@@ -84,4 +84,6 @@ When mastodon is running in production mode, we have a few problems:
 - mastodon is trying to fetch `missing.png` without ssl (`http://`). This isn't allowed, and i'm not sure why it's doing it.
 - mastodon is trying to fetch `custom.css` from https://mastodon.localhost (no port), which is not the configured `LOCAL_DOMAIN`, so it's unclear why.
 
+NixOS tests do not take the configuration from `virtualisation.vmVariant`. This seems like an oversight since people don't tend to mix normal NixOS configurations with the ones they're using for tests. This should be pretty easy to rectify upstream.
