As an user deploying my own cluster I would like to avoid getting the NFS provisioner configured out of the box without explicitly setting it via vat.tf. In a production deployment I will probably use an already existing or a new NFS server and will include some customization for my deployment to meet some requirements.
I had to execute the following before installing a customized one:
oc delete all -l app=nfs-client-provisioner -n nfs-provisioner
oc delete project nfs-provisioner
