NAME

       bootcdwrite - build a bootable iso image from a running system

SYNOPSIS

       bootcdwrite [-i|-s|-m] [-d debug_runtime_config] -- [-h|--help]
              [-c|--conf     CONF]    [--only_floppy]    [-y|--yes]    [--mokcrtder    MOKCRTDER]
              [--variable_from_bootcdwrite.conf(5)  value]   [--function_from_bootcdwrite.conf(5)
              definition]

DESCRIPTION

       bootcdwrite is used to write a Linux Installation to an iso image.  It is possible to copy
       a system mounted per NFS to a local iso.  The iso can be  copied  to  a  CD  or  DVD  with
       standard tools.

       It is important that the kernel can access the cdrom on the system, where you want to boot
       from the CD, without having to load any modules. (Because to load  modules  from  CD,  the
       kernel  must have access to CD before). If this is not the case you have first to create a
       new kernel with CD-support built in.

       If something goes wrong with bootcdwrite, the user will be given the chance to correct the
       problem.  bootcdwrite  starts many commands. If a command exits with an exit code != 0, or
       if a command produces unknown output on stdout or stderr, the command and the output  will
       be  shown to the user.  He gets the option to exit, retry the failed command, or to ignore
       the failed command.

OPTIONS

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

       -d debug_runtime_config
          Run bootcdwrite in 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/bootcdwrite.conf

       -h|--help
          print help and exit

       --only_floppy
          only a bootfloppy (to boot an existing bootcd) has to be created.

       -y|--yes
          answer always yes

       --mokcrtder MOKCRTDER
          If  an  own  Machine  Owner Key (MOK) is needed to boot the created bootcd, with secure
          boot enabled, this option  can  install  the  public  MOK  Certificate  in  DER  format
          (MOKCRTDER)  to  the  EFI  partition  of the bootcd, to be loaded manually in BIOS. See
          <https://wiki.debian.org/SecureBoot> .

          If secure boot is not used, or if a standard Debian signed Kernel is used on  a  system
          with  the  standard  Microsoft  Platform  Key (PK) installed in BIOS this option is not
          needed.

       --variable_from_bootcdwrite.conf(5) value
          variables or functions listed in bootcdwrite.conf(5) can be  overwritten  from  command
          line.  For example a variable called VARIABLE will get the value VALUE with the option:
          --VARIABLE VALUE

       --function_from_bootcd2disk.conf(5) definition
          functions listed in bootcdwrite.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"; }'
