.SH NAME
syseventd \- kernel system event notification daemon
.SH SYNOPSIS
.LP
.nf
\fB/usr/lib/sysevent/syseventd\fR [\fB-d\fR \fIdebug_level\fR] [\fB-r\fR \fIrootdir\fR]
.fi

.SH DESCRIPTION
.sp
.LP
\fBsyseventd\fR is a user-level daemon that accepts delivery of system event
buffers from the kernel. Once an event buffer has been delivered to
\fBsyseventd\fR, it, in turn, attempts to propagate the event to all interested
end event subscribers.
.sp
.LP
Event subscribers take the form of a \fBsyseventd\fR loadable module
(\fBSLM\fR). \fBsyseventd\fR passes the event buffer to each of its subscribers
and in return expects a notification as to the successful or unsuccessful
delivery attempt.
.sp
.LP
Upon successful delivery of the event buffer to all interested event
subscribers, \fBsyseventd\fR frees the event buffer from the kernel event
queue.
