If you have a working init.d file to start/stop + filtron service, please contribute. + Filtron needs Go_ installed. If Go_ is preinstalled, filtron_ is simply installed by ``go get`` package management (see `filtron README`_). If you use filtron as middleware, a more isolated setup is recommended.
