+For each toolchain the \c{bbot} agent polls one or more controllers for build
+tasks to perform. The controller URLs are configured with the
+the \c{buildos.controller_url[.<name>]} kernel command line parameter (where
+\c{<name>} is optional toolchain name). To specify multiple controllers,

+command line parameter to specify SHA256 repository certificate fingerprints

+multiple fingerprints, repeat this parameter.
