Steve,

You put your finger on it: "installed" doesn't help me much. The key
here is the number -- 2,759 packages. I've had four years to customize
the stock setup. The wisdom of my rule not to install anything that's
not packaged as an rpm becomes evident now. (Of course, there WERE a few
such as rpCalc and diskspan that I couldn't get along without.)

About 95% of those packages will probably come from the RHN repository.
Another 1% will come from Scientific Linux (the Open/LibreOffice stuff).
Maybe 2% will come from EPEL6. A tiny number will be the repo rpms
themselves.

I may be able to use your method to generate "before" and "after" lists,
then make a "diff" with maybe 50-75 packages. Some will be obsolete and
replaced. Some will be easy (e.g. crossover-pro.i386), but some I'll
have to remember going back almost four years. This game of "Where's
Waldo" could take a while.
