I think yes

Thanks for opening #1115, but I meant adding proper spec for the existing implementation of systemd cgroupsPath, e.g. `user.slice:nerdctl:deadbeef` https://github.com/containerd/nerdctl/blob/07c3ca23743308987aa3b26b1fb7b560804ff9a4/cmd/nerdctl/run_cgroup_linux.go#L53 I didn't mean adding new fields for systemd.

What should happen if the sysctl is also specified but with a different value? Should it fail?

@opencontainers/runtime-spec-maintainers Can we merge this?

@kailun-qin Could you update this PR with the latest revision of https://github.com/opencontainers/runtime-spec/pull/1111 ? Then we can confirm the design of the PRs toward merging. Thanks!
