Main goals
- Update metadata for installed packages to take/withdraw ownership for new/updated files or registering additional metadata.
- Reduced responsibility to allow more freedom. For example resolver might be quiet complicated and just produce install/upgrade/remove scenario.
- Suitable for manual recovery on a partially corrupted system. I.e. it should be as simple as unpacking archive in filesystem, but still preserve consistency of metadata.
- Managed collisions with manual control of safety during install/remove:
- no-conflicts: only install packages with no conflicting files.
- allow-identical: keep files of same content and avoid removing referenced files.
- yield: create new files with slightly different names and intended to be merged into existing files by other tools.
- clobber: simply overwrite old files and remove only own content.
- Support many-to-many package replacing.
- Maintain proper metadata describing installed packages.
Metadata format
It is expected to be used in Exherbo and thus it should be exndbam/vdb compatible format. It is expected that other tools may want associate with packages additional information and provide more advanced indexes. More to define
Install sources
Image of root folder with additional information like name and optional version. More to define
