>For durability fsync is sufficient if you do it on the file and the directory. To combine atomic and durable you can do the write, fsync, rename, fsync dir dance.
Right. This allows for the correct behaviour but I wouldn't conclude that POSIX is a transactional API. I would regard this as being able to build a transactional API on top of it; but not transactional in itself. I mean, if you had to do the same dance in SQL (insert to dummy pkey and then update the entry) you would rightly dismiss it.
