• Linux OCI containers as plain FreeBSD jails (without Podman) (2026-08-10)

With a couple of mounts set up to make the extracted root a valid Linux userland, the "container" can run like a regular jail without involving virtual machines or a separate control interface (`podman`). Isolation is handled by the jail subsystem.
