Description Nico Gulden

As app developer I want to use the app installation process in order to check user input from app settings. Depending on the check results, the app installation is continued or aborted and the user receives a custom message on command line and in UMC.

This requires that app settings are requested from the administrator before any app life cycle scripts run. And the app settings values need to be available on UCS before the pre-inst script runs. This makes only sense for app settings in outside scope, though.

The pre-inst script is currently the only script in the context of the UCS system during app installation whose error code can result in aborting the app installation.
