$PN - build process script for generating a (grml based) Linux Live-ISO
Usage: $PN [options, see as follows]
-a <architecture> architecture; available values: i386, amd64 + arm64
-A clean build directories before and after running
-b build the ISO without updating the chroot via FAI
-B build the ISO without touching the chroot (skips cleanup)
-c <classe[s]> classes to be used for building the ISO via FAI
-C <configfile> configuration file for grml-live
-d <date> use specified date instead of build time as date of release
-D <configdir> use specified configuration directory instead of /etc/grml/fai
-e <iso_name> extract ISO and squashfs contents from iso_name
-F force execution without prompting
-g <grml_name> set the grml flavour name
-h display short usage information and exit
-i <iso_name> name of ISO
-I <src_directory> directory which provides files that should become
part of the chroot/ISO
-n skip generation of ISO
-N bootstrap (build chroot) only, do not create files for ISO
-o <output_directory> main output directory of the build process
-q skip mksquashfs
-Q skip netboot package build
-r <release_name> release name
-s <suite> Debian suite/release, like: stable, testing, unstable
-S <script_directory> place of scripts (defaults to /usr/share/grml-live/scripts)
-t <template_directory> place of the templates
-u update existing chroot instead of rebuilding it from scratch
-U <username> arrange output to be owned by specified username
-v <version_number> specify version number of the release
-V increase verbosity in the build process
-w <date> wayback machine, build system using Debian archives
from specified date
-z use ZLIB instead of LZMA/XZ compression
Usage examples:
$PN
$PN -c GRMLBASE,GRML_FULL,AMD64 -o /dev/shm/grml
$PN -c GRMLBASE,GRML_FULL,AMD64 -i grml_0.0-1.iso -v 0.0-1
$PN -c GRMLBASE,GRML_FULL,AMD64 -s stable -V -r 'grml-ftw'
