.SH NAME
sysdef \- output system definition
.SH SYNOPSIS
.LP
.nf
\fB/usr/sbin/sysdef\fR [\fB-i\fR] [\fB-n\fR \fInamelist\fR]
.fi

.LP
.nf
\fB/usr/sbin/sysdef\fR [\fB-h\fR] [\fB-d\fR] [\fB-i\fR] [\fB-D\fR]
.fi

.SH DESCRIPTION
.sp
.LP
The \fBsysdef\fR utility outputs the current system definition in tabular form.
It lists all hardware devices, as well as pseudo devices, system devices,
loadable modules, and the values of selected kernel tunable parameters.
.sp
.LP
It generates the output by analyzing the named bootable operating system file
(\fInamelist\fR) and extracting the configuration information from it.
.sp
.LP
The default system \fInamelist\fR is \fB/dev/kmem\fR.
.SH OPTIONS
.sp
.ne 2
.na
\fB\fB-i\fR\fR
.ad
.RS 15n
Prints the configuration information from \fB/dev/kmem\fR. This is the default
and only needs to be specified if the configuration information from both
\fB/dev/kmem\fR and the system file specified with the "\fB-n\fR
\fInamelist\fR" option is needed.
.RE

.sp
.ne 2
.na
\fB\fB-n\fR \fInamelist\fR\fR
.ad
.RS 15n
Specifies a \fInamelist\fR other than the default (\fB/dev/kmem\fR). The
\fInamelist\fR specified must be a valid bootable operating system.
.RE

.sp
.ne 2
.na
\fB\fB-h\fR\fR
.ad
.RS 15n
Prints the identifier of the current host in hexadecimal. If \fBsysdef\fR
\fB-h\fR is executed  within a non-global zone and the zone emulates a host
identifier, then the zone's host identifier is printed. This numeric value is
not guaranteed to be unique.
.RE

.sp
.ne 2
.na
\fB\fB-d\fR\fR
.ad
.RS 15n
The output includes the configuration of system peripherals formatted as a
device tree.
.RE

.sp
.ne 2
.na
\fB\fB-D\fR\fR
.ad
.RS 15n
For each system peripheral in the device tree, display the name of the device
driver used to manage the peripheral.
