Sometimes confusions are wo/manmade ! ;-D

One says "user partition" which exactly isn't exactly as said under
Linux !! ;-)
"user's data" are in/under /home with the user's (login) ID !!! ;-))

Using the expression "user partition"
misinterpretations/misunderstandings with /usr ...
... and even related to user too, causes confusions !! ;-(

Using the correct expressions and nomenclatures is important and 
we should keep these precisely ! ;-D
