I need to do some testing with 5.3 as its suggested that 5.4 has "some bugs in the toolchain and libc". That being the case, I can install with a url and repo line pointing to a mirror with 5.3 still but how does one properly make sure during subsequent uses of yum it doesn't attempt to use 5.4 rpms? Is it simple enough to just manually set '$releasever' to 5.3 in the repo file or do I need to do anything else? What actually happens to the 5.3 repo so that `yum update` actually switches repo's when one is available? Thanks! jlc

But you won't get *any* security or other updates that way.> What actually happens to the 5.3 repo so that `yum update` actually > switches repo's when one is available?$releasever is "5" and centos/5/ is a link to centos/5.4/ on the mirrors.

How it was explained to me was that 5.4 is just a tag of a particular date of the 5.x tree, as was 5.3 and 5.2. In other words, there are no packages specific to 5.4, just a continuous set of updates to the 5.x tree. At some point you'll get a new package -- I believe from the centos-release package -- that bumps up the releasever string. At work we're using RedHat with Satellite and manage the updates with specific clone channels from the RHEL5 tree. That is, when updates get published we manually add them to our custom channels in preparation for deployment. On the CentOS side I've been experimenting with the Spacewalk project and it appears to allow us to do the same thing. Setup takes an hour or so for the initial configuration then another couple hours to get all the package information and binaries prepared.
