Proper way to sync an SD card prior to reboot

[Jim Panetta]

To prevent any data loss due to non-flushed buffers at a commanded reboot, we 
would like to sync a multi-partition SD card during our reboot procedure.

Is it enough to issue rtems_disk_fd_sync(fd) for each mounted partition?

Or should we be using unlink(path) as Sebastion Huber mentioned in his 
correspondence with Ali Nasir this April?
