Yea, that's a good point. There's a fine line and we really need precise
specs so you and the FreeBSD guys can implement this. Really, if the
spec is unclear it should be clarified (patches to the spec!) and I
think it's possible; all the Linux specific bits have been clearly
namespaced to identify that though there is some reliance on POSIX-y
bits like block devices etc.
