Hi Sanjay,

A few questions...

For clarification, does this mean we only copy data from the root pool, 
or root pools if there are multiple(and allowed for multiple root 
pools)? The reason I ask is that the ZFS root filesystem, /, today does 
not have separate /var or /usr. I know that there is talk of allowing 
for a separate /var dataset, which means that this dataset could live in 
another zpool(not the root pool). So, is the plan to 'follow' any 
datasets that are part of the BE's? Even if it means spanning pools?

I have been thinking about this, and I am assuming you mean that we 
won't copy anything outside of what is defined in the BE's, which right 
now is anything under rpool/ROOT/. So, /export/home is in the shared 
dataset space and would not be copied? I am asking because what does 
this mean for zones that have datasets as resources that are not in the 
root pool? Or a device as a resource. It sounds as if there is a 
possibility that some zones configurations will not be fully functional 
or bootable on the new system if we are only copying the content of the 
BE's.

Requirements:

We should probably outline in more detail what the specific requirements 
for non-global zones is.

that's it for now.

thanks,
sarah
