Installing new ubuntu, keeping /home partition

[Colin Law]

Hi

I have a dual boot setup using grub with XP and ubuntu.

I am currently on 8.10 and wish to try 9.04 without burning my boats
so I wish to install it but keep 8.10 working till I have confirmed
that 9.04 is ok for me.  I have /home in a separate partition and I
have a spare partition to install 9.04 into.  Am I right in thinking
that I should be able to install 9.04 and have it use the home
partition that I already have, and that I should be able to boot into
either ubuntu (or XP) as I wish?

If so I am ready to do the install (from the standard 9.04 CD), is
there anything I have to watch out for when doing this?  Is it obvious
how to tell it to use the existing home partition without overwriting
it?

I have googled but not found quite what I need.
