I know that user namespaces enlarge the attack surface. How much and how serious could be debated but for unprivileged users the attack surface is undoubtedly enlarged. As I read your introduction you were justifying the introduction of a new security mechanism with the observation that distributions were carrying distribution specific patches. To the best of my knowledge distribution specific patches and distributions disabling user namespaces have been gone for quite a while. So if that has changed recently I would like to know. Thank you, Eric
