As an outstanding part mentioned in #10737, we could just make the cluster config file and ACL file saving done with a more safe and atomic pattern (write to temp file, fsync, rename, fsync dir). The cluster config file uses an in-place overwrite and truncation (which was also used by the main config file before #7824). The ACL file is using the temp file and rename approach, but was missing an fsync. Co-authored-by:
