@brandond It's strange but apparently it compiles just fine on Windows with stock runc, meaning the change at k3s-io/runc@688fdd8 is not really needed.

Ah! I found it. By the way, here is the original windows builld error: ttps://drone-pr.k3s.io/k3s-io/k3s/8400/1/4. It comes from k8s.io/pkg/kubelet which imports runc/libcontainer/userns from runc v.1.1.12.

The same issue was fixed in k8s in a different manner: kubernetes/kubernetes@2e999ff (PR kubernetes/kubernetes#122652). This is k8s v1.30; from what I see, older k8s branches (1.29, 1.28, ...) never updated to runc > 1.1.10.

Also, runc itself split the internal part of userns functionality into a separate package here: opencontainers/runc#4331 (made its way to runc v1.2.0, was not backported to any 1.1.x).

Finally, the RunningInUserNS functionality was moved out of runc and into https://github.com/moby/sys (userns package) here: opencontainers/runc#4350, moby/sys#140, moby/sys#145. This is also in runc 1.2 and not backported to older releases.

So, to summarize, the fix (like k3s-io/runc@163700f) is not needed since runc v1.2.
