You can execute the bootstrap process.��
However, maybe that is not required, as the bootstrapped��images for Pharo7 are stored.��
These are the latest (always):
These are the first images that are usable, the first one has a compiler and the second adds the traits implementation.
As Esteban said, you can modify the process to bootstrap whatever you want. However, having an image that does not have compiler��it is more difficult to use.
If you define better what do you call a minimal image we can help you more.
