From 753bfb85eae7184901a5183227d1a36044c485b4 Mon Sep 17 00:00:00 2001
From: Bruce M Simpson <bms@FreeBSD.org>
Date: Wed, 14 May 2008 10:02:37 +0000
Subject: Rewrite the RC script.

The xorp port will now log to /var/log/xorp_rtrmgr.log by default, and
the xorp_rtrmgr process will be run under daemon(8) to detach it from
the controlling terminal.
