-cnid_dbd is now part of a new CNID framework whereby various CNID
-backends (including the ones present so far) can be selected for afpd
-as a runtime option for a given volume. The default is to compile
-support for all these backends, so normally there is no need to
-specify other options to configure. The only exception is
-transactional support, which is enabled as the default. If you want to
-turn it off use --with-cnid-dbd-txn=no.

-In order to turn on cnid_dbd backend support for a given volume, set
-the option -cnidscheme:dbd in your AppleVolumes.default file or
-equivalent. The default for this parameter is -cnidscheme:cdb.
