We create our known_hosts by collecting all public host keys and adding
all hostnames and IP numbers but leaving the comment. Example:

derga,derga-p,10.9.20.5,192.168.14.11,derga-p.priv.lan,derga.cluster ssh-rsa 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 noe@derga
