Title here
Summary here

An immutable Linux distribution that boots into a Kubernetes node. Built on bootc, ships k0s, configured with cloud-init.
Built with a Containerfile, pushed to a registry, versioned by
digest. Inspect it, scan it and promote it with the tooling you already use.
k0s lives in the read-only /usr.
Upgrading Kubernetes means booting a new image, with one rollback path.
No bespoke API and no new configuration language. Where cloud-init does not exist, the same schema is read from a file or the kernel command line.
A verbatim k0s patch, and an ordinary cloud-config underneath. Corium is a guest in your configuration, not its owner.
