LIVE-BUILD(7)

NOM
live-build - the Debian Live tool suite

SYNOPSIS
lb {-h|--help|-u|--usage|-v|--version}

lb COMMAND [OPTIONS]

DESCRIPTION
live-build est un ensemble de scripts pour construire des images de système live. L'idée derrière live-build est une suite d'outils qui utilise un répertoire de configuration pour automatiser complètement et personnaliser tous les aspects de la construction d'une image Live.

La COMMANDE est un nom d'une commande live-build (voir ci-dessous).

More documentation about how to use live-build is available in the individual manpages for each helper and in the manual at <https://live-team.pages.debian.net/live-manual/>.

COMMANDES LIVE-BUILD
We divide live-build into high level ("porcelain") commands, secondary major build stage ("porcelain") commands, and low level ("plumbing") commands.

Voici une liste complète de toutes les commandes live-build disponibles. Consultez leurs pages de manuel pour obtenir de la documentation additionnelle.

COMMANDES HAUT-NIVEAU (PORCELAINE)
Nous séparons les commandes porcelaine en commandes principales et en utilitaires utilisateur auxiliaires.

  Commandes porcelaine principales

lb config(1)
    creates configuration for live-build

lb build(1)
    executes the build process (by executing all of the secondary level major build stages in sequence)

lb clean(1)
    cleans up system build directories

  Commandes auxiliaires

lb(1)
    generic live-build script execution wrapper

SECONDARY-LEVEL BUILD COMMANDS (PORCELAIN)
The following are the commands that execute each major stage of the build process, in their necessary order of execution. Normally a user might just execute the higher level lb build(1) command rather than use these individually.

lb bootstrap(1)
    executes the first build stage, creating (bootstraping) a basic Debian root filesystem

lb chroot(1)
    executes the second build stage, building the live OS filesystem

lb installer(1)
    executes the third build stage, obtaining installer components (optional)

lb binary(1)
    executes the fourth build stage, generating the binary (live) image

lb source(1)
    executes the fifth build stage, generating a corresponding source image (optional)

LOW-LEVEL COMMANDS (PLUMBING) - BUILD STAGE COMPONENTS
The actual work of live-build is implemented in the low-level commands, called plumbing. They are not supposed to be used by end users, who should stick with porcelains as they ensure that all the different plumbing commands are executed in the right order. However, if you intend to reuse live-build commands in your own scripts, then the plumbings might be of interest for you.

Notez que l'interface (ensemble des options et des semantiques) de ces commandes bas-niveau sont pensées pour être beaucoup plus stables que les commandes de niveau Porcelaine. D'un autre côté, l'interface des commandes Porcelaine sont sujettes à changement afin d'améliorer l'expérience de l'utilisateur final.

  Bootstrap stage specific commands

lb bootstrap_archives(1)
    applies apt archive configuration

lb bootstrap_cache(1)
    in save mode, saves to cache a copy of the generated bootstrap directory, and in restore mode, restores from cache a previously generated copy

lb bootstrap_debootstrap(1)
    creates (bootstraps) a basic Debian root filesystem using debootstrap(8)

  Chroot stage specific commands

Note: The following chroot_ prefixed commands are used in building the live OS filesystem. Another set of similarly prefixed files are listed separately (see further down).

lb chroot_cache(1)
    in save mode, saves to cache a copy of the chroot directory, and in restore mode, restores from cache a previously generated copy

lb chroot_firmware(1)

LOW-LEVEL COMMANDS (PLUMBING) - CHROOT PREP COMPONENTS
The notes above under the section regarding build-stage specific low-level plumbing commands also apply here.

The following chroot_ prefixed commands are used throughout the various primary stages of the build process to apply and remove modifications to a chroot root filesystem. Generally these are used to apply modification that setup the chroot for use (execution of programs within it) during the build process, and later to remove those modification, unmounting things that were mounted, and making the chroot suitable for use as the root filesystem of the live OS to be bundled into the live image.

Note that the lb chroot_prep(1) command can be used to run these components in bulk.

lb chroot_prep(1)
    a helper to run the below components in bulk. The first parameter it takes is the execution mode - install or remove - to pass along. The second parameter is the set of helpers to run (they can be space or comma separated; remember to quote if space separated). Following this one or more of the special parameters 'mode-archives-chroot', 'mode-archives-binary', 'mode-archives-source' and 'mode-apt-install-binary' can optionally be used, to select the 'pass' parameter for lb chroot_archives(1) in the case of the first three (required if 'archives' is one of the helpers to be run), and to run lb chroot_apt(1) in 'install-binary' mode in the last case. Any remaining parameters (i.e. options like --force) are passed along to all scripts run. The second parameter can be simply 'all' in which case a default set of all components are used, or 'all-except-archives' which differs in skipping lb chroot_archives(1). Components can be specified without their filename 'chroot_' prefix for brevity. In remove mode the list of components are run in reverse order, so no need to provide them in reverse order yourself.

lb chroot_apt(1)
    manages apt configuration; in apply mode it applies configuration for use during build process, and in remove mode removes that configuration

lb chroot_archives(1)
    manages apt archive source lists; in apply mode it applies source list configurations suitable for use of the chroot in the build process, and in remove mode replaces that with a configuration suitable for the final live OS

lb chroot_debianchroot(1)
    manages a /etc/debian_chroot file

lb chroot_devpts(1)
    manages mounting of /dev/pts

lb chroot_dpkg(1)
    manages dpkg; in apply mode disabling things like the start-stop-daemon, and in remove mode enabling them again

lb chroot_hostname(1)
    manages the hostname configuration

lb chroot_hosts(1)
    manages the /etc/hosts file

lb chroot_proc(1)
    manages mounting of /proc

lb chroot_resolv(1)
    manages configuration of the /etc/resolv.conf file

lb chroot_selinuxfs(1)
    manages mounting of /sys/fs/selinux

lb chroot_sysfs(1)
    manages mounting of /sys

lb chroot_sysv-rc(1)
    manages the /usr/sbin/policy-rc.d file

lb chroot_tmpfs(1)
    manages configuration of dpkg to use a tmpfs filesystem

FICHIERS DE CONFIGURATION
Many live-build commands make use of files in the config/ directory to control what they do. Besides the common config/common, which is used by all live-build commands, some additional files can be used to configure the behavior of specific live-build commands. These files are typically named config/stage (where "stage" of course, is replaced with the name of the stage that they belong to).

Notez que live-build respectera les variables d'environment présentes dans le contexte du shell lancé. Si les variables peuvent être lues depuis les fichiers de configuration, alors elles prennent le pas sur les variables d'environement, et si les options en ligne de commande sont utilisées, elles sont prioritaires sur les fichiers de configuration. Si pour une variable donnée, aucune valeur ne peut être trouvée et donc, est non-paramétrèe, live-build la paramètrera automatiquement à la valeur par défaut.

In some rare cases, you may want to have different versions of these files for different architectures or distributions. If files named config/stage.arch and config/stage.dist exist, where "arch" is the same as the output of "dpkg --print-architecture" and "dist" is the same as the codename of the target distribution, then they will be used in preference to other, more general files.

Tous les fichiers de configuration sont des scripts shell qui sont sourcés par un programme live-build. Ceci signifie qu'ils doivent suivre la syntaxe de shell normale. Vous pouvez également mettre des commentaires dans ces fichiers; les lignes commençant par des "#" sont ignorées.
