From 0d07a17653cfe4950880cf898beb23cbac18d6e4 Mon Sep 17 00:00:00 2001
From: Mark Huang <mlhuang@cs.princeton.edu>
Date: Thu, 14 Oct 2004 18:25:05 +0000
Subject: [PATCH] - move functionality into /etc/init.d/vserver-reference,
 which runs once after installation (and maybe again if the RPM is ever
 updated, but the script is mostly idempotent).
