You mean F7 started to ship deltarpms? I didn't mean the tools
becoming available, but some big repo going through the maturing
phase. :=)

OK. I still don't know the mechanics behind it, but it surely needs at
least two rpms of the same package to create diffs (BTW does it
create N*(N-1)/2 deltas if there are N old packages around?). The
problem is that ATrpms' update scripts create the new repo in a
speparate stage w/o looking at the old one and then swap it in
place. Anyway, we'll see.
