Ah. I see where I am confusing you. Sorry.
My *current* code is (literally):
# yum install $(boostrap_firmware)
What I *want* is a plugin that automatically does this, but I wanted to
run the idea past yum-devel first for feedback.

to do.

Nope, you arent missing anything. It was just very basic question.
Now... my next question is how do I do this? I need some example code or
docs to look at that give a good example. Can you point me in the right
direction?
