Hi,

Actually you have also missed the effort that I have been working on  
to create an update.sh which is included directly into core. see http://drupal.org/node/233091 
  which has a working version of update.php but runs from the shell.

I have also have some more changes pending that Dries has suggested.  
but before I can do these I have 2 other patches which are really  
needed for the update.sh to work before I can really push forward.

http://drupal.org/node/375494 which is a patch to change node_load()  
to restrict the size of the static cache and http://drupal.org/node/383196 
  which is tests for update.php so that when I break update.php to  
create a better merged update process to share as much code between  
update.php and update.sh.

It is not a coupled as you think. other than the fixes, most of the  
update.php/update.sh is all done in the batchapi. before the batch api  
it was not as clean as it is now.

I do have to question about how many ways do you need to do updates.  
This is why I have been pushing a shell version as this can be  
interfaced into anything that can run updates.

I am actually looking at moving most of the update.php stuff to  
update.inc, but other than the fixes which as used to allow the newer  
version to load on the previous versions database, there is not really  
that much that can needs to be  pulled out.

If you want to talk more, just grab me in IRC, or update the update.sh  
issue.

Gordon.
