Introduction

In case any of the source files changed, openSUSE Build Service rebuilds the dependent packages regardless of whether that particular modification affects the dependency. This makes our resources footprint bigger (and the electrical power bills higher). It also affects users, because every new package build causes the package manager to include that package in the next update thus consuming network bandwidth and resources of users' computers.

www.opensuse.org is the single most accessed page in the SUSE/openSUSE universe. With 1.5 million visits per month it generates 2.5 million page views and has around 500 people on the page at any given time. Yet it's one of the oldest, crufty pages we have!
