+Wait for configuration und functions
+====================================
+
+[◀ Go back to main README](../README.md)
+
+Description
+-----------
+
+The global scripts `global-config`, `global-config-overlay` and
+`global-functions` are run by scheduler at system startup. Running another
+script at system startup may result in race condition where configuration
+and/or function are not yet available. This script is supposed to wait
+for everything being prepared.
+
+Requirements and installation
+-----------------------------
+
+Just install the script:
+
+    $ScriptInstallUpdate global-wait;
+
+... and add it to your scheduler, for example in combination with
+[bridge-port](bridge-port.md):
+
+    / system scheduler add name=bridge-port-to-default on-event="/ system script { run global-wait; run bridge-port-to-default; }" start-time=startup;
