I was hoping ot a more dynamic approach though since the number of affected machines is in excess of 150. For example simply changing the $releasever to 6.3 and then to 6.4 and then to 6.5 every time a new version come along is not practical. Looking into the 'man yum.conf' I find that $releasever This will be replaced with the value of the version of the package listed in distroverpkg. This defaults to the version of ‘redhat-release’ package. distroverpkg The package used by yum to determine the "version" of the distribution. This can be any installed package. Default is ‘redhat-release’. You can see what provides this manually by using: "yum whatprovides redhat-release". Doing [root at cs6979 yum.repos.d]# yum whatprovides redhat-release ................. centos-release-6-4.el6.centos.10.x86_64 : CentOS release file Repo : CS-base Matched from: Other : redhat-release centos-release-6-3.el6.centos.9.x86_64 : CentOS release file Repo : installed Matched from: Other : Provides-match: redhat-release So the installed package is version 6.3. Am I overlooking/misinterpreting something? Andreas
