-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.
-
-Do **not** add this script `global-wait` to the `global-scripts` scheduler!
-It would inhibit the initialization of configuration and functions.
-
-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;
