From beef52db542af4e29d7fc06e2f615b02be8517b2 Mon Sep 17 00:00:00 2001
From: Poul-Henning Kamp <phk@FreeBSD.org>
Date: Mon, 31 Oct 1994 23:45:40 +0000
Subject: [PATCH] Changed RAW_PART to RAWPART so it comes from disklabel.h.
 Force RAW_PART to have the right size. Set d_secperunit in the disklabel.
