Hello Guix!

I don't seem to be able to start Shepherd services from my guix 
home config. The services fail to start, despite being startable 
from the command line from both reconfigure & container.

Here's what my services look like:

#+BEGIN_SRC scheme
(home-environment
 (packages
  (specifications->packages
   (append %base-packages
           %emacs
           %multimedia
           %browsers
           %chat-clients
           %devel)))
 (services
  (list ; ... bash services
        (service home-shepherd-service-type
                 (home-shepherd-configuration
                  (services (list
                             (shepherd-service
                              (provision '(syncthing))
                              (start #~(make-system-constructor 
                              "syncthing"))
                              (stop #~(make-kill-destructor))
                              (documentation
                               "Synchronize folders to other 
                               device"))
                             (shepherd-service
                              (provision '(pantalaimon))
                              (start #~(make-system-constructor 
                              "pantalaimon"))
                              (stop #~(make-kill-destructor))
                              (documentation
                               "Crypto back-end server for 
                               ement.el")))))))))
#+END_SRC

Thanks again for the help & software

Oh! I almost forgot, the error messages from =guix home 
container=. It's worth mentioning that these are /user packages/. 
They're not installed on the root level.

Ok, it seems as though I had some bash configuration issues. My 
"$(inline commands)" made things unhappy for some reason.

I resolved them, and shepherd started working...except that herd 
was totally bound up and not responsive. I had to kill it to 
reconfigure.

I assumed this is because the services were holding stuff up...so 
I tried a forked config:

#+BEGIN_SRC scheme
(service home-shepherd-service-type
                 (home-shepherd-configuration
                  (services (list
                             (shepherd-service
                              (provision '(syncthing))
                              (start #~(make-forkexec-constructor
                                        "syncthing" #:user #:t))
                              (stop #~(make-kill-destructor))
                              (documentation
                               "Synchronize folders to other 
                               device"))
                             (shepherd-service
                              (provision '(pantalaimon))
                              (start #~(make-forkexec-constructor
                                        "pantalaimon" #:user #:t))
                              (stop #~(make-kill-destructor))
                              (documentation
                               "Crypto back-end server for 
                               ement.el"))))))

The forked service does not seem to work :/

The issue is most likely that make-forkexec-constructor's COMMAND
argument expects a list of strings [0]. Try and see if this works:

#+BEGIN_SRC scheme
(service home-shepherd-service-type
                 (home-shepherd-configuration
                  (services (list
                             (shepherd-service
                              (provision '(syncthing))
                              (start #~(make-forkexec-constructor
                                        (list "syncthing") #:user #:t))
                              (stop #~(make-kill-destructor))
                              (documentation
                               "Synchronize folders to other 
                               device"))
                             (shepherd-service
                              (provision '(pantalaimon))
                              (start #~(make-forkexec-constructor
                                        (list "pantalaimon") #:user #:t))
                              (stop #~(make-kill-destructor))
                              (documentation
                               "Crypto back-end server for 
                               ement.el"))))))

Thanks Fredrik!

I really struggle with subtle details that are a few paragraphs 
deep, and so, I am embarassed.

If anyone else is reading this for reference: I should not have 
set =#:user #:t= for =make-forkexec-constructor=. The =#:user= 
keyword expects a string. My user is implicitly when left with the 
default value.

If I may say so, this has been easier to learn than systemd 
services. After many years of mostly failing to use systemd 
properly, I have not yet mastered it.

My user-level services are running :)

Don't be, hard to know where everything is. It took me a while to find
the docs for it as I was first looking for it in the Guix manual.

I'm glad you figured it out! I totally missed the #:user option.

I'm a bit late, but I'm glad to see that its working for you. Here's
what I have in my user services for running syncthing:

(define %syncthing-user-service
  (shepherd-service
    (documentation "Run `syncthing' without calling the browser")
    (provision '(syncthing))
    (start #~(make-forkexec-constructor
               (list #$(file-append (S "syncthing") "/bin/syncthing")
                     "-no-browser")
               #:log-file (string-append #$%logdir "/syncthing.log")))
    (stop #~(make-kill-destructor))
    (respawn? #t)))

I have %logdir defined elsewhere as:
(define %logdir
  (or (getenv "XDG_LOG_HOME")
      (format #f "~a/.local/var/log"
              (getenv "HOME"))))

and S is specification->package.
