The description for installing `butane` for use in generating the configs is specific to RHEL/Fedora based systems. It also does not take into account the version of `butane` available in the host OS package repository.

Case in point, while the command works on RHEL9.2, the version of `butane` installed is `0.17.0`. This version only supports generating configurations up to and including OpenShift 4.12. As this documentation is for OpenShift 4.16, the input file cannot be processed by `butane`.

    All versions of OCP 4 and all versions of butane

    Very

    1. On an older RHEL/Fedora host, install `butane` as per the steps in the OpenShift documentation
    2. Create a `butane` input file based on the example given
    3. Run the `butane` command to convert the config file into a yaml file to import into OpenShift
    

    The `butane` command gives an error and does not generate the OpenShift compatible yaml:

```
$ butane 99-master-chrony.bu -o clusterconfigs/99-master-chrony.yaml
Error translating config: No translator exists for variant openshift with version 4.16.0
```

    The command works and an OpenShift yaml file is generated

    A workaround exists to specify an older OpenShift version in the butane input that is supported by the version of butane in use, but you then have to know what versions will work and then modify the generated output, defeating the purpose of the generator in the first place
