Settings lost after re-installation?

[Etyx]

Right now I'm running ubuntu with three partitions. /, /home and a swap partition.

If I did a clean re-installation what exactly would be lost afterwards? /home obviously not but what about all the system settings, visual individualization or downloaded software from the ubuntu software center for example. Furthermore, I'd like to know why a clean re-installation is regarded better than an upgrade.

A clean installation will only have the installation.

Which means what exactly?

your /home is where are stored your data and settings, so reinstalling only change /, not /home (only take care to not format it of course :mad:)

And all the system settings are saved in /home?
