There are only two "roots" when dealing with GRUB. First, the system's
root directory, which is located on the root partition. Second, GRUB's
root device, specified with the "root" command in GRUB. Let's stick to
the terminology and not confuse "root directory", "root device" and
"GRUB's root device". GRUB's root device is not a root directory. On
GRUB's root device, the files usually are located at the root of the
partition's file-system, but that's neither mandatory nor relevant.

P.S. Concerning some of the off-topic msgs about Karl still opening
too many new threads for every tiny change in topic, yes, it's
tiresome. Simply adjust the "Subject" a little bit and keep the
messages in the old thread until the thread ends due to a period of
inactivity.
