[Freeswitch-dev] choosing the right place for smartos specifics

I'm going to add a few scripts which automate the build under SmartOS, and also the SMF manifest which launches the service. Where is it the best to place within the source tree? Probably build/smartos ? or simply /smartos from the top hierarchy? Or maybe a new "os" folder, and "os/smartos" under it, so that we have room for other OS'es? Debian is an exception, but it's a default OS anyway.
