The files in /proc/<pid>/fs are 'just symlinks', but opening them can provide access to objects (eg, deleted files) not accessible through the normal filesystem namespace. I see no reason, API-wise, why /proc/<pid>/root couldn't be extended similarly - but I've not looked at the namespaces implementation, so maybe there's some reason it'd be difficult to implement... _______________________________________________ Containers mailing list Containers@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/containers
