Added list in CC. I think the end result was, if this file can only be changed by root, then we do not need to worry about namespaces. This file is a privileged file that can only be modified by root. If someday we decide to let non admin users touch this file, then we would need to care about this. This file may actually be modified in the future by users, so this may become an issue. -- Steve _______________________________________________ Containers mailing list Containers@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/containers
