bootcd2disk  is used to write a running system to disk.  It was originally used do write a running bootcd
       built with bootcdwrite to disk, but it is also possible to write a system directly to an attached disk.

       The system can be copied to one or more disk partitions seen by the running system.   When  running  from
       bootcd,  it  is possible to let bootcd2disk automatically find a disk, make partitions on it, copy the cd
       to the disk and make the disk bootable.

       All variables, that can be given as OPTIONS or in the bootcd2disk.conf  file,  will  not  be  taken  form
       Environment variables.

       Only the following variables will be set as Environment variables.

       LUKS_PASSWD
          This  variable contains the luks passphrase. It is used to initialize luks partitions and to open luks
          partitions. If this variable is not  set  in  the  envrionment  it  will  be  asked  interactively  by
          bootcd2disk if needed.

-i|-s|-m|-ddebug_runtime_config
          Run bootcdwrite in interactive, silent, minimal control  or  debug  mode.   See  shellia(1)  for  this
          standard shellia options.

       -c|--confCONF
          use the bootcdwrite config options from file CONF.  Default:

              CONF=/etc/bootcd/bootcd2disk.conf

       -h|--help
          print help and exit

       -o|--use_originaldiskname
          if  bootcd2disk.conf  was created by bootcdmk2diskconf, not only the variable DISK0 is defined as auto
          but also ORIG_DISK0 is defined with the original device. To use it this option exists.

       -y|--yes
          answer always yes

       -urlurl
          If bootcd2disk is slow on your system (because of a slow  CD/DVD  drive  or  the  HP  ILO  virtual  CD
          interface),  you  can use an image server to get the bootcd iso image from.  The swap partition of the
          installed system will be used as temporary space for the iso image.

          The image server url is configured with this option.  Example:

              bootcd2disk -url http://192.168.1.1/cdimage.iso

          Another way the increase the performance is the use  of  the  mounted  CD/DVD  itself  for  the  copy.
          Example:

              bootcd2disk -url file:///dev/sdc0

          The swap partition of the upcoming system must have enough space to get the whole image!

       --only_mount
          After bootcd2disk did partition, format and install the disk, the disks can be mounted again with this
          option.  For example to run update-grub in chroot on the mounted disk:
              # remount disks to /mnt/bootcd.disc/ bootcd2disk --only_mount

              #  prepare  chroot mount --bind /dev /mnt/bootcd.disc/dev mount -t proc none /mnt/bootcd.disc/proc
              mount -t sysfs none /mnt/bootcd.disc/sys mount -t devpts none /mnt/bootcd.disc/dev/pts

              # run update-grub in chroot chroot /mnt/bootcd.disc update-grub

       --only_unmount
          If the disks are mounted with option --only_mount , they can be unmounted with this option.

       --only_copydata
          This will not create partitions, but only copy data to the directory COPYDEST defined with  --COPYDESTCOPYDEST. Filesystems have to be mounted before.  The Bootloader will not be activated.

       -p|--only_print_options
          Print the options calculated from defaults, config-file and commandline and exit.

          Hint:  This  option may display more information about defined functions in a non-bash environment, if
          calling bashbootcd2disk-p....

       -z|--zerodsk
          This option writes zeros to the beginning of a disk before using it.

       --variable_from_bootcd2disk.conf(5)value
          variables listed in bootcd2disk.conf(5) can be overwritten from command line. For example  a  variable
          called VARIABLE will get the value VALUE with the option: --VARIABLEVALUE--function_from_bootcd2disk.conf(5)definition
          functions  listed  in bootcd2disk.conf(5) can be overwritten from command line. For example a function
          fun(){echo"helloworld";} could be defined with the option: --fun'fun(){echo"helloworld";}'--only_sync
          To use this option, bootcd2disk should have been  run  before,  because  the  target  disk  should  be
          partitioned  and  formatted  already.   With  ---only_sync only the steps needed to sync will be done.
          That means the target disc will be mounted, the files will be synced, the bootloader will be activated
          and the target disk will be unmounted.
