That problem has been long dealt with. Use HWADDR in ifcfg-* to statically bind physical interfaces.
Tried that. Didnt work.
are you saying that specifying the hwaddr still got you wrong device name allocations ? I find that quite hard to believe, unless you are doing some wierd bridging stuff and the nic's are not really using physical devices.
It was 1 year since it was installed so I dont remember exactly. But I have done some investigation and I GUESS that I didnt had HWADDR in ifcfg-* because of the dates of them:
-rw-r--r-- 1 root 109 Aug 9 2008 ifcfg-eth1 -rw-r--r-- 1 root 109 Aug 9 2008 ifcfg-eth2
The box was installed Aug 9 2008. I can not be sure however, they might have been there first and then removed.
I didnt play with any udev rules during the troubleshooting. What I did was playing around with hal and the file /etc/sysconfig/hwconf. I changed so it would be correct in it (there I filled in the right HWADDR) and hal changed it back after reboot. The fucker. So now hald is totally disabled on this box.
I didnt know about ifrename to be honest (http://bugs.centos.org/view.php?id=3822).
However, I still think this is a BAD DESIGN CHOICE and Im not changing that option no matter how it can be "fixed" with udev, ifrename or HWADDR in ifcfg-*. That wouldnt be needed if you would wait until ALL cards are detected and THEN name them.
I just wanted to say this, as my current workaround about this problem works I will not change it or tweak it (it needs to be working, or else I dont have any internet... or exists on internet).
Thats about it.
a bit more info about your setup would be good. on a usual machine, with usual nic's - I've never heard of hwaddr allocations going walkabout. ever.
