OK, this isn't a direct DNF/YUM item, but still...
I have several workstations/laptops with the same Fedora version (currently 20):
* Downloading the same RPM's/DRPM's for each of these hosts is a huge waste.
* OTOH, I haven't found a no-brainer yum-proxy (a-la Debian's apt-proxy
* I update them daily. I do this manually to have a quick look at what changes.
* Sometimes I update via KDE apper (which use PackageKit, which calls
* But most of the time I do this over ssh, using DNF (it's faster...)
So my workaround is:
* I have a script: "yumcache_to <hostname>"
* This copies (via rsync) all RPM's/DRPM's under /var/cache/yum.
Last year I also added /var/cache/dnf.
* It doesn't copy the meta-data files (for safety -- maybe they are in
the middle of update via PackageKit or some cron-job).
* When I started using DNF, I modified my script to also cross-hard-link
all packages between yum and dnf caches before the rsync.
* This effectively make them behave as a unified cache. Since some of
my updates are via yum (e.g: via PackageKit) and some via dnf -- this
cross-hard-linking also save extra downloads.
For this to be effective:
* I have a keepcache=1 in /etc/yum.conf and keepcache=true in /etc/dnf/dnf.conf
* I have another "yumcache_dillute" script that remove old RPM's from caches
As said, this isn't directly yum/dnf issue, but your are the people that can
think of the missing pieces (some yum/dnf proxy -- that maps url's
across mirrorlist -- so the same RPM's is a proxy hit, regardless of
which exact mirror it was pulled off)
Thank you all,
