CONFIG(8)               386BSD System Manager's Manual               CONFIG(8)

NAME
     config - build system configuration files

SYNOPSIS
     config [-p] SYSTEM_NAME

DESCRIPTION
     Config builds a set of system configuration files from the file
     SYSTEM_NAME which describes the system to configure.  A second file tells
     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 FILES section below)

     Available option and operand:

     -p           If the -p option is supplied, config will configure a system
                  for profiling; for example, kgmon(8) and gprof(1).

     SYSTEM_NAME  specifies the name of the system configuration file
                  containing device specifications, configuration options and
                  other system parameters for one system configuration.

     Config should be run from the conf subdirectory of the system source
     (usually /sys/conf). Config assumes the directory ../SYSTEM_NAME exists
     and places all output files there.  The output of config consists of a
     number of files; for the VAX, they are: ioconf.c, a description of what
     I/O devices are attached to the system; ubglue.s, a set of interrupt
     service routines for devices attached to the UNIBUS; ubvec.s, offsets
     into a structure used for counting per-device interrupts; Makefile, used
     by 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.

     After running config, it is necessary to run ``make depend'' in the
     directory where the new makefile was created.  Config prints a reminder
     of this when it completes.

     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
     fail.

FILES
     /sys/conf/Makefile.vax  generic makefile for the VAX
     /sys/conf/files         list of common files system is built from
     /sys/conf/files.vax     list of VAX specific files
     /sys/conf/devices.vax   name to major device mapping file for the VAX
     /sys/conf/files.ERNIE   list of files specific to ERNIE system
