-=head1 NAME
-
-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
-
- --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 <file> use this configuration file as live description
-
- --region <region> use the matching set of langs
- (from the regions configuration hash)
- --all-regions proceed with all configured regions
-
- --copy-wizard run the copy wizard
-
- --boot-only consider only boot media
- (affects boot/master/format/record steps)
-
-Examples:
-
- draklive --config config/live.cfg --clean
-
- draklive --config config/live.cfg --all
-
- draklive --config config/live.cfg --record --device /dev/sdb1
-
-=head1 OPTIONS

-
-=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:
-
- {
- system => {
- root => '/chroot/live-move',
- repository => '/mnt/ken/2006.0/i586',
- 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',
- },
- extra_media => [
- {
- storage => 'usb',
- },
- ],
- mount => $predefined{mounts}{squash_union}
- };

-=head1 DESCRIPTION
-
-B<draklive> builds a live distribution according to a
-configuration file, creates a master image,
-and optionnally installs it on a device.
