Bug#928931: The inability to use apt-setup/local0/repository makes it impossible to upgrade to Debian 10

[Magnus Määttä <magnus@novell.stoldgods.nu>]

Hi,

I'm also having this issue which is making it impossible to upgrade to 
Debian 10 from Debian 9.

I'm depending on the possibility to add a repo during PXE-boot. Using 
late-commands is not an option as there doesn't seem to be any
$selected_packages variable I can use to actually install the packages 
selected during installtion, while ignoring the fact that it's
going to try to install them without the repo available, making the 
installation fail anyway.

Someone gave the recommendation to use different preseed files, but that 
also is not an option as the boot menu would need to have
50-100 entries to accommodate for the most common options of package 
selections (which will make the size of the installation vary between
15GB and 80GB).

So for us, this is a real show stopper for using Debian 10 as it makes 
it impossible to install (manual installation is not an option)..
