The GPG-keys are different.
The lists are not different as a sort and diff would show you
Generally:
- ignore all gpg-pubkey RPMs
- don't worry if the backup server installation (SME distro RPMs) is newer. A --rise will work
- worry about contribs RPMs not installed or of different version on the backup server.
- don't let Affa generate the Affa RPM comparison list if you don't plan a --rise (set RPMCheck='no'), or just ignore the list.
