The ReadOnlyRootfs parameter, introduced in API 1.17, seems to only be taken into account when passed to the containers/create endpoint. The documentation, as well as the behavior of all other HostConfig parameters suggests that it should also be recognized when passed to the containers/<id>/start endpoint, but it doesn't look to be the case.
Let me know if you need more details about this particular issue. Happy to help in any way I can.
