From 8c03cb3e1afb199716381f536c8b9539e2930e9d Mon Sep 17 00:00:00 2001
From: Miod Vallat <miod@cvs.openbsd.org>
Date: Sun, 1 Jul 2007 19:06:59 +0000
Subject: Perform minimal disklabel setup without needing to do the
 disklabel_to_sun() dance, so that we do not depend on its behaviour. No
 functional change.
