code: func (g *GLogger) Fatalln(args ...interface{}) {
  	// Teleport can be used as a library, prevent GRPC
  	// from crashing the process
  	g.Entry.Error(fmt.Sprintln(args...))
  }
docs: // Fatalln logs to ERROR log. Arguments are handled in the manner of fmt.Println.
  // gRPC ensures that all Fatal logs will exit with os.Exit(1).
  // Implementations may also call os.Exit() with a non-zero exit code.
