Last time such a patch came up I was not thrilled because hiding a scary feature behind a knob IMHO doesn't make it any better nor helps finding issues. But as userns is still a source of a lot of issues and distros enable it by default a knob for the admin seems to be a good idea by now. ;-\ Thanks, //richard -- To unsubscribe from this list: send the line "unsubscribe linux-doc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
