What forward and backward compatibility guarantees are there?RPM will keep support for BDB for now. But to get rid of the dependency it will be dropped at some point in the future. So it will stay backward compatible. The file format is clearly not forward compatible (although you will be for now be able to still use the old format)
"clearly not forward compatible"?there needs to be a migration path to get a existing bdb rpmdb converted our you will blow with "will be dropped at some point in the future" a ton of users and admins to hell
we run 30 machines originally installed with Fedora 9 and updated until now to F23 which surived UsrMove, migration to grub2 including make space for grub2 on the bootdrive with parted and the switch to systemd without install them from scratch
so there is no justification to declare one need to install from scratch just because rpm which works for many years fine changes it's storage format
