The objective is not to cherry pick updates, but rather to install a second system with packages that match the first system.  After fine-tuning the installed packages and stripping out the unnecessary stuff, it would be nice to just say "make that system look like this one" -- rsync for yum if you will.  The specific package versions aren't important at that stage since I can run yum update after the initial installation.
