It isn't. And you can do it anyway: 1. open target, keep it open. 2. do the safe open+write dance on the temp target. 3. get metadata from target by fd 4. apply metadata to temp target by fd 5. atomic rename 6. close both fds 7. sync parent dir. -- "One disk to rule them all, One disk to find them.
