Thanks all for answering (sorry for the multiple posts, I was tuning my 
mail server)

I believe that on a same freebsd there should be a consistent behavior 
among different
mounts. So in my opinion ZFS should conform to UFS (or UFS to ZFS, if 
that's desirable).

The best thing would be to have a sysctl tunable to choose that (sysv5 / 
bsd). BSD should
be default, since it makes more sense for workgroups...
