Description Clayton Coleman 2019-12-03 18:57:00 UTC

+++ This bug was initially created as a clone of Bug #1779331 +++

Init containers were not fully supported in oc debug.  We need to fix that, and also ensure that specific debug options work well with DaemonSet pods.

Confirmed with the latest oc client, the issue has fixed:
