Much, thanks.
But I still have a question about the hd-media sd-card images -- aren't
they only useful in concert with something which adds the .iso etc to
the image too? And therefore aren't they more usefully built along with
that iso? Otherwise how do you know how big to make the partition to
contain the iso at d-i build time given the varied sizes of .iso and
sd-card you can buy?
I think I'm probably just being dense here...
Ian.
