                     16:        configuration file updates and changes, and can fix most of
                     17:        the problems identified.
                     18:        This should make it much easier to upgrade a system's
                     19:        configuration from earlier systems (as far back as NetBSD 1.5).

                     32:        if you restart your machine from remote.  Note that sshd.conf needs
