NAME

       bootcd2disk - copy a system running from bootcd to a disk

SYNOPSIS

       bootcd2disk [-i|-s|-m] [-d debug_runtime_config] -- [-h|--help]
              [-c|--conf   CONF]   [-y|--yes]   [-url  url]  [--only_mount]  [--only_unmount]  [--only_copydata]
              [-o|--use_originaldiskname] [-z|--zerodsk] [--variable_from_bootcd2disk.conf(5) value]

DESCRIPTION

       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.

OPTIONS

       -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:

              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

       -z
          This  option  can be used to zero the first part of the disk, that contains the MBR, before writing to
          it.  Normally this should not be necessary, because sfdisk should be able to rewrite a previously used
          disk.  But users of bootcd have seen disks, where this option may help.

       -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 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  --COPYDEST
          COPYDEST

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

       --variable_from_bootcd2disk.conf(5) value
          variables or functions 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 VALUE
