.Os
|
|
.Sh NAME
|
|
.Nm loader.conf
|
|
.Nd "system bootstrap configuration information"
|
|
.Sh DESCRIPTION
|
|
The file
|
|
.Nm
|
|
contains descriptive information on bootstrapping the system.
|
|
Through
|
|
it you can specify the kernel to be booted, parameters to be passed to
|
|
it, and additional modules to be loaded; and generally set all variables
|
|
described in
|
|
.Xr loader 8 .
|
|
.Pp
|
|
The file
|
|
.Pa /boot/loader.rc
|
|
must contain the following two lines for
|
|
.Nm
|
|
to be automatically processed:
|
|
.Pp
|
|
.Dl include /boot/loader.4th
|
|
.Dl start
|
|
.Pp
|
|
If no
|
|
.Pa /boot/loader.rc
|
|
exists at installworld time, one with the above lines will be installed.
|
|
.Sh SYNTAX
|
|
Though
|
|
.Nm Ns 's
|
|
format was defined explicitly to resemble
|
|
.Xr rc.conf 5 ,
|
|
and can be sourced by
|
|
.Xr sh 1 ,
|
|
some settings are treated in a special fashion.
|
|
Also, the
|
|
behavior of some settings is defined by the setting's suffix;
|
|
the prefix identifies which module the setting controls.
|
|
.Pp
|
|
The general parsing rules are:
|
|
.Bl -bullet
|
|
.It
|
|
Spaces and empty lines are ignored.
|
|
.It
|
|
A # sign will mark the remainder of the line as a comment.
|
|
.It
|
|
Only one setting can be present on each line.
|
|
.El
|
|
.Pp
|
|
All settings have the following format:
|
|
.Pp
|
|
.Dl variable="value"
|
|
.Pp
|
|
Unless it belongs to one of the classes of settings that receive special
|
|
treatment, a setting will set the value of a
|
|
.Xr loader 8
|
|
environment variable.
|
|
The settings that receive special
|
|
treatment are listed below.
|
|
Settings beginning with
|
|
.Qq *
|
|
below define the modules to be loaded and
|
|
may have any prefix; the prefix identifies a module.
|
|
All such settings sharing a common
|
|
prefix refer to the same module.
|
|
.Bl -tag -width Ar
|
|
.It Ar exec
|
|
Immediately executes a
|
|
.Xr loader 8
|
|
command.
|
|
This type of setting cannot be processed by programs other
|
|
than
|
|
.Xr loader 8 ,
|
|
so its use should be avoided.
|
|
Multiple instances of it will be processed
|
|
independently.
|
|
.It Ar loader_conf_files
|
|
Defines additional configuration files to be processed right after the
|
|
present file.
|
|
.It Ar kernel
|
|
Name of the kernel to be loaded.
|
|
If no kernel name is set, no additional
|
|
modules will be loaded.
|
|
.It Ar kernel_options
|
|
Flags to be passed to the kernel.
|
|
.It Ar password
|
|
Provides a password to be required by check-password before execution is
|
|
allowed to continue.
|
|
.It Ar verbose_loading
|
|
If set to
|
|
.Dq YES ,
|
|
module names will be displayed as they are loaded.
|
|
.It Ar *_load
|
|
If set to
|
|
.Dq YES ,
|
|
that module will be loaded.
|
|
If no name is defined (see below), the
|
|
module's name is taken to be the same as the prefix.
|
|
.It Ar *_name
|
|
Defines the name of the module.
|
|
.It Ar *_type
|
|
Defines the module's type.
|
|
If none is given, it defaults to a kld module.
|
|
.It Ar *_flags
|
|
Flags and parameters to be passed to the module.
|
|
.It Ar *_before
|
|
Commands to be executed before the module is loaded.
|
|
Use of this setting
|
|
should be avoided.
|
|
.It Ar *_after
|
|
Commands to be executed after the module is loaded.
|
|
Use of this setting
|
|
should be avoided.
|
|
.It Ar *_error
|
|
Commands to be executed if the loading of a module fails.
|
|
Except for the
|
|
special value
|
|
.Dq abort ,
|
|
which aborts the bootstrap process, use of this setting should be avoided.
|
|
.El
|
|
.Pp
|
|
.Em WARNING:
|
|
developers should never use these suffixes for any kernel environment
|
|
variables (tunables) or conflicts will result.
|
|
.Sh DEFAULT SETTINGS
|
|
Most of
|
|
.Nm Ns 's
|
|
default settings can be ignored.

|
