executing custom bash script

[venne]

Hi

I'm tring to execute a bash script, which should gives a dialog box, and 
make querries to a openldap server.

I've placed it into

$NFSROOT/myclass/10-postinst.sh

fai saw it, and tries to execute. but that seems freeze the system, and 
nothing appears anywhere.

some good ideas?

I'd like to execute the script at the beging of FAI process.(to make 
choice about PKI, IP and user's informations) is it possible?

regards.
