Within the distribution archive, archive areas are major divisions of the archive. In Debian, these are #{main}#, #{contrib}# and #{non-free}#. Only #{main}# contains software that is official a part of the Debian distribution, hence that is the default. One or more values may be specified, e.g.

Experimental support is available for some Debian derivatives through a #{--mode}# option. By default, this option is set to #{debian}#, even if you are building on a non-Debian system. If you specify #{--mode ubuntu}# or #{--mode emdebian}#, the distribution names and archive areas for the specified derivative are supported instead of the ones for Debian. The mode also modifies live-build behaviour to suit the derivatives.

*Note:* The projects for whom these modes were added are primarily responsible for supporting users of these options. The Debian live project, in turn, provides development support on a best-effort basis only, based on feedback from the derivative projects as we do not develop or support these derivatives ourselves.

You should also put the GPG key used to sign the repository into #{config/chroot_sources/your-repository.{binary,chroot}.gpg}# files.

Note: some preconfigured package repositories are available for easy selection through the #{--repository}# option, e.g. for enabling live snapshots, a simple command is enough to enable it:

In addition to these lists, live-build supports four virtual package lists: #{gnome-desktop}#, #{kde-desktop}#, #{lxde-desktop}# and #{xfce-desktop}#, each of which provide a more extensive selection of packages that corresponds with Debian Installer defaults for these desktop environments. See {Desktop and language tasks}#desktop-and-language-tasks for more details.

Note: The prebuilt GNOME, KDE, LXDE and XFCE images available for download at http://live.debian.net are built using the corresponding virtual #{*-desktop}# lists.

The default location for the list files on your system is #{/usr/share/live/build/lists/}#. To determine the packages in a given list, read the corresponding file, paying attention to included files and conditionals as described in the following sections.

For background, please first read the #{apt_preferences(5)}# man page. APT pinning can be configured either for build time, or else for run time. For the former, create #{config/chroot_apt/preferences}#. For the latter, create #{config/chroot_local-includes/etc/apt/preferences}#.

Let's say you are building a Squeeze live system but need all #{live-*}# packages to be installed from Sid at build time. You need to add Sid to your APT sources and pin it so that only the packages you want are installed from it at build time and all others are taken from the target system distribution, Squeeze. The following will accomplish this:

*{Note:}* Wildcards can be used in package names (e.g. *{Package: live-*}*) with Apt version 0.8.14 or higher. This means that it works with Wheezy using:

Negative pin priorities will prevent a package from being installed, as in the case where you do not want a package that is recommended by another package. Suppose you are building an LXDE image using #{--packages-lists lxde}# option, but don't want the user prompted to store wifi passwords in the keyring. This list includes #{gdm}#, which depends on #{gksu}#, which in turn recommends #{gnome-keyring}#. So you want to omit the recommended #{gnome-keyring}# package. This can be done by adding the following stanza to #{config/chroot_apt/preferences}#:
