¥Just curious... did you try following the instructions at:
¥/usr/share/doc/packages/sysconfig/README.Persistent_Interface_Names
¥
¥Personally, I'd reset your local.rules back to the original and
¥follow the instructions mentioned above.

I have read the README docs, the man pages, and online documentation for UDEV. 

	The main issue is the fact that I have only remote access to servers in unknown locations. I'm remote imaging them to convert them from SCO to SUSE. The 3Com cards are the only NICS connected to the network. The company hard coded their software to use ONLY eth0 over a 3Com card. So, I have to figure out how to configure very many remote servers on initial imaging to make the 3Com card eth0 without fail. None of the servers are identical in any fashion except for using the same LINUX image and having a 3Com NIC.  The servers run the complete gamut of hardware configurations possible on a X86 based architecture. 

	Based on this information, I have been able to gather. All I know is that the images load correctly on the servers, but 20% of them do not define the 3Com NICS as eth0 no matter what is in the UDEV rule set. 30-net_persistent.rules is completely empty of all rules on the image. I have even deleted all defined NIC info in /etc/sysconfig except for IP configuration information on eth0. I have even accounted for the variance in SYSFS for reading the variables from the NICS differently depending on where they were made. That is why I have 3 lines in 10-local.rules.

Any other suggestions?
