Conary (package manager)
Encyclopedia
Conary is a free software
package management system
created by rPath
and distributed under the terms of the GNU General Public License Version 3. 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 Rollback
s of package installation as well as derived packages .
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).
