.TH SYSDEF 1M
.SH NAME
sysdef \- system definition
.SH SYNOPSIS
.B /etc/sysdef
[\^opsys\|[\^master\^]\^]
.SH DESCRIPTION
.I Sysdef\^
analyzes the named operating system
file and extracts configuration information.
This includes all hardware devices, their
addresses, interrupt vectors and unit count,
as well as system devices and all tunable parameters.
.PP
The output of
.I sysdef\^
can be used directly by
.IR config (1M)
to regenerate the appropriate
.B low.s
.RB ( univec.c
on the
.SM VAX\*S-11/780)
and
.B conf.c
configuration files.
.SH FILES
/unix		default operating system file
.br
/etc/master	default table for hardware specifications
.SH DIAGNOSTICS
``unknown device interrupts at vector xxx'' if information
regarding the device cannot be found in the master table.
.SH "SEE ALSO"
config(1M), master(5).
.SH BUGS
As yet,
.I sysdef\^
knows nothing of devices that are not interrupt driven.
.br
Because information regarding
.I config\^
aliases is not preserved by the system,
device names returned might not be accurate.
