Foreman » Installer

foreman installation depend heavily on being able to rerun the foreman-installer after problems. This all goes fine until someone decides to change the hostname. I wasn't aware of the file foreman-answers.yaml and thus ran into a lot of unexpected problems.

• change foreman01.example.com to (pseudocode) $fqdn in the template
• change foreman01 to $hostname
• Provide an option in the installer to change the hostname.
• Document host to perform hostname changes and warn that puppet keys need to be replaced.
