instead attempt to directly upload archives to the referenced case, thus
streamlining the process of providing data to technical support engineers.
If either or both of the credentials or case number are omitted or are
incorrect, then a temporary anonymous user will be used for upload to the

The one change is that this policy ensures that sos collect will deploy a
container on RHCOS systems in order to facilitate sos report collection,
as RHCOS discourages non-default package installation via rpm-ostree which
is used to maintain atomicity for RHCOS nodes. The default container image
used by this policy is the support-tools image maintained by Red Hat on
registry.redhat.io.
Note that this policy is only loaded when sos is directly run on an RHCOS
node - if sos collect uses the `oc` transport (the default transport that
will be attempted by the ocp cluster profile), then the policy loaded
inside the launched pod will be RHEL. Again, this is expected and will not
impact how sos report collections are performed.
