Sorry for the delay in getting back to you on this. I got pulled into a high 
priority issue. This patch looks more complex but safer than what I proposed. I 
patched against grub2.02~beta2. Hunk #1 appears obsolete. The rest applied 
cleanly, but the network came up completely unconfigured. 
(net_default_ip=(null) net_default_mac=(null) net_default_server= ) I will poke 
at the changes and see if I can figure out where it went sideways.
