I noticed that F21 can potentially download repository metadata 3 times: 1. Yum cache 2. DNF cache 3. PackageKit cache! It really hurts to see how Fedora ignorance towards different kind of users is being increased as time passes. If Fedora is an international distro, it should try to consider condition of different users, not just a portion of them. Fedora repository metadata format was already hostile, it wastes bandwidth considerably downloading mostly useless data repeatedly. Things got worse for DNF as it decides to also always download filelists. Now, Fedora 21 contains yum, dnf and PackageKit (software center) with new backend. Surprisingly, PackageKit uses its own separate cache. DNF refreshes its cache automatically (without user's consent) every 3 hours by default (according to 'man dnf.conf'). PackageKit also does the same, but I don't know when it does (also without user's consent).
the automatic metadata refresh is a no-gofrankly in the meantime only the metadata are half as large as some of my server setups at all (our asterisk PBX needs 850 MB with F20)
Now, if you are exclusively a 'yum' user, you'll end up with 3 repository metadata downloads
"systemctl mask dnf-makecache.timer" stops the new nosenseif you are not using GNOME and YUM from CLI you can remove package kit at all and frankly my typical command is "rm -rf /var/cache/yum*; yum upgrade" because when i look for updates i want the *now* recent metadata and don't need them refreshed one hour ago
[harry@srv-rhsoft:~]$ rpm -qa | grep -i packagekit [harry@srv-rhsoft:~]$<sarcasm>maybe someone should place a bandwidh-limiting of 0.5 Mbit and a onhtly limit of 1 GB per month in front of developers to wake them up</sarcasm>
