nohup in shellcommands: cfengine waits indefinitely

[greg]

Hello there,

I have a startup script that I'd like to run whith shellcommands. This script 
uses nohup to run the
binary file:

#!/bin/shell
[...]
su - ${user} -c "nohup /opt/foo/bin/bar &"
exit 0
 
In my cfagent.cfg file:

shellcommands:

"/my/init/script start"


The problem is: when I run cfagent, it "waits" for /opt/foo/bin/bar. I have to 
stop /opt/foo/bin/bar
to make cfagent end properly. Otherwise, I have to Ctrl-c it.
I already tried "background=true", "useshell=false", the result is the same.
When I try "timeout=X", cfagent ends properly, but /opt/foo/bin/bar doesn't run.

I don't understand what's wrong with my script, or my conf ? Thanks a lot for 
your help !

        greg
