Why was the update to 4.4 automatic? Having a lot of new features automatically installed it not why we run an "enterprise" OS. I would like to be able to plan and test that kind of events. A better way of handling it would be what I am used with from another "enterprise" distro: Already yum looks for the release in the "Version:" header of the package specified in yum.conf:distroverpkg (centos-release in our case). However the version is 4 and not 4.4 as one would expect (and 4 in the 4.3 version as well). # rpm -qp --queryformat="%{version}\n" centos-release-4-3.2.src.rpm 4 # rpm -qp --queryformat="%{version}\n" centos-release-4-4.2.i386.rpm 4 This means that $releasever in our CentOS-Base.repo will be 4 and not 4.4 as we would like. If the the "Version:" of the centos-release rpm is in sync with the CentOS release version all you have to do to switch is: rpm -U "new centos-release rpm" yum update yum yum update Simple and predictable. /// joakim
