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-go
frankly 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 nosense
if 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
*I* know how to disable them (or at least, I hope so! Maybe there
is/will be a foo package who decides to download its own copy too!), but
that's not the point of my post. What I expect is either: 1. disable all
kinds of potentially demanding internet access by default and let people
enable if they like; or 2. add an option to anaconda, or a post
installation option, so that the user can decide if he wants automatic
metadata/package updates for *Fedora* (not a specific DE/application) or
not. And the options should be applied to the whole distribution
consistently, even if you use multiple DEs.
(And hey, you might find 'yum clean expire-cache' a better alternative
for the 'rm -rf' command you use!)
[harry@srv-rhsoft:~]$ rpm -qa | grep -i packagekit

<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>
That would be great! ;) I think even 1 month of such experience should
be more than enough!
