I just want to mention some theoretical benefits that could arise f= rom using a Guix-aware build-system. A Guix-aware build system could improve upon the traditional timestamp-base= d rebuilding heuristic by using a content address heursitic. This benefits = developers using the Guix-aware build system because it reduces the number = of rebuilds that occur and enables transparent artifact sharing when multip= le versions of a project are checked out to different locations. It benefit= s Guix itself because it enables incremental builds inside of Guix (includi= ng on the build server). A Guix-aware build system could remove overhead for package maintainers. If= the source repository contains the build code - which in proper Guix style= is deterministic and contain precise dependency information - the packager= only has to verify the source hash. This benefits packagers because they c= an focus on the social value provided by packaging (discoverability, pre-co= nfiguration) without worrying technical problems such as a library updated = for an otherwise unrelated package.
