Okay, installer is smart enough to know all this things, and I would
go with the default options only, but I was trying to know somehow
what exactly was the purpose of having separate partitions and how
does it help....

This is the way I do it, assuming one disk:

/dev/sda1 100MB ext2 /boot
/dev/sda2 100MB ext2
/dev/sda3 xxxx swap /swap (make this as big as your RAM)
/dev/sda4 rest of disk extended-part
/dev/sda5 40GB xfs /
/dev/sda6 40GB xfs
/dev/sda7 rest of disk xfs /home

The small /boot partition formatted with ext2 guarantees that I
can boot. Some boot loaders didn't like xfs or Reiserfs in the past.

40-GB is big enough for all the OS stuff, along with /tmp.

The two unused partitions allow me to install the next release without
disturbing the current one. Grub will automatically set it up so you
can boot to the previous release if something goes wrong. You can
also manually mount the previous / if you need to copy configuration
files or other programs not a part of the OS release.

You can make installs in one pair of partitions one time, the other pair
for the next release, while /home stays the same, as long as you don't
accidentally format it!

There are lots of other ways to do it, your mileage may vary...
