>> I'm not sure what you mean by Role refers RolePermissions, as of now
each role has a list of role permissions linked to it if that's what you're
asking.
With the containment approach, if there is a need to add a permission to
allow say deployVM API on every role then you need to create a permission for
every such role. This will lead to data duplication. Instead if the permission
is created only once and then mapped to all the roles that needs it duplication
won't happen. This is what I meant as reference relationship. Check the
cloudstack DB with table name ending in map t o get an idea. This will also
mean changing the APIs to reflect the same.
