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
