Here it is:

************************************************************************
1 - Using a temporary /var/cache/apt/archives
---------------------------------------------
You can use a temporary cache directory from another filesystem ( USB storage
device, temporary hard disk, filesystem already in use, ...)

*****************
Note : do not use a NFS mount as the network connection could be interrupted
       during the upgrade
*****************

For example, if you have a usb drive mounted on /media/usbkey:
- remove the packages that have been previously downloaded for installation:
   #  apt-get clean
- copy the directory /var/cache/apt/archives to the usb drive:
   #  cp -ax /var/cache/apt/archives /media/usbkey/
- mount the temporary cache directory on the current one:
   #  mount --bind /media/usbkey/archives /var/cache/apt/archives
- after the upgrade, restore the original /var/cache/apt/archives directory:
   #  umount /media/usbkey/archives
- remove the remaining /media/usbkey/archives.

You can create the temporary cache directory on whatever filesystem that is
mounted on your system.
