 If you use `rpmconf` to upgrade the system configuration files supplied with the upgraded packages then some configuration files may change. After the upgrade you should verify `/etc/ssh/sshd_config`, `/etc/nsswitch.conf`, `/etc/ntp.conf` and others are expected. For example, if OpenSSH is upgraded then `sshd_config` reverts to the default package configuration. The default package configuration *does not* enable public key authentication, and allows password authentication.

+If you upgrade across two releases (e.g. Fedora 35 to 37), you must supply the old release version to `remove-retired-packages`:
