Garrick, I can appreciate not wanting to upgrade when things are stable. It's when things go wrong that trying to figure out what exactly is happening in your version of the code becomes difficult for us, since we have potentially moved far beyond where you are and may have difficulty putting together the pieces (working with vibrant and dynamic software is both a blessing and a curse at times!)
So, before you upgrade, one place to look: Do you have any postscripts set
for your nodes that might be trying to configure your network interfaces?
lsdef <nodes> -i postscripts,postbootscripts
These scripts are all stored in /install/postscripts, so you can grep
through them to see if anything is changing your ifcfg files.
Your "At long intervals, we are finding that the ifcfg-eth* are being
overwritten..." could be caused by running updatenode to the nodes for
other reasons, and a postscript reconfiguring your network interfaces is
running as a side affect.

Ah crap. I hate upgrading stuff that works fine.

Subject: [xcat-user] xCAT dhcpd overwrites ifcfg-eth* files?
I have an issue with a relatively new xCAT-maintained cluster of
redhat nodes.
We use xCAT and the associated DHCP functionality for system
provisioning and upgrades, but all of our nodes normally have static
IP addresses. At long intervals, we are finding that the ifcfg-eth*
are being overwritten, causing us to go in and add IPADDR and NETMASK
lines to ifcfg-eth* files that no longer have them, and restart the
network service. At the same time, for example, ifcfg-eth*.xcat
files are created.
I suspect that dhcp is doing this, but would like to confirm before I
try to remediate.
