OpenSSH uses a link to take a backup while replacing the known_hosts file: (1) link known_hosts to known_hosts.old (2) move new file to known_hosts (overwriting the link there) Since links are not allowed we replace link with rename: (1) rename known_hosts to known_hosts.old (2) move new file to known_hosts This means that there is a window between (1) and (2) where the known_hosts file is not available, but that is a really short window and is hopefully acceptable here. Fixes #2909.
