    I am referring to a hypothetical dockerless OCI compatability layer built on top of `guix shell --container` or `guix system container`. I sort of got this idea from runj [0], an attempt to create an OCI compatible runtime for FreeBSD jails. The main advantage is to use certain OCI-compatible tools (e.g. k8s) with Guix without needing to use Docker. [0] https://samuel.karp.dev/blog/2021/03/runj-a-new-oci-runtime-...
