21 beyerle@PS 68 
    Installes LiveCD on PARTITION and the boot loader grub

    into the Master Boot Record (MBR) of DEVICE.

  Example:
81 
 
82 
  $SCRIPTNAME -swap /dev/sda3 -mbr /dev/sda /dev/sda2
83 
 
84 
    Will install LiveCD on /dev/sda2 (= second partition on
85 
    first SATA disk). All data on /dev/sda2 will be deleted.
86 
    /dev/sda3 has to be a Linux Swap partion. GRUB will be
