You said you have to keep around the old rpms and you meant the repos have to keep around the old rpms? Does the user (me) have to store the old rpms on my hard drive to be combined with the delta rpms?<br><br>Thanks for all the info btw,

<br> the old rpms around for delta generation (they don't need to be in<br> the repo, though) and the mirrors have to fetch all the new<br> deltas.<br>- create only one delta between the last version and the new one.<br>
This creates a chain of deltas, so the mirrors only have to pick<br> up one delta. The disadvantage is that you have to use a special<br> server that combines the deltas on the fly or, if you don't want<br> that, clients that have an old version must fetch more than one
<br> delta and combine them.<br><br>In any case, keeping deltas against the last 10 versions roughly<br>doubles the repo size.<br><br>Cheers,<br> Michael.<br><br>--<br>Michael Schroeder
