If a parent group sets min=.2 and max=.8, what are the constraints on
its child groups for setting their resp min and max?

I can't immediately gives rules that would make sense.

For instance, allowing a child to lower min would violate the parent
constraint, while allowing a child to increase min would grant the child
more resources than the parent.

Neither seem like a good thing.
