Description Clayton Coleman 2020-09-04 16:59:28 UTC 
A community member reported that the pod image does not correctly reap readiness checks when pods are used with shareProcessNamespace.  In the future we may use a systemd image, but for now our pod image should work correctly.

We need to review the change and verify it is equivalent to pause.c in upstream Kubernetes.

I have tested the PR and left review comments which are being addressed. It is close to getting merged. Hopefully, it will land today or early next week and be available for testing.
