These scripts -are also referred to as "commands". - -The idea behind live-build is to be a framework that uses a configuration -directory to completely automate and customize all aspects of building a -Live image. - -Many concepts are similar to those used to build Debian packages with -/{debhelper}/: - -_* The scripts have a central location for configuring their operation. In -/{debhelper}/, this is the #{debian/}# subdirectory of a package tree. For -example, dh_install will look, among others, for a file called -#{debian/install}# to determine which files should exist in a particular -binary package. In much the same way, live-build stores its configuration -entirely under a #{config/}# subdirectory. - -_* The scripts are independent - that is to say, it is always safe to run -each command. - -Unlike /{debhelper}/, live-build provides the tools to generate a skeleton -configuration directory. This could be considered to be similar to tools -such as /{dh-make}/. For more information about these tools, read on, since -the remainder of this section discuses the four most important -commands. Note that the preceding #{lb}# is a generic wrapper for live-build -commands. - -_* *{lb config}*: Responsible for initializing a Live system configuration -directory. See {The lb config command}#lb-config for more information. - -_* *{lb build}*: Responsible for starting a Live system build. See {The lb -build command}#lb-build for more information. - -_* *{lb clean}*: Responsible for removing parts of a Live system build. See -{The lb clean command}#lb-clean for more information. - -3~lb-config The #{lb config}# command - -As discussed in {live-build}#live-build, the scripts that make up live-build -read their configuration with the #{source}# command from a single directory -named #{config/}#. As constructing this directory by hand would be -time-consuming and error-prone, the #{lb config}# command can be used to -create the initial skeleton configuration tree. - -Issuing #{lb config}# without any arguments creates the #{config/}# -subdirectory which is populated with some default settings in configuration -files, and two skeleton trees named #{auto/}# and #{local/}#. - -code{ - - $ lb config - [2015-01-06 19:25:58] lb config - P: Creating config tree for a debian/stretch/i386 system - P: Symlinking hooks... - -}code - -Using #{lb config}# without any arguments would be suitable for users who -need a very basic image, or who intend to provide a more complete -configuration via #{auto/config}# later (see {Managing a -configuration}#managing-a-configuration for details). - -Normally, you will want to specify some options. For example, to specify -which package manager to use while building the image: - -code{ - - $ lb config --apt aptitude - -}code - -It is possible to specify many options, such as: - -code{ - - $ lb config --binary-images netboot --bootappend-live "boot=live components hostname=live-host username=live-user" ... - -}code - -A full list of options is available in the #{lb_config}# man page. - -3~lb-build The #{lb build}# command - -The #{lb build}# command reads in your configuration from the #{config/}# -directory. It then runs the lower level commands needed to build your Live -system. - -3~lb-clean The #{lb clean}# command - -It is the job of the #{lb clean}# command to remove various parts of a build -so subsequent builds can start from a clean state. By default, #{chroot}#, -#{binary}# and #{source}# stages are cleaned, but the cache is left -intact. Also, individual stages can be cleaned. For example, if you have -made changes that only affect the binary stage, use #{lb clean --binary}# -prior to building a new binary. If your changes invalidate the bootstrap -and/or package caches, e.g. changes to #{--mode}#, #{--architecture}#, or -#{--bootstrap}#, you must use #{lb clean --purge}#. See the #{lb_clean}# man -page for a full list of options. - -2~live-boot The live-boot package - -live-boot is a collection of scripts providing hooks for the -/{initramfs-tools}/, used to generate an initramfs capable of booting live -systems, such as those created by live-build. This includes the live system -ISOs, netboot tarballs, and USB stick images. - -At boot time it will look for read-only media containing a #{/live/}# -directory where a root filesystem (often a compressed filesystem image like -squashfs) is stored. If found, it will create a writable environment, using -aufs, for Debian like systems to boot from. - -More information on initial ramfs in Debian can be found in the Debian Linux -Kernel Handbook at http://kernel-handbook.alioth.debian.org/ in the chapter -on initramfs. - -2~live-config The live-config package - -live-config consists of the scripts that run at boot time after live-boot to -configure the live system automatically. It handles such tasks as setting -the hostname, locales and timezone, creating the live user, inhibiting cron -jobs and performing autologin of the live user. |
