1.2. About the Debian Live Project

1.2.1. Motivation

1.2.1.1. What is wrong with current live systems

There are already several Debian-based live systems and they are doing a great job. But, from the Debian perspective most of them have one or more of the following disadvantages:

  1. They are unofficial projects, developed outside of Debian.

  2. They mix different distributions, e.g. testing and unstable.

  3. They support i386 only.

  4. They modify the behaviour and/or appearance of packages by stripping them down to save space.

  5. They include unofficial packages.

  6. They ship custom kernels with additional patches that are not part of Debian.

  7. They are large and slow due to their sheer size and thus not suitable for rescue issues.

  8. They are not available in different flavours, e.g. CDs, DVDs, USB-stick and netboot images

1.2.1.2. Why create our own live system?

Debian is the Universal Operating System: Debian should have an official live system for showing around and to officially represent the true, one and only Debian system with the following main advantages:

  1. It would be an official Debian subproject.

  2. It reflects the (current) state of one distribution.

  3. It runs on as many architectures as possible.

  4. It consists of unchanged Debian packages only.

  5. It does not contain any unofficial packages.

  6. It uses an unaltered Debian kernel-image with no additional patches.

1.2.2. Philosophy

1.2.2.1. Only unchanged, official packages

We will only use official packages from the Debian repository in the "main" section (possibly contrib, although not decided yet). The non-free section is not part of Debian and therefore cannot be used at all for live systems.

We will not change any packages. Whenever we need to change something, we will do that in coordination with its package maintainer in Debian.

As an exception, our own packages such as live-helper or live-initramfs may temporarily be used from our own repository for development reasons (e.g. to create development snapshots). They will be uploaded to Debian on a regular basis.

1.2.2.2. No package configuration of the live system

In this phase we will not ship or install sample or alternative configurations. All packages are used in their default configuration as they are after a regular installation of Debian.

Whenever we need a different default configuration, we will do that in coordination with its package maintainer in Debian.

A system for configuring packages is provided using debconf in lh config (use --preseed FILE) allowing custom configured packages to be installed in your custom produced Debian Live images, but for official live images only default configuration will be used. For more information, please see Chapter 5, Customization.

Exception: There are a few essential changes needed to bring a live system to life (e.g. configuring pam to allow empty passwords). These essential changes have to be kept as minimal as possible and should be merged within the Debian repository if possible.

1.2.2.3. Live system to hard disk installer

For the moment we will not ship an installer to copy the live system to a partition on the hard disk. Although we keep the changes in the live system as drastically minimal as possible compared to a regular Debian installation, the live system does differ in a few essential points (see exceptions, guideline 2).

Therefore, we will ship a copy of the regular DebianInstaller (resp. Debian Installer, Graphical Installer) instead, to allow users to perform a regular Debian installation (and, of course, cdebootstrap and debootstrap are on the system too).

1.2.3. Contact

Mailing list

The primary contact for the project is the mailing list. You can email the list directly by addressing your mail to . The list archives are also available.

IRC

A number of users and developers are present in the #debian-live channel on OFTC. When asking a question on IRC, please be patient for an answer. If no answer is forthcoming, please email the mailing list.

BTS

The Debian Bug Tracking System (BTS) contains details of bugs reported by users and developers. Each bug is given a number, and is kept on file until it is marked as having been dealt with. For more information, please see Chapter 9, Reporting bugs.

Wiki

The Debian Live wiki is a place to gather information, discuss applied technologies, and document frameworks of Debian Live systems that go beyond the scope of this document.
