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, no_initrd => 0, }, 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).
