Without proper Obsoletes/Provides in both directions (i.e. Fedora <-> 3rd party repo), it doesn't work flawlessly. libbar3-3.0.1 will conflict with libbar-3.0.2. AFAIK, this has happened several times before. Additionally, you need to take precautions and relocate files in several packages for them to become parallel-installable. > This will even help Fedora, as the reason Debian/Mandriva introduced > them was for being able to cope with tons of packages when a > dependency does an sobump. Without a doubt. If done properly, it would fix the poor broken deps caused by sudden/unexpected soname bumps. > Currently in Fedora whenever a package with many dependent other > packages changes soname, we need to go yelling around to other > packagers and are only able to do an upgrade of this kind in rawhide. This is also due to koji buildroot protection and overrides. Some packagers believe they must push a soname bump to stable before they can rebuild dependencies. They feel embarrassed when they learn that they can request releng to set an override-tag and then prepare a group update for bodhi.
