post-install: Fixed overrides in prepare-image
The overrides in the prepare-image weren't completely ported to the new syntax. Also the machine overrides haven't been changed to the new syntax.
Dear all, On Thursday, 4th September 2025, we will test the new disaster recovery environment. A disaster recovery test will take place between 4:00 PM and 6:00 PM CEST. Please refrain from making any changes, as they will be lost. Once testing is complete, the production environment will be restored. Thank you for your understanding.
