Hi!

Ever since Efraim's excellent blog post
(https://guix.gnu.org/en/blog/2020/gnu-shepherd-user-services/) I have been
willing to try Shepherd's User Services (actually I wanted to try it for much
longer but it felt too daunting to dive in), and thanks to a nice discussion
on IRC this morning I finally gave it a go.

We were wondering it if would be feasible to add

--8<---------------cut here---------------start------------->8---
if [[ ! -S /run/user/$UID/shepherd/socket ]]; then  
    shepherd  
fi  
--8<---------------cut here---------------end--------------->8---

to /etc/skel/.bash_profile, and maybe even add
/etc/skel/.config/shepherd/init.scm:

--8<---------------cut here---------------start------------->8---
(use-modules (shepherd service)
             ((ice-9 ftw) #:select (scandir)))

;; Load all the files in the directory 'init.d' with a suffix '.scm'.
(for-each
  (lambda (file)
    (load (string-append "init.d/" file)))
  (scandir (string-append (dirname (current-filename)) "/init.d")
           (lambda (file)
             (string-suffix? ".scm" file))))

;; Send shepherd into the background
(action 'shepherd 'daemonize)
--8<---------------cut here---------------end--------------->8---

that I got from Efraim's blog post.  For starters, I have put this
in the Shepherd manual.  WDYT?

Greetings,
Janneke

Finally pushed; I changed ‘%user-cache-dir’ references to
‘%user-log-dir’:
