Wow, this seems like a fairly heated topic of discussion now. Whether or not you think a UT server should be started by init.d is up for debate, but I think have that type of script with flexibility and consistency it provides will be useful people, at the very least for those with Linux server administration backgrounds.
The ucc-bin file is a poorly implemented server, at least from a process interaction viewpoint. Just the fact that you launch it from its own directory is a major pain. I got around this with my script by writing a helper application that spawns a child process to run the server, and then it monitors for a TERM signal, and kills the child at the appropriate time. I had to do this to get the stop/restart functionality to work as desired.
Anyways, without further ado, I give you Unreal Tournament 2004 Server Daemon 0.1. It is released under the GPL, and you can download it from
