:B~ Personalizando conteúdo
1~customization-overview Visão geral sobre personalização
This chapter gives an overview of the various ways in which you may
customize a live system.
2~ Configuração de tempo de construção X tempo de inicialização
As opções de configuração do sistema Live são divididas em opções de tempo
de compilação que são as opções aplicadas em tempo de compilação e opções de
tempo de inicialização que são aplicadas em tempo de inicialização. Opções
de inicialização são divididas naquelas que ocorrem em início do
inicialização, aplicadas pelo pacote live-boot e aquelas que acontecem no
final da inicialização, aplicadas pelo live-config. Qualquer opção de
inicialização pode ser modificada pelo usuário, especificando a no prompt de
inicialização. A imagem também pode ser construída com os parâmetros de
inicialização padrão para que os usuários possam normalmente apenas
inicializar diretamente pelo sistema live, sem especificar quaisquer opções
quando todos os padrões são adequados. Em particular, o argumento para #{lb
--bootappend-live}# consiste de quaisquer opções padrão de kernel de linha
de comando para o sistema live, tais como persistência, layouts de teclado,
ou fuso horário. Veja {Personalizando local e
linguagem}#customizing-locale-and-language, por exemplo.
Build-time configuration options are described in the #{lb config}# man
page. Boot-time options are described in the man pages for live-boot and
live-config. Although the live-boot and live-config packages are installed
within the live system you are building, it is recommended that you also
install them on your build system for easy reference when you are working on
your configuration. It is safe to do so, as none of the scripts contained
within them are executed unless the system is configured as a live system.
2~stages-of-the-build Etapas da construção
The build process is divided into stages, with various customizations
applied in sequence in each. The first stage to run is the *{bootstrap}*
stage. This is the initial phase of populating the chroot directory with
packages to make a barebones Debian system. This is followed by the
*{chroot}* 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 *{binary}* 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 *{source}* 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 *{chroot}* 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.
2~ Complementar lb config com arquivos
Although #{lb config}# creates a skeletal configuration in the #{config/}#
directory, to accomplish your goals, you may need to provide additional
files in subdirectories of #{config/}#. Depending on where the files are
stored in the configuration, they may be copied into the live system's
filesystem or into the binary image filesystem, or may provide build-time
configurations of the system that would be cumbersome to pass as
command-line options. You may include things such as custom lists of
packages, custom artwork, or hook scripts to run either at build time or at
boot time, boosting the already considerable flexibility of debian-live with
code of your own.
2~ Tarefas de personalização
Os capítulos seguintes são organizados pelos tipos de personalização de
tarefas que os usuários normalmente executam: {Personalizar a instalação de
pacote}#customizing-package-installation, {Personalizar
conteúdos}#customizing-package-installation, e {Personalizar localizade e
linguagem}#customizing-locale-and-language cobrem apenas algumas das coisas
que você pode querer fazer.
