I don't think this is appropriate to fix in ltsp-client-builder, as it
won't work when running outside of debian-installer.

I'd suggest fixing the above 000-arch-detection script to set the proxy
in the same way the http-proxy plugin is doing:

        if [ -z "$http_proxy" ]; then
                eval $(apt-config shell http_proxy acquire::http::proxy)
                [ "$http_proxy" = "false" ] && http_proxy=""
                export http_proxy
        fi

The 000-arch-detection script you've referenced also abuses the
commandline processing internals ($option_*_value) which means you're
overriding the commandline options specified by the user, for what it's
worth.

live well,
