Why does SSHD not detach from host key?

Specifies a path to a certificate file to identify sshd during key exchange. The certificate file must match a host key file specified using the -h option or the HostKey configuration directive. When this option is specified, sshd will not detach and does not become a daemon. This allows easy monitoring of sshd.
