| * The rpm database format changes from Berkeley DB to SQLite, conversion is automatic after rpm package set update. Backup of the old database is saved as ''/var/lib/rpm.rpmbackup-VERSION-RELEASE'', using version and release of the package that is installed (not the old one). Ex. if the old package was rpm-5.4.15-58 and the new one is rpm-4.16.1.2-1, the backup of the database will be in ''/var/lib/rpm.rpmbackup-4.16.1.2-1''. | * The rpm database format changes from Berkeley DB to SQLite, conversion is automatic after rpm package set update.
