I'm sure that there will be cases where they will work together like horses in a troika. Making sensible semantics for the interactions is key, and it is entirely possible that in some cases a comparison of semantics and behaviors will lead an end user to chose either an LSM or namespaces over the combination. Just like I expect that even when we allow multiple LSMs the SELinux and Smack combination will be rare among the sane. _______________________________________________ Containers mailing list Containers@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/containers
