+  * Fix the start of vpn-router-setup hanging on a host that runs Docker.
+    vpn-router-setup restarted vpn-router-docker and waited for it, but that
+    unit was ordered after vpn-router-setup, so each waited for the other,
+    the installation of the package never finished and vpn-router-web was
+    never enabled or started. vpn-router-docker is no longer ordered after
+    vpn-router-setup, so vpn-router-setup still waits for it and the Docker
+    rules are in place when it ends. The restart of vpn-router-web is queued
+    without waiting.
+  * Start vpn-router-setup after docker.service, so that Docker is up when
+    the setup looks for it and does not start in parallel with it. The
+    ordering applies only when Docker is installed.
