I think there is user space initialization required for lvm volumes - 
the config of the
volume has to be loaded into the kernel from user space. This is the way 
it was the
last time I heard Heinz talk, it may no longer be true. However if it is 
the case you
need a bootstrap mechanism to get the root lvm volume configured before 
you can
mount it.
