- ID for the flavor. This is optional as a unique UUID will be

assigned if a value is not specified.

- The ID of an existing flavor cannot be changed.

- When I(id) is set to C(auto), a new id will be autogenerated.
|

C(auto) is kept for backward compatibility and
|
|
will be dropped in the next major release.
