  As far as I know, libzfs is not a publicly documented API.  I don't think I 
can give any assurances about its stability.

  My gut reaction to that would be that it would probably be easier for the 
ioctl interface to change than the libzfs interface, but that's my personal 
opinion :).

  If you do decide to make changes for other systems, it would be nice to leave 
in the libzfs code that exists for platforms that have it, if that's 
allowable/possible.
