    While <i>live-manual</i> is primarily focused on helping you build a live system and not on end-user topics, an end user may find some useful information in these sections:  <a href="#the-basics">The Basics</a>  covers downloading prebuilt images and preparing images to be booted from media or the network, either using the web builder or running <i>live-build</i> directly on your system.  <a href="#customizing-run-time-behaviours">Customizing run time behaviours</a>  describes some options that may be specified at the boot prompt, such as selecting a keyboard layout and locale, and using persistence.

    First, read this chapter,  <a href="#about-manual">About this manual</a>,  from the beginning and ending with the  <a href="#terms">Terms</a>  section. Next, skip to the three tutorials at the front of the  <a href="#examples">Examples</a>  section designed to teach you image building and customization basics. Read  <a href="#using-the-examples">Using the examples</a>  first, followed by  <a href="#tutorial-1">Tutorial 1: A default image</a>,   <a href="#tutorial-2">Tutorial 2: A web browser utility</a>  and finally  <a href="#tutorial-3">Tutorial 3: A personalized image</a>.

    We encourage you to return to more in-depth study of the manual, perhaps next reading  <a href="#the-basics">The basics</a>,  skimming or skipping  <a href="#building-netboot-image">Building a netboot image</a>,  and finishing by reading the  <a href="#customization-overview">Customization overview</a>  and the chapters that follow it. By this point, we hope you are thoroughly excited by what can be done with live systems and motivated to read the rest of the manual, cover-to-cover.

    <b>Live system</b>: An operating system that can boot without installation to a hard drive. Live systems do not alter local operating system(s) or file(s) already installed on the computer hard drive unless instructed to do so. Live systems are typically booted from media such as CDs, DVDs or USB sticks. Some may also boot over the network (via netboot images, see  <a href="#building-netboot-image">Building a netboot image</a>),  and over the Internet (via the boot parameter <tt>fetch=URL</tt>, see  <a href="#webbooting">Webbooting</a>).

The <b>testing</b> distribution, temporarily codenamed <b>buster</b>, is the staging area for the next <b>stable</b> release. A major advantage of using this distribution is that it has more recent versions of software relative to the <b>stable</b> release. The <b>unstable</b> distribution, permanently codenamed <b>sid</b>, is where active development of Debian occurs. Generally, this distribution is run by developers and those who like to live on the edge. Throughout the manual, we tend to use codenames for the releases, such as <b>buster</b> or <b>sid</b>, as that is what is supported by the tools themselves.

    Since it takes a while to build the manual in all supported languages, authors may find it convenient to use one of the fast proofing shortcuts when reviewing the new documentation they have added to the English manual. Using <tt>PROOF=1</tt> builds <i>live-manual</i> in html format, but without the segmented html files, and using <tt>PROOF=2</tt> builds <i>live-manual</i> in pdf format, but only the A4 and letter portraits. That is why using either of the <tt>PROOF=</tt> possibilities can save up a considerable amount of time, e.g:

    <i>live-manual</i> comes with two utilities that can greatly help translators to find untranslated and changed strings. The first one is "make translate". It launches an script that tells you in detail how many untranslated strings there are in each .po file. The second one, the "make fixfuzzy" target, only acts upon changed strings but it helps you to find and fix them one by one.

    Keep in mind that even though these utilities might be really helpful to do translation work on the command line, the use of an specialized tool like <i>poedit</i> is the recommended way to do the task. It is also a good idea to read the Debian localization (l10n) documentation and, specifically to <i>live-manual</i>, the  <a href="#guidelines-translators">Guidelines for translators</a>.

    This chapter contains a brief overview of the build process and instructions for using the three most commonly used image types. The most versatile image type, <tt>iso-hybrid</tt>, may be used on a virtual machine, optical medium or USB portable storage device. In certain special cases, as explained later, the <tt>hdd</tt> type may be more suitable. The chapter includes detailed instructions for building and using a <tt>netboot</tt> type image, which is a bit more involved due to the setup required on the server. This is an slightly advanced topic for anyone who is not already familiar with netbooting, but it is included here because once the setup is done, it is a very convenient way to test and deploy images for booting on the local network without the hassle of dealing with image media.

    Regardless of the image type, you will need to perform the same basic steps to build an image each time. As a first example, create a build directory, change to that directory and then execute the following sequence of <i>live-build</i> commands to create a basic ISO hybrid image containing a default live system without X.org. It is suitable for burning to CD or DVD media, and also to copy onto a USB stick.

    The name of the working directory is absolutely up to you, but if you take a look at the examples used throughout <i>live-manual</i>, it is a good idea to use a name that helps you identify the image you are working with in each directory, especially if you are working or experimenting with different image types. In this case you are going to build a default system so let's call it, for example, live-default.

    In this specific case, a <tt>lb clean --binary</tt> would not be enough to clean up the necessary stages. The cause for this is that in netboot setups, a different initramfs configuration needs to be used which <i>live-build</i> performs automatically when building netboot images. Since the initramfs creation belongs to the chroot stage, switching to netboot in an existing build directory means to rebuild the chroot stage too. Therefore, <tt>lb clean</tt> (which will remove the chroot stage, too) needs to be used.

    In a network boot, the client runs a small piece of software which usually resides on the EPROM of the Ethernet card. This program sends a DHCP request to get an IP address and information about what to do next. Typically, the next step is getting a higher level bootloader via the TFTP protocol.

    Webbooting is a convenient way of retrieving and booting live systems using the internet as a means. The requirements for webbooting are very few. On the one hand, you need a medium with a bootloader, an initial ramdisk and a kernel. On the other hand, a web server to store the squashfs files which contain the filesystem.

    As usual, you can build the images yourself or use the prebuilt files, which are available on the project's homepage at ‹<a href="http://debian-live.alioth.debian.org/" target="_top">http://debian-live.alioth.debian.org/</a>›. Using prebuilt images would be handy for doing initial testing until one can fine tune their own needs. If you have built a live image you will find the files needed for webbooting in the build directory under <tt>binary/live/</tt>. The files are called <tt>vmlinuz</tt>, <tt>initrd.img</tt> and <tt>filesystem.squashfs</tt>.

    The files are to be found under the <tt>live/</tt> directory. In this specific case, it would be <tt>/mnt/live/</tt>. This method has the disadvantage that you need to be root to be able to mount the image. However, it has the advantage that it is easily scriptable and thus, easily automatized.

    But undoubtedly, the easiest way of extracting the files from an iso image and uploading it to the web server at the same time, is using the midnight commander or <i>mc</i>.

    Live configurations rarely are perfect on the first try. It may be fine to pass <tt>lb config</tt> options from the command-line to perform a single build, but it is more typical to revise those options and build again until you are satisfied. To support these changes, you will need auto scripts which ensure your configuration is kept in a consistent state.

    The <tt>lb config</tt> command stores the options you pass to it in <tt>config/*</tt> files along with many other options set to default values. If you run <tt>lb config</tt> again, it will not reset any option that was defaulted based on your initial options. So, for example, if you run <tt>lb config</tt> again with a new value for <tt>--binary-images</tt>, any dependent options that were defaulted for the old image type may no longer work with the new ones. Nor are these files intended to be read or edited. They store values for over a hundred options, so nobody, let alone yourself, will be able to see in these which options you actually specified. And finally, if you run <tt>lb config</tt>, then upgrade <i>live-build</i> and it happens to rename an option, <tt>config/*</tt> would still contain variables named after the old option that are no longer valid.

    For all these reasons, <tt>auto/*</tt> scripts will make your life easier. They are simple wrappers to the <tt>lb config</tt>, <tt>lb build</tt> and <tt>lb clean</tt> commands that are designed to help you manage your configuration. The <tt>auto/config</tt> script stores your <tt>lb config</tt> command with all desired options, the <tt>auto/clean</tt> script removes the files containing configuration variable values, and the <tt>auto/build</tt> script keeps a <tt>build.log</tt> of each build. Each of these scripts is run automatically every time you run the corresponding <tt>lb</tt> command. By using these scripts, your configuration is easier to read and is kept internally consistent from one revision to the next. Also, it will be much easier for you identify and fix options which need to change when you upgrade <i>live-build</i> after reading the updated documentation.

    Live system configuration options are divided into build-time options which are options that are applied at build time and boot-time options which are applied at boot time. Boot-time options are further divided into those occurring early in the boot, applied by the <i>live-boot</i> package, and those that happen later in the boot, applied by <i>live-config</i>. Any boot-time option may be modified by the user by specifying it at the boot prompt. The image may also be built with default boot parameters so users can normally just boot directly to the live system without specifying any options when all of the defaults are suitable. In particular, the argument to <tt>lb --bootappend-live</tt> consists of any default kernel command line options for the Live system, such as persistence, keyboard layouts, or timezone.

    The build process is divided into stages, with various customizations applied in sequence in each. The first stage to run is the <b>bootstrap</b> stage. This is the initial phase of populating the chroot directory with packages to make a barebones Debian system. This is followed by the <b>chroot</b> stage, which completes the construction of chroot directory, populating it with all of the packages listed in the configuration, along with any other materials. Most customization of content occurs in this stage. The final stage of preparing the live image is the <b>binary</b> stage, which builds a bootable image, using the contents of the chroot directory to construct the root filesystem for the Live system, and including the installer and any other additional material on the target medium outside of the Live system's filesystem. After the live image is built, if enabled, the source tarball is built in the <b>source</b> stage.

    Within each of these stages, there is a particular sequence in which commands are applied. These are arranged in such a way as to ensure customizations can be layered in a reasonable fashion. For example, within the <b>chroot</b> stage, preseeds are applied before any packages are installed, packages are installed before any locally included files are copied, and hooks are run later, after all of the materials are in place.

    Perhaps the most basic customization of a live system is the selection of packages to be included in the image. This chapter guides you through the various build-time options to customize <i>live-build</i>'s installation of packages. The broadest choices influencing which packages are available to install in the image are the distribution and archive areas. To ensure decent download speeds, you should choose a nearby distribution mirror. You can also add your own repositories for backports, experimental or custom packages, or include packages directly as files. You can define lists of packages, including metapackages which will install many related packages at once, such as packages for a particular desktop or language. Finally, a number of options give some control over <i>apt</i>, or if you prefer, <i>aptitude</i>, at build time when packages are installed. You may find these handy if you use a proxy, want to disable installation of recommended packages to save space, or need to control which versions of packages are installed via APT pinning, to name a few possibilities.

    This supercedes the older predefined list method supported in <tt>live-build</tt> 2.x. Unlike predefined lists, task metapackages are not specific to the Live System project.

    Desktop and language tasks are special cases that need some extra planning and configuration. Live images are different from Debian Installer images in this respect. In the Debian Installer, if the medium was prepared for a particular desktop environment flavour, the corresponding task will be automatically installed. Thus, there are internal <tt>gnome-desktop</tt>, <tt>kde-desktop</tt>, <tt>lxde-desktop</tt> and <tt>xfce-desktop</tt> tasks, none of which are offered in <tt>tasksel</tt>'s menu.

    When developing a desktop live image, the image typically boots directly to a working desktop, the choices of both desktop and default language having been made at build time, not at run time as in the case of the Debian Installer.

Therefore, we suggest you review the difference turning off recommends makes to your packages list (see the <tt>binary.packages</tt> file generated by <tt>lb build</tt>) and re-include in your list any missing packages that you still want installed. Alternatively, if you find you only want a small number of recommended packages left out, leave recommends enabled and set a negative APT pin priority on selected packages to prevent them from being installed, as explained in  <a href="#apt-pinning">APT pinning</a>.

    This chapter discusses fine-tuning customization of the live system contents beyond merely choosing which packages to include. Includes allow you to add or replace arbitrary files in your live system image, hooks allow you to execute arbitrary commands at different stages of the build and at boot time, and preseeding allows you to configure packages when they are installed by supplying answers to debconf questions.

    While ideally a live system would include files entirely provided by unmodified packages, it is sometimes convenient to provide or modify some content by means of files. Using includes, it is possible to add (or replace) arbitrary files in your live system image. <i>live-build</i> provides two mechanisms for using them:

    Chroot local includes can be used to add or replace files in the chroot/Live filesystem so that they may be used in the Live system. A typical use is to populate the skeleton user directory (<tt>/etc/skel</tt>) used by the Live system to create the live user's home directory. Another is to supply configuration files that can be simply added or replaced in the image without processing; see  <a href="#chroot-local-hooks">Chroot local hooks</a>  if processing is needed.

    To include material such as documentation or videos on the medium filesystem so that it is accessible immediately upon insertion of the medium without booting the Live system, you can use binary local includes. This works in a similar fashion to chroot local includes. For example, suppose the files <tt>~/video_demo.*</tt> are demo videos of the live system described by and linked to by an HTML index page.

We have also created an encrypted partition, which can be located in the same usb stick to carry it around and we have configured the encrypted partition to be used as persistence store. So now, we only need to boot the live system. At boot time, <i>live-boot</i> will prompt us for the passphrase and will mount the encrypted partition to be used for persistence.

    If possible, isolate the failing case to the smallest possible change that breaks. It is not always easy to do this so if you cannot manage it for your report, do not worry. However, if you plan your development cycle well, using small enough change sets per iteration, you may be able to isolate the problem by constructing a simpler 'base' configuration that closely matches your actual configuration plus just the broken change set added to it. If you have a hard time sorting out which of your changes broke, it may be that you are including too much in each change set and should develop in smaller increments.

This violates the integrity of those packages and that, as the comment header warns, may have unforeseen consequences. That is why using a minimal <i>debootstrap</i> is the recommended way of achieving this goal.

    Look up the meaning of words in a dictionary or encyclopedia if you do not know how to express certain concepts in English. But keep in mind that a dictionary can either be your best friend or can turn into your worst enemy if you do not know how to use it correctly.

    English has the largest vocabulary that exists (with over one million words). Many of these words are borrowings from other languages. When looking up the meaning of words in a bilingual dictionary the tendency of a non-native speaker of English is to choose the one that sounds more similar in their mother tongue. This often turns into an excessively formal discourse which does not sound quite natural in English.

    As a general rule, if a concept can be expressed using different synonyms, it is a good advice to choose the first word proposed by the dictionary. If in doubt, choosing words of Germanic origin (Usually monosyllabic words) is often the right thing to do. Be warned that these two techniques might produce a rather informal discourse but at least your choice of words will be of wide use and generally accepted.

    So they should refrain from adding personal comments or extra bits of information of their own. If they want to add a comment for other translators working on the same documents, they can leave it in the space reserved for that.

    It is perfectly acceptable however, to include a word or an expression in brackets in the translated text if, and only if, that makes the meaning of a difficult word or expression clearer to the reader.

    Documents written in English make an extensive use of the impersonal form "you". In some other languages that do not share this characteristic, this might give the false impression that the original texts are directly addressing the reader when they are actually not doing so.

    Translators working initially with <b>pot</b> files and later on with <b>po</b> files will find many markup features in the strings.

    Even though the code blocks are usually untranslatable, including them in the translation is the only way to score a 100% complete translation.
