Well, in the case of rt-cgroups, it actually is pretty important. (Ok, not so much in the current implementation, but once we have deadline schedulnig in, it will be pretty important). The period decides how quickly your bandwidth will get refreshed, and so define your latency/responsiveness. That is an important tunable. Now, let's say I want to keep the same amouut of bandwidth, but a shorter period. In this case, first I must reduce the budget (the runtime) and then reduce the period. OTOH, when I want to increase the period, then I have to do it in the opposite order. Period first, followed by the budget. Now, in this case dependency ordering matters. If we do not reset it completely, then the configuration files cannot be carefully written to take care of the dependency ordering. So, we are stuck with this. Thanks!
