<<< I would prefer to upload a MetacelloConfiguration (or something similar) instead of an image. I like to think about the image as a temporary runtime. Not something where I store code or someting I deploy. I would love to have something like: $ pharo -v 1.4-summer myProject.ston where myProject.ston would contain all the necessary information to load my project (dependencies, repositories, etc). This command would create an image with my project on the fly from a stock Pharo 1.4-summer and launch it. It would recreate the image everytime I want to work on my project (or when it is deployed). The problem right now is the loading time for dependencies (try to load seaside in a pristine image, you'll get the point). All the other bricks are there.>>> Sounds like a very good idea. Does anything like that exist already? Also, it raises the question of what should be in the base image. Cheers Andy
