+
+rkt is a pod-native container engine for Linux. It is composable, secure, and built on standards.

+#### Add support for the OCI runtime spec by implementing a runc stage2
+
+- Description: rkt implements the App Container Executor specification of the [appc Container Specification](https://github.com/appc/spec) and uses systemd unit properties to implement its features. To implement the OCI runtime spec, systemd unit properties are not suitable since they differ from what the spec defines. The idea is to replace systemd unit properties by runc to implement the OCI runtime spec. Work for this [has already started](https://github.com/rkt/rkt/issues/3408).
+- Recommended Skills: Golang.

+
+#### Add native OCI image support
+
+- Description: rkt supports the OCI image spec by converting an OCI image to its internal format (appc). The idea is to implement native support for the OCI image spec using the [containers/image library](https://github.com/containers/image). This will also involve coming up with a reasonable scheme to support both appc and OCI images, and refactoring rkt's image store and fetching logic.
