[yocto] Can't replace login.defs with shadow-sysroot bbappend

[Zhenhua Luo]

Hi Oliver, 

The following line in shadow-sysroot.bb disables the final binary packages generation. You can try to add bbappend for shadow to do the customization. 

# don't create any packages
# otherwise: dbus-dev depends on shadow-sysroot-dev which depends on shadow-sysroot
# and this has another copy of /etc/login.defs already provided by shadow
PACKAGES = ""


Best Regards,

Zhenhua
