Latest 4.6 nightly:

```
$ oc image info --output json $(oc adm release info -a ~/openshift-cluster-installs/all-the-pull-secrets.json --image-for=machine-os-content  registry.svc.ci.openshift.org/ocp/release:4.6.0-0.nightly-2020-06-16-165419) | jq .config.config.Labels.version
"46.82.202006161324-0"
```

Booting a single RHCOS node from that version:

```
$ coreos-assembler run --qemu-image ./rhcos-46.82.202006161324-0-qemu.x86_64.qcow2 
+ chrt --idle 0 podman run --rm -ti --security-opt label=disable --privileged --uidmap=1000:0:1 --uidmap=0:1:1000 --uidmap 1001:1001:64536 -v /var/home/miabbott/redhat-coreos:/srv/ --device /dev/kvm --device /dev/fuse --tmpfs /tmp -v /var/tmp:/var/tmp --name coreos-assembler quay.io2

So we need to get the 4.6 version of redhat-release-coreos built and tagged properly.

Something is wrong with the ART tags or something:
https://coreos.slack.com/archives/CB95J6R4N/p1592339605407000

This landed in `redhat-release-coreos-46.82-2.el8.x86_64` should be included in latest 4.6 nightly payloads.
