Subject: [PATCH v2 3/4] weather: Use the same substitute URLs as guix-daemon.
Date: Mon,  4 Dec 2023 15:15:44 +0100

* guix/scripts/weather.scm (%default-options): Remove ‘substitute-urls’.
(guix-weather): Call ‘substitute-urls’ when OPTS doesn’t have it.  Warn
when ‘substitute-urls’ returns #f.
* doc/guix.texi (Invoking guix weather): Adjust accordingly.
