I started implementing this, in the attached v4 patch series.

I tried copying existing code, e.g. the choose-network-service?
part of the tests.

However, it now crashes in a different way when I do `guix environment
guix -- make check-system TESTS=gui-installed-os -j1`:

Subject: [PATCH v4 1/2] installer: Recommend 'ntp-service-type' for
 non-graphical systems.

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.
