@damm I don't know if it will fail on Windows. That was a question - "will the lvm gem compile on Windows?". Again, I'm still failing to see your argument as to the inclusion of all these kitchen drivers. "It doesn't hurt anything" isn't a strong enough argument, in my opinion, for keeping them around. If there's a real business use case for having them, then we should keep them. But like I said before, there's nothing stopping you from having these drivers installed locally and using them.
