The cache will contain those files the installer got for you when you
selected and installed software, plus anything else you obtained after
the first reboot. For the sake of example let us suppose you installed
the mate desktop and the standard utilities.

The cache will not contain files from the base system, but that doesn't
matter because they are in the installer image, as is GRUB. The standard
system utilities are also in the image; no bandwidth penalty there.

I've not completely thought this through but you definitely would not
want to use the select and install software option, apart from leaving
standard utiliites ticked. You also would not want a network mirror but,
unless you are going to use sneakernet, you will want networking in
order to be able to connect to your primary machine.

After rebooting, create $HOME/debian and copy all the debs in the cache
on the primary machine to it. I think dpkg-scanpackages (in the dpkg-dev
package) might also have to be run. Your sources.list will have the
single line "deb file......" ; see the sources.list manual for details.
After that it's the usual apt-get update etc, etc.
