22: .SH NAME
23: config \- build system configuration files
24: .SH SYNOPSIS
25: .B config
26: [
27: .B \-p
28: ]
29: .I SYSTEM_NAME
30: .SH DESCRIPTION
31: .PP
32: .I Config
33: builds a set of system configuration files from a short file which describes
34: the sort of system that is being configured. It also takes as input a file
35: which tells
36: .I config
37: what files are needed to generate a system.
38: This can be augmented by a configuration specific set of files
39: that give alternate files for a specific machine.
40: (see the FILES section below)
41: If the
42: .B \-p
43: option is supplied,
44: .I config
45: will configure a system for profiling; c.f.
46: .IR kgmon (8)
47: and
48: .IR gprof (1).
49: .PP
50: .I Config
51: should be run from the
52: .B conf
53: subdirectory of the system source (usually /sys/conf).
54: Its argument is the name of a system configuration file
55: containing device specifications, configuration options
56: and other system parameters for one system configuration.
57: .I Config
58: assumes that there is already a directory
59: .I "../SYSTEM_NAME"
60: created and it places all its output files in there.
61: The output of
62: .I config
63: consists of a number of files; for the VAX, they are:
64: .B ioconf.c
65: contains a description
66: of what I/O devices are attached to the system,;
67: .B ubglue.s
68: contains a set of interrupt service routines for devices
69: attached to the UNIBUS;
70: .B ubvec.s
71: contains offsets into a structure used for counting per-device interrupts;
72: .B Makefile
73: is a file used by
74: .IR make (1)
75: in building the system; a set of header files contain definitions of
76: the number of various devices that will be compiled into the system;
77: and a set of swap configuration files contain definitions for
78: the disk areas to be used for swapping, the root file system,
79: argument processing, and system dumps.
80: .PP
81: After running
82: .IR config ,
83: it is necessary to run ``make depend'' in the directory where the new makefile
84: was created.
85: .I Config
86: prints a reminder of this when it completes.
87: .PP
88: If any other error messages are produced by
89: .I config,
90: the problems in the configuration file should be corrected and
91: .I config
92: should be run again.
93: Attempts to compile a system that had configuration errors
94: are likely to meet with failure.
95: .SH FILES
96: .nf
97: /sys/conf/Makefile.vax generic makefile for the VAX
98: /sys/conf/files list of common files system is built from
99: /sys/conf/files.vax list of VAX specific files
100: /sys/conf/devices.vax name to major device mapping file for the VAX
101: /sys/conf/files.ERNIE list of files specific to ERNIE system
