 Support for a distribution implies all the duties covered by the Approver and Maintainer role requirements. In addition, support means that the Collector SIG is the owner and maintainer of the binaries/images of the different Collector distributions and is responsible for the pipeline that produces those artifacts.
 
-The Collector SIG will support at least one distribution that is recommended for production which includes support for Prometheus, Jaeger, Zipkin, and OpenCensus.
