That's today.  What about next week or next month?  As Zhenhua develops 
the revised Yocto layer strategy, I ask that he clarifies the policy on 
how the same named tree on different servers will be maintained.

Can we get a statement in the Yocto layers reorg doc on how each SDK 
branch will be maintained between SDK releases?  As a developer working 
to get products out the door, will I view the patched SDK branch 
(between releases) as a bug fixed SDK or as an experimental branch for 
the next SDK release?
