User namespaces isolate security-related identifiers and attributes, in particular, user IDs and group IDs, the root directory, keys, and capabilities. A process's user and group IDs can be different inside and outside a user namespace. In particular, a process can have a normal unprivileged user ID outside a user namespace while at the same time having a user ID of 0 inside the namespace; in other words, the process has full privileges for operations inside the user namespace, but is unprivileged for operations outside the namespace.
