Yes, see my penultimate paragraph above.

It looks like the final fix is only in initscripts-8.45.7-1 (for FC6). 
Anything earlier might arbitrarily rename certain network devices on boot. 
I don't think it would necessarily change the *contents* of ifcfg-*, but 
would definitely change the *names*, so it might seem like the contents 
change.

Setting HWADDR might also be necessary, even with latest initscripts.  I 
always set that, so I haven't tested without it.
