That's an interesting approach. It's too bad linux can't already run any in-kernel filesystem as a user process via FUSE, when you prefer greater isolation in exchange for worse performance, at the flip of a mount option. There's no technical reason for this to not be possible IMO... it's just a product of the tight coupling of everything in-kernel, as implemented today. I'm short on time to confirm at the moment, but I believe it was this [0] talk that left me with the impression kernel devs were exploring general solutions of this nature.
