[bug#47979] [PATCH] installer: Recommend 'ntp-service-type' for non-graphical systems.

[Mathieu Othacehe <othacehe@gnu.org>]

Hey Leo,

> +(define (run-system-administration-cbt-page)
> +  "Run a page to select various system adminstration services."
> +  (let ((items (filter (lambda (service)
> +                         (eq? 'administration
> +                              (system-service-type service)))
> +                       %system-services)))
> +    (run-checkbox-tree-page
> +      #:title (G_ "Miscellaneous services")
> +      #:info-text (G_ "Select miscellaneous services to run on your system.")
> +      #:items items
> +      #:selection (map system-service-recommended? items)
> +      #:item->text (compose G_ system-service-name)
> +      #:checkbox-tree-height 5
> +      #:exit-button-callback-procedure
> +      (lambda ()

Indentation is off here, 

> +     ;; Miscellaneous system administration services.
> +     (system-service
> +       (name (G_ "Network time service, to set the clock automatically"))
> +       (type 'administration)
> +       (recommended? #t)
> +       (snippet '((service ntp-service-type))))
> +

here, 

> +     (system-service
> +       (name (G_ "GPM mouse daemon, to use the mouse in the console"))
> +       (type 'administration)
> +       (snippet '((service gpm-service-type))))

and here. Those patches are breaking the installer tests because they
introduce a new dialog. You need to add something like:

--8<---------------cut here---------------start------------->8---
    ((checkbox-list (title "Miscellaneous services") (text _)
                    (items ,services))
     (filter choose-misc-service? services))
--8<---------------cut here---------------end--------------->8---

in the (gnu installer tests) module, to fix this error:

--8<---------------cut here---------------start------------->8---
conversation expecting pattern ((quote list-selection) ((quote title) "Partitioning method") ((quote multiple-choices?) #f) ((quote items) (not-encrypted encrypted _ ...)))

Otherwise, it looks fine :)
