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

                     47:        if you restart your machine from remote.  Note that sshd.conf needs
                     48:        to be changed (due to the use of "/etc" inside).

                    116:        UPDATING for these systems, as tool updating is taken care of
