It's deterministic based on the randomization seed.

A developer must mark structures with the `randomize_layout` attribute and supply a randomization seed for the randstruct feature to be enabled. It's only when a randomization seed is supplied that it'll randomize structures consisting of only function pointers (which happens a lot in Linux). And you're able to opt-out of such a thing.
