+Subject: [PATCH] Load configs from /etc but fallback to /nix/store
+
+This change will load all configuration files from /etc, to make it easy
+to override them, but fallback to /nix/store/.../etc/sway/config to make
+Sway work out-of-the-box with the default configuration on non NixOS
+systems.
+
+Original patch by Michael Weiss, updated for Sway 1.6 by Patrick Hilhorst
