According to millward:
What's kudzu ? I've read the man mount but there's no kudzu there. What does it do?
It's a utility that runs at system startup to check your hardware configuration, and allow you to setup/configure any new or changed hardware.
If your system will be stable after you've set it up, you can always disable it as a startup service to speed things up a bit...
chkconfig kudzu off
However, I like to leave it on, so it catches any hardware changes I made, or anything that may "mysteriously" have changed.
