excludeFromUpdate for app doesn't override class level setting

[sylim_splunk]

The app level serverclass setting "excludeFromUpdate" does not override high-level settings. Splunk serverclass.conf documentation indicate it should override higher-level settings.

Below is an example of a serverclass called myServerClass. I do not want to exclude anything from the app level, especially for myApp, thus, having an empty value.
The excludeFromUpdate for "yourApp" works fine, overrides the class level configuration.

[serverClass:myServerClass]
excludeFromUpdate = $app_root$/local,$app_root$/default,$app_root$/lookups

[serverClass:myServerClass:app:yourApp]
excludeFromUpdate = $app_root$/lookups

[serverClass:myServerClass:app:myApp]
excludeFromUpdate =

According to the documentation below, it doesn't appear to accept "empty" string for the value and has to be prefixed by "$app_root$".

https://docs.splunk.com/Documentation/Splunk/7.3.1/Admin/Serverclassconf

*excludeFromUpdate = [,]...

• Specifies paths to one or more top-level files or directories (and their contents) to exclude from being touched during app update. Note that each comma-separated entry MUST be prefixed by "$app_root$/" to avoid warning messages. * Can be overridden at the serverClass level. * Can be overridden at the app level. * Requires version 6.2.x or higher for both the deployment server and client.*

Instead, you can work it around by adding non-existing directory, such as "$app_root$/dummy .
