Nice to hear you are continuing.
I'm not very knowledgable on this, but I'll show you how to pull some
data from the work on producing a minimal image.

1. From PharoLauncher > Templates > Pharo 6.0(beta)
�� �� download/create an image of build "60334-minimal".
2. Right-click on the image and choose [Copy pathname]
3. In a shell, change to that directory, and execute the following
�� �� $ ../../VMs/spur/pharo 60334-minimal.image eval "Object allSubclasses size"
�� �� �� �� ==> 2801
�� �� $ ../../VMs/spur/pharo 60334-minimal.image eval "Object class
allSubclasses size"
�� �� �� �� ==> 1399.
�� �� $ ../../VMs/spur/pharo 60334-minimal.image eval "Object class
printHierarchy" > /tmp/60334-minimal-class-hierarchy.txt

I've attached the output of that last one.

4. For comparison, in a standard 60334 image,
�� �� Object allSubclasses size "==>11923".
�� �� Object class allSubclasses size "==>5959".

Now in Pharo 6, the minimal image starts with a standard image and
strips these things out...
https://ci.inria.fr/pharo/job/Pharo-6.0-Update-Step-3.2-Minimal/ws/output.txt

In Pharo 7, there will be a new build system that it will start with a
minimal image and build it up to a normal image.�� So this may provide
a better way to understand the order that things need to be
implemented.
