Unable to boot LFS... Kernel Panic - not syncing


Hi all

i have succesfully installed LFS 6.3 and was able to boot into it when my host system was BOSS(Bharat operating system solutions - debian based system) ...

now i have installed debian 4.0 etch in the place of BOSS...and added the LFS option to the boot loader....when i tried to boot LFS iam getting the following error...

Code:
Freeing unused kernel memory: 296k freed
Warning: unable to open an initial console
Failed to execute 1. Attempting defaults...
Kernel panic - not syncing : No init found. Try passing init= option
to kernel.
Please see this link in which screen capture of the error is given...

http://www.zshare.net/image/103829355a6b3a62/

I have tried giving the option init=1 to the kernel parameters....but no use..i also tried re installing the kernel...(last step of LFS...)
Still i am getting same error ...

Please help me to resolve this as soon as possible

THANKS IN ADVANCE

init= needs to point to a valid program that can start up the system like /sbin/init or you can point to a script or you can point to a shell.

Thanks for your reply..

I have tried giving the option init=/sbin/init to the kernel parameters... i have also tried init=/bin/bash ..
but i am getting the same error with one more line before kernel panic

Code:
Freeing unused kernel memory: 296k freed
Warning: unable to open an initial console
Failed to execute /sbin/init . Attempting defaults...
Kernel panic - not syncing : No init found. Try passing init= option
to kernel.
Code:
Note :

I was able to boot the same when i was using BOSS(host system using which i have built LFS...)
Now i have installed another OS...Debian 4.0 etch in place of BOSS....

It is not booting after installing Debian...What has been affected due to installation...
it  was fine before installation of debian...


Please help me to boot LFS...

Thanks in advance

Yes it is possible, you could also squash fs it to make it smaller. To run on usb you may have to consider redesigning your startup scripts to operate in a read-only setup.
