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.

Well if you're planning on doing a yum update anyway just cat rpmlist |
xargs yum -y install

Better solution to this though is a basic ansible task list defining what
you need.
