I have an idea about combining ZFS COW/clone/snapshot natural and SANboot. The ZVOL target should not be created until we hit the menu.
This is my prototype demo and code:

Cool concept! Could you share your configuration and information on how you did this? Especially the backend scripts dealing with setting up the zfs volumes?
also i thought it would be good to mention, his code is linked to in his youtube :-)
My code :

I am moving the code to Nexenta Plugin
I don't know the Jentu's file system.
But using ZFS will save the RAM usage of a clone image.
Every clone of image share the same ARC cache.
If you clone 100 copies of a 40G image, it just take one copy of RAM.
