We want to allow a resource X to be created without starting it, and then for a group/clone Y to be created referencing X, which can subsequently be started. This ensures that child resources are only started via their parent, respecting the constraints their parent needs to impose (e.g. ordering if the parent is a group). However in this case, changing target-role on Y causes a "Do you want to override target-role for child resource ..." interactive prompt. When STDIN is not a tty, --force is required to ensure that the target-role on the child resource. This only works with newer versions of crm which are patched according to: https://bugzilla.novell.com/show_bug.cgi?id=868697
