passwd group, what else do I need?

Trying to build a minimum system but can't logon. So I just installed the programs I thought could log me on from chroot
sysvinit bash maybe shadow to confirm anyway heres waht I done

# installing filesystem

cd /mnt/lfs &&
mkdir -p bin boot dev/pts etc/opt home lib mnt proc root sbin tmp var opt &&
for dirname in /mnt/lfs/usr /mnt/lfs/usr/local
mkdir $dirname
cd $dirname
mkdir bin etc include lib sbin share src
ln -s share/man
ln -s share/doc
ln -s share/info
cd $dirname/share
mkdir dict doc info locale man nls misc terminfo zoneinfo
cd $dirname/share/man
mkdir man{1,2,3,4,5,6,7,8}
done &&
cd /mnt/lfs/var &&
mkdir -p lock log mail run spool tmp opt cache lib/misc local &&
cd /mnt/lfs/opt &&
mkdir bin doc include info lib man &&
cd /mnt/lfs/usr &&
ln -s ../var/tmp

cd /mnt/lfs &&
chmod 0750 root &&
chmod 1777 tmp var/tmp

# installing bash

rm -fr /usr/src/bash-2.05b
cd /usr/src
bzcat /mnt/data/new-lfs/src/bash-2.05a.tar.bz2 | tar xv
cd bash-2.05a
./configure --enable-static-link \
--target=i586 --with-curses \
--prefix=/mnt/lfs/usr --bindir=/mnt/lfs/bin
make install

cd /mnt/lfs/bin &&
ln -sf bash sh
rm -fr /usr/src/bash-2.05b

cd /mnt/lfs/bin &&
ln -sf bash sh

# setting up, passwd group files

echo "root::0:0:root:/root:/bin/bash" > /mnt/lfs/etc/passwd

cat > /mnt/lfs/etc/group << "EOF"

# installing sysvinit

rm -fr /usr/src/sysvinit-2.84
cd /usr/src
bzcat /mnt/data/new-lfs/src/sysvinit-2.84.tar.bz2 | tar xv
cd /usr/src/sysvinit-2.84/src/
make -e LDFLAGS=-static
ROOT=/mnt/lfs make install
rm -fr /usr/src/sysvinit-2.83

cd /mnt/lfs/sbin
ln -s agetty getty

So I try to login using sulogin
su login complains about passwd
but lets me login with -e

Entered chroot enviourment

# chroot /mnt/lfs
bash-2.05a# sulogin
sulogin: cannot open password database!
bash-2.05a# sulogin -e

exit chroot enviuorment
Sulogin didn't work first time so tried sulogin -e
gave me a shell. So I thought cool I'm logged in as root so I install shadow with the following

rm -fr /usr/src/shadow-4.0.3
cd /usr/src
bzcat /mnt/data/new-lfs/src/shadow-4.0.3.tar.bz2 | tar xv
cd shadow-4.0.3

./configure --target=i586 \
--disable-nls --prefix=/mnt/lfs/usr \
make -e LDFLAGS=-all-static
make install

cd etc
cp -f limits login.access /mnt/lfs/etc
sed 's%/mnt/lfs/var/spool/mail%/mnt/lfs/var/mail%' login.defs.linux > /mnt/lfs/etc/login.defs
cd /mnt/lfs/usr/sbin
ln -sf vipw vigr
cd /mnt/lfs/usr/lib
ln -s ../../lib/


So I tried changing root passwd

bash-2.05a# passwd root
passwd: Cannot determine your user name.

bash-2.05a# /usr/bin/login
Unable to determine your tty name.

Can't figure it out are there more files need than the passwd and group files,
Does passwd and sulogin dependant onother programs (dependencies). I thought sulogin would
check passwd and group then login. Seems like its a bit more complicated. Both programs are static ie
ldd passwd
not a dynamic executable
must be a dependency problem or some config file I'm not aware of.
If so what are the minimum config files needed to log on root?

Thanks in advance
