This script worked perfectly for some time. But now it seems like something has changed somewhere under the hood. Because when I run it now, the script fails at the final package removal stage.
I would hazard to guess that the flaw is simply that from time to time, packages are added to the minimal install as a side effect of adding in new dependencies. If you had a minimal install and simply ran "yum update", you would periodically see yum report that it would install new packages for dependencies, in addition to the updates. As that is the case, you will need to update your minimal package list immediately before running the pruning script in order to avoid removal of core packages.
I wonder if it might work to use a yum transaction, in which you first remove everything (which avoids the need for the list entirely), then adds the minimal package set, and then commits the transaction...
