live-helper - the Debian Live tool suite
lh_* [-h|--help] [-u|--usage] [-v|--version]
live-helper is used to help you build a Debian Live system. The
philosophy behind live-helper is to provide a collection of small,
simple, and easily understood tools that are used on a config directory
to automate all aspects of building a Debian Live image.
Here is the complete list of available live-helper commands. See their
man pages for additional documentation.
generic live-helper wrapper
meta-helper for lh_binary_*
meta-helper for lh_bootstrap_*
meta-helper for lh_bootstrap, lh_chroot, lh_binary, and lh_source
meta-helper for lh_chroot_*
clean up build directories
create configuration directory
meta-helper for lh_source_*
ensure that a system is built as root
If a program’s name starts with "lh_", and the program is not on the
above list, then it is not part of the live-helper package, but it
should still work like the other programs described on this page.
LIVE-HELPER CONFIG FILES
Many live-helper 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-helper commands, some additional files can be used to
configure the behavior of specific live-helper 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, lh_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-helper use pairs of values or slightly more complicated variable
Note that live-helper will respects 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-helper 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 exists, 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-helper
program. That means they have to follow the normal shell syntax. You
can also put comments in these files; lines beginning with "#" are
