This is a directory that contains ALL the old packages (including ones no longer in the repo). These will be used to create deltas from old versions to new versions. --max-delta-rpm-size - If you want to only process packages UNDER a certain size. Note that this refers to the input package (from what I understand). You'll find the deltas will usually be around 20% of the size of the full package (sometimes even less). -- Steven Haigh Email: [log in to unmask] Web: https://www.crc.id.au Phone: (03) 9001 6090 - 0412 935 897 Fax: (03) 8338 0299
