When you use the API to create index stanzas on a master, it places it in .../system/local/. API endpoint:
The best practice to deploy this config with a cluster bundle is to copy it from that directory and into .../master-apps/_cluster/local/ https://answers.splunk.com/answers/387133/how-to-create-index-using-rest-api-in-a-clustered.html
Instead, could we symlink the directories together so OS level access to copy the file over is never needed in the first place? In other words, does apply cluster-bundle work if we symlinked the master-apps directory?
