Hello, Could you please explain a few theoretical questions: a. What's the meaning/usage of the "Super Root Block"? b. in the Readme (v2) file it's described as "an optional super root block (SR)". So as optional element, who chooses to whether to activate\use it or not? Thanks a lot. this is a very interesting file system.
