Which release of xCAT you are using? In the latest releases xCAT added the postscript 'confignics' to help configure the nics for compute node. It could fit your requirement to configure nics for stateless node. But confignics postscript only works in 2.8.3 to support stateless (implemented with bash) since the one which released before 2.8.3 was implementation with perl, but perl is not a default package which installed for stateless node.

So we utilize hardeths to turn the interface into a statically-assigned IP to prevent that.

Unfortunately genimage still seems to need this flag to produce the /etc/sysconfig/network-scripts/ifcfg-eth0 file. Hardeths needs this file to be able to correctly create a static interface file. Am I missing something there? I also found that the "nodebootif" option in osimage was what I was looking for to give me the missing "-i" flag. Thoughts? Is there a way to properly get the needed /etc/sysconfig/network-scripts/ifcfg-eth0 file into the image without using the "-i" flag? Or a way to get hardeths to cooperate when the ifcfg-eth0 file isn't there?

That means during the genimage, no specific interface needs be specified, but configure the mac address for node and set installnic=mac so that during the boot of stateless image, the interface which specified with the specific 'mac' will be used. So the problem was that did you configure your node correctly with the mac and installnic attributes I guess. If you really want to specify the network interface by yourself, just use the -i flag anyway.

As a result, the image that is generated is missing ifcfg-eth0 file, and hardeths fails on the node. Am I missing configuration somewhere that would give me the missing -i flag for my genimage line?
