How do I supply a configuration file, if it is the nfsroot that is not 
being mounted? Maybe if one would try to put the udev-config into the 
initrd. Hm. Didn't think of this before. Need some glue beforehand though.

- boot initrd
- initrd starts a script which detects mac-addresses, tries to figure 
out the correct one and
   writes an udev/ifrename rule
  (which is kinda easy - we assign these macs manually - last three 
bytes correspond to the
   last three octets from the ip address)
- udev starts and hopefully assigns the correct interface
- fetch nfsroot

Big question: Is udev started from the initrd or from the nfsroot? 
Haven't looked to close into the initrd yet, maybe someone can tell 
without looking. I guess the later's the case. Then I'd have to rebuild 
the initrd. .oO(Is it worth the trouble?)

Wouldn't help the OP though. Since he's using physical nics, guessing 
the correct interface is a lot harder. Maybe by keeping a list of 
"valid" macs. But this means rebuilding the initrd each time a new 
machine is added. *yuck*
