There is a minor typo omission in the code configuration example. the line that contains the command with `cliwrap` needs a `&&` at the end:

```
# Using a 4.12.0 image
FROM quay.io/openshift-release/ocp-release@sha256...
#Install hotfix rpm
RUN rpm-ostree cliwrap install-to-root / \
    rpm-ostree override replace http://mirror.centos.org/centos/8-stream/BaseOS/x86_64/os/Packages/kernel-{,core-,modules-,modules-extra-}4.18.0-483.el8.x86_64.rpm && \ 
    rpm-ostree cleanup -m && \
    ostree container commit
```

so the fix would look like:

```
# Using a 4.12.0 image 
FROM quay.io/openshift-release/ocp-release@sha256...
#Install hotfix rpm 
RUN rpm-ostree cliwrap install-to-root / && \
    rpm-ostree override replace http://mirror.centos.org/centos/8-stream/BaseOS/x86_64/os/Packages/kernel-{,core-,modules-,modules-extra-}4.18.0-483.el8.x86_64.rpm && \ 
    rpm-ostree cleanup -m && \ 
    ostree container commit
```
