Running the must-gather logging plugin fails inside the pod with:

/bin/bash: line 17: setsid: command not found

The failure happens because a recent change in the oc client (PR #2087) now wraps the gather command using:

setsid -w bash <<EOF


Minimal must-gather plugin images (including logging) do not include setsid, because util-linux is not installed.
This causes must-gather for logging to fail immediately when the gather script starts.

    100% reproducible when using:


oc adm must-gather --image=registry.redhat.io/openshift-logging/cluster-logging-rhel9-operator@sha256:5f96aaba248207054bdf1dd8dd8e43a2550a210c62367535fb31fa9907c5ee7a   

with an image that lacks setsid
