func AtomicWriteFile

func AtomicWriteFile(path string, data []byte, mode os.FileMode) error

AtomicWriteFile writes data out. It writes to a temp file first, fsyncs that file, then swaps the file in. os.Rename is an atomic operation, so this sequence avoids having a partially written file at the final location. Finally, fsync is called on the directory to ensure the rename is persisted.
