*the* root is more a concept of where something is at a particular time 
as viewed by a particular process, not what it is.  At some point in the 
boot sequence the kernel will see an initrd (ramdisk) image as *the* 
root, later it will be the partition grub said to mount as root, neither 
of which may be what grub itself considered as its root during an 
earlier stage of booting.  Later some process may chroot() and see yet 
another thing as root.   Or you may reboot, selecting a different grub 
entry that tells the kernel to mount a different partition at it's root 
location.
