sysctl: add sysctl to disallow unprivileged CLONE_NEWUSER by default
add sysctl to disallow unprivileged CLONE_NEWUSER by default This is a short-term patch. Unprivileged use of CLONE_NEWUSER is certainly an intended feature of user namespaces. However for at least saucy we want to make sure that, if any security issues are found, we have a fail-safe.
