Using static MAC's within a system creates config conflicts when adapters are exchanged that have different PCI-ID and drivers. Often the reconfigured machine will not boot (because of modprobe entries ) or network (ifcfg-ethX ) bring up fails because of stale configuration data left behind by the s-c-n tools. I am seeking to understand how make a more dynamic ETHERNET configuration manager (and underlying components) that bonds PCI-IDs and drivers to a ETHERNET device better than they currently do. When I remove/replace an adapter with a different one I want to invoke udev to clean up stale ethX and modprobe references. For instance .. how does /etc/udev/rules.d/60-net.rules get invoked ? My impression now is a driver of the "net" class has to post a message to udev to get processed by udevd, which rules a script/program. Is that correct ? > confused, Mine comes and goes. -- To unsubscribe from this list: send the line "unsubscribe linux-hotplug" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
