In Linux, directories can be used as "mount-points" that look like
normal folders but represent a different filesystem on another partition
or even on another hard drive (Windows also has this for NTFS, but it is
hidden somewhere in the Volume Manager).
For example if you connect a USB Stick to your computer that has only
one partition it might get the device name /dev/sdc1. You could mount
that device in a directory (graphical Desktop Environments will usually
do this for you and create a directory named /media/something that
provides the mount-point for your removable device).
This means a folder's contents in a linux system can exist on a
different device than you would expect them to be:
/var can be on /dev/sdb1 (your root partition where /bin, /etc, /usr and
all the others are also located) and the contents of the subdirectory
/var/mail can be on a different partition (e.g. /dev/sdb2).
You could have something like that
/ on /dev/sdb1 (which I called "main" partition before)
/boot on /dev/sdb2
/var on /dev/sdb1
/var/mail on /dev/sdb3
/home on /dev/sdb4
While your original idea was to have (if I got it correctly)
/ on /dev/sdb1
/boot on /dev/sdb2
/var on /dev/sdb1
/var/mail on /dev/sdb1
/home on /dev/sdb3
I have not read it completely but this could probably help (If I was not
able to claify this completely):
