I added the following into /etc/yum.conf ( from http://wiki.garylaw.net/doku.php?id=...unix:linux:yum
) but it does not seem to work. Do I have to modify anything else?
name=CentOS-$releasever - Base
name=CentOS-$releasever - Updates
#packages used/produced in the build but not released
name=CentOS-$releasever - Addons
#additional packages that may be useful
name=CentOS-$releasever - Extras
