StarlingX specific OCF scripts (ie: OCF scripts that are not from the OpenStack foundation) should be packaged in the StarlingX repos and not in the stx-staging repos. The following 9 Distributed Cloud OCF scripts should be moved from openstack-ras into the distributedcloud-dcorch rpm built from the openstack/stx-distcloud repo: dcmanager-api dcmanager-manager dcorch-cinder-api-proxy dcorch-engine dcorch-neutron-api-proxy dcorch-nova-api-proxy dcorch-patch-api-proxy dcorch-snmp dcorch-sysinv-api-proxy Change-Id: Ic7b040733e8df66bdd79d45675d63e58abbd85e1 Story: 2003715 Task: 26374 Signed-off-by: Scott Little <scott.little@windriver.com>
