-Re: Discussion on Namespace permissions

It is absolutely useful to grant users full access within a namespace and
no access outside of it. If I'm running some experiments then let me (and
possibly the rest of my team) create and drop to heart's content in our own
personal area and don't worry about the rest of the system.
Having a permission to create namespaces is also good because you can then
separate various facets of system administration. Kind of. Since only root
can grant, you still can't have a delegated user create and assign
namespaces to other users, but this is a step towards a decentralized
