As much as I like this concept, I don't really think the kernel
community is going to even consider all that stuff being integrated into
the kernel tree... at least not right off the bat.

I could be wrong about that, though, especially if someone other than me
drives the issue. It would definitely have to be configurable, though.

As does "proper" NFSv3 (you can do NFSv3 over secure RPC, although very
few people do.) That doesn't mean we have to support nfsroot over every
