Talos Linux is a modern Linux distribution built for Kubernetes

> Talos runs in memory from a SquashFS, and persists nothing, leaving the primary disk entirely to Kubernetes.

Also:

> Talos improves security further by mounting the root filesystem as read-only and removing any host-level such as a shell and SSH.

This is not a classical Linux distribution like Core OS and others, it's the equivalent of busybox for Kubernetes.
