This is a page for tracking how DebianInstaller is being used by third parties in custom images and other distributions.
Kenshi Muto maintains ISO images for Lenny, Etch and Sarge that use the newest 2.6.* kernel for i386 and amd64. http://kmuto.jp/debian/d-i/
BOSS GNU/Linux is an Indian Version of Linux developed at C-DAC, Chennai, India. BOSS is an acronym for Bharath Operating System Solutions. It provides Indian language support and additional features such as ?BossBulkDocument Converter, Boss Presentation Tool, SCIM, Plug-n-Play device support, automounting of all existing operating systems, BharateeyaaOO for OpenOffice with multiple Indian language support. BOSS is LSB 3.1 certified by FSG. BOSS uses d-i and the team found it really flexible enough to work with. BOSS Team will be proud to contribute to d-i and debian community as a whole. BOSS cds can be downloaded from http://bosslinux.in/BOSS/BOSS-Tarang/
Skolelinux is a woody-based Debian derivative that was the first distribution to ship with the DebianInstaller. The installer images are not actually modified for Skolelinux, only a couple more udebs are added to the CD. Debian-Edu is the sarge-based update to skolelinux which also used the DebianInstaller. The source to the added udebs is in their svn repository at svn://svn.debian.org/debian-edu/trunk/src/debian-edu-install
Ubuntu uses a customised version of the DebianInstaller for their installation CD. Their LiveCd used to use DebianInstaller as part of its boot process, although nowadays uses an initramfs-based boot process instead (Debian's live-initramfs package was derived from this). Their changes to the installer are available via bzr; see this wiki page for details. Their live CD uses a custom graphical installer (Ubiquity) with d-i as a backend for many operations.
Dick Visser has produced sarge ISO images that support the Areca SATA controller. http://www.tienhuis.nl/areca/
Sun Wah's distribution uses a graphical installer derived from d-i. These changes are in a subversion repository (where?) but have not been contributed back to the d-i developers.
Hiweed-Debian GNU/Linux is a Chinese distribution that apparently uses d-i's graphical installer.
Say GoodBye To Microsoft is a web site developed by Robert Millan that automates the process of downloading d-i and booting into it from windows.
DPHYS3 (Debian Powered Hosts Yet Simple, Version 3) is how the Department of Physics at the ETH Zurich deploys their over 150 Debian workstations automatically via netboot using a preseeded d-i.
Lihuen GNU/Linux is an Argentinian Debian Lenny-based distribution developed at the LINTI by students of the National University of La Plata, focused on education and low-level users. It adapted d-i giving it a new graphic theme and using preseeding to avoid localization options and low-level matters. Then it used debian-cd to create the ISO images.
If you have produced a customised image based on the DebianInstaller, please add it here. DebianInstaller/Modify, DebianInstaller/Build, DebianCustomCD, and DebianInstaller/Preseed are useful resources.
