[PD] autoboot in Linux

[Sukandar Kartadinata]

Hi,
I'm trying to make a Linux system autoboot a pd patch. Being still 
relatively new to Linux I can't quite figure out what I'm doing wrong. 
Maybe you can help. Here's what I do:

my pd startup script looks like this:
#! /bin/sh
# chkconfig 2345 98 98
# description: starts pd
echo -n "starting pd..."
/usr/bin/pd -nogui -nomidi \
-lib /usr/lib/pd/extra/OSC \
-lib /usr/lib/pd/extra/zexy \
/home/glui/proj/pd/GPlayerStereo.pd &

I save this as pd_start in /etc/init.d/

then: chkconfig --add pd_start
checking with chkconfig --list shows that it's enabled at run level 3

after reboot no sound nor an an entry in the process list
however /var/etc/messages shows:
Oct 13 22:05:59 digimatrix pd_start: starting pd...
Oct 13 22:05:59 digimatrix pd_start: OSCroute object version 1.05 by 
Matt Wright
. pd: jdl Win32 raf.
Oct 13 22:05:59 digimatrix rc: Starting pd_start: succeeded

no mention of zexy being loaded though




thanks,
Sukandar
