It would make sense to be able to optionally start a PRServer with the controller when the autobuilder is configured for a single shared PRServer running on the controller, a setup we'd like to switch to on the project's autobuilder clusters. Currently we automatically start a shared local PRServer (with an up-to-date clone of bitbake) on each worker when PRSERV_HOST is set to localhost.
The builds no longer start individual PRServers and we have other nodes doing HashEquiv .
