From 91cc63d0c0bd148b5a03490dc0b4781979e16d08 Mon Sep 17 00:00:00 2001
From: David Nugent <davidn@FreeBSD.org>
Date: Fri, 3 Jan 1997 04:42:18 +0000
Subject: Implemented /home -> /usr/home symlink kludge. If home basedir would
 be created in the root partition, create it under /usr instead, and symlink
 /basedir -> /usr/basedir.
