The gist is the original yc debut of Dropbox had a comment that described a pretty technical way to get the same functionality as drop box. It's commonly referenced when folks on hackernews dismiss a product when they can do the same with 10 unix commands, not realizing they might not be the target customer. Interestingly I think this situation is the exact opposite, Kvass seems to be more complicated for a non technical user than file systems as the top level comment responded with.
