[gentoo-embedded] login issues with busybox

[Morgan, Austin D.]

I am using busybox for an embedded system.  I have an issue I have never
seen before and was hoping someone might be able to shine a little light on
it.  I am using and initramfs with /init as a simlink to /bin/busybox, my
/etc/inittab looks like this:
# /etc/inittab
#
# Copyright (C) 2001 Erik Andersen <andersen@codepoet.org>
#
# Note: BusyBox init doesn't support runlevels.  The runlevels field is
# completely ignored by BusyBox init. If you want runlevels, use
# sysvinit.
#
# Format for each entry: <id>:<runlevels>:<action>:<process>
#
# id        == tty to run on, or empty for /dev/console
# runlevels == ignored
# action    == one of sysinit, respawn, askfirst, wait, and once
# process   == program to run

# Startup the system
null::sysinit:/bin/mount -o remount,rw /
null::sysinit:/bin/mount -a
null::sysinit:/bin/hostname -F /etc/hostname
null::sysinit:/sbin/ifconfig lo 127.0.0.1 up
null::sysinit:/sbin/route add -net 127.0.0.0 netmask 255.0.0.0 lo

# now run any rc scripts
null::sysinit:/etc/init.d/rcS

# Set up a couple of getty's
tty1::respawn:/sbin/getty 38400 tty1
tty2::respawn:/sbin/getty 38400 tty2

# Put a getty on the serial port
ttyS0::respawn:/sbin/getty -L ttyS0 9600 vt100
ttyS1::respawn:/sbin/getty -L ttyS1 9600 vt100

# Logging junk
null::sysinit:/bin/touch /var/log/messages
null::respawn:/sbin/syslogd -n -m 0 -s 800 -b 3 -L
null::respawn:/sbin/klogd -n
tty3::respawn:/bin/tail -f /var/log/messages

# FTP is here because we want it to restart if it ever crashes
# null::respawn:/usr/sbin/vsftpd /etc/vsftpd/vsftpd.conf

# Stuff to do for the 3-finger salute
::ctrlaltdel:/sbin/reboot

# Stuff to do before rebooting
null::shutdown:/etc/init.d/rcK
null::shutdown:/usr/bin/killall klogd
null::shutdown:/usr/bin/killall syslogd
null::shutdown:/bin/umount -a -r
null::shutdown:/sbin/swapoff -a

When the system comes up everything looks normal.  I have an login: prompt
on the screen.  When I try to login I get the message:
login: This applet requires root priviledges!

On tty3 I see that it is logged that the getty exits and restarts.

Anyone seen something similar?

check your suid settings

for more information, read the help text in the busybox configuration menu 
under the suid stuff

this may help as well
