opensuse kernel panic

Hi,
I do not maintain the system that is having problem but I have been asked for help and I am trying to understand what the possible solution to their boot problem is.

Basically when they boot the OS via Grub, kernel loads and mounts soft-raid volume in rw mode and panics throwing a message.
Code:

/bin/run-init: /sbin/init: no such file or directory

I tried choosing failsafe, xen and desktop(default) entries in Grub but all end up kernel panic and same message as above.

I have booted the system with Sysrescue cd. Good thing it detected the soft raid volume and showed that in fdisk o/p. I am also able to mount the /dev/md0(sof raid 1) to a directory in /mnt/

Code:

mount -t ext4 /dev/md0 /mnt/backup
chroot fails
Code:

root@sysresccd /root % cd /mnt/backup
root@sysresccd /mnt/backup % chroot /mnt/backup
chroot: failed to run command ‘/bin/zsh’: No such file or directory

root@sysresccd /mnt/backup % ls -al
Code:

Code:

openSUSE 11.2 (x86_64)
VERSION = 11.2

I don't see '/bin' directory in the root directory of mounted raid volume.

Can anyone throw some light or suggest best solution if they have encountered this before?

Thank you!
