Hi,
yum-2.4 and required dependancies for CentOS-3 are now available for i386 and x86_64 in the centosplus repository.
The default version still is 2.0, nothing changes for those who don't want/need the new features (for example: fastestmirror, priorities and protectbase).
For those who don't want to update to yum-2.4 but still use the centosplus repository, add to your /etc/yum.conf the line: exclude= yum
The old metadata for yum-2.0 (yum-arch) and the new metadata for yum-2.4 (createrepo) are BOTH generated on all the CentOS-3 repositories on the centos.org mirrors.
Caveat: the 3rd parties repositories using only yum-2.0 metadata will NOT be compatible with the yum-2.4 until their respective maintainers also create the new metadata.
yum update procedure: 1) enable the centosplus repository in /etc/yum.conf #additional packages that extend functionality of existing packages [centosplus] name=CentOS-$releasever - Plus baseurl=http://mirror.centos.org/centos/$releasever/centosplus/$basearch/ gpgcheck=1
2) update # yum update
3) fix the yum.conf file: # mv /etc/yum.conf /etc/yum.conf-2.0.x # mv /etc/yum.conf.rpmnew /etc/yum.conf
4) optionally re-add the custom repositories to /etc/yum.repos.d
Cheers,
The CentOS team
