thanks for your work.
As far as I understand your script, you remove our internet repo from the sources.list, and add a key to the local deb.
This will indeed make sure, that no package will be taken from our repo. Unfortunatly, we will still need the internet, for things like sqlCVS update, and the installation of files like the Microsoft truetype fonts.
I will modify the install and do a snapshot probably today, to not include the internet repo.
From what I can make out from the script, it only moves the order of the sources.list. So it look local first before going to the internet.
what we could to is just add a script at the end of the installation to move it back in the order it is now if you are worried that update will not take place.
So it will look locally and install the .deb from local disk then after install it change the source.list back to what it is now and all it good.
I am with Phenigma on this one. Here in NZ we still have to deal with caps from our ISP. So don't want to download a 4 GB iso and then install where the install download it all again just because it does not look locally first for the install files..
