You might as well be interested in GNU Guix
a package manager for the GNU system.

It allows you to install pre-built packages, or just download the source
and build locally with separable build environments.
  "Finally, Guix takes a purely functional approach to package
  management, as described in the introduction (see Introduction). Each
  /gnu/store package directory name contains a hash of all the inputs
  that were used to build that packageâcompiler, libraries, build
  scripts, etc. This direct correspondence allows users to make sure a
  given package installation matches the current state of their
  distribution. It also helps maximize build reproducibility: thanks to
  the isolated build environments that are used, a given build is likely
  to yield bit-identical files when performed on different machines (see

  This foundation allows Guix to support transparent binary/source
  deployment. When a pre-built binary for a /gnu/store item is available
  from an external sourceâa substitute, Guix just downloads it and
  unpacks it; otherwise, it builds the package from source, locally (see

  "Today, each individualâs control over their own computing is at the
  mercy of institutions, corporations, and groups with enough power and
  determination to subvert the computing infrastructure and exploit its
  weaknesses. While using hydra.gnu.org substitutes can be convenient,
  we encourage users to also build on their own, or even run their own
  build farm, such that hydra.gnu.org is less of an interesting target.

  Guix has the foundations to maximize build reproducibility (see
  Features). In most cases, independent builds of a given package or
  derivation should yield bit-identical results. Thus, through a diverse
  set of independent package builds, we can strengthen the integrity of
  our systems.

  In the future, we want Guix to have support to publish and retrieve
  binaries to/from other users, in a peer-to-peer fashion. If you would
  like to discuss this project, join us on guix-devel@xxxxxxxx"

An interesting talk on Guix was given this August at GNU Hacker's
