+Subject: [PATCH] meson: always install network example files
+
+I started working on integrating this in the Fedora package and realized that
+the example files should be installed regardless of the renamed files when
+default-network=true is used. This is because the renamed files become part of
+a different package, and we want to have the other files which are used as
+documentation in the main package anyway.
