Comment 10 Trevor Jay 2018-07-07 05:54:22 UTC 
The tracking and other problems surrounding this issue are entirely my fault. I thought of this more as an OCI/compliance issue and directly went against Red Hat policy on upstream disclosure. It was my *wrong* call. If there's any remaining loose ends from that fallout, please let me know.

I think we are tracking correctly now (special thanks to everyone who got cri-o marked affected especially).  Like I said: if anything else has fallen between the cracks, let me know so I can get some grout.

Is it too late to fix a typo? Should be "default"
