37 $PN - build process script for generating a (grml based) Linux Live-ISO
39 Usage: $PN [options, see as follows]
41 -a <architecture> architecture; available values: i386 and amd64
42 -b build the ISO without updating the chroot via FAI
43 -B build the ISO without touching the chroot (skips cleanup)
44 -c <classe[s]> classes to be used for building the ISO via FAI
45 -C <configfile> configuration file for grml-live
46 -d <date> use specified date instead of build time as date of release
47 -D <configdir> use specified configuration directory instead of /etc/grml/fai
48 -F force execution without prompting
49 -g <grml_name> set the grml flavour name
50 -h display short usage information and exit
51 -i <iso_name> name of ISO
52 -I <src_directory> directory which provides files that should become
53 part of the chroot/ISO
54 -n skip generation of ISO
55 -N bootstrap (build chroot) only, do not create files for ISO
56 -o <output_directory> main output directory of the build process
58 -r <release_name> release name
59 -s <suite> Debian suite; values: etch, lenny, squeeze, sid
60 -t <template_directory> place of the templates
61 -u update existing chroot instead of rebuilding it from scratch
62 -v <version_number> specify version number of the release
63 -V increase verbosity in the build process
64 -z use ZLIB instead of LZMA/XZ compression
69 $PN -c GRMLBASE,GRML_MEDIUM,I386 -o /dev/shm/grml
70 $PN -c GRMLBASE,GRML_SMALL,REMOVE_DOCS,I386 -g grml-small -v 1.0
71 $PN -c GRMLBASE,GRML_FULL,I386 -i grml_0.0-1.iso -v 0.0-1
72 $PN -c GRMLBASE,GRML_FULL,I386 -s sid -V -r 'grml-live rocks'
