Description: An overlay is a way to add additional software packages to a package management system without modifying the main repository. This feature is especially useful for users of various Linux distributions, as it allows them to access software that is not available in the official repository or specific versions of packages that may not be included in the main tree. Overlays are essentially repositories of software packages that can be managed independently, providing flexibility and customization in software installation. Users can create their own overlays or use those developed by the community. This allows developers and users to experiment with new software versions, patches, or specific configurations without affecting the stability of the base system. Additionally, overlays can be easily updated or removed, facilitating dependency management and conflict resolution between packages. In summary, overlays are a powerful tool for software management, allowing users to efficiently and safely customize their environment.
