> Microsoft and GitHub are also working to bring similar capabilities to other platforms, with macOS coming first, and later Linux. The obvious way to do this on both systems is to use FUSE, an infrastructure for building file systems that run in user mode rather than kernel mode (desirable because user-mode development is easier and safer than kernel mode). However, the companies have discovered that FUSE isn't fast enough for this—a lesson Dropbox also learned when developing a similar capability, Project Infinite. Currently, the companies believe that tapping into a macOS extensibility mechanism called Kauth (or KAuth) will be the best way forward. I'd love to read more technical details on this. How can Kauth support a virtual filesystem?
