It is also one of two official installers available for Ubuntu, the other being called Ubiquity (itself based on parts of debian-installer) which was introduced in Ubuntu 6.06 (Dapper Drake).

It makes use of cdebconf (a re-implementation of debconf in C) to perform configuration at install time.

Originally, it was only supported under text-mode and ncurses. A graphical front-end (using GTK-DirectFB) was first introduced in Debian 4.0 (Etch). Since Debian 6.0 (Squeeze), it is used over Xorg instead of DirectFB.

debootstrap

debootstrap is software which allows installation of a Debian base system into a subdirectory of another, already installed operating system.[5] It needs access to a Debian repository and doesn't require an installation CD.[5] It can also be installed and run from another operating system or to create a "cross-debootstrapping", a rootfs for a machine of a different architecture,[5] for instance, OpenRISC.[6] There is also a largely equivalent version written in C – cdebootstrap, which is used in debian-installer.[5]

debootstrap can be used to install Debian in a system without using an installation disk but can also be used to run a different Debian flavor in a chroot environment.[7] This way it is possible to create a full (minimal) Debian installation which can be used for testing purposes, or for building packages in a "clean" environment (e.g., as pbuilder does).[7]
