I don't get it: people like that will sink and waste hundreds of hours learning useless garbage like Puppet, Ansible, Chef, Docker or Kubernetes without batting an eyelash or even thinking twice about it, but they'll argue and fight back like hell come time to deliver their software as clean OS packages because they don't want to learn the technology. Technology which exists for them first and foremost: OS packaging is meant to be a developer's tool and best friend.
