Many people put zones on ZFS file systems. If you want to put zone roots 
on ZFS file systems, you will benefit from understanding the current 
limitations. Sun has not stated that zones on ZFS are not supported.

However, in S10 U6 this situation will be improved, removing some 
limitations and reducing others.

Yes, that one clearly states that you can put zones on ZFS as long as 
you understand the implications. Although it's not a Sun Microsystems 
document, it's written by Sun employees, and in this case correctly 
represents Sun's stance on the topic.
