I think that would be the most reasonable approach.

dd(1) on ubuntu for example has these conv values:

       fdatasync
              physically write output file data before finishing

       fsync  likewise, but also write metadata

that, as far as I can tell, provide the same functionality as
dsync/sync flags.
