From c1b05c7986816ffa4e3ddecd545584d8c626f7d9 Mon Sep 17 00:00:00 2001
From: "Jordan K. Hubbard" <jkh@FreeBSD.org>
Date: Thu, 17 Nov 1994 14:12:38 +0000
Subject: [PATCH] 1. Add check to see if CPIO floppy extracted properly. 2. See
 if swapon() failed and at least print a diagnostic. 3. Use -1 instead of
 strheight()/strwidth() everywhere.
