With very hard work, I had finally released the version 2.0 internally, so now I had got a complete file system to support data center storage application. It's about 38M, live-cd, very easy to use.
I'm thinking next step, should I start from router or virtulization? If I start from router, it should be a bit easier, but I really want to make more contribution in virtulization as soon as possible. I need time to think about this.
