Configuration management systems (chef, puppet, cfe2/3) is a superset of package management#, which is, in turn, depends on frozen static artifacts of each project's build system.

# This is because configuration management installs files, packages, templates files and runs commands pre/post, similar to how most package managers work, but at a fine-grain level of user customized as opposed to maintainer customized.

The meta is that one could consider a "system" or approach by where the project build and configuration management systems were seamless. One main challenge in doing so would be that the staticness of artifacts allows for reproducible compatibility, whereas end-to-end configurability can easily become Gentoo.
