interrupted rpm transactions can cause pretty much any sub system to
stop working. Feel free to dive into rpm development and create a fix
for that problem.

I thought that was a separate problem (in a flurry in the FC2/FC3 era) but similar in dealing with RPM swapping incompatible db libs underneath itself. I recall for a while I defensively did a separate run of yum to just update rpm and yum to minimize the chances of failure or mismatches pulled from out-of-sync repos before starting a larger update. I don't think there have been many problems recently, but it will still be tricky to make the yum/python switch foolproof - especially if you don't permit multiple versions of python to exist at once.
