Use ldd to find the required libraries for an application. For busybox, they're:

/lib/libcrypt.so.1 (symlink to /lib/libcrypt-2.5.so)
/lib/libc.so.6 (symlink to /lib/libc-2.5.so)
/lib/ld-linux.so.3 (symlink to /lib/ld-2.5.so)

You'll probably also need to bind mount /dev, /proc and /sys under your chroot:

Code:

mkdir /tmp/disk/dev /tmp/disk/sys /tmp/disk/proc
mount -o bind /dev /tmp/disk/dev
mount -o bind /sys /tmp/disk/sys
mount -o bind /proc /tmp/disk/proc

As for why you get the error message you get - it's a bit confusing, but actually correct. It cannot execute /bin/sh because the linked libraries don't exist.
