draklive - A live distribution mastering tool

=head1 SYNOPSIS

draklive [options]

 Options:
   --help            long help message

   --install         install selected distribution in chroot
   --boot            prepare initrd and bootloader files
   --loop            build compressed loopback files
   --master          build master image
   --image           build compressed master image
   --replicator      build replicator image (to dump master on systems)

   --all             run all steps, from installation to mastering

   --clean           clean installation chroot and work directory

   --device <dev>    use this device for live recording (not needed
                     if the device already has the required label)
   --format          format selected device
   --record          record live on selected media
   --record-onthefly record live by creating master from loopback files
                     on the fly

   --initrd          build initrd only
   --post-install    run post install only (rpms and patches installation)

   --config-root <dir>
                     root directory containing config files and additionnal files
                     defaults to current directory if it contains a configuration file
                     else, "/etc/draklive" is used

   --config <file>   use this configuration file as live description
                     defaults to "config/live.cfg"

   --settings <file> use this file as live settings (key=value format)
                     defaults to "config/settings.cfg"
   --define key=value
                     set setting "key" to "value"
                     takes precedence over values from a settings file

   --all-regions     proceed with all configured regions

   --copy-wizard     run the copy wizard

   --boot-only       copy only boot files
                     (affects master/record steps)

   --boot-image <method>
                     create a boot image for the selected method
                     (affects master/record steps, implies --boot-only)

Examples:

 draklive --clean

 draklive --all

 draklive --record --device /dev/sdb1

 draklive --config config/live.cfg --install

=item B<--config>

Makes draklive use the next argument as a configuration file.
This file should contain an hash describing the live distribution,
meaning the system (chroot and boot), media (usb, cdrom, nfs),
and mount type (simple R/W union, union with squash files).

Here's a configuration sample:

  {
    settings {
        repository => '/mnt/ken/2006.0',
        root => '/chroot/live-move',
    },
    system => {
        kernel => '2.6.12-12mdk-i586-up-1GB',
        auto_install => 'config/auto_inst.cfg.pl',
        patch_install => 'config/patch-2006-live.pl',
        rpmsrate => 'config/rpmsrate',
        rpms => [
             'rpms/unionfs-kernel-2.6.12-12mdk-i586-up-1GB-1.1.1.1.20051124.1mdk-1mdk.i586.rpm'
        ],
        patches => [
             'patches/halt.loopfs.patch',
        ],
        vga_mode => 788,
    },
    media => {
        storage => 'cdrom',
    },
    mount => $predefined{mounts}{squash_union}
  };

=item B<--settings>

Makes draklive load the next argument as a file in key=value format
into the $live->{settings} hash ($live being the global live configuration hash).

Built-in keys:
  arch: build architecture
  builddir: directory hosting build files (initrd, loopbacks, images)
  chroot: directory hosting chrooted installations
  region: use the matching set of langs from the regions configuration hash
  repository: path to the Mandriva distribution repository (ftp/http/local)

Example keys:
  desktop
