I'm taking this idea from my university computer labs. There are 30 - 40 machines in one lab, each auto mounting the /usr/local directory. Programs like matlab, firefox, mathematica, etc are all in /usr/local/bin, and I'm assuming the libaries and other stuff need to make them run are somewhere in /usr/local/*. So, the sys admin only has to worry about installing or updating apps on the one machine hosting /usr/local rather than all 40 machines. That is my goal, but on a much smaller scale, one master computer, and two satellite computers. This is mainly a learning exercise that I hope someday I can implement easily.
So far I've figured out that yum and rpm are not the tools for my goal. I don't have much experience in installing programs form scource, but it looks like that is where I need to be looking. As far as it being too complicated to bother, I don't buy that. I have a simple goal, be able to install a program into any directory I want. That can't be very hard to accomplish.
Thanks for all the advice you people have given me. If anyone can give me advice on how to accomplish my goal with out using yum or rpm, I like to hear it.
Thanks,
Curt

bits that are installed locally, which also means you don't need actually need
a self-contained mini-OS.yum is useless here because it is designed for an entirely different purpose.

You could, in theory, rebuild srpms with "--define '_prefix /usr/local'", but I
wouldn't hazard a guess on the actual long-term success of that direction.Down that road lies madness. It is a tangled mess of evil LD_LIBRARY_PATH vars

and goofy scripts.
