Well, in that case you are distributing Knoppix. Other people then
redistribute it. For this, if you just make the source available from
the same place that the cdimage is available, then you're fine. It
sounds like you already have everything set up to burn source CD's.
Why don't you just put up an image of that? Then you wouldn't have to
bother with the 3-year warranty.

You can still keep the three-year offer as a courtesy. The problem is
that you have to have available, three years from _now_, whatever is
on your website _now_. That is a bit of a pain for you.
