in that case you will need to find the updates in the 5.1/os/ repo as 
well and put it yourself into the updates/ directory, which will be a 
waste of time, network bandwidth and resources. You are going to be much 
better off just installing 5.1 from the future and using that.

For the machines you have 5.0 on, just run yum against the 5.1/os/ and 
5.1/updates/ repo, and they will also move to 5.1. Note, the [os] repo 
also needs to be from 5.1 and not from 5.0 when you run the yum update 
on the 5.0 installed machines. other wise you *will* loose updates.

you are trying to solve the wrong problem. I suggest you take a few 
minutes and work out exactly how the /5/ and /4/ symbolic links are 
handled on the mirror.centos.org network, and setup something similar 
for yourself as well.

I dont know how you install the machines, but i think its a fair guess 
that just reimaging the install process with new installer images for 
each point release, will be a lot less work than what you are doing at 
the moment.
