That would make my kernel builds etc interfere with my other self's surfing and whatnot. With it by EUID, when I'm surfing or whatnot, the X portion of my Joe-User activity pushes the compile portion of root down in bandwidth utilization automagically, which is exactly the right thing, because the root me in not as important as the Joe-User me using the GUI at that time. If the idea of X disturbing root upsets some, they can move X to another UID. Generally, it seems perfect for here. -Mike - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
