busybox cause some problem...


There's an old ramdisk with busybox.
Because i would like to add new functions in it (telnetd , tab completion...),
so i re-compile busybox and override install to the old one.

But after booting , error message shows...

nit started: BusyBox v1.14.3 (2009-08-11 22:32:23 CST)
Bad inittab entry at line 5

As for my /etc/inittab file is...

# /etc/inittab: init(8) configuration.
# $Id: inittab,v 1.91 2002/01/25 13:35:21 miquels Exp $

# The default runlevel.
id:3:initdefault:

# Boot-time system configuration/initialization script.
# This is run first except when booting in emergency (-b) mode.
si::sysinit:/etc/init.d/rcS

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

# /etc/init.d executes the S and K scripts upon change
# of runlevel.
#
# Runlevel 0 is halt.
# Runlevel 1 is single-user.
# Runlevels 2-5 are multi-user.
# Runlevel 6 is reboot.

# Action on special keypress (ALT-UpArrow).
#kb::kbrequest:/bin/echo "Keyboard Request--edit /etc/inittab to let this work."

# What to do when the power fails/returns.
pf:owerwait:/etc/init.d/powerfail start
pn:owerfailnow:/etc/init.d/powerfail now
po:owerokwait:/etc/init.d/powerfail stop

# This line provides a nice out-of-box experience. For regular use, you
# should replace it with the proper getty lines below.
con:2345:respawn:/sbin/getty console



Do i miss something???

===
Someone says , remove init=linuxrc in booting argument could solve this.
But...I always don't have this argument!

Busybox doesn't support runlevels. You can't use your standard Linux inittab (as this one seems to be copied from your Linux machine). Example busybox file:
