I hope you don't cry now, but I'm not using any bootloader :) I really 
can't see the use for it. Actually I have *two* kernels now, but the 
only thing my users see is an linux-2.6 as kernel in their config.

Oh they are doing:

kernel initrd-hey-here-are-the-iscsi-tools-lets-switch-rootfs

Instead the nfsway:

kernel-lets-find-a-nice-iscsi-machine


Not only the best way, the only way you can *safely* hide your storage 
from the domU's.
