.nf
\fB/usr/lib/hal/hald\fR [\fB--daemon\fR={\fByes\fR | \fBno\fR}]] [\fB--help\fR] [\fB--use-syslog\fR]

.SH DESCRIPTION
.sp
.LP
The \fBhald\fR daemon supports the recognition of hardware changes for devices
that conform to the Hardware Abstraction Layer (HAL) specification.
.sp
.LP
The enabling and disabling of \fBhald\fR can be performed through the service
management facility (SMF) (see \fBsmf\fR(5)). \fBhald\fR is managed using the
fault management resource identifier (FMRI) \fBsvc:/system/hal\fR. Options can
be specified as SMF properties. See EXAMPLES.
