       bootcd2disk - copy a system running from bootcd to a disk

       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 backup 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.


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

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


          print help and exit

          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.

          answer always yes

       -url url
          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

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

              bootcd2disk -url

          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

          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

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

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

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

          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 bash bootcd2disk -p ....

          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: --VARIABLE

       --function_from_bootcd2disk.conf(5) definition
          functions  listed  in  bootcd2disk.conf(5)  can  be  overwritten from command line. For
          example a function fun() { echo "hello world"; } could  be  defined  with  the  option:
          --fun 'fun() { echo "hello world"; }'

          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.


       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.

          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.
