NAME

       bootcdwrite.conf - configuration file for bootcdwrite

DESCRIPTION

       The  file bootcdwrite.conf contains configuration option for the bootcdwrite(1) program of
       the same named package. The file must be located in the configuration directory  which  is
       usually /etc/bootcd.

       Blank  lines are ignored and lines with leading # are comments. Values have to be set with
       name=value

FORMAT

       SRCDISK="<path>"
              Define the filesystems root directory from which to build an image. If you want  to
              build bootcd from a remote system, export root-directory with nfs, mount it locally
              and add SRCDISK=<mountpoint>.
                Default is "/"

       KERNEL="<path>"
              Define the path to the kernel which should be used. (SRCDISK will be  automatically
              added to path if path does not start with "/" !)
                Default is "vmlinuz"

       KERNEL<number>="<path>"
              You can define multiple additional kernels with <number>. The numbers have to start
              with 1 and can continue with 2, 3, 4 ....  The syntax is as  defined  in  KERNEL  A
              label  for  KERNEL<number>  can  e  defined  with  KLABEL<number>  the  default  is
              KLABEL<number>=linux<number>

       INITRD="<path>"
              Recent official debian kernel images (2.4.x) have started installing initrd images.
              If  you  want to use such a kernel to build a bootcd without recompiling the kernel
              you have to use an initrd image and add it here.  (SRCDISK  will  be  automatically
              added to path of INITRD if it does not start with "/" !)
                The  installed initrd image used to boot from hard disk does not always work from
              cdrom and miss some drivers and features  you  need  for  bootcd.  If  CDDEV="auto"
              should  be  used,  you have to build a new initrd. Install bootcd-mkinitramfs to do
              so.
                Default is "initrd.img"

       INITRD<number>="<path>"
              If KERNEL<number> is defined an initrd for this kernel can be defined here.

       RAMDISK_SIZE=<number in kByte>
              Two Ramdisks ram1 and ram2 will be created, with the following directories:
                 ram1: /dev /etc /home /root /tmp
                 ram2: /var

              Both Ramdisks have the same size which is defined by RAMDISK_SIZE.
                Default is 16384

       TYP="<CD|DVD>"
              Define TYP=CD or TYP=DVD if you want to get a warning if the size of the image will
              be  larger  as  a  CD  or DVD. The CD or DVD itself will no longer be automatically
              burned by bootcdwrite. Only the iso image will be created.
                Default is "CD"

       CDDEV="<auto|device> [...]">
              You can specify one or more CD devices to boot from and/or auto. The first entry is
              the  default,  the  others  will be given as boot options to the user. See DISPLAY.
              Devices are separated by spaces. If you use INITRD and you have installed installed
              bootcd-mkinitramfs you can use "auto" to try to find the bootcd on all SCSI and IDE
              CDROMS automatically.
                Default is "auto /dev/hda /dev/hdb /dev/hdc /dev/hdd /dev/r0 /dev/sr1"

       DISPLAY[<number>]="<file>"
              Define the text to display at boot time (see syslinux doku).  At boot time you  can
              press  Function  Keys  to  see  the  text files. (F1 = DISPLAY, F2 = DISPLAY2, F3 =
              DISPLAY3 ...)
                Default for DISPLAY is "/usr/share/bootcd/default.txt"
                The word kernelinfo will be replaced with a file which includes some  kernelinfo.
              F10 lists all people mentioned in changelog.gz.

       DO_CHECK="<yes|no>"
              To  check  for  possible problems can take a long time, but it is recommended to do
              the checks.
                Default="yes"

       APPEND="<kernel parameter>"
              If you need kernel options other than  "root=..." see append in lilo.conf(5).
                Default is ""

       APPEND<number>="<kernel parameter>"
              If KERNEL<number> is defined kernel parameters for this kernel can be defined here.

       NOT_TO_CD=""
              Add directories which should be excluded from bootcd. Directories are separated  by
              spaces.  (SRCDISK will be automatically added to each path that does not start with
              "/" !).
                Default is ""

       NOT_TO_RAM=""
              When you boot from CD parts of the CD will be copied to ram. Here you  can  decide,
              what should not go to ram. The directories /etc /var /dev /tmp /home and /root will
              be in RAM because they have to be writable. Directories are separated by spaces.
                On CD this dirs will get different names (/etc.ro, /var.ro, ...) but you  do  not
              have to use those different names in NOT_TO_RAM any more !!!
                If you exclude files in NOT_TO_RAM, they will be copied to CD and you will find a
              symbolic link instead of the file in RAM pointing to the file on CD. (SRCDISK  will
              be automatically added to each path that does not start with "/" !).
                Because  most  people's home and root directories are to large to include in RAM,
              subdirectories can be excluded with the default setting.  Default is
                "$(find $SRCDISK/home $SRCDISK/root -maxdepth 1 -mindepth 1 -type d)"

       SSHOSTKEY="<yes|no>"
              If you are using ssh it is helpful to have a unique ssh hostkey for each  CD.  This
              will be generated at burntime with SSHHOSTKEY="<yes>".
                Default is "no"

       UDEV_FIXNET=<yes|no>
              If  you  are  using  the  udev  filesystem  and  want to install the image on other
              machines, you need to  set  this  to  "yes"  because  the  network  interfaces  are
              hardwired    in    /etc/udev/rules.d/z25_persistent-net.rules    (etch)    or    in
              /etc/udev/rules.d/70-persistent-net.rules (lenny) and we must remove them.
                Default is "no"

       ERRORLOG="<file>"
              All errors would be logged to this location.
                Default is "/var/log/bootcdwrite.log"

       VAR="<path>"
              The ISO-image is written to this directory.
                Default is "/var/spool/bootcd"

       FLOPPY_RUNTIME_DEV="<floppy device>"
              When you boot from cd bootcd can read changes from this device, e.g. /dev/fd0.
                Default is ""

       BOOTFLOPPY="<yes|no>"
              If you want to boot from FLOPPY  specify  BOOTFLOPPY=yes.  This  reduces  space  on
              floppy  used  by  bootcdflopcp.  For  this  to  work  FLOPPY_CREATE_DEV  has  to be
              specified.
                Default is also "no"

       BOOT_ONLY_WITH_FLOPPY="<yes|no>"
              If you want to boot several machines  from  the  same  cdrom,  you  must  have  the
              individual  configuration  (exp: /etc/network/interfaces) on floppy. If one can not
              be mounted it is a good idea to stop booting and to  wait  for  manual  interaction
              instead of coming up with a wrong configuration.
                Default is "no"

       CLEAN_VAR="<yes|no>"
              Cached files in /var will be deleted, before /var will be copied to bootcd, if this
              parameter is set. This will minimize needed space on CD.  At  this  time  only  the
              following command will be executed: apt-get clean.
                Default is "yes"

       FASTBOOT="<yes|no>"
              If  is  set  additional  images  for the ramdisk will be created by bootcdwrite and
              copied to CD. This allows faster booting, but needs extra space on CD.
                Default is "yes"

       DEVFS="<yes|no>"
              With devfs you do not need device files and inodes in /dev/*. If  running  diskless
              this  will save some ram (See /usr/src/linux/Documentation/filesystems/devfs/README
              for more infos). It is probably better not to use this feature in  future,  because
              it will be obsolete in newer kernels.
                Default is "no"

       TO_FSTAB="<fstab entry>"
              Add  additional  mount  point  entries to the cdrom's /etc/fstab. If you don't want
              additional mount points, leave it as "".
                e.g.: TO_FSTAB="/dev/hdc1 /home ext3 defaults 1 1"
                Default is ""

       NOTCOMPRESSED="<list of files and directories>"
              Files or Directory-Trees that should never be compressed on CD can be listed  here.
              This  is  useful  for  documentation which should be visible without installing the
              bootcd-image.
                Define the path as it is on the CD, (with /var.ro instead of /var)  and  separate
              files and directories with spaces.
                Default is ""

       DISABLE_CRON="<list of files>"
              Files  listed  will  be  on  the cdrom with a .no_run_on_bootcd suffix so run-parts
              won't execute them. The original file will be a link to /bin/true.  This  is  meant
              for cron maintenance scripts which are useless on a static cdrom. The default is to
              disable the daily find, standard and security scripts. With bootcd2disk this  files
              will  be  reactivated  again.  (SRCDISK will be automatically added to path if path
              does not start with "/" !)
                Default is "etc/cron.daily/find etc/cron.daily/standard etc/cron.daily/security"

       BOOTCDMODPROBE="<standard|bootcd|auto>"
              This option is only relevant, if bootcd-mkinitramfs is installed.  If  booted  from
              initrd,  bootcd  has  to  load  the necessary modules.  If only modules provided by
              initramfs-tools are needed you can specify "standard" here.  If bootcd  should  try
              extra  hard  to  load necessary modules you can specify "bootcd" here.  Bootcd will
              use discover for this purpose. So discover has to be  installed.   If  you  specify
              "auto",   bootcd  will  check  if  discover  is  installed.   If  it  is  installed
              "BOOTCDMODPROBE=bootcd" will be set, if not "BOOTCDMODPROBE=standard" will be  set.
              Be  aware  that  people have reported, that sometimes BOOTCDMODPROBE=bootcd may not
              work but sometimes it is needed.  Default is "standard"

       MKISOFS_CHNG="<option>"
              Add some additional options to mkisofs on  creating  cdimage.  Possible  syntax  is
              MKISOFS_CHNG="[[!]<option>...]".
                Most  people  will  probably define "", but it was reported that you may need the
              following option with newer hardware "-boot-load-size 20".

              Please create debian-bugreports if you have to use special options,  not  mentioned
              here. Then I can list this options here!

              Example: MKISOFS_CHNG="-opt1 -opt2 <value> !-opt3"
               means: use "-opt1" and "-opt2 <value>", don't use any
                      previous "-opt1 [<value>...]", "-opt2 [<value>...]" and
                      "-opt3 [<value>...]".
                      Leave any other options as defined.

       function extra_changes() {
              return }
              It  is  possible  to  define  a  function  called  extra_changes to have some files
              modified on the ISO image.

              Example:
                function extra_changes() {
                   echo "noname" >$VAR/changes/etc.ro/hostname
                }

              Optional
