I finally tracked down why the keys of the #knownEnvironments Dictionary were changing when trying to build an image in Spur.
It's because, in my core-extensions package, I override UndefinedObject>>#hash to have hard-coded value independent of its #identityHash, to be safer with distributed systems which may be using nil in a hash calculation -- in case they would be different due to accessing with a Spur image, for example.
Such a hash calculation is made for the keys of the #knownEnvironments Dictionary when the country's are nil. By the different hash value in Spur, the image would lock when trying to load my core-extensions package, because it tried to access knownEnvironments as part of the load-operation itself.
The least-lazy way to "fix" it was to ensure something is populated in the LocaleID's 'country's. Whew!
Anyway, something to be aware of -- anywhere we have true, false or nil used in a hash calculation, now has a different hash in Spur vs. Cog. Maybe we should think about separating those objects' logical "value" hash from their identityHash in trunk..? That could be useful when we move to 64-bit someday..

OH! I saved this as simply System instead of System.spur. AND, I think I may have been in a Spur image when I did it.. (trying to remember) -- If I was, does that mean I accidently saved the Spur-version of System under the wrong branch?
When I update my Spur image, it is not pulling this in -- I guess because there is no .spur version of it?
Eliot this is my first trunk commit of a branched package from a Spur image do I need to save it again as .spur or actually you have a converter don't you? How / when does that get run?

Argh! You can check the history, but if you did this we need to delete the package asap. It will break non-Spur images.

What's your update URL?
Eliot this is my first trunk commit of a branched package from a Spur image do I need to save it again as .spur or actually you have a converter don't you? How / when does that get run?
I would prefer that yoiu integrate the changes into trunk and publish from trunk. That's because the process (until we release) is for me to autoedit trunk versions to produce the Spur versions. No, this isn't satisfactory but it works and will allow us to transition properly when we release.
I think I wrote this all up in an email a few weeks ago.

No worries, it looks fine to me.
