Sure, sounds fine, I just fervently hope that the below is foul swamp gas having nothing what so ever to do with your definition of "saner". http://www.linuxfoundation.org/news-media/blogs/browse/2013/08/all-about-linux-kernel-cgroup%E2%80%99s-redesign http://www.freedesktop.org/wiki/Software/systemd/ControlGroupInterface/ I'm not into begging. I really don't want to have to ask anyone to pretty please do for me what I can currently do all by my little self without having to give a rats ass less whether what I want to do fits in the world view of this or that obnoxious little control freak. -Mike
