31 .Nd system bootstrap configuration information
35 contains descriptive information on bootstrapping the system. Through
36 it you can specify the kernel to be booted, parameters to be passed to
37 it, and additional modules to be loaded; and generally set all variables
43 must contain the following two lines for
45 to be automatically processed:
47 .Dl include /boot/loader.4th
52 exists at installworld time, one with the above lines will be installed.
56 format was defined explicitly to resemble
60 some settings are treated in a special fashion. Also, the
61 behavior of some settings is defined by the setting's suffix;
62 the prefix identifies which module the setting controls.
64 The general parsing rules are:
67 Spaces and empty lines are ignored.
69 A # sign will mark the remainder of the line as a comment.
71 Only one setting can be present on each line.
74 All settings have the following format:
78 Unless it belongs to one of the classes of settings that receive special
79 treatment, a setting will set the value of a
81 environment variable. The settings that receive special
82 treatment are listed below. Settings beginning with
84 below define the modules to be loaded and
85 may have any prefix; the prefix identifies a module.
86 All such settings sharing a common
87 prefix refer to the same module.
90 Immediately executes a
92 command. This type of setting cannot be processed by programs other
95 so its use should be avoided. Multiple instances of it will be processed
97 .It Ar loader_conf_files
98 Defines additional configuration files to be processed right after the
101 Name of the kernel to be loaded. If no kernel name is set, no additional
102 modules will be loaded.
103 .It Ar kernel_options
104 Flags to be passed to the kernel.
106 Provides a password to be required by check-password before execution is
108 .It Ar verbose_loading
111 module names will be displayed as they are loaded.
115 that module will be loaded. If no name is defined (see below), the
116 module's name is taken to be the same as the prefix.
118 Defines the name of the module.
120 Defines the module's type. If none is given, it defaults to a kld module.
122 Flags and parameters to be passed to the module.
124 Commands to be executed before the module is loaded. Use of this setting
127 Commands to be executed after the module is loaded. Use of this setting
130 Commands to be executed if the loading of a module fails. Except for the
133 which aborts the bootstrap process, use of this setting should be avoided.
138 default settings can be ignored. The few of them which are important
140 .Bl -tag -width bootfile -offset indent
145 a bitmap will be loaded to be displayed on screen while booting.
147 .Pq Dq /boot/splash.bmp
148 Name of the bitmap to be loaded. Any valid bitmap path can be used.
151 .It Va loader_conf_files
152 .Pq Do /boot/loader.conf /boot/loader.conf.local Dc
153 .It Va splash_bmp_load
157 will load the splash screen module, making it possible to display a bmp image
158 on the screen while booting.
159 .It Va splash_pcx_load
163 will load the splash screen module, making it possible to display a pcx image
164 on the screen while booting.
165 .It Va userconfig_script_load
169 will load the userconfig data.
174 the vesa module will be loaded, enabling bitmaps above VGA resolution to
