       fai-cd - make a bootable CD-ROM or USB stick that performs an FAI


       fai-cd [OPTION] -m MIRROR ISOFILE
       fai-cd [OPTION] -B FILE
       fai-cd [OPTION] -d URL
       fai-cd [OPTION] -S IMAGEFILE


       This  command  creates  a  bootable  ISO CD-ROM image that performs the
       fully automatic installation from CD-ROM without an install server. The
       ISO  image  will  be  written to FILE. To create the image, the command
       needs the NFSROOT, the configuration space and a partial mirror,  which
       is  created  by  fai-mirror.  The  ISO  image will contain a compressed
       squashfs filesystem. This hybrid CD image can also be written to an USB
       stick using dd(1).


       -A     Create  a boot only CD image (also usable for an USB stick) with
              autodiscover function. The CD will scan the  subnet  for  a  FAI
              server.  By  default it shows a menu with all profiles available
              from which you can select a type  of  installation.  This  image
              only  needs  25MB.   You can add the -J option to make the image

       -B     Create a boot only ISO image which does a network  installation.
              It  does  not  include the nfsroot, the partitial mirror and the
              config space; however  for  it  to  automatically  initiate  the
              installation  -d  has  to  be set. By default CONFIG_SRC will be

       -b     After creating the ISO image burn  it  by  calling  wodim(1)  (a
              version of cdrecord).

       -C CFDIR
              Use  CFDIR  as the configuration directory. Default is /etc/fai.
              You can also set the environment variable FAI_ETC_DIR.

       -d URL Set  the  location  of  the  config  space  to  URL  (this  sets
              FAI_CONFIG_SRC).  Set  it to "" to create an ISO image without a
              config space. If not set, the value  of  FAI_CONFIGDIR  will  be
              used.   Currently   no   file:  is  allowed  here,  instead  set
              FAI_CONFIGDIR in fai.conf(5).

       -e     Exclude the directory /var/tmp from the nfsroot. You may put the
              file   base.tar.xz   in   the   configuration   space  into  the
              subdirectory basefiles. This option will save about 50MB of disk
              space.  This  option  will exclude the directory even when -H is

       -f     Force removal of an existing ISO image  before  creating  a  new

       -g FILE
              Use FILE as grub grub.cfg file. The script will look for FILE in
              CFDIR. If FILE is located in another directory then a full  path
              must be specified. If not specified, use /etc/fai/grub.cfg.

       -h     Show simple help and version.

       -H     Do  not  hide  directories. Using this option will consume about
              45MB more disk space on your media. By default, some directories
              like  man  pages and locales are hidden and will not be put onto
              the CD or the USB stick.

       -J     Use xz compression when calling mksquashfs. Default is gzip.

       -M     Do not add the package mirror to the CD.

       -m DIRECTORY
              Use DIRECTORY as partial FAI mirror. This option  is  mandatory,
              unless you use -M or -B.

       -S     Create  a  squashfs  image file, instead of a complete iso. This
              image file can be used to fetch the nfsroot through various ways
              over the network.


       After you've created a mirror with fai-mirror in /media/mirror, you can
       create a CD using:

          # fai-cd -m /media/mirror fai-cd.iso

       If you want to create a bootable USB stick (here /dev/sdf) , write  the
       CD image to the stick via dd(1).

          # dd if=fai-cd.iso of=/dev/sdf bs=1M

       It  is  possible to install over the network without using NFS, i.e. by
       getting the nfsroot via an http request. To do so you have to create  a
       squashfs image using the following command:

          # fai-cd -S squashfs.img

       In  addition  to  that you can create said image without a config space
       and without a mirror. This  is  useful  for  when  you  want  to  avoid
       creating a new image after modifying your config space or updating your

          # fai-cd -d "" -SMeJ squashfs.img

       To fetch the image via http, use  the  following  kernel  command  line


       Create the autodiscover boot image:

          # fai-cd -JAg /etc/fai/grub.cfg.autodiscover fai-autod.iso


       Additional  kernel command line options can be found in the man page of
       dracut.cmdline(7). fai-cd needs enough disk space in  TMPDIR  (/tmp  by
       default) for creating the compressed filesystem. You may want to set it
       to another directories, before calling fai-cd.
