edit yum config file

[Derick Centeno]

Hi Paul:
The answer to your question is yes.  Yum can indeed search through  
several mirrors at the same time.  So if the yum.conf is written  
correctly and hopefully my explanation is clear enough, then it is  
possible to enjoy the benefit of letting yum do it's thing and you can  
sit back and relax.  The awesome thing for me is that by utilizing yum  
this way it allows yum to maximize or approach it's potential as a  
program and the computer can approach it's usefulness as a tool doing  
in seconds or minutes (if you have broadband or something faster) what  
otherwise would drive a human being nuts.

I may add more urls in the future to yum.conf; I submitted these just  
to be an example that others can be added and discuss as clearly as  
possible just how to do that.
Also this method of examining the mirrors first allows you to determine  
whether the servers are actually up and ready first before you write or  
modify your yum.conf in the first place.  The servers you choose may go  
down or change in the future but then you can comment it out.

By the way, just as an fun exercise there is an error in one of the  
lines commented out.  Can you identify the error, determine why that  
error will cause problems and that would be?

Ok, that's three questions presented as one.  Still, this kind of error  
happens all the time.  Learn it now and you'll pick up others getting  
in your way later.

As for tolerant and the others, you are probably aware that they are  
acting as variables for which it is defined for yum that it may  
investigate those categories exactly just one time.
As to why specifically they exist, I'll have to do a bit more research  
and get back to you.  They could of course be commented out, but the  
speed savings could be negligible.

Best wishes....
