Hi, right now Copr is using stock mock, with its default configuration. Which means that Copr builders are downloading packages from Fedora mirrors. I find this sub-optimal, because: * sometimes is mirror little bit off-sync and occasionally this result in failed builds. * while mirrors are generally good thing, primary Fedora servers are AFAIK just few racks away from Copr. In term of measurable data it is 100 ms of ping vs. 4 ms of ping.
Therefore I plan to replace: metalink=https://mirrors.fedoraproject.org/metalink?repo=fedora-$releasever&arch=... in mock config with: baseurl=http://dl.fedoraproject.org/pub/fedora/linux/releases/$releasever/Everything...
and similary for epel, rawhide and F21. But before I proceed, would like to ask if this is ok? Or should I rather not use dl.f.o for some reason?
