[Icecast] multiple icecast server instances on debian system

[tzara]

 hello,

 i am trying to have multiple server instances on different ports on the 
 same debian server.
 i thought if i had (along side the standard server files):

 /etc/icecast2/icecast+.xml config file (with changed port number)
 /etc/default/icecast+ pointing to new config file
 new log files with 777 permissions (for the sake of testing)

 and an /etc/init.d/icecast2+ file to start it all up then it would all 
 work ok

 but no it doesnt work:
 so then i thought i maybe need new web and admin dirs in 
 /usr/share/icecast2.... then i would need new symlinks etc. - so its 
 starts to get messy... so before i start making this mess, i ask here... 
 am i going about this the wrong way?


 (/usr/share/icecast2) % sudo /etc/init.d/icecast2 start
 Starting icecast2: Starting icecast2
 Detaching from the console
 icecast2.

 (/usr/share/icecast2) % sudo /etc/init.d/icecast2+ start
 Starting icecast2+: zsh: exit 1     sudo /etc/init.d/icecast2+ start

 or:

 (/usr/share/icecast2) % /usr/bin/icecast2 -b -c 
 /etc/icecast2/icecast+.xml
 Starting icecast2
 Detaching from the console
 (/usr/share/icecast2) %

 but no second instance, could be some file permission or ownership 
 tweek i have missed or could be i am going about it all the wrong way

 are there some docs about this somewhere? i imagined it might be a 
 common thing that people might want to do...

 any ideas welcome!

 thanks
