-Before installing an upgraded version of Netatalk that is linked against a newer BerkeleyDB lib, run `dbd \-u \&.\&.\&.` from the OLD Netatalk pior to upgrading on all volumes\&. This removes the BerkleyDB environment\&. On exit cnid_dbd does this automatically, so normally calling dbd \-u should not be necessary !
