Installs packages which have been retrieved from the chosen mirror or CD. Sets up the root password, and adds a non-root user. Updates the system clock and determines whether the clock is set to UTC or not. Selects the time zone, based on the location selected earlier. Allows the user to partition disks attached to the system, create file systems on the selected partitions, and attach them to the mountpoints. Included are also interesting features like a fully automatic mode or LVM support. This is the preferred partitioning tool in Ubuntu. Helps the user with the configuration of the LVM (Logical Volume Manager). Allows the user to set up Software RAID (Redundant Array of Inexpensive Disks). This Software RAID is usually superior to the cheap IDE (pseudo hardware) RAID controllers found on newer motherboards. Installs the most basic set of packages which would allow the computer to operate under Ubuntu when rebooted. Configures apt, mostly automatically, based on what media the installer is running from. Uses tasksel to select and install additional software. Detects currently installed operating systems on the computer and passes this information to the bootloader-installer, which may offer you an ability to add discovered operating systems to the bootloader’s start menu. This way the user could easily choose at the boot time which operating system to start. The various bootloader installers each install a boot loader program on the hard disk, which is necessary for the computer to start up using Linux without requiring further (removable) media, like floppy or CD-ROM. Many boot loaders allow the user to choose an alternate operating system each time the computer boots. 46
