 These examples do not need the "_default" because they use
 the "run_list" attribute to set the default run list. Something like
 this:

>  "env_run_lists": {

>    "preprod": [],

 So you do not need to create a "_default" key there. This is equivalent
 to:

>  "env_run_lists": {
>    "default": [ "role[base]", "recipe[apache]" ],
>    "production": [],
>    "preprod": [],
>    [...]

 I know this can be confusing.

 IMHO we should clarify this in the "env_run_lists" and "run_lists"
 sections.
