No problem. FWIW, I've been thinking about this cleanup for a while [1].

What I think it may work best is:

Kconfig -> .config -> Makefile (I believe there are some variables we use not only for Ansible)
        -> vars.yaml -> Ansible

But this is another topic.

The correct way would be to add this variable in Kconfig and get it right
away in Ansible with output yaml. If we want playbooks to be reusable outside
kdevops, all these default playbook variables are anyway needed.
