Gdm and Gnome-games errors only when installed from scratch

[Arco van Geest]

/DEPOT/catalog/Gdm/GDM-RUN/postinstall fails on the useradd command (passwd busy).

#!/sbin/sh

PATH=${SWPATH}:/sbin:/usr/bin
export PATH
#add Changes for pwd.lock
touch /etc/.pwd.lock > /dev/null 2>&1 || /bin/true
chmod 400 /etc/.pwd.lock > /dev/null 2>&1 || /bin/true
chown root:sys /etc/.pwd.lock > /dev/null 2>&1 || /bin/true
#/add

/usr/sbin/groupadd gdm > /dev/null 2>&1 || /bin/true
/usr/sbin/useradd -g gdm gdm > /dev/null 2>&1 || /bin/true

The same addition could be needed in Gnome games
