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 that describes the system being configured.  Config also takes as input a file that tells it which files are needed to generate a system.  This can be augmented by a configuration-specific set of files that gives alternate files for a specific machine (see “Files”, below).  If the −p option is supplied, config will configure a system for profiling; see kgmon(8) and gprof(1).

Config should be run from the conf subdirectory of the system source (usually, /sys/conf). Config assumes that there is already a directory ../system_name created and places all its output files there.  The output of config consists of several files: ioconf.c contains a description of the I/O devices attached to the system.  Makefile is used by make(1) in building the system; header files contain the number of various devices to be compiled into the system; and swap-configuration files contain definitions for the disk areas 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 reminds you of this when it completes. 

If config issues error messages, fix the problems and try again.  Do not compile a system that had configuration errors.
