First, given a build like: https://releases-art-rhcos.svc.ci.openshift.org/art/storage/releases/rhcos-4.3/43.81.201911081536.0/x86_64/meta.json

Download the qemu image:
```
$ curl -L https://releases-art-rhcos.svc.ci.openshift.org/art/storage/releases/rhcos-4.3/43.81.201911081536.0/x86_64/rhcos-43.81.201911081536.0-qemu.x86_64.qcow2.gz | gunzip > rhcos-43.81.201911081536.0-qemu.x86_64.qcow2
```

Download new RPM or other content you want, in this case let's assume it's a new hyperkube we want to drop in `/usr/bin`:

`$ curl -L http://example/openshift-hyperkube-4.3.0-201912131246.git.0.09a9468.el8.x86_64.rpm | rpm2cpio | cpio -div`
