### What needs to get done If a project has `bare` base and either `overlay-script` or `overlay-packages`, we should fail as early as possible. ------ Ideally we should fail during project validation, but we would need a craft-parts-provided way of determining whether a project is using overlays (so that we don't keep all that logic in Rockcraft itself). ### Why it needs to get done The two features are essentially mutually exclusive: the overlays are a way to configure the base system, and the `bare` base is about not having a base system at all.
