Exactly. To me a minimal install has just enough to run sshd, an
editor*, and yum. It’s not very useful, so then I add diagnostics,
logging and management software, and it is no longer minimal.
My typical approach is to run `package-cleanup --leaves --all` or `yum
leaves` (might need software not on CentOS 8) and justify everything
that is there. I have about 85 leaf packages on a CentOS 7 web
server, so a minimal package set should be smaller. Experiment with a
disposable VM so it is easy to recover from mistakes.
