User Namespaces
User namespaces are a software architecture concept that allows for the isolation of user and process identities within a system, enabling multiple users to operate in their own distinct environments. This separation enhances security and resource management by ensuring that processes and users do not interfere with each other, even when running on the same underlying system. By leveraging user namespaces, systems can provide a more controlled and flexible environment for application execution and user interactions.
