Customer reported:

I installed Fuse Online according to the following instructions: https://access.redhat.com/documentation/en-us/red_hat_fuse/7.2/html/integrating_applications_with_fuse_online/how-to-install-on-ocp_ug
When installed this way it is installed with demo data (sampleDB) and demo app (ToDo app) and a preconfigured connector to the demo database.
How can I install Fuse Online without the demo data and demo app?

The closest thing I could find is in the configmap syndesis-server-config in the application.yml:
deployment:
load-demo-data: false

But as this is already default set to false it does not have any effect apparently.
