When you use delta rpm's with presto or without even, do they rely on you having the original rpm on hand, or do they download both the original and the difference between the original and then construct it? (specifically with yum)Does presto or any other system need to be keeping a cache of all installed rpm's for delta rpms to work? Do delta rpms work without presto, or are the integrated?Thanks in advance :-)
