).
Use ‘actions’ instead of ‘make-actions’.
(scm->go): Remove use of (oop goops).
(shepherd-configuration-file): Pass ‘register-services’ a list.
Use ‘start-in-the-background’ unconditionally.
