Hardy install over existing Ubuntu install

[Pat Brown]

I've got the newest release of Ubuntu 8.04 - the LTS version I believe.
When I run the install, will it overwrite everything or will it
recognize the Linux partition and simply replace the core files and
leave my home directory and documents folder alone? I'm backing things
up but don't know of a way to save all my emails outside of physically
saving all. But I'd like to install this to fix some issues I'm having
not being able to run updates.
