Right. So hard? Its a lot of work that is unplesant and nobody wants to do, I think that qualifies as &quot;hard&quot;. I do agree its impractical, but it seems that for something as important as a function, working file system (and don&#x27;t suggest that butterface fs is a production ready alternative) that somebody would put in the work to make it happen. After all the file system is everything, if you can&#x27;t safely store your data, whats the point?
