The current example from the guide has the problem, that in the variables lookup only
os_familyis and nextdistribution+distribution_major_versionis considered.This approach leaves a gap for distributions like Ubuntu or Fedora which don't have their own
os_familybut work vastly different than their root distribution.So if Ubuntu has its own general settings, you would still have to create a vars file for every Ubuntu major version (
Ubuntu_22.yml,Ubuntu_24.yml, etc.).This solution offers the option to have a vars file based on just the
distributionfact (Example:Ubuntu.yml) and solves this gap.
