They are still built from the upstream sources, but might not map# to an exact upstream distro release.## These packages are made available soon after they are built, for people willing# to test their environments, provide feedback on content for the next release, and# for people looking for early-access to next release content.## The CR repo is shipped in a disabled state by default; its important that users# understand the implications of turning this on.## NOTE: We do not use a mirrorlist for the CR repos, to ensure content is available# to everyone as soon as possible, and not need to wait for the external# mirror network to seed first. However, many local mirrors will carry CR repos# and if desired you can use one of these local mirrors by editing the baseurl# line in the repo config below.#[cr]name=CentOS-$releasever - crbaseurl=http://mirror.centos.org/$contentdir/$releasever/cr/$basearch/os/gpgcheck=1enabled=0gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-centosofficial# CentOS-Debug.repo## The mirror system uses the connecting IP address of the client and the# update status of each mirror to pick mirrors that are updated to and# geographically close to the client.
