For me, it is the other way around: it makes perfect sense to have a per-subtree selection of features where it doesn't hurt us, provided it is hierarchical. For the mere fact that not every application is interested in this (Michal is the one that is being so far more vocal about this not being needed in some use cases), and it is perfectly valid to imagine such applications would coexist. So given the flexibility it brings, the real question is, as I said, backwards: what is it necessary to make it a global switch ? _______________________________________________ Devel mailing list Devel@openvz.org https://openvz.org/mailman/listinfo/devel
