For anyone who cares about resource control setting up the memory
control group in combination with user namespaces is strongly
recommended.
User namespaces are a particular problem when it comes to resource
control. Not all of the resources you can create with a user namespace
currently have ordinary resource limits. When you can switch uids
the ordinary resource limits don't mean much.
The memory control group is capable of limiting all of those things
today. So if you care about keeping rude users of your system under
control and you enable user namespaces setting up memory control groups
is to limit them is strongly recommended.
