NAME
bootcdwrite.conf - configuration file for bootcdwrite
DESCRIPTION
The file bootcdwrite.conf contains configuration option for the bootcd‐
write(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"
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"
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/scd0
/dev/scd1"
DISPLAY="<file>"
Define the text to display at boot time (see syslinux doku),
this option is not supported for hppa.
Default is "/usr/share/bootcd/default.txt"
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=..." and
"ramdisk_size=..." see append in lilo.conf(5).
Default is ""
NOT_TO_CD=""
Add directories which should be excluded from bootcd. Directo‐
ries 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 SSH‐
HOSTKEY="<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 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. For hppa this option is
not supported and must be set to no!
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/inter‐
faces) on floppy. If one can not be mounted it is a good idea to
stop booting and to wait for manual interaction instead of com‐
ing 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"
ISOLINUX="<auto|yes|no>"
If syslinux is recent enough then isolinux can be used instead
of syslinux and ISOLINUX=auto will be treated as ISOLINUX=yes.
If you want to use syslinux instead you have to use ISOLINUX=no.
(See also /usr/share/doc/syslinux/isolinux.doc.gz.)
Default is "auto"
SYSLINUX_SAVE="<yes|no>"
This option for ISOLINUX. If SYSLINUX_SAVE=yes then syslinux is
called with -s option. The manpage of syslinux says: this
installs a "save, slow and stupid" version of syslinux. In ear‐
lier version the -s option was always used. Now you can change
it.
Default is "yes"
ARCH="<auto|hppa|i386|ia64>"
You can create bootcd for HP PA-RISC too. It is possible to let
bootcdwrite detect your architecture with ARCH=auto. To use
ARCH=hppa the debian package bootcd-hppa must be installed.
Default is "auto"
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 ""
COMPRESS="<auto|yes|no>"
If you want to have a transparent-compression ISO 9660/Rock
Ridge filesystem define "yes". Use "auto" if you want compres‐
sion and bootcdwrite should check the needed disk space and
check for the necessary software is installed. Therefore you
have to define DO_CHECK=yes if you define COMPRESS=auto.
Default is "auto"
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 suf‐
fix 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 automat‐
ically 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 neces‐
sary 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 "BOOTCDMOD‐
PROBE=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. Pos‐
sible 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
