Hi,

ln -s busybox addgroup
ln -s busybox adduser
touch group gshadow passwd shadow
./addgroup -g 0 root
cat group gshadow
root:x:0:
root:!::
./adduser -h /root -s /bin/bash -D -G root -u 0 root
cat group gshadow passwd gshadow
root:x:0:root
root:!::root
root:x:0:0:Linux User,,,:/root:/bin/bash
root:!::root
 ./addgroup users
cat group gshadow
root:x:0:root
users:x:1000:
root:!::root
users:!::
./adduser -h /home/dave -s /bin/bash -G users -D  dave
cat group gshadow passwd gshadow
root:x:0:root
users:x:1000:dave
root:!::root
users:!::dave
root:x:0:0:Linux User,,,:/root:/bin/bash
dave:x:1000:1000:Linux User,,,:/home/dave:/bin/bash
root:!::root
users:!::dave

This seems to work locally for me. You could also try:

echo "root:x:0:0:root:/root:/bin/bash" > /etc/passwd
echo "root::14389:0:99999:7:::" > /etc/shadow
echo "root:x:0:" > /etc/group
echo "root:!::" > /etc/gshadow
chmod 644 /etc/passwd
chmod 644 /etc/group
chmod 600 /etc/shadow
chmod 600 /etc/gshadow
passwd root
addgroup users
adduser  -h /home/dave -s /bin/bash dave
addgroup dave users



Ciao,
