Open Build Service? Open Build Service (OBS) is an open source project initiated by SUSE to create a generic build system to build and distribute packages from sources in an automatic, consistent and reproducible way.

How OBS works
Project and Package ● Project – Each project contains the resources needed to build one or more packages. – These resources include source archives, patch files, spec files, etc. – The project defines the build architectures and the general settings. ● Package – The packages are the build targets of the project. – The package format could be any supported output format, e.g. RPM or DEB.
Frontend – Web UI

Real-life case: openSUSE
Current Release ● All packages are in the release project and the update project, e.g. openSUSE:12.1 and openSUSE:12.1:Update. ● Each package update must be reviewed by the maintenance team and then be submitted to the update project. ● In general, every update has to be tracked by a bugzilla entry.

Next Release ● The packages for the next release are in the “factory” project, e.g. openSUSE:Factory. ● All developments are happened in the “devel” projects. ● The package updates are reviewed by the devel project maintainers. ● Any modification is allowed as long as the maintainer agrees.
