content: It's only ubuntu base (just a minimal install with some development tools on top). It is not quite clear how it is implemen  1351  ted because of conflicting information from what was seen in a developer blog and the first announcement that was made. They obviously have a module that translates Linux kernel syscalls to Winnt kernel syscalls. The official blog states that they are using UML (User Mode Linux). I'd be tempted to look at it, but the EULA does not allow for that and I don't want to infect another machine with Windows. I do find it interesting though.
