debugging extras packages is basically impossible right now, as we don't include a repo file pointing at the debuginfo's in /etc/yum.repos.d/ (Even if its disabled by default, we should make this as easy as possible for end users to report useful bugs).
I'm working on rearranging how our bits land on public servers, as well as changing some of the repo stuff. Most likely debug and srpms will be outside the os dir and each require their own repo file, or maybe both in the same repo file for debugging. I hope to have this resolved by Test3.
There is a debug directory with repodata under all of the extras trees. I use a repository definition like this (in fedora-extras-devel.repo) to access them. [extras-devel-debug] name=Fedora Extras $releasever - Development Tree - Debug baseurl=http://download.fedora.redhat.com/pub/fedora/linux/extras/development/$basearch/debug/ enabled=0 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-extras gpgcheck=1
I'm aware of that, but this should be shipped as part of fedora-release.
fedora-release now includes extras-debuginfo repo. (as well as debuginfo repos for the rest of the repos)
