Ok, it seems to be a difficult problem to solve.
The idea of ZVols is to provide a generic block device, although most people 
would use it to store other filesystems or swap. The only way I could see it 
working was using the loop module. But I see how mountlo could probably work 
for filesystems.

Thanks.
