How would writing it as a FUSE fs add complexity, as compared to whatever (which we don&#x27;t know) they&#x27;ve done on Windows and OS X? FUSE is built for stuff like this. If anything, it should be easiest with FUSE.<p>And then they could have used the same codebase for Windows with Dokan (which has FUSE compatibility) and OSXFuse, although those two aren&#x27;t installed by default. (FUSE is).
