well that certainly makes sense. the differences between r0 - r4
should be pretty minimal. jigdo operates on a diff scheme, I take it?

well, here i think it falls apart since you're essentially going to be
downloading every package to go from sarge to etch, aren't you?
certainly, though, following sub-releases as above makes sense.

your desire to limit server load is commendable. I suspect though,
that the work involved may not be worth it. As I said before, you're
looking at using only a percentage of the total system anyway. By far,
(and this comes with nothing to back it up, just gut instinct) the
least bandwidth intensive way to install is use a net-install image
and then download only those packages you need for your system and
nothing more.
