Jon,Have you ever tested the "obsoletes:" feature of setup/libsolv? I tried adding an "obsoletes:" line to setup.ini, and it didn't seem to have any effect.
It turns out that it *is* working (after a minor fix, attached), but not always as I expect. Suppose A requires B and C obsoletes B. Then the "obsoletes" statement appears to have no effect. If I remove the dependence of A on B, then setup does propose uninstalling B and installing C.
I guess the issue is that libsolv interprets "C obsoletes B" as "uninstall B and install C", and it won't uninstall B while something requires it.
