But I have what is at least for me a unifying concept, that makes things easier to think about. The idea is to think about things in terms of namespaces. Currently in the kernel we have the fs/mount namespace already implemented. Partly this helps on what the interface for creating a new namespace instance should be. 'clone(CLONE_NEW)', and how it should be managed from the kernel data structures. Partly thinking of things as namespaces helps me scope the problem. Does this sound like a sane approach?
