If everyone is running STANDARD CENTOS there should be *no* problems
updating to the latest C 6.8 version.

(1) Save one complete installation.

(2) Install it on a spare machine.

(3) Change /etc/sysconfig/network-scripts/ifcfg-eth0 if necessary.

(4) Do a: yum update

(5) Test the applications

(6) Wait a few weeks and if still no problems, then upgrade the others.
