live-build - the Debian Live tool suite
lb COMMAND [-h|--help] [-u|--usage] [-v|--version] [--breakpoints]
[--conffile] [--debug] [--force] [--quiet] [--verbose]
live-build is a set of scripts to build Debian Live system images. The
idea behind live-build is a tool suite that uses a configuration
directory to completely automate and customize all aspects of building
a Live image.
The COMMAND is a name of a live-build command (see below).
More documentation about how to use live-build is available in the
individual manpages for each helper and in the manual at
Shared live-build options
The following command line options are supported by all live-build
display help and exit.
show usage and exit.
output version information and exit.
Common live-build options
The following command line options are supported by most live-build
programs. See the man page of each program for a complete explanation
of what each option does.
run with breakpoints.
use custom configuration file.
show debug information.
force helper execution, even if stage file exists.
We divide live-build into high level ("porcelain") commands and low
level ("plumbing") commands.
Here is the complete list of all available live-build commands. See
their man pages for additional documentation.
HIGH-LEVEL COMMANDS (PORCELAIN)
We separate the porcelain commands into the main commands and some
ancillary user utilities.
Main porcelain commands
create configuration for live-build
create the first stage by bootstrapping a basic debian system
create the second stage by customizing the chroot
create the third stage by generating a binary image
create the optional fourth stage by generating a source image
clean up system build directories
generic live-build wrapper
alias for all stages
helper for using a local live-build
ensure that a system is built as root
LOW-LEVEL COMMANDS (PLUMBING)
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, they
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.
Note that the interface (set of options and the semantics) to these
low-level commands are meant to be a lot more stable than Porcelain
level commands. The interface to Porcelain commands on the other hand
are subject to change in order to improve the end user experience.

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 or config/stage_helper (where "stage" of
course, is replaced with the name of the stage that they belong to, and
"helper" with the name of the helper).
For example, lb_bootstrap_debootstrap uses files named config/bootstrap
and config/bootstrap_debootstrap to read the options it will use. See
the man pages of individual commands for details about the names and
formats of the files they use. Generally, these files contain variables
with values assigned, one variable per line. Some programs in
live-build use pairs of values or slightly more complicated variable
Note that live-build will respect environment variables which are
present in the context of the shell it is running. If variables can be
read from config files, then they override environment variables, and
if command line options are used, they override values from config
files. If no value for a given variable can be found and thus is unset,
live-build will automatically set it to the default value.
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 or config/stage_helper.arch, and config/stage.dist or
config/stage_helper.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.
All config files are shell scripts which are sourced by a live-build
program. That means they have to follow the normal shell syntax. You
can also put comments in these files; lines beginning with "#" are
