Creating a 100% offline FAI installer

Hi Thomas,

here is another question. I want to create a 100% offline installer  
via FAI. The resulting system, though, shall have all sources.list  
files setup correctly, so that packages will get updated via http  
locations. Furthermore, the to-be-installed system will have these APT  
conf variables set:

Acquire::http::Proxy "http://webcache:3128";
Acquire::ftp::Proxy "http://webcache:3128";

With fai-mirror, I have created a reprepro tree now containing (as it  
seems) all required packages.

With fai-cd, I created an ISO images, containing that mirror. During  
installation, the mirror gets also mounted into the /target chroot (to  

Also the sources.list file of the NFSROOT gets replaced by this:

deb [trusted=yes] files:/media/mirror cskoeln non-free main contrib

However, in the /target chroot, I only have the http package archives  
configured in /etc/apt/sources.list(.d)/*.list as found in my FAI  
config space. The configuration that states how the APT setup shall be  
after the installation has finished.

However, this APT sources configuration is also already used during  
the FAI installation. I was expecting that these settings get  
overriden by APT using file:/media/mirror instead.

So, what is the best approach to address this? Do I have to add a  
sources.list with file:/media/mirror manually to my FAI config space  
under files/, manually, (and disable all the others temporarily? Or am  
I missing some mechanism that on-the-fly adds file:/media/mirror as  
APT mirror inside the /target chroot?

Thanks for any feedback provided!
