Thanks. […]

What are you doing? My concern was that there is already a message being printed (by the VTY code), but it does not say *what exactly is wrong*. It might not be obvious to the user/operator that only Ericsson RBS is supported, so we should make this clear in the logging message. See below: "Could not create unix socket", "Could not register listen"...
