Open Stack

This is, indeed, the crux of the matter. The release cycle, for both 
diablo and essex, has been that all kinds of incompatible changes are 
made right until
the end. During the critical month before release when we need as many  
people ad possible to deploy and test real clusters, documentation is 
not available. Devstack was a huge step forward in essex because it 
allowed people who already understood the differences between single and 
multi-node to understand and cope with the incompatible changes to the 
components in a way that was known (mostly) to be working. I would guess 
that for every person brave enough to publish their struggles on this 
list, there are many more who do not. The only ways I know to deal with 
this are:

1. More stability. Fewer incompatible changes. This will come over time.
2. Require blueprints, tagged as such, for every API and configuration 
change. Maintain a highly visible list.

The other is longer release cycles with longer freeze periods but that 
is not going to happen.
