There is absolutely no meat in that article. We have no idea about the technical details of what Microsoft has done. All we have is the aspirational witterings of a couple of seasoned industry bloggers. There is no use comparing vague Windows rumours of a not even released product with what Linux has been able to do since its inception. And BaseFS sounds like VFS, the virtual filesystem layer in Linux also - you'd think it was the most novel idea to abstract away common functionality to a shared core, this design pattern is as old as the hills. These pieces of news carry next to no information, it's pointless that this got onto the front page of HN.
