The Foreman installer can be intimidating at first. It manages lots of files, and has many, many, many options. Even more options are exposed via
custom-hiera.yaml. If you want to make a change that’s not covered by either an installer option or
custom-hiera.yaml, you may feel like you are out of luck. However, this is a great opportunity to make an upstream contribution!
