Question about Debian Installer and Simple-CDD

[Adam Saleh <adamthecamper@gmail.com>]

Hello,

I am using simple-cdd to make my custom debian install cd. 

Strictly speaking I am just trying to automate instalation of my debian-servers 

and creating my own instal cd looks like a good solution.

I have tested simple-cdd with custom preseed file (folowing the howto http://wiki.debian.org/Simple-CDD/Howto)

and it worked fine, but when I added post-inst script, it didn't do any changes.

In folder profiles/ I have files MINIMAL.preseed (containing functional preseed file) and MINIMAL.postinst.

File MINIMAL.postinst contains

#!/bin/sh

mkdir -p /target

touch /target/foofile

Then I executed "simple-cdd --profiles MINIMAL"

After automatic instalation, I checked / on my new system and I found neither foofile nor directory target.

(To explain the target thing, I remember, that debian installer installs everything to /target and this then becomes the root system,

and I wasn't sure whether postinst script operates on debian-installer root or installed system root)

This proved me, that I don't understand this and therefore I need to ask:

How does the postinst script work in debian-installer?

and

How can I check, whether simple-cdd included my postinst script indo my iso?

Thanks in advance for any helpful hints :)
