If you remove the point release numbers from your update paths you do
not need the old versions. If you really need the old updates use
http://vault.centos.org/
>From http://mirror.centos.org/centos-4/4.4/readme
------------------------------------------------------------------------
This directory (and version of CentOS) is depreciated. For normal
users,
you should use /4/ and not /4.4/ in your path. Please see this FAQ
concerning the CentOS release scheme:
http://www.centos.org/modules/smartfaq/faq.php?faqid=34
If you know what you are doing, and absolutely want to remain at the 4.4
level, go to http://vault.centos.org/ for packages.
------------------------------------------------------------------------
To simplfy our yum configuration I disable all the repo files in
/etc/yum.repos.d and call the yum configuration from a local web server
in yum.conf by using the include statement. One change on the web server
changes the yum configuration on all CentOS machines.
In the yum.conf I add
# Site yum files
include=http://ourserver.ourdomain.com/centos/yum/centos.repo
include=http://ourserver.ourdomain.com/centos/yum/centos-updates.repo
The centos.repo looks like this,
[base]
name=CentOS-$releasever - Base
baseurl=http://ourserver.ourdomain.com/centos/$releasever/os/$basearch/
enabled=1
gpgcheck=1
And the centos-updates.repo looks like this,
[updates-released]
name=CentOS-$releasever - Updates
baseurl=http://ourserver.ourdomain.com/centos/$releasever/updates/$basea
rch/
enabled=1
gpgcheck=1
[custom-repo]
name=CentOS-$releasever - Custom-rpms
baseurl=http://ourserver.ourdomain.com/centos/$releasever/customrepo/
enabled=1
gpgcheck=1
Hope this helps.
