38 $PN - build process script for generating a (grml based) Linux Live-ISO
40 Usage: $PN [options, see as follows]
42 -a <architecture> architecture; available values: i386 and amd64
43 -b build the ISO without updating the chroot via FAI
44 -B build the ISO without touching the chroot (skips cleanup)
45 -c <classe[s]> classes to be used for building the ISO via FAI
46 -C <configfile> configuration file for grml-live
47 -F force execution without prompting
48 -g <grml_name> set the grml flavour name
49 -h display short usage information and exit
50 -i <iso_name> name of ISO
51 -I <src_directory> directory which provides files that should become
52 part of the chroot/ISO
53 -n skip generation of ISO
54 -o <output_directory> main output directory of the build process
56 -r <release_name> release name
57 -s <suite> Debian suite; values: etch, lenny, squeeze, sid
58 -t <template_directory> place of the templates
59 -u update existing chroot instead of rebuilding it from scratch
60 -v <version_number> specify version number of the release
61 -V increase verbosity in the build process
62 -z use ZLIB instead of LZMA compression (depends on
63 squashfs-tools version)
68 $PN -c GRMLBASE,GRML_MEDIUM,I386 -o /dev/shm/grml
69 $PN -c GRMLBASE,GRML_SMALL,REMOVE_DOCS,I386 -g grml-small -v 1.0
70 $PN -c GRMLBASE,GRML_FULL,I386 -i grml_0.0-1.iso -v 0.0-1
71 $PN -c GRMLBASE,GRML_FULL,I386 -s sid -V -r 'grml-live rocks'
