CONFIG(8)                                                            CONFIG(8)


NAME
       config - build system configuration files

SYNOPSIS
       /etc/config [ -p ] SYSTEM_NAME

DESCRIPTION
       Config  builds  a  set  of system configuration files from a short file
       which describes the sort of system that is being configured.   It  also
       takes  as input a file which tells config what files are needed to gen‐
       erate a system.  This can be augmented by a configuration specific  set
       of  files  that  give alternate files for a specific machine.  (see the
       FILES section below) If the -p option is supplied, config will  config‐
       ure a system for profiling; c.f.  kgmon(8) and gprof(1).

       Config  should  be  run from the conf subdirectory of the system source
       (usually /sys/conf).  Its argument is the name of a  system  configura‐
       tion  file  containing device specifications, configuration options and
       other system parameters for one system configuration.   Config  assumes
       that  there is already a directory ../SYSTEM_NAME created and it places
       all its output files in there.  The output of config consists of a num‐
       ber of files; for the VAX, they are: ioconf.c contains a description of
       what I/O devices are attached to the system,; ubglue.s contains  a  set
       of  interrupt  service  routines  for  devices  attached to the UNIBUS;
       ubvec.s contains offsets into a structure used for counting  per-device
       interrupts;  Makefile is a file used by make(1) in building the system;
       a set of header files contain definitions  of  the  number  of  various
       devices  that  will be compiled into the system; and a set of swap con‐
       figuration files contain 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 meet with failure.

FILES

       /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
