Building a new image goes like this $ ./vm.sh Pharo.image save test $ ./vm.sh test.image config http://mc.stfx.eu/XXX ConfigurationOfBetaNineT3 --install=bleedingEdge --username=XXX --password=XXX The Pharo.image is 'empty' as far as your own code is concerned, the config loads lots of dependencies. A build takes 10 minutes or so. But the next time, you can do only the second part $ ./vm.sh test.image config http://mc.stfx.eu/XXX ConfigurationOfBetaNineT3 --install=bleedingEdge --username=XXX --password=XXX The test.image contains all your project specific code, and loading the config just checks all dependencies and only loads what has changed, incrementally. It only takes some 10s of seconds. It never occurred to me that this was the way to go, but the config handler does it by default. Maybe it is just me, but I had the impression that everybody (including CIs) always built from scratch (more or less, there were staged systems), while it is actually quite practical to keep on updating the same image for a much faster turn around.
