If I understand Jerónimo Leal correctly, he has a laboratory
containing a number of machines that cannot themselves
use the network installer (for whatever reason); he therefore
wishes to download the minimum necessary for an offline install,
which he will perform using a USB stick. As he was having
considerable difficulty recursively fetching a necessary and
sufficient fileset, I suggested that he might like to try
using on-the-fly zipping, which hypothesis I then tested.
The results were very impressive : 30 minutes download for
a full TLnet/2008 recurse (including ZIP time), a net
saving in bandwidth (small but real), and a total installation
time of 1H30, which is better than I have achieved using
any other methodology.
