Hi, Some time ago I wrote a little script elaguer.sh ("élaguer" means "to prune") which simply removes all packages that are *not* part of a minimal installation. First I created a list of packages that make up a minimal CentOS installation. On a fresh install, I would do something like this: # rpm -qa --queryformat '%{NAME}\n' | sort > minimal.txt Here's the resulting list of packages. I added a comment on top: https://github.com/kikinovak/centos-7-server-lan/blob/master/config/pkglists/minimal.txt And here's the script to prune the installation, e. g. remove everything that's not on the list. https://github.com/kikinovak/centos-7-server-lan/blob/master/elaguer.sh 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. One curious detail: it seems like it tries now to remove 'yum' and 'systemd', so 'yum' exits with an error. But it didn't do that before, so my guess is either 'yum' behaves differently now, or package dependencies are calculated differently. Anyway, I'm a bit clueless here. Any suggestions?
