Запустить ddclient как сервис в 16.04

На github wiki или sourceforge wiki нет описания того, как это сделать, просто как

Есть файл

/etc/default/ddclient

# Configuration for ddclient scripts
# generated from debconf on Thu Jul 27 17:32:33 ACST 2017
#
# /etc/default/ddclient

# Set to "true" if ddclient should be run every time DHCP client ('dhclient'
# from package isc-dhcp-client) updates the systems IP address.
run_dhclient="false"

# Set to "true" if ddclient should be run every time a new ppp connection is
# established. This might be useful, if you are using dial-on-demand.
run_ipup="false"

# Set to "true" if ddclient should run in daemon mode
# If this is changed to true, run_ipup and run_dhclient must be set to false.
run_daemon="true"

# Set the time interval between the updates of the dynamic DNS name in seconds.
# This option only takes effect if the ddclient runs in daemon mode.
daemon_interval="300"

Если я пойду к

sudo systemctl edit --full  ddclient.service

файл создается с этими параметрами

Это не работает при загрузке, хотя..? Я могу только запустить службу вручную с помощью sudo etc/init.d/ddclient start или же sudo systemctl start ddclient.service
