What's the point of having a function that returns a boolean if it
just returns true all the time? Wouldn't it be better to have a set
of semantics closer to the unlink() part, where the call of stat()
fails with an ERROR for (errno != ENOENT) and the fsync call returns
false with a WARNING?

installcheck deployments may not like that.
