I see you now chose to add a jail option, certainly the cleanest solution. Will test later today. Just to make sure I have the correct expectation about the behavior with the new patch applied: * Unprivileged user will get ENOTSUP when trying to access the system namespace (regardless of the new jail setting), so GNU tools like e.g. coreutils install should "just work". * Root will get either ENOTSUP, or a fully working access to system.* with the new jail setting enabled. Are these assumptions correct?
