> Also using {{CAMEL_COMPONENT_AWS2-S3_ACCESSKEY}} is not an option as it won't work and uses non-allowed characters for environment variables.

> In the thread the following suggestions where made by [~cibsen@e-ma.net]:
> * _we could make the ENV only be able to configure 1 level deep, and count the _ then we know if its part of component name or not_
> * _some magic word, like _DASH_ eg so you do AWS2_DASH_SQS_SECRET_TOKEN = 123_
> * _make a known list of component names via camel-catalog, and source code generate it into camel-main so it knows that AWS2_SQS is the component name_
