fai-cd : Need to extract a tarball

[TOUZEAU DAVID]

Dear

I would like to fai extract a tarball in a particular folder.
After create the CD, fai encounter error

"localhost/install-20080505_105153/fai.log:ftar: No matching class found 
in /var/lib/fai/config/files//opt"

To explain, this is my procedure :

1) I have created a file
/srv/fai/config/files/opt/FAIBASE.tgz

2) modify the content of
srv/fai/config/hooks/instsoft.FAIBASE

#! /bin/bash

[ -s $target/etc/kernel-img.conf ] || fcopy -Bi /etc/kernel-img.conf
ftar /opt && echo "/opt"


3) Make cd
fai-cd -f -m /home/mirror /root/mysio.iso

What's wrong ?
What is the good procedure to ?

Best regards
