GRUB passing DHCP discovered IP address to kernel

[Abraham Pearson]

Some time ago Paul Hedderly sent the following:
>I have a problem here.

>Anyway - is there an easy way to get GRUB to pass the

>I'm using:

My kernel gets a dhcp reply just fine, by I would
rather skip the duplication.  Has there been any
progress on this?  Will there?
