Bug#1039225: icecast2: proposed systemd unit

[Kevin Otte <nivex@nivex.net>]

I've read the upstream bug report, and I understand their reluctance to 
package a systemd unit. I have prepared one based on the linked Fedora 
unit file, and I did have to make some modifications for Debian 
packaging (change executable and config file path, add user and group IDs).

I have tested this unit file to ensure it provides the same 
functionality as the init script.
