My Icecast/Icecast-KH init.d script for Debian. Written as simple as possible using only standard commands for better cross-platforming.
Put script into /etc/init.d dir, then:
sudo chmod 755 /etc/init.d/icecast-kh
sudo chown root:root /etc/init.d/icecast-kh
systemctl enable icecast-kh.service
service icecast-kh {start|stop|status|reload}
Add restart section.
