NAME

  config - Builds system configuration files


SYNOPSIS

  /sys/conf/config [-k] [-p] [-q] [system_name]


OPTIONS

  -k  Creates a define variable 'KDEBUG' that can be used to conditionally
      compile source code for kernel debugging.

  -p  Configure the system for profiling.  You must have sources to use this
      option.

  -q  Concatenates and displays all the system configuration files, including
      any configuration files described in the /sys/conf/NAME.list file.


DESCRIPTION

  The doconfig command calls the config command to build a set of system
  configuration files from a file that describes the sort of system that is
  being configured.  The config command also takes as input another file that
  tells it what files are needed to generate a system. This other file can be
  augmented by a configuration-specific set of files that name alternate
  files for a specific machine.

  Normally, you should run the doconfig program and not the config command.
  If you need to issue the config command, be sure to change your directory
  to the /sys/conf directory. As an argument to the config command, specify
  the name of a system configuration file containing device specifications,
  configuration options and other system operands for that specific system
  configuration. The config command places all its output files in the
  directory ../system_name.

  The output of config consists of a number of files; each machine type has
  its own specific set of files.  All machine types have a makefile which is
  used by make during the system build.	 Typically, there are also a set of
  header files which contain definitions of the number of various devices
  that will be compiled into the system, and a set of swap configuration
  files contain definitions for the disk areas to be used for swapping, the
  root file system, argument processing, and system dumps.

  After running config, you run make depend in the directory where the new
  makefile was created.

  If any other error messages are produced by config, the problems in the
  configuration file should be corrected and config should be run again.
  Attempts to compile a system that had configuration errors are likely to be
  unsuccessful.


NOTES

  The line numbers reported in error messages are usually off by one.
