Is this what i'm looking for?

$ ls /lib/x86_64-linux-gnu/security/

install : build/ly
        install -d /etc/ly
        install -D build/ly -t /usr/bin
        install -D ly.service -t /usr/lib/systemd/system
        ln -sf /lib/x86_64-linux-gnu/security/pam_loginuid.so /usr/lib/pam_loginuid.so

        rm -rf build/ly
