salut ,
je suis nouveau et j’orais besion de votre aide.
je vous explique 
je voudrais fair un live cd de ma debian lenny avec bootcd , j’ai donc modifier le bootcdwrite.conf comme ceci :
[quote]#
bootcdwrite.conf
look for man bootcdwrite.conf(5) for more informations
this path was added as prefix to KERNEL, INITRD, DISABLE_CRON, NOT_TO_CD
and NOT_TO_RAM, if this are relativ paths (without starting “/”)
SRCDISK=/
Define the kernel which is used
KERNEL="/boot/vmlinuz-2.6.26-2-686"
additional options for the kernel
APPEND=""
path to initrd
INITRD="/boot/initrd.img-2.6.26-2-686"
define multiple kernels with KERNEL and label KLABEL
default label is "linux
KLABEL1=686-3
KERNEL1=/boot/vmlinuz-2.6.18-3-686-bigmem
INITRD1=/boot/initrd.img-2.6.18-3-686-bigmem
APPEND1=
Text to Display at Boottime (see syslinux doku)
This option is not supported for hppa
display info files on boot prompt (F1 = DISPLAY, F2 = DISPLAY2 …)
(kernelinfo is replaced with a file which includes the kernelinfo)
DISPLAY="/usr/share/bootcd/default.txt"
DISPLAY2=“kernelinfo”
size of each ramdisk ram1 and ram2 (ram1: /dev /etc /home /root /tmp,
(ram2: /var)
RAMDISK_SIZE=16384
typ is CD or DVD
TYP=DVD
specify one or more CD devices to boot from, first is default
“auto” try to find the bootcd on all SCSI and IDE CDROMS
CDDEV=“auto /dev/sda1 /dev/hda /dev/hdb /dev/hdc /dev/hdd /dev/scd0 /dev/scd1”
do some checks or not
DO_CHECK=yes
exclude some files or directories from writing to cd
NOT_TO_CD="/home/soogri/Téléchargements/ /home/soogri/ISO/"
exclude some files or directories from loading to ram
Because most people’s home and root dir are to large to include
in RAM, subdirectories can be excluded:
NOT_TO_RAM="$(find $SRCDISK/home $SRCDISK/root -maxdepth 1 -mindepth 1 -type d)"
If you are using ssh it is helpful to have a unique ssh hostkey for
each CD.
SSHHOSTKEY=yes
If you are using udev filesystem and install the image only 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. You can do this also on bootcd2disk.
UDEV_FIXNET=“yes”
logfile
ERRLOG=/var/log/bootcdwrite.log
where the image resists after build
VAR=/var/spool/bootcd
FLOPPY_RUNTIME_DEV=|""
When you boot from cd you read changes from this device.
FLOPPY_RUNTIME_DEV=/dev/fd0
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:
BOOTFLOPPY=no
BOOTFLOPPY=no
If you want to boot several machines from the same cdrom, you must have
the individual configuartion (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 comming up with a wrong configuration.
BOOT_ONLY_WITH_FLOPPY=no
delete some chached files in /var
CLEAN_VAR=yes
If FASTBOOT=yes then additional images for the ramdisk will be created
by bootcdwrite and copied to CD. This allows faster booting,
but needs extra space on CD
FASTBOOT=yes
use isolinux (yes,no,auto), auto check for isolinux and use it
ISOLINUX=auto
use -s (save, slow, stupid) option on syslinux
SYSLINUX_SAVE=yes
choose the architecture
ARCH=auto|hppa|i386|ia64
ARCH=auto
use devfs or not
DEVFS=no
addiditionel entries to fstab
TO_FSTAB="/dev/hdc1 /home ext3 defaults 1 1
/dev/usb0 /mnt/usb ext3 defaults 1 1 "
TO_FSTAB=""
transparent compression of ISO 9660/Rock Ridge filessytem
(“auto” checks for space to compress the image on the local system)
COMPRESS=<yes|no|auto>
COMPRESS=“auto”
Files or Directory-Trees that should never be compressed on CD can be listed
here. You have to define the Path as it is on the CD, (with /var.ro
instead of /var)
NOTCOMPRESSED=""
Files listed in DISABLE_CRON 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.
DISABLE_CRON=“etc/cron.daily/find etc/cron.daily/standard etc/cron.daily/security”
With this variable you can add or delete some options
given to mkisofs by bootcdwrite.
Please create debian-bugreports if you have to use special
options, not mentioned here. Then I can list this options here.
MKISOFS_CHNG=""
function extra_changes()
It is possible to define a function called extra_changes to have some
files modified on the ISO image. Here is an example:
function extra_changes() {
echo “noname” >$VAR/changes/etc.ro/hostname
mkdir -p $VAR/changes/etc.ro/network
( echo “auto lo”
echo “iface lo inet loopback”
echo “”
echo “auto eth0”
echo “iface eth0 inet static”
echo " address 0.0.0.0"
echo " netmask 255.255.255.0"
) >$VAR/changes/etc.ro/network/interfaces
echo “127.0.0.1 localhost noname” >$VAR/changes/etc.ro/hosts
cat $SRCDISK/etc/passwd |
grep -v -e “^bs:” -e “^bianca:” -e “^tim:” >$VAR/changes/etc.ro/passwd
cat $SRCDISK/etc/shadow |
grep -v -e “^bs:” -e “^bianca:” -e “^tim:” >$VAR/changes/etc.ro/shadow
cat $SRCDISK/etc/group |
grep -v -e “^bs:” -e “^bianca:” -e “^tim:” >$VAR/changes/etc.ro/group
}
BOOTCDMODPROBE=standard|bootcd|auto
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
neccessary 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.
BOOTCDMODPROBE=standard

l’iso se créer rapidement et sans erreur ( cdimage.iso = 6Go~), je tente donc de le virtualisé ( avec virtualbox ) ,aux boot il me demande je ne sait trop quoi du genre “boot :”
je tape sda1, j’aperçois “Probing EDD (edd=off to disable)… ok” lors du defilement du texte ( je ne sait pas si c’est normal ) puis j’ai un beau :
[quote]mounting root file system … /init: line 172: syntax error: 0xauto
kernel panic not syncing vfs unable to mount root fs on unknown-block 0 0[/quote]
Pourquoi j’ai cette erreur ? J’ai oublié de mettre quelque chose dans mon bootcdwrite.conf ?
merci d’avance pour votre aide
