 | By default this plugin is using a general group name sanitization to create safe and usable group names for use in Ansible. This option allows you to override that, in efforts to allow migration from the old inventory script. For this to work you should also turn off the TRANSFORM_INVALID_GROUP_CHARS setting, otherwise the core engine will just use the standard sanitization on top. This is not the default as such names break certain functionality as not all characters are valid Python identifiers which group names end up being used as. | |

Hint
Configuration entries for each entry type have a low to high priority order. For example, a variable that is lower in the list will override a variable that is higher up.
