[bug#47979] [PATCH v6 2/3] installer: Recommend 'ntp-service-type' for n


From: Leo Famulari
Subject: [bug#47979] [PATCH v6 2/3] installer: Recommend 'ntp-service-type' for non-graphical systems.
Date: Sun, 26 Dec 2021 15:31:30 -0500

We had several bug reports with a root cause of "the clock was
incorrect" from users who used the installer to install a non-graphical
Guix System.

* gnu/installer/services.scm (%system-services): Add the ntp-service-type.
* gnu/installer/newt/services.scm (run-system-administration-cbt-page): New
variable.
(run-services-page): Use run-system-administration-cbt-page when not
installing a desktop.
* gnu/installer/tests.scm (choose-services): Add and use a
choose-misc-service?  procedure.
* gnu/tests/install.scm (installation-target-os-for-gui-tests)<services>: Add
ntp-service-type.
