51 internal actions according to the settings found there.
55 file is included from the file
56 .Pa /etc/defaults/rc.conf ,
57 which specifies the default settings for all the available options.
58 Options need only be specified in
60 when the system administrator wishes to override these defaults.
62 .Pa /etc/rc.conf.local

89 Informational messages are displayed when
90 a condition that is not serious enough to warrant a warning or
