Hi,

Sergey Trofimov <sarg <at> sarg.org.ru> skribis:

Nice!

Note: You can just say “New file” for a new file; however please specify
the name of the node added to the manual, for clarity.

> +(define syncthing-home-shepherd-service
> +  (lambda (configuration)
> +    (map (lambda (srv) (shepherd-service (inherit srv) (requirement '())))
> +         ((@@ (gnu services syncthing) syncthing-shepherd-service) configuration))))

You could do that without resorting to @@, by using ‘find’ on the
extensions of ‘syncthing-service-type’.

> +  (user      syncthing-configuration-user)     ;string

This means that users of ‘syncthing-service-type’ will now have to
provide a value for ‘user’, which wasn’t the case until now.  Is this
change necessary?

The rest looks reasonable to me.  My main concern is whether it would
make sense to automate system->home service translation.  I’ll expand on
that separately.

Thanks,
Ludo’.
