ZFS as / filesystem on 7.0 ?

[Forrest Aldrich]

I recently updated my existing 6.x systems to 7.0.  Excited to see ZFS 
support, after looking through the current documentation, it doesn't 
appear we can use ZFS as the / filesystem, or am I mistaken (or is that 
even advisable).   The sysinstall doesn't seem to provide you with the 
option for ZFS on the newly created partitions.  So I could have / as 
UFS2 and /usr (et al) as ZFS.

Could someone clarify?  Perhaps I missed something in the documentation.


Thanks.
