On ubuntu urbackup server use init.d instead of systemd

Urbackup deb provided on ppa for Ubuntu use init.d instead of systemd, why ?
Is it possible to setup a systemd script and disable init.d script ?

Additionnally, sometimes urbackup server crash for some reasons, using systemd it could be simple to auto-restart it using Restart=on-failure

Answer to myself
I removed /etc/init.d/urbackupsrv file and create /etc/systemd/system/urbackup-server.service
