How to set up ZEVO / ZFS on an internal disk while maintaining full disk encryption? It seems that it's currently impossible to have the entire boot drive converted to ZFS.

How would one go about converting a single disk HFS+ Filevault 2 setup into a setup which has full encryption and most of the advantages of ZFS?

I imagine that there will have to remain a boot partition which is HFS+ and all user data would have to somehow live on an encrypted ZFS partition that will get auto-mounted and perhaps symlinked to /Users ... 

I'm on 10.8.3 and with CE Zevo (1.1)
Short answer … two Core Storage logical volumes, both encrypted: 


one LV, HFS Plus
the other LV, give to ZEVO. 


You'll need ZEVO Community Edition 1.1.1 (1.1 is outdated). 

In the answer to the linked question there's a note about Mountain Lion; OS X 10.8.5 makes things a little more difficult.
