No automation at all is needed.

Again no automated tools.

I think you are getting hung up on the automated tools thing.  
Automation is nothing to do with this discussion.

I am not asking you or anyone to automate tools or anything.

I am asking you to use a process of thinking that documents what you  
do, in a way that enables it to be routinely harvestable. Its a  
process of knowledge capture. You can write it on paper if you like:

Example:

If you write me an explanation of how to install closures, it will be  
a lot easier to write if you say.... Start with a 3.10-release image.  
Do a,b,c,d,e and you will have a closures image, we shall call 3.10- 
closures.

As a trunk developer you cant write me this explanation. If you write  
me an explanation of how to install closures following trunk, it will  
be... Hmm when we did it we had this image that was hacked on by 10  
people, so this is how I did a,b,c,d,e but I cant be sure that this  
will work for you.

that is the difference, and my example from the bazaar documentation  
clearly shows the difference
