I think he meant "there is a CONFIG to special-case Yama", but yes, Yama is a good example. Now that finit_module has landed, I intend to send another micro-LSM to provide logic for blocking modules when the root devices is read-only.
It would be another example of an LSM that needs to be stacked with others.
