Interesting. I have different hardware, but use the macchanger module to change my MAC at every eth0 up, and don't have the problem here. udev must see the original MAC address on my hardware before macchanger gets to it, and thus set it up correctly. But if it's rewritten @ shutdown, why wouldn't it see the macchanger-randomized one then and thus get it wrong? So... three suggestions. One, see if emerging macchanger and configuring it will cure the problem. Maybe the system expects it if maccchanger is used thus explaining why it works with it here and providing a way to make it work there? Two, consider tweaking the related variables (RC_HOTPLUG, RC_COLDPLUG, RC_PLUG_SERVICES) in /etc/conf.d/rc, and see if you can udev to play nicely that way. (Here, I have RC_PLUG_SERVICES="! nt.eth0", allowing me better control of when it goes up, but it generally works without that, I just like and occasionally need the additional control.) Three, you may have to put a manual mknode somewhere in your scripts. -- Duncan - List replies preferred. No HTML msgs.
