loading fresh system from rpm list?

[Steven A. DuChene]

The original system is a VERY minimal install and that is what
the owner wants me to mimic on the second system. He very carefully
went through and removed any packages he did not absolutely need
so rather than duplicate that work I thought I could somehow just
work from his list of rpms on the original system.
