custom linux problem with init

[TomasD]

Hi,
I'm trying to build minimal single user linux and run it on my usb key. I created 1 bootable partition, created ext2 filesystem, installed grub and copied /dev directory from my other linux box. Having filesystem with following directories:
boot
dev
lost+found

I have compilied 2.6.28.4 linux with default selections that are present on make menuconfig only removing options for initrd and loadable module support, hoping that all modules required to mount root partition on usb key will be compiled in.

My menu.lst below:
title Linux
root (hd0,0)
kernel /boot/vmlinuz-2.6.28.4 rootdelay=10 root=/dev/sda1
boot

I'm getting kernel panic at the init:
VFS: Mounted root (ext2 filesystem) readonly
Freeing unused kernel memory: 460k freed
Kernel panic - not syncing: No init found. Try passing init= option to kernel

So I've copied /bin/sh to my usb /bin/sh and added init=/bin/sh to kernel line in grub's menu.lst, still getting a kernel panic:
VFS: Mounted root (ext2 filesystem) readonly
Freeing unused kernel memory: 460k freed
Failed to execute /bin/sh. Attempting defaults...
Kernel panic - not syncing: No init found. Try passing init= option to kernel

Can anyone please help me to get to single user mode?

Cheers,
Tomas

sorted out. I had no /lib directory ldd /bin/bash showed that I'm missing some libraries, tested running
chroot /media/disk /bin/bash worked also worked as init.
