Conary is a free software package management system created by rPath (now SAS) and distributed under the terms of the Apache License Version 2.0. It was relicensed from the GPLv3 in 2013.[2] It focuses on installing packages through automated dependency resolution against distributed online repositories, and providing a concise and easy-to-use Python-based description language to specify how to build a package. It is used by Foresight Linux and rPath Linux.

Conary updates only those specific files in packages which need to be updated; this behavior minimizes bandwidth and time requirements for updating software packages. Conary also features rollbacks[3][4] of package installation as well as derived packages.[5]

The Conary toolchain includes rmake, a build server for conary packages, which builds packages inside chroot environments containing only the package's explicitly listed build requirements and some other fundamental packages. This is very useful for packagers, because it means that package builds can be done inside a reproducible environment, and packagers cannot accidentally introduce dependencies on peculiarities of their machine's environment (such as custom configuration files, or undocumented extra packages).
