busybox cannot open a shell

[marco]

hi, every one,
	i use busybox-1.2.1, and i use initrd startup, the content of linuxrc is:

    /bin/echo "start /sbin/init"
    exec /sbin/init

	and the content of inittab is :
	::sysinit:/etc/init.d/rcS
	::respawn:-/bin/sh

	and the content of rcS is   :
#! /bin/sh
PATH=/bin:/sbin:/usr/bin:/usr/sbin
export	PATH

/bin/echo "mount other filesystems..."
/bin/mount -a

/bin/echo "hostname eb2410"
/bin/hostname eb2410

so i start kernel and initrd, but it cannot go into shell, just stop here:
Mounted devfs on /dev
start /sbin/init
init started:  BusyBox v1.2.1 (2006.09.26-04:17+0000) multi-call binary
Starting pid 666, console /dev/tts/0: '/etc/init.d/rcS'
mount other filesystems...
hostname eb2410

why ? why cannot open a shell?
please help me !
