I've been designing the infrastructure for a new team using CentOS 6 and Puppet. I'm still learning Puppet, but thought I had things pretty well under control. After this week, I'm beginning to wonder… :-) In the last week I've had versions of three packages disappear from the yum repositories I'm using, both EPEL and the standard ones from a base CentOS 6.3 install. Since I'm trying to install specific versions of packages with Puppet, this is a problem. The most recent one that just turned up this morning is kernel-devel. I have the following resource defined in one of my Puppet manifests: package {"kernel-devel-${::kernelrelease}": alias => 'kernel-devel', } I'm trying to ensure that I've got the kernel-devel package installed that matches the kernel I'm currently using. I naively assumed that once a package was made available via the official CentOS mirrors that it would never disappear. That doesn't appear to be the case. I have kernel-2.6.32-279.19.1.el6.x86_64 installed. kernel-devel-2.6.32-279.19.1.el6.x86_64 is gone, apparently replaced with kernel-devel-2.6.32-358.0.1.el6.x86_64. I have a couple of other packages that have given me problems, too, namely ngircd which was upgraded from 18 to 20.1. How do I manage this problem? Do I need to maintain my own mirrors? That seems like a horrible solution. Is there another CentOS repository I should be using? Am I just going about this all wrong? Thanks, Brian -- Brian Lalor blalor at bravo5.org
