Description of Problem: Subject line says it all.
bashrc has moved to the setup package.
Hmmm... so you upgrade from your existing bash package to this one, and *poof*, your /etc/bashrc file is nuked. :(
Well, it should leave an .rpmsave behind if you have modified it I think.. Anyway, perhaps it would be best to Require setup package fresh enough.
anaconda handles this case for clean 7.1->7.2 updates
Someone might want to update bash, e.g. grab the latest from rawhide and rebuild it on older systems. Heck, it happened to me. Missing /etc/bashrc is annoying, and without Requires this can only be handled gracefully when using anaconda. But anaconda is not all.
