How to Use Linux Server Namespaces for Process Isolation

In this episode, Lucas and Luna dive into the practical use of Linux namespaces for process isolation, going beyond the usual container talk. They focus on the mount namespace and how it can prevent a runaway process from clobbering your server's filesystem. You'll hear how a simple unshare command can give you a sandboxed view of the filesystem, and why pivot_root is the missing piece for truly isolated environments. They also touch on how systemd uses namespaces under the hood for service hardening, and how you can test it all safely on a throwaway VM. If you've ever wanted to understand namespaces without the container abstraction, this episode gives you a concrete, hands-on starting point.
