[[info:shepherd][The Shepherd manual]] suggests that you use a single =init.scm=, but as is pointed out by this article about [[https://guix.gnu.org/en/blog/2020/gnu-shepherd-user-services/][GNU Shepherd user services]] it might be better to have the services in separate files so you can restart them individually if you make any changes to them. So I just put a loading script into =init.scm= that goes through the =init.d= directory and loads each service defined in there.

#+begin_src scheme
(use-modules (shepherd service)
             ((ice-9 ftw) #:select (scandir)))

(for-each
 (λ (file) (load (string-append "init.d/" file)))
 (scandir (string-append (dirname (current-filename)) "/init.d")
          (λ (file) (string-suffix? ".scm" file))))

(action 'shepherd 'daemonize)
#+end_src
