Problem with startscript in boot mode

Hello.
I have following problem with starting binary program during boot proces.
Sorry that I can not send detailed information of biary but I will try to describe generally the issue in example:
Prerequisites:
Manually binary should be fired from command line by common user - lets call him user.
So I need to login as root and do:
su - user
nohup /whole/path/to/bin/binary_program &
exit
It works fine. I can logout and binary is run anyway.

I have tried with different configurations and finally I tested manually following setting that works when fired from command line.
So I did:
1. In /sbin/rc4.d/ I created S888binary_program symlink to
/sbin/init.d/binary_program
2.Inside /sbin/init.d/binary_program
I put following two lines:
/usr/bin/su - user -c "/home/user/binary_program.sh " >> /dev/null
exit 0
3.File /home/user/binary_program.sh contains:
nohup /whole/path/to/bin/binary_program &
exit 0

When go to /sbin/rc4.d/ and I run
./S888binary_program
I starts the program as expected.
But after reboot process I can not see it as started.

How I can debug this problem?
Maybe it is related to binary itself?
I will try to examine this with more simple program yet but maybe someone would have an idea what can be wrong.

Well, did you demonize it?
Can you print the PID when you do nohup? Is there a nohup.out file?
It would help if you didn't send the su - user output to /dev/null.

You may have to use tusc:
nohup tusc -fp -o tusc.out /whole/path/to/bin/binary_program &

I think the problem was in /etc/inittab
default initdefault was 3 instead of 4.
I will test it now
