Hello
I did a retest with the most recent trunk image
The image Squeak 4.2alpha #10437 - 17.5MB
SmalltalkImage current unloadAllKnownPackages
The image got down to 10.3MB
Further up in this thread Levente writes: Hm, I think Casey forgot to do [Smalltalk cleanUp: false] before saving the image. Doing that saves 2.8MB.
I did Smalltalk cleanUp: false but I only got 10.1MB
Smalltalk cleanUp: true brought it down to 10.0MB
It opens fine with a Windows Cog VM from http://www.mirandabanda.org/files/Cog/VM/ (I have not done any further testing yet).
As a whole I am pleased with the result.
So to summarize - a reduced image like the one I got with this process should take trunk updates properly in most cases?
