[yocto] install -m 0644 ${S}/lib/systemd/system/${PN}.service ${D}/${systemd_system_unitdir} failed to add service file to ${systemd_system_unitdir}

Hi,

I set up the configuration for service files at following:

SYSTEMD_SERVICE_${PN} = "${PN}.service bootstrap.service"

do_install() {
    ..............
    install -d ${D}/${systemd_system_unitdir}
    install -m 0644 ${S}/lib/systemd/system/*.service
${D}/${systemd_system_unitdir}
}

Despite both service files are in build directory, the final image
installation does not include those service files, appreciate anyone
help.

Thank you.

Kind regards,
