"Container" is a > marketing term used by some userspace tools. No, its a real thing just like a login. Does the kernel have any concept of a login? Yet it happens. And it causes us to generate events describing who, where from, role, success, and time of day. :-) > I can imagine that both audit could benefit from a concept of a > namespace *path* that understands nesting (e.g. root/2/5/1 or > something along those lines). Mapping these to "containers" belongs > in userspace, I think. I don't doubt that just as user space sequences the actions that are a login. I just need the kernel to do some book keeping and associate the necessary attributes in the event record to be able to reconstruct what is actually happening. -Steve -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
