- don't import eval-cache and flags modules by default (those have never been used so far)
- mark options of package-func as internal. Those are for maintainers only and don't need to be rendered by default
This is to improve package location finding at eval time and script execution time.
Deprecates options lock.{repoRoot,lockFileRel} as well as option eval-cache.{repoRoot, cacheFileRel}
Instead the user must now set:
- paths.projectRoot: pointing to the repoRoot
- paths.package: pointing to the package directory
- paths.projectRootFile can be used to define a marker file to find the project root. The default is '.git' but it could be set to 'flake.nix' for example
- lock files are by default put in the same directory as the package definition
