32 .Nd system bootstrap configuration information
36 contains descriptive information on bootstrapping the system. Through
37 it you can specify the kernel to be booted, parameters to be passed to
38 it, and additional modules to be loaded; and generally set all variables

57 format was defined explicitly to resemble
61 some settings are treated in a special fashion. Also, the
62 behavior of some settings is defined by the setting's suffix;
63 the prefix identifies which module the setting controls.
65 The general parsing rules are:
68 Spaces and empty lines are ignored.
70 A # sign will mark the remainder of the line as a comment.
72 Only one setting can be present on each line.
75 All settings have the following format:
79 Unless it belongs to one of the classes of settings that receive special
80 treatment, a setting will set the value of a
82 environment variable. The settings that receive special
83 treatment are listed below. Settings beginning with
85 below define the modules to be loaded and
86 may have any prefix; the prefix identifies a module.
87 All such settings sharing a common
88 prefix refer to the same module.

93 command. This type of setting cannot be processed by programs other
96 so its use should be avoided. Multiple instances of it will be processed
98 .It Ar loader_conf_files
99 Defines additional configuration files to be processed right after the
102 Name of the kernel to be loaded. If no kernel name is set, no additional
103 modules will be loaded.

117 that module will be loaded. If no name is defined (see below), the
118 module's name is taken to be the same as the prefix.
120 Defines the name of the module.
122 Defines the module's type. If none is given, it defaults to a kld module.
124 Flags and parameters to be passed to the module.
126 Commands to be executed before the module is loaded. Use of this setting
129 Commands to be executed after the module is loaded. Use of this setting
132 Commands to be executed if the loading of a module fails. Except for the
135 which aborts the bootstrap process, use of this setting should be avoided.
