hmm, my disks are attched to a pci controller card because the mobo sata ports 
don't support the newer sataIII disk, the card bios reports the boot drive as 
drive 0 and if i swap the disks over then i don't even see the grub menu, 
reading about dracut i find:
Therefore, instead of scripts hard-coded to do various things, we depend on 
udev to create device nodes for us and then when we have the rootfs's device 
node, we mount and carry on. 
this seems to be the problem, upon booting and selectng the grub entry i get 
the usual on screen messages if i press esc. to get a verbose boot, all the 
way until a message about the root filesystem, a message about udev and then 
the message about not starting boot splash, 

i shall try to force a new imge using dracut
