Description of problem:
Could be a udev problem or an selinux problem (though I don't see any selinux errors) but my eth1 device, a bcm43xx, now comes up as dev4679.

I believe this started with the kernel-2.6.15-1.1869_FC5 kernel, or at least that rawhide update, and continues with this kernel.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
Actual Results: The bcm43xx is no longer named eth1 but dev4679.
From the discussions I have seen, this sort of thing is unavoidable, at least
for softmac based devices. But I think that John is the final authority here.
Please use nameif(8) and /etc/mactab for now.
It's back to eth1 with kernel 1872 and beyond.
The problem is back with kernel-2.6.15-1.1907_FC5. Is the /etc/mactab going to
be the official solution on is this just a transient bug?
And fixed again with kernel-2.6.15-1.1909_FC5.
I think this is actually some sort of problem wih
your /etc/sysconfig/network-scripts/ifcfg-ethX files. My guess is that you
are specifying MAC addresses in some (but not all) of them, and the renaming
of the interfaces is getting confused.
Bill can answer this one without sweating... :-)
What do your ifcfg files look like?
I did have some old ifcfg files hanging around from when this problem first
occured. I had one made for dev4679 with a correct hw address in it so it was
probably the cause. After removing them, the 1907 kernel works normally.
