+This patch lets GLib's GDesktopAppInfo API watch and notice changes
+to the Guix user and system profiles.  That way, the list of available
+applications shown by the desktop environment is immediately updated
+when the user runs "guix install", "guix remove", or "guix system
+reconfigure" (see <https://issues.guix.gnu.org/35594>).
+
+It does so by monitoring /var/guix/profiles (for changes to the system
+profile) and /var/guix/profiles/per-user/USER (for changes to the user
+profile) and crawling their share/applications sub-directory when
+changes happen.
