Is there a script available for upgrade from 4 to 5?
I have tried it on one TEST computer following what I thought were the 
instructions and
after the update I still had 2.6.9 kernel not the 2.6.18. I looked in 
grub.conf and there were no 2.6.18 kernels.

Just wonder if someone has automated this process?
