If you invoke config with the `-n' flag or have NO_CONFIG_CLOBBER in your environment, config will behave the same way it used to. This is now _documented_ as well. Rip out all the CONFIG_DONT_CLOBBER cruft; some of it wasn't even correct anyway.

|
|
.Nm config
|
|
.Op Fl gpn
|
|
.Ar SYSTEM_NAME
|
|
.Sh DESCRIPTION
|
|
.Pp
|
|
This is the old version of the
|
|
.Nm config
|
|
program.
|
|
It understands the old autoconfiguration scheme
|
|
used on the HP300, i386, DECstation, and derivative platforms.
|
|
The new version of config is used with the
|
|
SPARC platform.
|
|
Only the version of
|
|
.Nm config
|
|
applicable to the architecture that you are running
|
|
will be installed on your machine.
|
|
.Pp
|
|
.Nm Config
|
|
builds a set of system configuration files from the file
|
|
.Ar SYSTEM_NAME
|
|
which describes
|
|
the system to configure.
|
|
A second file
|
|
tells
|
|
.Nm config
|
|
what files are needed to generate a system and
|
|
can be augmented by configuration specific set of files
|
|
that give alternate files for a specific machine.
|
|
(see the
|
|
.Sx FILES
|
|
section below)
|
|
.Pp
|
|
Available options and operands:
|
|
.Pp
|
|
.Bl -tag -width SYSTEM_NAME
|
|
.It Fl g
|
|
If the
|
|
.Fl g
|
|
option is supplied,
|
|
.Nm config
|
|
will configure a system for debugging.
|
|
.It Fl p
|
|
If the
|
|
.Fl p
|
|
option is supplied,
|
|
.Nm config
|
|
will configure a system for profiling; for example,
|
|
.Xr kgmon 8
|
|
and
|
|
.Xr gprof 1 .
|
|
.It Fl n
|
|
If the
|
|
.Fl n
|
|
flag is specified,
|
|
.Nm config
|
|
will not remove the old compile directory (see below).
|
|
.It Ar SYSTEM_NAME
|
|
specifies the name of the system configuration file
|
|
containing device specifications, configuration options
|
|
and other system parameters for one system configuration.
|
|
.El
|
|
.Pp
|
|
.Nm Config
|
|
should be run from the
|
|
.Pa conf
|
|
subdirectory of the system source (usually
|
|
.Pa /sys/ARCH/conf ) .
|
|
.Nm Config
|
|
will create the directory
|
|
.Pa ../../compile/SYSTEM_NAME
|
|
as necessary and place all output files there.
|
|
If the directory already exists, it will be removed
|
|
first unless the
|
|
.Pa -n
|
|
flag was specified or the environment variable
|
|
.Nm NO_CONFIG_CLOBBER
|
|
is set.
|
|
The output of
|
|
.Nm config
|
|
consists of a number of files; for the
|
|
.Tn i386 ,
|
|
they are:
|
|
.Pa ioconf.c ,
|
|
a description
|
|
of what I/O devices are attached to the system;
|
|
.Pa vector.h ,
|
|
definitions of
|
|
macros related to counting interrupts;
|
|
.Pa Makefile ,
|
|
used by
|
|
.Xr make 1
|
|
in building the system;
|
|
header files,
|
|
definitions of
|
|
the number of various devices that will be compiled into the system;
|
|
swap configuration files,
|
|
definitions for
|
|
the disk areas to be used for swapping, the root file system,
|
|
argument processing, and system dumps.
|
|
.Pp
|
|
After running
|
|
.Nm config ,
|
|
it is necessary to run
|
|
.Dq Li make depend
|
|
in the directory where the new makefile
|
|
was created.
|
|
.Nm Config
|
|
prints a reminder of this when it completes.
|
|
.Pp
|
|
If any other error messages are produced by
|
|
.Nm config ,
|
|
the problems in the configuration file should be corrected and
|
|
.Nm config
|
|
should be run again.
|
|
Attempts to compile a system that had configuration errors
|
|
are likely to fail.
