That's 455MB of silently downloaded data, by default. Upon doing a yum<br>
upgrade, but rejecting the actual upgrade:<br>
<br>
[root@localhost cache]# du -sh *<br>
94M dnf<br>
446M PackageKit<br>
137M yum<br><br></blockquote><div>There is some problems in your numbes, not everything in cache is downloaded. In the dnf case only a repomd.xml (one for each repo, <5K) is download every time metadata cache is expired, and only changed metadata will be downloaded (repodata/*.xml.gz), the Fedora repo dont change, so it is only downloaded once, Updates is composed once every day, so it will only be downloaded one a day.</div><div>Rest of the content of cache/dnf is generated from the unpacked metadata, so the size of the directory don't tell any thing about how much metadata is downloaded and how often.</div><div><br></div><div>Tim</div><div><br></div></div>
