Indeed, ia32-apt-get assumes the default paths are in use. I never
heart of anyone changing them for the system wide config. I will have
to add code to support that.

Meanwhile is there any reason why you didn't use bind mounts?
  mount --bind /myaptetc_amd64/cache /var/cache/apt
  mount --bind /myaptetc_amd64/lists /var/lib/apt/lists
  ...

I will use apt-config to parse the systems apt.conf and extract the
relevant paths from that instead of the hardcoded paths in use now.
