As development of SwOS (Lite) seems very slow - MT, please consider releasing this code as open source. Then the community may be able to help fix the longstanding bugs, and MT still makes money on the hardware. Why not?
On devices that support both ROS and SwOS, I prefer ROS anyway, it's much more powerful, and I wish it was possible on all switches. Adding a better CPU with some RAM shouldn't cost that much, the cheap CPU from RB931-2nD would be good enough as it's just for management. But for some devices (such as CSS610 series) there is currently no such choice, they are SwOS only. This is where the open source SwOS firmware would help the most.
