“Like the Ubuntu 11.04 installer, the Kubuntu 11.04 installation
program configures just two partitions by default. These are for /,
the root directory, and Swap, disk space for use as virtual memory.
To make upgrades less tasking, it is recommended that a separate
partition be created for /home, the directory where your home
folder will be located.“This article presents a step-by-step guide on how to configure
these partitions manually. A similar article for Ubuntu 11.04 is
available here. Note that this article is based on the graphical
installation program, not the Alternate installer, which uses an
ncurses-based installation program.”
