@Daniel,

Note that if you don't call fsync(), and you hence you don't check the error returns from fsync(), your application won't be notified about any possible I/O errors. So that means if the new file doesn't get written out due to media errors, the rename may also end up wiping out the existing file. This can be an issue with some remote file systems, like AFS, where you'll miss quota errors unless you fsync() and check the error returns on both fsync() and close(). But hey, if you don't care about that, feel free to write your applications any way you want.
