    Umm.

    "userspace filesystem"?

    The problem is right there. Always has been. People who think that
    userspace filesystems are realistic for anything but toys are just
    misguided.

    fuse works fine if the thing being exported is some random low-use
    interface to a fundamentally slow device. But for something like your
    root filesystem? Nope. Not going to happen.

    So Andrew, I think that arguing that something _can_ be done with
    fuse, and thus _should_ be done with fuse is just ridiculous. That's
    like saying you should do a microkernel - it may sound nice on paper,
    but it's a damn stupid idea for people who care more about some idea
    than they care about reality.
