loading fresh system from rpm list?

[Steven A. DuChene]

I have been requested to load a duplicate system based on the
list of rpms present on the original system. This is a CentOS
based system so I looked at the kickstart file but rather than
working with a list of rpms it uses a list of higher level
packages that then reference groups of rpms to make up each
package.

Does anyone know of a tool that would allow me to do a fresh
load of a bare system based on a list of desired rpms?

I have used systemimager in the past to pull an exact image
of a system for cloning but this idea has been shot down
by the person who requested this.

Any other tools out there that would do this?
