That would be great, but I don't know how to. Will look at it later.

I compiled kernel with smsc mac address patch because pandaboard choose 
random address on every boot. But you are free to use any kernel rpm 
which best suite your needs.

This is my config and I added it for example. There is also reference 
dracut page. Main thing is to add root=dhcp to tell dracut where to find 
root and smsc95xx.macaddr to set pandaboard mac address. But you should 
really see dracut reference page.

As above I added my config for example.


About grubby and flash-kernel.
I reworked ubuntu's flash-kernel to fit fedora and patched grubby so 
flash-kernel is executed by install-kernel script in grubby on every 
kernel update if you set UPDATEDEFAULT=yes in /etc/sysconfig/kernel.

flash-kernel utility is used to create uboot boot script and copy 
kernel/initrd to uboot boot partition. You could invoke it with 
flash-kernel $(uname -r) to just copy kernel or flash-kernel 
--update-bootscript to create new bootscript based on 
/etc/sysconfig/uboot parametars. It work perfeclty for pandaboard 
(omap4) but it have support for many platforms. It would be great if 
someone test it on other platforms.

I also filled bug for grubby #715460.
