ksdevice=link seems to work for us when reinstalling SL5 systems with SL6. But maybe that's just because we have installed all systems with pci=bfsort since the SL4 times, making device numbering consistent across kernel versions (and we use only eth0 for PXE). Using pci=[no]bfsort, it should always be possible to make the interface in use primary one. But then I'm not sure what Networkmanager or the new parallel udev device discovery may be doing... And since 6.1, some (recent Dell) servers have biosdevname enabled by default. Which makes the first onboard interface "em1", for example :-) The advantage is that this will always match the physical socket labelled "1" on the server. > I can get to this system to test pretty easily, the systems I want to do this > on if I can fix this issue I can't.
