A user can already create a device with fuse implicitly. This patch would just allow that explicitly. Take this example: I've loopback mounted an UML disk image using fuse (no privileges required), and want to create some device nodes. I can't yet boot the UML because the device node is missing from the image. So what should I do. Currently I have to manipulate the mounted image as root. But that's really shouldn't be needed. > And no, I don't want to see a filesystem that implements it's own > file operations for device nodes. I don't want that either, and it has nothing to do with this patch.
