SUSE 10 startup script

Hi,

Here is a startup script for SUSE 10 which works nicely for me. The script tests for the existence of the config file and binary. Debug level and music root are specified as vars in the script. since I have my music on a slow-ish firewire drive, sometimes it’s not visible when the machine boots; this script waits for the specified music directory to appear before running mt-daapd.

The script behaves nicely with respect to stop / start commands and return values.
