INTRODUCTION

.PP

|
.I Config
|
|
is a tool used in building 4.4BSD system images (the UNIX kernel).
|
|
It takes a file describing a system's tunable parameters and
|
|
hardware support, and generates a collection
|
|
of files which are then used to build a copy of UNIX appropriate
|
|
to that configuration.
|
|
.I Config
|
|
simplifies system maintenance by isolating system dependencies
|
|
in a single, easy to understand, file.
|
|
.PP
|
|
This document describes the content and
|
|
format of system configuration
|
|
files and the rules which must be followed when creating
|
|
these files. Example configuration files are constructed
|
|
and discussed.
|
|
.PP
|
|
Later sections suggest guidelines to be used in modifying
|
|
system source and explain some of the inner workings of the
|
|
autoconfiguration process. Appendix D summarizes the rules
|
|
used in calculating the most important system data structures
|
|
and indicates some inherent system data structure size
|
|
limitations (and how to go about modifying them).
