maybe I am missing something important, but is this useful for anything
besides nfsboot?

If linuxname is a property of the device, how do we decide between
eth0.linuxname and eth1.linuxname when doing a "boot /mnt/nfs"? 
In this case we need additionally a global variable like nfsboot-
device=eth0 to switch between nfsboot devices and to make the decision
when filling the ip parameter?

Best regards
