Curated Linux package repositories are all about making painful things slightly less painful, including: - Managing complex dependency graphs. There are often incompatible changes in the nodes of the dependency graph that require wholesale updating of every node linked to the changed one. - Managing complex installation. As per UNIX standards, the files which comprise a single software package are spread across the file system in such a way that it's effectively impossible to clean them up without a package manager properly tracking them. Apple's "curated package repository" is something else entirely.
