An Analysis of RPM Validation Drift
John M. Hart, Jeffrey D'Amelia · 2002
Experiments that analyze dependencies in RedHat Linux and RpmFind.net show disturbing conflicts and overlaps between software packages that result in installing multiple differing versions of dynamic libraries. The final state of a system containing conflicting packages depends upon the order in which packages are installed, as well as user input during the installation process. This leads to system states that may or may not have been tested, lowering confidence that the resulting software configuration will function properly. We describe the details of the problem, potential effects, and potential solutions involving improving the practice of building RPM packages.
