On host in your cosa build directory run e.g.:
```
$ cd /srv/walters/rhcos-4.4
$ python3 -m http.server
```

```
$ cosa run -d rhcos-4.2.0-qemu.qcow2
# ostree remote add --set=gpg-verify=false local http://10.0.2.2:8000/tmp/repo
# while ! rpm-ostree rebase local:tmpref-rhcos; do sleep 0.1; done

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`

cgwalters

Same experimental setup as https://gist.github.com/cgwalters/64752a9544eec662e056f8387a3cefc2#file-ssd-test-md

Based on

[global]
bs=2000
ioengine=sync
iodepth=1
runtime=60
directory=/mnt

cgwalters

First you'll need an initialized cosa workdir:

cosa init https://github.com/coreos/fedora-coreos-config

Now, we need the previous build data: coreos/coreos-assembler#1013

But we can hand-roll that too:

$ buildid=31.20191219.20.1
