What OS are you running on?
I don't know if this helps, but, at least on Mac OS X, my image build
script from Cog works to the extent that only Environments and Monticello
are marked dirty. Note that Monticello is not actually dirty, and
Environments is dirty because it has two ancestors, nice.47 & cmm.51 (as
you report below). You can find the script here:
BuildSqueakTrunkImage.st - the update script
buildspurtrunkimage.sh - the script that
downloads Squeak-4.5-All-in-One, updates it to trunk, builds a VMMaker
image, and uses that to convert the trunk image to Spur
"Change the update stream to trunk and update"
updateFromServer] valueSupplyingAnswer: true.
Smalltalk snapshot: true andQuit: true
The script has been tested on Mac and Linux. The update process starts
with an empty package cache.
I identified all corrupt versions, cleared the package-cache and preloaded
