Learn About PackageGrid
PackageGrid will be a meta-package-manager, allowing for the management of packages and collections of packages across networks of systems. This will include tracking state across systems with the same package sets installed, and more.
PackageGrid is intended to make managing large networks of systems with the same, or similar, package sets much easier.
PackageGrid is currently under active development. It is open-sourced under a BSD-style license, and will be available very soon. It is in its early stages of development at the moment.
