[Lug-bg] bootcd problem

[Georgi <georgiev@xxxxxxxxxx>]

Здравейте група,
От два дни се опитвам да си направя LiveCD  с bootcd по начина описан в 
http://www.debian-administration.org/articles/148
За сега неуспешно. При опит за зареждане от направеното Live CD 
получавам съобщение :
Kernel panic - not syncing : VFS : Unable to mount root  fs  on 
unknown-block(1,0)
Търсенето в google не даде разбираем за мен резултат.

Системата ми е Debian  инсталирана от  Knoppix  върху виртуална машина  
VMWare.
Ядрото е 2.6.11.

Прилагам конфигурационния файл.

Предполагам, че причината е в
APPEND="root=/dev/ram" , което добавих в конфигурационния файл.
Преди да го добавя  съобщението гласеше, че не намира валидна стойност 
за  root= ...
От тук си правя извода, че трябва да има  root=.... , но не знам коя е 
правилната стойност.
Надявам се да получа някоя полезна идея.

# If you want to boot from FLOPPY specify BOOTFLOPPY=yes. This reduces

# 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.

# 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 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 necessarry 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
