From: Kenneth R Westerback <krw@cvs.openbsd.org>
Date: Thu, 30 Apr 2009 00:45:01 +0000
Subject: Prime mountpoint info with any fstab info that is available, with or
 without the '-f' option being present. Now you can see in Editor mode or
 'disklabel <dev>' where the partitions that exist will be mounted in the
 current configuration.

Tweaks (and libc fixes) from, and ok deraadt@
