commit: https://git.buildroot.net/buildroot/commit/?id=5ec9542415c92584fe0b986feea6326375bd63b6 branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master This patch adds runtime testing of the OCI archive created by the sloci scripting. It launches a containerd instance, imports, and runs the OCI container. The existing QEMU AARCH64 kernel config was extended to enable common options used by a container runtime (cgroup and overlayfs).
