This is _NOT_ an up2date tree for installing CentOS. It is a snapshot of the trees that have been removed from the main CentOS servers as the numbered updates are released. This is provided for reference and to provide access to older released products, and we do not put security updates into the trees on this server. Please see this link for CentOS release information: http://lists.centos.org/pipermail/centos/2005-June/007570.html Unless you have a reason to use old and outdated software, you should instead be using http://mirror.centos.org/ or a mirror from http://www.centos.org/mirrors.
