[=?gb2312?B?s8LPow==?=]

Hi, 
	I use ash as the default shell. Ln -s busybox sh   ln -s busybox ash
In /etc/shells
/bin/sh
/bin/ash

These are  some important set up in inittab,I use sysvinit instead of
busybox init
Id:3:initdefault:
Si::sysinit:/etc/init.d/rcS

# What to do in single-user mode.
~~:S:wait:/sbin/sulogin

l0:0:wait:/etc/init.d/rc 0
l1:1:wait:/etc/init.d/rc 1
l2:2:wait:/etc/init.d/rc 2
l3:3:wait:/etc/init.d/rc 3
l4:4:wait:/etc/init.d/rc 4
l5:5:wait:/etc/init.d/rc 5
l6:6:wait:/etc/init.d/rc 6
# Normally not reached, but fallthrough in case of emergency.
z6:6:respawn:/sbin/sulogin

T0:234:respawn:/sbin/getty -L ttyS0 115200 vt100  -------------->my board is
mpc885 I use serial as the console
