Hello! 

Do we have any advances on this? I can see that the PR is approved, but not more movements on it. Could we know anything?


Regards,
Oscar

something's gone wrong with the unit tests and crio tests. I haven't had time to investigate, and may need to call reinforcements to help. Thanks for your patience

verified in version: 
oc v3.11.317
kubernetes v1.11.0+d4cacc0

run the following script and found no cases:
#!/bin/bash 
docker ps -q | while read line;
do
  if [ `find /var/log/containers -name *$line* | wc -l` = "0" ]
  then
    name=`docker inspect  $line  | grep "Name"  | head -n 1 | cut -d ":" -f 2 | head -c 6`
    if [ $name != '"/k8s' ]
    then
      docker inspect  $line | grep "Name" | head -n 1 
    fi
  fi  
done

Adding my comments from Case 03292252

Also to add more clarification I am the OCP TAM for this customer. The key to this case is they are looking for guidance in developing a custom solution to re-create the sym links as they are worried that their existing custom deployments could possibly break with an upgrade. So what they are looking for is a way, if possible to have a custom script (much like the one provided here that can be modified to re-create those links and possibly be incorporated into a cron job to run at whatever times they deem are safe to run)

Thanks!
