That is unfortunate. I view CPUSET is a "first class" option that happens to be built on CONTAINERS. IMO, I shouldn't have to know this implementation detail in order to select CPUSET--indeed, even to be offered the optio--in 'make *config'. However, it will be hidden if I haven't already selected containers. Or do I misunderstand the implications of "depends on"? Andrew: is the problem with select something fatal or just too difficult to fix?
