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]

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
